The internet is filled with testimonials from people who have supposedly stuck with it long enough to lose 50 lbs or more in just a few months. Combined with the perception of scientific validity, it’s no wonder why this is the latest fad. But take a closer look and you will see that it isn’t all it claims to be. First, if one is trying to lose weight, they should be striving to lose fat weight. The scale does not tell us what kind of weight we are losing. Our body is about 60% water by weight. Carbohydrate is stored in our body as a substance called glycogen, which is found mostly in muscle and liver cells. Each gram of glycogen we store is accompanied by two grams of water. When we restrict carbohydrate intake, glycogen levels are depleted, and we rapidly lose a lot of water weight via increased urination. This does not make us healthier, but it does make us somewhat dehydrated.|This article was medically reviewed by Rachel Lustgarten, R.D., C.D.N., a clinical dietitian and member of the Prevention Medical Review Board. The keto diet has blown up as an ultra-low carb eating plan that can help you drop pounds fast-but its effects on your body go beyond weight loss. A typical keto diet is comprised of 80% fat, 15% protein, and a mere 5% of calories from carbohydrates. If you consume 2,000 calories a day, that means just 100 of them are coming from carbs-including healthy carbs like fruits and vegetables. When you eat this way, it triggers ketosis, which means your body has burned through all its carbs and needs to begin burning fat for energy. It’s true: Following a strict high-fat, low-carb regimen can help move the number on the scale, but there might be some other keto diet side effects that you aren’t aware of. Some of them are positives, but a few could be unpleasant-or even dangerous. Here’s what you should know about keto diet dangers before you decide to try it for yourself. By slowly lowering your carbohydrate intake, while gradually increasing your intake of dietary fat over time, you can transition with less of a negative impact and potentially prevent the keto flu. The removal of many grains and fruits with such a large emphasis on fats can bring about its own set of gastrointestinal side effects. Keto constipation and diarrhea aren't uncommon. Further, eliminating food groups can be problematic. “Ketogenic diets are often low in calcium, vitamin D, potassium, magnesium, and folic acid, which over time can lead to nutrient deficiencies if the diet is not planned carefully,” adds Marie Spano, RD, CSCS, who is based in Atlanta. Reliance on a diet rich in animal fats and proteins may also have a negative impact on heart health, research shows. 6) “This diet is not for anyone who is at risk of developing cardiovascular disease or who has already been diagnosed with it,” Spano cautions. This means that if you have risk factors for heart disease - such as elevated cholesterol levels, high blood pressure (hypertension), or a strong family history of the disease - you should use caution when following this diet. The average person doesn’t fully understand what ketosis really means, or that it’s necessary to measure blood levels of ketones. The mere presence of a few ketones doesn’t make one in ketosis. And peeing on a stick isn’t the way to measure blood levels of ketones, because simply spilling a few ketones in urine isn’t indicative of ketosis. After all, we all produce ketones after a certain period of not eating. That doesn’t mean that our body is magically shifting gears and the ketones are changing how we’re oxidizing all the food in our bodies. The ketogenic diet’s extreme restriction of carbohydrates contributes to micronutrient deficiencies and impacts gut health. Ketogenic diets don’t just eliminate sugar and refined carbohydrates; they also cut out pulses, whole grains, fruit, and starchy vegetables. All of these foods contribute vitamins, minerals, antioxidants, phytochemicals, and fiber which include prebiotic fiber that promotes a healthy gut microbiota.|“I don’t recommend staying on the keto diet permanently. It can be really restrictive,” says Mancinelli. Long-term research on the keto diet is limited, so there’s no telling for sure what cutting out certain major food groups and cutting carbs will eventually do to your body. Registered dietitians warn that nutrient deficiencies may be possible if you’re on it for too long. Stick to the keto diet for three to six months max, says Mancinelli, noting that some people opt to cycle in and out of the diet throughout the year. Because it’s not a forever diet, there will be life after keto. But even when you go off it, you can expect that your taste preferences will have changed. “You likely won’t want as many carbs, and things will taste extremely sweet,” she says. That’s good, because the last thing you want to do is go back to your old eating habits and regain weight that you lost. While everyone’s nutrition requirements differ, generally, you may eat 40 to 45 percent fat and stick to 120 to 150 g of carbs per day to help you keep the weight off, she says. That said, the US News report noted that the long-term weight loss effects of keto aren’t clear. The aim of the diet is to keep up the state of ketosis for longer periods, by not eating much carbohydrate. And when we say not much, we mean almost nothing at all. For an effective keto diet, you must cover no more than 5% of your daily calorie intake from carbs. Keto vs low carb diet: which one is better for weight loss and exercising? What do you eat on a keto diet? The tricky part is, for an average person, carbs tend to form the majority of their energy intake and switching from a high-carb diet to a high-fat diet will require some willpower. Good news is, you can gorge yourself on good fats during keto diet, like certain types of cheese and avocados. Also, if you are a fan of seafood, you are up for a treat: foodstuff like clams, oysters and squid contain very little carbs and therefore can be consumed more freely when doing keto.|The Keto Diet, or Ketogenic Diet is a high-fat diet that is moderate in protein and low in carbohydrates. This macro-nutrient ratio allows the body to switch from using carbohydrates (converted into glycogen in the liver) for energy, to using fat (converted into fatty acids and ketone bodies in the liver). The human body is like a hybrid vehicle, relying on either carbohydrates or fat for fuel. For the most part, it cannot use both fuels simultaneously. Consuming fat allows the body to access hundreds of thousands of calories of stored fats that have been locked away during carbohydrate metabolism. In addition to burning fat reserves and super charging weight loss, ketosis produces a clean burning metabolic fuel that has many benefits. Ketones lower production of reactive oxygen species (ROS),1 enhance mitochondrial biogenesis,2 3 and induce positive epigenetic expression.4 Because of its neurological benefits, I went on a Keto Diet in 2014, and it has been helpful in moderating my MS symptoms. However, if you listen to your body, you’ll likely pick up on a few tell-tale signs of ketosis. Rest assured, these symptoms typically only occur during the first 1-2 weeks of beginning a ketogenic diet and go away once your body starts to adjust. Once you reach this sweet spot, you’ll understand why the keto diet can be so rewarding and life-changing! Head over here for more information on the signs of ketosis.

This will determine the nutrient density of the ketogenic diet as well as how to follow it, as different foods will have different effects on insulin and blood sugar levels. There are a number of different types of ketogenic diet with variations in the level of carbohydrates and protein allowed in the diet and/or the amount of time someone is looking to spend in ketosis. Note that some of the types of ketogenic have been designed specifically for people that are athletes or are otherwise working out very hard and often. Ketone bodies produced from burning fat for fuel have been shown to have potent weight loss effects, help lower blood glucose levels and reduce people’s reliance on diabetes medication. In addition to that, there has been a lot of interest in therapeutic ketosis for other long-term conditions, such as cancer, epilepsy, Alzheimer’s disease or dementia. Do I need to measure ketones? Significant weight loss and blood glucose control benefits can be derived from even a mild state of ketosis. There are a few methods you can use to measure the levels of ketones in your blood, urine or breath - each having their pros and cons. With every change in the diet comes an adaptation period. With a ketogenic diet, the adaption is significant as the body has to switch its fuel source from glucose to fat. When this happens, it is not uncommon to experience a collection of side effects called ‘keto-flu’. This usually goes away within about four weeks. She warns not to try this (or any version of keto) before talking with a physician if you have diabetes and are insulin dependent, as it could lead to a too-low blood sugar level. How It Works This version of keto calls for upping the protein intake just a bit. Protein should make up about 30 percent of calories, with the other 65 percent coming from fat and 5 percent from carbs, Spritzler says. Aim to source your protein from both animals (meat, fish, and dairy) and plants (nuts and seeds), Spritzler suggests. Who It's Best For This is meant for those who need protein to help protect muscle mass, like bodybuilders and older people who need to prevent muscle breakdown, Spritzler says. It’s also a good option for those who show signs of a protein deficiency. Those signs include a loss of muscle or thinning hair, according to the subcommittee on the 10th edition of the federal recommended dietary allowances. The diet works in the following way. First Step - You will have to fill in a few pieces of data about yourself. These include your age, gender, food preferences, workout intensity, weight, height, and desired weight. This helps the website understand your present status to analyze required calories, activity level, BMI, nutrition intake. This is the initial step to help prepare your exclusive Custom Keto Diet plan. Second Step - After filling in the data and going through the analytics, you will be asked to enter your name and mail id after which you will be taken to the payment portal. Once you have purchased the plan, you will receive a mail with your custom keto diet plan. Third Step - The final step is to keep up consistency in following the plan. You mustn’t break in between. Be it the meal plans, or workout routines stick to the planner so that you can lose weight healthily.
What I didn’t know back then was that my diet was actually making me hungrier. When we mix carbohydrates and fats in the same meal, we actually want to eat more. It’s the reason that you could eat cake or cookies until you’re sick (because they’re full of sugar and fat from butter), but you usually won’t do the same with steak (which is mostly protein with some fat). Remember how I talked about “poor metabolic flexibility” above? Well, if you have poor metabolic flexibility, then eating carbohydrates is almost always going to make you hungry an hour or two after a meal. So while you’re eating more calorie-dense fats on a keto diet plan, most people find that they end up eating less overall (in terms of calories), without trying as hard. And they’re less hungry, which usually also means they’re happier and less moody. Generally, if you’re less hungry when you’re on a diet, you’re more likely to stick with it, so your chances of losing weight long term are higher.|See our keto food list for more information on the kinds of foods you should avoid on keto, and our guide on dirty keto to learn more on the foods that are technically within the ketogenic diet but could be affecting other parts of your lifestyle. You’ll also want to learn about calculating net carbs to make sure the “keto-friendly” product you’re about the consume really does fit in your keto diet, as well as what sweeteners work best with keto. The keto diet isn’t all bacon and lettuce-wrapped burgers. You can still enjoy delicious, low-carb foods you’ll look forward to eating as part of your keto meal plan. There are even keto-friendly versions of your favorite carb-heavy foods, like pancakes and desserts. Here are a few of our favorite low-carb recipes. Browse Bulletproof Recipes to find more keto-friendly meal ideas. Start your day with quality fats that keep you going strong all morning long. To whip up this keto coffee recipe, you’ll blend grass-fed butter or Grass-Fed Ghee with certified clean Bulletproof coffee beans and Brain Octane C8 MCT Oil to create a creamy, frothy latte that’ll keep you energized and satisfied. Weight loss isn’t worth anything if you can’t keep it off. Ketogenic diets appear to be good for long-term maintenance of weight loss. The bulk of your food intake (in terms of volume) should come from “above-ground” vegetables-those that grow above the ground like greens, peppers, broccoli, Brussels sprouts, cauliflower, tomatoes, celery, cucumber, kale, cabbage, asparagus, zucchini, mushrooms and avocado. You’re also free to enjoy virtually any fish or meat that doesn’t contain added breading or sweeteners. Eggs are also an ideal choice. In fact, many people often don’t eat enough protein while trying a keto diet. While an overabundance of protein can inhibit ketosis, this isn’t an issue most people would deal with. The average American, particularly older men and women, don’t eat enough protein for their muscle maintenance needs. Bone broth and collagen supplements that don’t contain carb sources like sugars, fillers or binders are also healthy choices while keto. The majority of your calories on a keto diet will come from fat. This makes certain vegetables easier to digest than in their raw form. Cooking also gives you the chance to add fat and flavor. A little oil, plus some pink Himalayan salt and pepper, can radically transform a tasteless raw vegetable into something more crave-worthy. In the end, it’s smart to enjoy vegetables both ways. During the summer, you may want a nice cold salad with spinach, while in the winter sauteed spinach with garlic may sound better. Check out the Best Vegetables to Eat on a Keto Diet for more information when it comes to eating your veggies. Many new keto dieters are surprised to learn that fruits and fruit juices contain as many grams of carbs and sugar as some desserts. Bananas and apples, two of the most popular fruits in the United States, contain 24g and 20g of net carbs, respectively. That’s your entire carb count for the day in just one fruit! Whereas most keto dieters focus on meat, eggs, vegetables, and healthy fats, dirty keto dieters will eat anything as long as they can keep their carbs down. Do you count sugar alcohols on keto? It’s up to you. Erythritol, a common ingredient in keto-friendly baking, has a negligible impact on blood sugar and insulin levels, so it shouldn’t disrupt ketosis. Other sugar alcohols (sweeteners ending in -ol, like sorbitol and xylitol) are similar. In that sense, they don’t count against your carb limit. The one exception is malitol, which has a slightly higher glycemic index (a measure of a food’s effect on blood sugar), though it’s still well below table sugar. Many keto dieters choose to disregard the carbs in sugar alcohols. Diabetics are often advised to count half the carbs. Remember, though, even if you decide the carbs don’t count, consuming too many keto-fied desserts can still negatively affect your health and body composition goals. The calories in keto-friendly cookies, cakes, muffins, and the like do still matter.
The ketogenic diet is an ultra-low-carbohydrate, high-fat diet that has been used for decades to treat certain medical conditions. Today, adherents claim that it will help you drop pounds while boosting your energy levels and controlling your blood sugar. Its promise of fast and aggressive weight loss is a compelling one in our world of quick fixes, but the ketogenic diet can be complicated in its execution and the research of its long-term benefits and drawbacks is ongoing. “Most people’s expectations are to lose weight with this diet. However, whether this is a sustainable strategy has yet to be determined. I advocate for whole health and taking care of all aspects of it, not just dropping weight,” says Colin Zhu, DO, a family physician who specializes in lifestyle medicine. Here are five fast facts about the ketogenic diet-including its pros and cons. 1. Burning fat: On most diets, the body uses glucose as its primary energy source. This will require some work but your muscle mass gain should come with less fat gain it would if you were to consume a normal about of carbohydrates. Research results are mixed when it comes to the true long term effects of the maintenance of a keto diet for strength and performance. Your results will depend on how your body reacts, what you are training for, and how you train. Because glycogen is required for these explosive sports, those who do explosive sports such as weightlifting and sprinting are not likely to benefit as much as the typical gym goer. To keep things in check, I recommend having a re-feed day every two to four weeks to keep your hormone levels in check and to keep your fuel levels high. Some people (usually naturally lean individuals) can even get away with having a re-feed every week. Who Should Avoid the Keto Diet? Q: What do you eat on a ketogenic diet? A: A true keto diet contains 80 percent fat, fewer than 5 percent carbs and 15 to 20 percent protein. In order to achieve that, dieters have to ditch a few major carbohydrate-heavy food groups including grains, dairy, beans and fruits. When you remove those, you find yourself loading up on meat, fish, butter, eggs, avocados, oils, nuts, seeds and non-starchy vegetables. The keto diet looks very different from the diet recommended in the government’s Dietary Guidelines for Americans, which is about 20 to 30 percent protein, 45 to 65 percent carbohydrates and 10 to 35 percent fat. Q: Does it help dieters lose weight? A: Since a ketogenic diet effectively eliminates major food groups, you’re likely to lose weight - at least at first. Eating higher amounts of protein may help keep hunger pangs at bay and that’s good for dieters who want to lose weight.|Yet regardless of the doubtful outpouring, my will to enter the magical state of ketosis remained unsullied. After reading countless blog posts about fellow dieters reporting exhaustion and fatigue during the first few days, I actually noticed my energy levels soar. In fact, I felt as if I had downed three cups of coffee sans cream. At one point, the restlessness and jitters were a bit overwhelming. Though, after a few days progressed, my energy levels began to balance, and I felt more productive and clear-minded. You know when you wake up with a noticeably flatter stomach and wish it would remain that toned all day? Well, that normally transient state became quite permanent on keto. My bloating subsided, and I was convinced my abs would uncover after just a few more days on the diet-and it wasn't just all in my head. Jim White, RD, ACSM, and owner of Jim White Fitness Nutrition Studios, shares with us. So if your goal is weight loss, eat enough fat to be satisfied, but there’s no need to “get your fats in” once you’re satisfied. Drink lots of water. This is especially crucial on a low carb or keto diet. Why? When you eat carbohydrates, your body stores the extra as glycogen in the liver, where they are bound to water molecules. Eating low carb depletes this glycogen, which allows you to burn fat - but it also means you are storing less water, making it easier to get dehydrated. Instead of the traditional recommendation of 8 cups of water per day, aim for 16 cups when following a low carb lifestyle. Keep up electrolytes. The major electrolytes in our bodies are sodium, potassium and magnesium. Because a low carb diet (especially a keto diet!) reduces the amount of water you store, this can flush out electrolytes and make you feel sick (called “keto flu”). This is temporary, but you can avoid or eliminate it by salting your food liberally, drinking broth (especially bone broth), and eating pickled vegetables. Over the last several decades, we have seen a rise in the popularity of low-carbohydrate diets. These diets have ranged from just low-carb diets to ketogenic diets to even zero carb diets (e.g., The Carnivore Diet). These dietary approaches have become popular due to their effectiveness in inducing rapid weight loss due to substantial changes in eating habits and rapid water weight loss that occurs with severe carbohydrate restriction. Despite the rise in popularity, very few people understand these diets. ● What is a Ketogenic Diet? ● Are Ketogenic Diets Better for Weight Loss Than Other Diets? ● How do I Follow a Ketogenic Diet? This article will cover the fundamental science behind a ketogenic diet, how to follow it, and how to view ketogenic diets in the broader dietary landscape.

There’s a lot of confusion about just how much fat, protein, and carbohydrates you should eat, and that’s because there are now several types of keto diet plans. Most of the research has focused on the very high fat (standard) keto diet. But if you’re looking for weight loss benefits then a high-protein variation of the keto diet might be better for you. The ketogenic diet (or keto, as we call it now) was originally designed by Dr. Russell Wilder at the Mayo Clinic to help treat kids with epilepsy seizures. During the 1920s and 1930s, it got very popular as an effective way to treat epilepsy, but as anti-seizure medication became more prevalent during the 1940s, the keto diet was shelved (despite its effectiveness). In more recent years, the popularity of the low carb (or Atkins) diet has prompted a resurgence of interest into the keto diet plan, this time as a highly effective method of losing weight - and losing fat, in particular. One concern voiced in some studies is loss of muscle tissue beyond what might be expected from any calorie-restricted weight loss diet, possibly because the body is attempting to break down protein to create glucose, but Volek says this isn't an issue when the ketogenic diet is followed correctly. Could the ketogenic diet's extreme restriction of carbohydrates contribute to micronutrient deficiencies and impact gut health? Ketogenic diets don't just eliminate sugar and refined carbohydrates; they also curtail pulses, whole grains, fruit, and starchy vegetables. All of these foods contribute vitamins, minerals, antioxidants, phytochemicals, and fiber-including prebiotic fiber that promotes a healthy gut microbiota. Numerous studies have demonstrated that the ketogenic diet alters the gut microbiota in ways that have benefit for reduction of epileptic seizures,15 but research is lacking on the impact in populations using the diet for weight loss or diabetes management. Somerville, Massachusetts-based Jessi Haggerty, RDN. She also points out that when people on a ketogenic diet are consuming large quantities of nonstarchy vegetables, the excessive amounts of insoluble fiber also can lead to nutrient malabsorption. The regimen kicks the body into a natural fat-burning mode called ketosis by starving a person's system of carbs and sugars, which are typically the first fuels we burn. Some people say that being in ketosis helps them focus and decreases their appetite, while trimming belly fat. But more research is needed on the long-term effects of the high-fat diet, and anyone who wants to go keto should consult their physician first. Dieters from Silicon Valley to the Hollywood hills are convinced that the keto diet is a miracle for the body. The high-fat regimen has become the go-to eating plan for celebrities like Halle Berry and the Kardashians, Silicon Valley tech workers, venture capitalists, and sports stars like LeBron James. Fans of the diet believe it can help burn belly fat, tamp down on hunger, and increase energy, all while encouraging consumption of fatty and oily foods. The keto diet is designed to get the body into a natural fat-burning state called ketosis.|But before you order a beer at the bar hosting your Wednesday night pool league, you need to consider why you’re on the keto diet in the first place. Most people use the targeted keto diet to enhance their athleticism and recovery. Alcohol won’t help with this at all. 11. Will the Targeted Keto Diet Actually Make Me a Better Athlete? A lot of research indicates that being in a fasted state makes incredible feats of athleticism easier. Take, for instance, marathoners. They “hit a wall,” because they run out of stored glycogen and they’re not fat-adapted. Many of the world’s most successful marathoners find it easier to be fat-adapted than to consume carbs on their 26.2-mile run. 12. What Are the Primary Benefits of a Keto Diet? Regardless of the type of keto diet you choose to follow, there are some pretty significant benefits. 13. The reason that this diet helps with neurological diseases? Eating a primarily fat-based diet actually switches our neural pathways. You’ve probably heard that our brains run off glucose for energy. Our bodies also break down carbohydrates into glucose for fuel. When you starve the brain and body of glucose by heavily limiting carbohydrates, our system has to use an alternative fuel source to function. It naturally turns to ketones, which are a byproduct of ingested and stored fats. So, when you adopt a ketogenic diet, you are literally changing your brain and body’s energy source from glucose (carbs) to ketones (fat). In neurological diseases, which often occur due to an imbalance or overactivity in neural pathways, the lack of carbohydrates shifts which neural pathways are active, and this often results in a decreased symptoms. Many people with epilepsy report a reduction or elimination of seizures when they transition to a ketogenic diet. Since that discovery, keto popularity has skyrocketed, and now you hear or read about it left and right. Rebalance and re-energize with our 4-week Keto Reset Program!

If you are among the minority of people who have a healthy metabolism and good insulin response, then you don't have to worry about your carb intake. Good metabolic health means you don't struggle with some combination of issues with blood pressure, blood sugar, cholesterol, weight, or low energy. Low-carb diets can lead to weight loss, research suggests, since they can help to manage appetite and reduce sources of added calories such as sugar and refined grains. But the primary benefit of keto is restoring metabolic health, improving insulin response, and reducing inflammation, Cucuzzella said. And while weight-loss diets work by restricting calories, Cucuzzella said that could backfire if you're doing keto for the first time, making it tougher to transition to burning fat for fuel if you aren't eating enough overall. Finally, a significant amount of the quick weight loss that people can have on short-term keto diets is water, and those pounds can return when you reintroduce carbs into your diet. Low-carb diets can also be problematic if you have a difficult relationship with food, including current or previous disordered eating habits. These include feelings of anxiety about gaining weight and a compulsive need to monitor or limit food, as well as binge eating, emotional eating, or addictive eating behaviors. Any diet that restricts what you can eat can be extremely triggering for anyone with these or other forms of disordered eating, which experts say can be risky if left untreated. It's best to seek professional support when considering a new diet. It may be tempting to make a dramatic change during a tough time. But if you can't manage your stress, you're not getting enough sleep, or you recently had an upsetting life event, it's the worst time to change your diet, Cucuzzella said. The diets included the low-carb Atkins, South Beach and Zone diets as well as low-fat diets like the Ornish diet and portion-control diets like Jenny Craig and Weight Watchers. They found that any diet resulted in more weight loss than no diet at all after six months. Low-fat and low-carb diets were pretty much indistinguishable, with low-carb dieters losing 19 pounds (8.73 kilograms), on average, and low-fat dieters losing an average of 17.6 pounds (7.99 kg), both compared to non-dieters. At 12 months, the benefits showed signs of leveling off for both types of diets, with both low-fat and low-carb dieters reporting being 16 pounds (7.27 kg) lighter, on average, than non-dieters. Another analysis of popular diets published in the Annals of Internal Medicine in April 2015 found the Atkins diet to result in more weight loss than simply educating people on portion control, but also noted that most of the studies of this low-carb diet involved registered dieticians helping participants make food choices, rather than the self-directed process by which most people pick up the diets. What is the keto diet? How does keto work? Does the ketogenic diet work? What do you eat on the keto diet? Are there any ketogenic diet side effects? Is keto like other low-carb diets? How can I start the keto diet? What is the keto diet? The keto diet, also known as the ketogenic diet, is a low-carb, high-fat and moderate-protein diet. The goal of the keto diet is to shift in to a nutritional state called ketosis - where your body changes from using carbohydrates to fat to fuel weight loss. How does keto work? The ketogenic (keto) diet works by starving the body of carbohydrates. When only fat is available, your liver uses fat as an alternative fuel and turns fatty acids in to ketones. These ketones are then used by your body and brain for clean, effective energy that keeps you full - without slowing you down.|Are beans keto at all? What are some ways you can (or can’t) incorporate them? All of these inquiries are totally understandable, especially considering there is a plethora of conflicting nutrition information out there on the Internet. For answers to all of these questions and more-all according to RDs-keep reading. Tell me: Can you eat beans on a low-carb diet like keto? “Beans are a powerhouse in terms of nutrition,” says Vandana Sheth, RDN, author of My Indian Table: Quick & Tasty Vegetarian Recipes. So, even though they’re pretty darn good for you in general, can you eat beans on a daily basis when you’re doing a low-carb diet? Well, technically yes, but it’s hard. “Incorporating beans into a low-carb, high-fat keto diet could be challenging,” Sheth explains. Why? Well, while you can have them, technically, they will take up a significant portion of your allowed carb intake on the diet.

Many meats contain additives, artificial ingredients, and unnecessary sugars so you’ll need to eliminate those to improve your health. They include processed and cured meats like pepperoni, salami, hot dogs, and certain jerky. For more information about protein on keto, check out Is Too Much Protein Bad for Ketosis? When following keto, you want to get the majority of your carbohydrates from vegetables such as leafy greens (which contain almost no carbs), asparagus, and broccoli, and most other vegetables that grow above ground. Avoid starchy vegetables like potatoes, corn, and parsnips. The rest of your carbohydrate intake should come from the carbs in nuts and seeds, the small amount in dairy and on occasion, from fruits like berries. Most vegetables, including leafy greens and cruciferous vegetables, are encouraged on keto. Cooking your vegetables helps break down the plant matter so their nutrients are easier for your body to absorb and use. On the other hand, you may be skipping veggies altogether if counting every baby carrot is getting too complicated. But it’s important to get in vegetables (these contain fiber that prevent constipation, a potential side effect of keto) while minding portions and properly counting carbs. Go for nonstarchy options in a rainbow of colors for a variety of nutrients, says Tucci, like leafy greens, cucumber, tomato, broccoli, cauliflower, bell peppers, and asparagus. When it seems as if the sole goal of keto is to drastically cut carbs, the rest can feel like an afterthought. “Reducing your carbohydrate intake is great, but focusing on higher-quality products when budget allows will help improve your health, too,” says Clevenger. That means choosing omega 3-rich foods, like wild salmon, grass-fed, local, or organic meats, and snacking on whole foods rather than processed keto-approved treats. It also means trying to follow a balanced diet as best you can by incorporating as many nutrient-rich fruits and veggies as you can. Many registered dietitians aren’t a fan of keto because it may lead to nutrient deficiencies. You can help avoid these by working with an RD yourself as you follow keto.|Why is the keto diet recommended for people with diabetes or prediabetes? Because the keto diet helps to reduce blood sugar and insulin levels, it is now being used for people with type 2 diabetes and for people with prediabetes to lower their hemoglobin A1C to a healthy level. Who else can benefit from this diet? Women with polycystic ovary syndrome who follow a low-glycemic-index diet - a variation of the keto diet that involves eating based on how foods affect your blood sugar level - have also seen positive results. Recent studies show the diet may treat the following alone or have compounding effects with other medical treatments: migraine headaches, brain tumor/cancer, Alzheimer’s, Parkinson’s disease, mitochondrial disease, Lou Gehrig’s disease (ALS), autism, and traumatic brain injury. Overall, more research is necessary. For the general population, is the keto diet healthy? While this diet has been shown to accelerate weight loss and to improve certain health conditions, it has its fair share of critics. Lack of nutrients such as B vitamins that are typically found in beans and grains can be of concern. Keep in mind those who follow a ketogenic diet are more likely to have other deficiencies because the variety of food they’re allowed to eat on this diet is so limited. When people on a ketogenic diet are consuming large quantities of non starchy vegetables, the excessive amounts of insoluble fiber also can lead to nutrient malabsorption. Although there are a few exceptions, non starchy vegetables aren’t rich sources of fermentable, prebiotic fiber. One of my favorite nutrients - fiber - is critical to serve as food for the gut bacteria and for the production of butyrate and other short-chain fatty acids, important for immune function, controlling inflammation, and overall gut health. The gut is essential to the brain and vice versa in terms of anxiety, depression, and pain management. The keto diet is missing a huge piece of this puzzle. Now onto fats, the ketogenic diet is seen as the “bacon and butter” diet, but it doesn’t have to be.|Eat foods that support your goals most of the time, allowing for some flexibility to enjoy life. If your diet is something you “cheat” on, it’s probably not a sustainable way of eating. Can you have fruit on keto? The problem with fruit is that it can be high in carbs, which makes it difficult to include on a typical keto diet. However, by choosing moderately sized servings of lower-carb fruits, it is possible to eat some fruit and stay in ketosis. See the best options here: Can I Eat Fruit On a Keto Diet? What is lazy keto? On a “strict keto” diet, you track protein, fat, and carb intake and aim to hit specific macros. In contrast, someone who says they’re doing “lazy keto” only tracks their carbohydrate intake to make sure it’s low enough to be ketogenic. Otherwise, they eat whatever they want. What is dirty keto? Dirty keto diets are very low-carb like any other keto diet, but otherwise, anything goes in terms of food quality. The keto diet boasts a ton of transformation stories-even celebs like Jenna Jameson, Al Roker, and Vanessa Hudgens have dabbled in it (and have the before-and-after photos to prove it). But um, it's still hard work-revamping your diet by almost totally cutting out carbs is a drastic change for your body (especially if you're a pizza and pasta lover), so there's got to be an easier way to get into ketosis (a.k.a., that state where your body burns fat for fuel instead of carbs), right? Maybe with special keto supplements? Hold on, keto supplements? Exogenous ketones or ketone salts (a.k.a. Together, these reportedly work to increase the amount of fat in your body and kick you into ketosis (a.k.a. McWhorter. Ketone supplements also allegedly block carbohydrates from being absorbed or metabolized, says McWhorter. Those claims are, well, just claims-"If you want to waste your money and potentially consume adulterated products with little or no research backing them, then sure, go right ahead and get those keto supplements," says McWhorter. And because there's such limited peer-reviewed research to support using them, they might even be harmful to your health in the long run, says Michelle Milgrim, RD, a nutritionist at Northwell Health in New Hyde Park, New York. But there haven't been any long-term studies looking at these outcomes over time, she adds. Side effects from keto supplements are also a red flag. Well, can keto supplements do anything at all? While keto-specific supplements, like exogenous ketones, do temporarily elevate the level of ketones in the blood, says Amanda Maucere, RD, a nutritionist at Lung Health Institute in Tampa, Florida, the overall impact on the body is not the same as getting there via your dietary choices. The internet is abuzz with anecdotes telling of the amazing benefits of a ketogenic (or “keto”) diet. Nothing new there, then, as every year is marked by the rise and fall of a new diet fad - most amplified by the social media echo-chamber but with little to commend them. This time, though, it caught my attention. Not just because I am a modestly overweight 52 year old whose love for food and drink is slightly stronger than my desire to be skinny, and as a result someone who has been on a diet every January for at least 20 years and now knows he needs he miracle. But because of the science behind it. For a start, I first began reading about ketogenic diets thanks to Ethan Weiss, M.D., a prominent UCSF cardiologist on Twitter, whose scientific acumen I respect. If he believes in the benefits of ketosis, then I should definitely look a little closer.
Just enter your info into our keto macro calculator. How much fiber do I need? There is some controversy around this. So, you might actually be fine eating less than the “official” recommendations. Start with 15-20 grams of fiber per day and add more a few grams at a time if needed, based on how you feel. Get as much fiber as possible from whole foods (vegetables, seeds, etc.) before you try a supplement. How to know if my macros are right? You’ll know if your macros are correct based on the results you see. As a few group members said, “measure, measure, measure” and take pictures. Don’t just rely on the scale. Sometimes you might see improvement in how your clothes fit or your body measurements before the scale catches up. If you don’t notice any results after a few weeks, first make sure you are actually in ketosis and not getting carbs sneaking in. If you are, take a look at that fat lever and see if you can nudge that down. The regimen kicks the body into a natural fat-burning mode called ketosis by starving a person's system of carbs and sugars, which are typically the first fuels we burn. Some people say that being in ketosis helps them focus and decreases their appetite, while trimming belly fat. But more research is needed on the long-term effects of the high-fat diet, and anyone who wants to go keto should consult their physician first. Dieters from Silicon Valley to the Hollywood hills are convinced that the keto diet is a miracle for the body. The high-fat regimen has become the go-to eating plan for celebrities like Halle Berry and the Kardashians, Silicon Valley tech workers, venture capitalists, and sports stars like LeBron James. Fans of the diet believe it can help burn belly fat, tamp down on hunger, and increase energy, all while encouraging consumption of fatty and oily foods. The keto diet is designed to get the body into a natural fat-burning state called ketosis.|But before you order a beer at the bar hosting your Wednesday night pool league, you need to consider why you’re on the keto diet in the first place. Most people use the targeted keto diet to enhance their athleticism and recovery. Alcohol won’t help with this at all. 11. Will the Targeted Keto Diet Actually Make Me a Better Athlete? A lot of research indicates that being in a fasted state makes incredible feats of athleticism easier. Take, for instance, marathoners. They “hit a wall,” because they run out of stored glycogen and they’re not fat-adapted. Many of the world’s most successful marathoners find it easier to be fat-adapted than to consume carbs on their 26.2-mile run. 12. What Are the Primary Benefits of a Keto Diet? Regardless of the type of keto diet you choose to follow, there are some pretty significant benefits. 13. Following a strict diet for weight loss and then quickly reverting to old habits when the dietary changes are too restrictive can lead to what is known as weight cycling, or yo-yo dieting. Gaining and losing the same weight over and over can start to have a negative impact on your self-image and motivation, and potentially your health. For athletes, research on the keto diet highlights potential improvements in athletic performance, especially when it comes to endurance activities. An article suggests ketogenic-type diets may allow endurance athletes to rely mostly on stored fat for energy during exercise rather than having to refuel with simple carbohydrates during endurance training and competition while additionally improving recovery times. If you’re looking to lose weight, one benefit the ketogenic diet may offer is the ability to suppress appetite. A review of this form of eating suggests it may help decrease appetite, but how this actually happens needs to be studied further. When it comes to weight loss - a big possible draw of the plan for many individuals - the benefits of the ketogenic diet may not be much different from any other diet plan. “There is no magical weight loss benefit that can be achieved from this diet,” says Spano. For individuals with diabetes, adapting a very low-carbohydrate diet, such as the ketogenic diet, may offer some benefits when it comes to glucose management. For instance, a review found that dietary restriction of carbohydrate may reduce or eliminate the need for medication in individuals with type 2 diabetes.
So if your goal is weight loss, eat enough fat to be satisfied, but there’s no need to “get your fats in” once you’re satisfied. Drink lots of water. This is especially crucial on a low carb or keto diet. Why? When you eat carbohydrates, your body stores the extra as glycogen in the liver, where they are bound to water molecules. Eating low carb depletes this glycogen, which allows you to burn fat - but it also means you are storing less water, making it easier to get dehydrated. Instead of the traditional recommendation of 8 cups of water per day, aim for 16 cups when following a low carb lifestyle. Keep up electrolytes. The major electrolytes in our bodies are sodium, potassium and magnesium. Because a low carb diet (especially a keto diet!) reduces the amount of water you store, this can flush out electrolytes and make you feel sick (called “keto flu”). This is temporary, but you can avoid or eliminate it by salting your food liberally, drinking broth (especially bone broth), and eating pickled vegetables. This is in contrast to a glycolytic state, where blood glucose (sugar) provides most of the body’s fuel (or energy). This state can also be achieved by multiple days of total fasting, but that isn’t sustainable beyond a few days. ’s also your body’s second preferred source of energy when carbohydrates are not easily accessible. How Do You Get Into Ketosis? So many people ask, does the keto diet work? Yes, of course, but only if you can get your body into ketosis. 1. Consumption of glucose from carbohydrate foods - grains, starchy vegetables, fruit, etc. - is cut way down. 2. This forces your body to find an alternative fuel source: fat (think avocados, coconut oil, salmon). 3. Meanwhile, in the absence of glucose, the body also starts to burn fat and produces ketones instead. 4. Once ketone levels in the blood rise to a certain point, you enter into a state of ketosis. 5. This state of high ketone levels results in quick and consistent weight loss until you reach a healthy, stable body weight. The classic keto macros have been 75% fat, 5 % carbs and 25% protein. Many people have seen weight loss using this macro amount. But there are just as many people who have tried this classic keto approach, eating a lot of dietary fat and NOT seeing weight loss like others. I was one of those people who in 2015 tried eating all the fat and thought I’d lose weight just like I saw so many other people losing weight. It didn’t work for me and I wondered what I was doing wrong. I decided to go very strict keto in 2018 and you can read about my 6 week results here. I did lose some body fat, but not nearly has much as I had hoped for being strict keto for 6 weeks. I knew something had to change if I wanted to see the weight and fat loss I desired. What Foods Are Off-Limits on a Keto Diet? What Can You Eat on a Keto Diet? So…what can you eat on the keto diet? The answer is: Plenty. See this comprehensive list of keto foods! The easiest way to get started on a keto diet is to stock your kitchen with keto-friendly foods, and get rid of any foods that may tempt you into deviating from your keto meal plan. If you’re looking for keto recipes, we’ve got you covered. Dishes like slow cooker beef bone broth and keto pizza can fit into just about anyone’s meal plans. If you’ve recently adopted the keto diet, you may be feeling a variety of side effects including nausea, dizziness, constipation, headaches and irritability. This is your body’s natural reaction to removing carbs from your diet, and we promise the symptoms are temporary. Also known as keto flu, it’s a natural reaction that occurs when your body switches from burning glucose as energy to burning fat. Is Following the Ketogenic Diet Dangerous? Ketoacidosis happens when your body fails to produce enough insulin. On the other hand, when done properly, nutritional ketosis can improve insulin function.
Storing glycogen requires water, and once our glycogen stores are depleted (which happens during ketosis), rapid loss of “water weight” can occur. Once you refill the carb deficit, that weight may quickly come back. And as if all that’s not enough, the ketogenic diet can damage your relationship with food. Dieters often only consider the nutritive components of certain diets, while ignoring that food was not only made for energy. Food is rooted in tradition, joy, and satisfaction, and restriction leaves some people with psychological damage. Restriction often leads to an unhealthy preoccupation with food, anxiety around eating, interference with social events and mealtimes, and an increased risk for eating disorders. Overall, there is still a lot of research to be done on the effects of the keto diet. It’s important to be very thorough in researching your eating plan before adhering to something that calls for such extreme measures. A better option? Find an eating style that is sustainable, enjoyable and nourishing. It is possible to find a balance between all of the noise we constantly hear about food. A great way to start would be to try to get in tune with what foods your body is craving and why you might be craving them. Weight is a determinant of health, but it’s not the only one. Our advice is to focus on incorporating wholesome, healthy food while also acknowledging that an indulgent treat is part of life. It’s time we stop adhering to these rigorous rules of diets and begin to develop our intuitive eating skills so we can respect our body and all it does for us, not just judge it for its size. One concern voiced in some studies is loss of muscle tissue beyond what might be expected from any calorie-restricted weight loss diet, possibly because the body is attempting to break down protein to create glucose, but Volek says this isn't an issue when the ketogenic diet is followed correctly. Could the ketogenic diet's extreme restriction of carbohydrates contribute to micronutrient deficiencies and impact gut health? Ketogenic diets don't just eliminate sugar and refined carbohydrates; they also curtail pulses, whole grains, fruit, and starchy vegetables. All of these foods contribute vitamins, minerals, antioxidants, phytochemicals, and fiber-including prebiotic fiber that promotes a healthy gut microbiota. Numerous studies have demonstrated that the ketogenic diet alters the gut microbiota in ways that have benefit for reduction of epileptic seizures,15 but research is lacking on the impact in populations using the diet for weight loss or diabetes management. Somerville, Massachusetts-based Jessi Haggerty, RDN. She also points out that when people on a ketogenic diet are consuming large quantities of nonstarchy vegetables, the excessive amounts of insoluble fiber also can lead to nutrient malabsorption.
Here are answers to some of the most common questions about the ketogenic diet. 1. Can I ever eat carbs again? Yes. However, it’s important to significantly reduce your carb intake initially. After the first 2 to 3 months, you can eat carbs on special occasions - just return to the diet immediately after. 2. Will I lose muscle? There’s a risk of losing some muscle on any diet. Yes, but it may not work as well as on a moderate carb diet (52, 53). For more details about low carb or keto diets and exercise performance, read this article. 4. How much protein can I eat? Protein should be moderate, as a very high intake can spike insulin levels and lower ketones. Around 35% of total calorie intake is probably the upper limit. 5. What if I am constantly tired, weak, or fatigued? You may not be in full ketosis or be utilizing fats and ketones efficiently. To counter this, lower your carb intake and revisit the points above. 6. My urine smells fruity. 7. My breath smells. What can I do? This is a common side effect. Try drinking naturally flavored water or chewing sugar-free gum. 8. I heard ketosis was extremely dangerous. People often confuse ketosis with ketoacidosis. Ketoacidosis is dangerous, but the ketosis on a ketogenic diet is usually fine for healthy people. Speak to your doctor before starting any new diet. 9. I have digestion issues and diarrhea. What can I do? This common side effect usually passes after 3 to 4 weeks. Tracking your macros and net carbs can be tricky, so I advise you download a keto app that includes a keto diet calculator. It will help keep you on track. A popular keto supplement are exogenous ketones (popularly called “keto diet pills”) that may help you achieve results earlier as well as remain in that state. Also, consider supplementing with the amino acid leucine, as it can be broken down directly into acetyl-CoA, making it one of the most important ketogenic amino acids in the body. While most other amino acids are converted into glucose, the acetyl-CoA formed from leucine can be used to make ketone bodies. It’s also present in keto friendly foods like eggs and cottage cheese. It’s important to also drink lots of water, the most important of all keto drinks. Getting enough water helps keep you from feeling fatigued, is important for digestion and aids in hunger suppression. While fat reigns supreme on the diet, don’t just turn to bacon, cheese, and cream. When choosing your fats, aim to include more anti-inflammatory omega-3s, particularly EPA and DHA, the type that are found in salmon, sardines, oysters, herring, and mussels, says Clevenger. Other healthy fats are a good choice, too; if you haven’t stocked up on avocado, olive oil, and seeds such as chia seeds and flaxseed, definitely do. They’re not only keto friendly - they also offer healthy polyunsaturated and monounsaturated fat that your body needs to perform at its best. With people consuming more sodium than ever in a diet rich in processed food, you’re probably not used to hearing the call to eat more salt. But on keto, it’s necessary. Not only does the clearance of ketones cause the body to lose sodium, but you may be getting much less table salt (which is comprised of 40 percent sodium and 60 percent chloride) now that you’ve kicked out the top source of salt in the standard American diet: packaged, processed foods, including bread, chips, crackers, and cookies. Click here to grab my new phone number! What can I eat on a keto diet? Changing up your food lifestyle can seem overwhelming. Cutting out certain fruits and vegetables and replacing them with fat-filled foods like bacon, cream, and ribeye steaks can get a little confusing as well. To help get you started, I’ve put together a ketogenic diet food list just for you! You can download the full keto foods list HERE or view it below. Watch for meats with added high-carb fillers like hot dogs, sausage, meatballs, and cold cuts. Most shellfish is fine for keto but watch for higher carb counts in clams and mussels. Always avoid breaded fish and seafood that is pre-made due to possible high carb content. When in doubt, check the food label if buying in store. You can also eat the eggs that come from these animals in any prepared fashion, such as hard-boiled, fried, scrambled, poached, or omelet. Given all the buzz, adopting a ketogenic diet may be the perfect weight loss plan, especially if you have diabetes, or want to try this approach to lose those troublesome extra pounds. After all, it’s a very low-carb meal plan that promises effective weight loss while also lowering your blood sugar to the point where you could possibly stop taking medication. By all accounts, the “keto” diet, as it’s widely known, may even reverse type 2 diabetes, at least for some lucky individuals. Another advantage to the keto diet: It can help reduce systemic inflammation, which can have a variety of negative effects on your entire body. You can create meals that are appealing and delicious when following a keto diet. Unlike some of the other popular low-carb diets, which typically are high in animal protein, the keto diet focuses on getting to the body to burn stored body fat instead of sugar as the main fuel. When body fat is broken down in the liver instead of glucose, s an energy byproduct known as ketones are produced. The average person doesn’t fully understand what ketosis really means, or that it’s necessary to measure blood levels of ketones. The mere presence of a few ketones doesn’t make one in ketosis. And peeing on a stick isn’t the way to measure blood levels of ketones, because simply spilling a few ketones in urine isn’t indicative of ketosis. After all, we all produce ketones after a certain period of not eating. That doesn’t mean that our body is magically shifting gears and the ketones are changing how we’re oxidizing all the food in our bodies. The ketogenic diet’s extreme restriction of carbohydrates contributes to micronutrient deficiencies and impacts gut health. Ketogenic diets don’t just eliminate sugar and refined carbohydrates; they also cut out pulses, whole grains, fruit, and starchy vegetables. All of these foods contribute vitamins, minerals, antioxidants, phytochemicals, and fiber which include prebiotic fiber that promotes a healthy gut microbiota.|“I don’t recommend staying on the keto diet permanently. It can be really restrictive,” says Mancinelli. Long-term research on the keto diet is limited, so there’s no telling for sure what cutting out certain major food groups and cutting carbs will eventually do to your body. Registered dietitians warn that nutrient deficiencies may be possible if you’re on it for too long. Stick to the keto diet for three to six months max, says Mancinelli, noting that some people opt to cycle in and out of the diet throughout the year. Because it’s not a forever diet, there will be life after keto. But even when you go off it, you can expect that your taste preferences will have changed. “You likely won’t want as many carbs, and things will taste extremely sweet,” she says. That’s good, because the last thing you want to do is go back to your old eating habits and regain weight that you lost. While everyone’s nutrition requirements differ, generally, you may eat 40 to 45 percent fat and stick to 120 to 150 g of carbs per day to help you keep the weight off, she says. That said, the US News report noted that the long-term weight loss effects of keto aren’t clear.
Keto is a diet that was developed decades ago and originally used for patients with severe epilepsy, some of whom were on the diet for life with no evidence of harm. It consists of low carb, high fat and only moderate protein intake, as opposed to the Atkins diet. Keto isn’t as meat-heavy as commonly believed. Hwu relies on certain “go to” foods like full-fat regular cream cheese, sour cream and avocados as staples. He also consumes a lot of green vegetables and cauliflower. Since starting the keto diet, Hwu has dropped 25 pounds and has maintained the weight loss. His blood pressure, triglycerides and sugar levels have all decreased, which are healthy signs. His biomarkers, including lipid profile and blood pressure have been excellent, he said. There have been a number of studies that show the connection between obesity and certain cancers. Hwu feels that keto makes sense because his patients are not hungry on it, it manages their weight and blood sugar levels and keeps insulin and IGF-1 levels low - two proteins that have been shown to drive some cancers. “I feel that fat intake has been overly emphasized as a negative factor and that a high intake of carbs and the subsequent spikes in insulin and IGF-1 (an insulin-like hormone in the blood) that they cause are more harmful to health overall,” Hwu said. Hwu’s colleague, Dr. Jennifer McQuade, an assistant professor and physician scientist in Melanoma Medical Oncology at MD Anderson says they are currently conducting both human and animal studies of the effects of diet, including the ketogenic diet, on cancer. In addition, they are testing a plant-based high-fiber diet aimed at the gut microbiome, which has been shown to impact response to immunotherapy, a type of cancer treatment that utilizes the patient’s own immune system to fight the disease. They expect results from the studies early next year. What Foods Are Off-Limits on a Keto Diet? What Can You Eat on a Keto Diet? So…what can you eat on the keto diet? The answer is: Plenty.

You know the feeling you get after having a big bowl of pasta for lunch? Your blood sugar levels crash after processing all those carbs, and the rest of the day becomes naptime. That’s not the case on the keto diet. In metabolic fat-burning mode, your body can tap into fat stores for energy. Ketosis also helps the brain create more mitochondria, the power generators in your cells. More energy in your cells means more energy to get stuff done. Ketones suppress ghrelin, your hunger hormone. They also increase cholecystokinin (CCK), which makes you feel full. Reduced appetite means it’s easier to go for longer periods without eating, which encourages your body to dip into its fat stores for energy. Fat is a satiating macronutrient, which means it helps you feel fuller, longer. On a high-fat diet, you’ll spend less time snacking and more time tackling your to-do list. Related: Learn how Bulletproof MCT Oil helps satisfy hunger. The ketogenic diet can be dizzyingly complicated. You want to load up on fats and protein, and keep your carb intake low-but all fats and proteins aren’t alike, and there are some veggies higher in carbohydrates than others. Oh, and fruit is pretty much banned. But don’t worry: We’ve put together the best and worst of each category so you can go keto with confidence. Saturated fats including coconut oil, ghee, grass-fed butter, duck fat, tallow, and lard-all essential for a healthy immune system, dense bones, and proper testosterone levels. Monounsaturated fats like olive, avocado, macadamia, and almond oils, which boost heart health and provide vitamin E-important for vision and a strong immune system. Polyunsaturated omega-3s such as wild-caught salmon, sardines, and sustainably harvested seafood-to prevent heart disease and stroke and reduce blood pressure. Medium-chain triglycerides, fatty acids that are easily absorbed and used for energy. Linked to weight loss, MCTs increase satiety and rev-up metabolism. Refined fats and oils like sunflower, canola, soybean, grapeseed, and corn oils, which have been processed at high temperatures, creating free radicals that can damage cells. Then you’ll want to take an occasional ketosis holiday, adding a serving of unprocessed, whole grains to allow your body to chance to work less hard. Staying in ketosis long-term-without breaks- can cause muscle aches, nausea, and fatigue. Adhering to the keto diet puts your body into a state of ketosis, which sounds similar to ketoacidosis. However, don’t confuse these terms as ketosis and ketoacidosis are two very different physiological states, Dr. Goss explains. “Ketosis is a normal physiological response that occurs when you eat a high fat, low carb diet, while ketoacidosis is more pathological,” she says. “It happens in people with diabetes whose blood glucose is very high (hyperglycemia). When in ketosis, the body begins to burn stored fats for energy, and this results in the build-up of acids, known as ketones, in your blood. A person following the keto diet aims to burn unwanted fat by actually pushing the body to rely on fat, not carbohydrates, for energy.|“What concerns me is when people say they’re following a keto diet but not all the way or something along those lines. This could lead to weight gain and increased blood lipid values if someone just starts eating a high-fat diet and borrowing concepts from ketosis.” For example, a small, preliminary study published in February 2019 issue of Nutrients suggested those who take a "cheat day" on keto could be harming their blood vessels. How It Works Think of Mediterranean keto as a combination of two popular approaches to eating: sticking to standard keto macro amounts, while emphasizing Mediterranean diet elements like fatty fish and olive oil. The main emphasis is on the quality of fats you’ll be eating, says Madeline McDonough, RDN, who is based in Boston. “Unlike the standard keto diet, which doesn’t specify which fats to prioritize, Mediterranean keto diets emphasize options like monounsaturated fatty acids, which may help lower LDL cholesterol, and omega-3s that are anti-inflammatory,” she says. Alcohol: Alcoholic beverages are high in carbs, which can take your body out of ketosis. Sugar-free diet foods: These products can be high in sugar alcohols, which affect ketone levels. They’re highly processed, too. FDA authorized at home saliva self-collection testing kit for COVID-19. No waiting in line or uncomfortable swabs. Butter and cream: Products of grass-fed animals, if possible. Healthy oils: Mainly extra virgin olive oil, but coconut and avocado oil are ok, too.

Because dietary carbohydrate is extremely limited on the keto diet, the body cannot rely very much on carbohydrate as a fuel source for energy. This triggers a metabolic state called ketosis - a response by the liver to produce ketones, which are made from fatty acids. The ketones travel through the blood where they are used as a primary fuel source by the central nervous system (brain and spinal cord) and used to a lesser extent as fuel by other tissues. Ketosis will also result in the body’s use of protein (e.g. muscle) as fuel to some extent. The Ketogenic Diet has exploded in popularity recently because it does cause rapid, and sometimes dramatic weight loss. It’s not unusual for people to lose 8-12 pounds during the first couple of weeks.
While fat reigns supreme on the diet, don’t just turn to bacon, cheese, and cream.

Not only does the clearance of ketones cause the body to lose sodium, but you may be getting much less table salt (which is comprised of 40 percent sodium and 60 percent chloride) now that you’ve kicked out the top source of salt in the standard American diet: packaged, processed foods, including bread, chips, crackers, and cookies. You can learn more here. On keto you can eat fat, protein, and to a certain extent vegetables, nuts, and low-carb sweeteners. Fats like butter, olive oil, coconut oil, and bacon grease add flavor and help you feel full on keto meals. Meat, cheese, and eggs provide protein and vitamins and minerals, and essential fatty acids on a ketogenic diet. These all are nearly no-carbohydrate foods, and will make up most of your meals. Steak, burgers, deviled eggs, baked chicken (with the skin!), meatballs, and more. Vegetables should be included as desired, in general green vegetables are lower in carbohydrate than other veggies. Carb counts should be tracked with your vegetables. Nuts can be included, but should be carefully measured and limited especially if you are doing keto for weight loss. Nuts are delicious, and can be used to make low-carbohydrate baked goods, but also are packed with calories and contain some carbohydrates. Not everyone will feel best eating high fat and many will not lose their body fat eating that much on a daily basis. Your activity level, lifestyle, age, and genetics, are all factors in what will help you achieve weight loss. We are all bio-individual and have different needs in regards to daily macros. But one thing remains the same, for a well-balanced, ketogenic diet that promotes health and fat loss, eating whole, single ingredient, nutrient dense foods is the best way to achieve your health goals. Packaged, processed and refined so-called “keto” foods are not the best way to achieve success on a ketogenic diet if your searching for the long term health benefits. If you’re over 40 like me, have any kind of health issues, like hypothyroidism, like me, then the classic ketogenic macros might not work for you. I tried unsuccessfully to make those high fat macros work for me for a whole year without any weight loss back in 2015. Through these years of trials and errors, numerous testing, bio-hacking, and learning what works best for my own body to lose body fat, I can confidently say, you can and should adjust your fat intake to discover the right amount for you to achieve your weight loss goals.|Although they are distinct, paleo and keto diets share many characteristics. Below are some of the main ideas these diets have in common. Fundamentally, both paleo and keto diet plans are intended to rely on whole-food sources of nutrients. A whole food is a food that has undergone a minimal amount of processing by the time it gets to your plate. Both keto and paleo diets strongly encourage eliminating all ultra-processed foods and replacing them with whole foods like fresh vegetables, meat, fish and nuts. Though for different reasons, both paleo and keto diets strongly discourage eating grains and legumes. For the paleo crowd, this elimination is largely based on the fact that grains and legumes were not likely part of early human diets and they contain antinutrients. Antinutrients are compounds, such as lectins and phytates, that can be found in some plant-based foods. The keto diet also eliminates grains and most legumes, but this is because of their carbohydrate content. “We know that these endothelial microparticles are elevated in conditions such as heart disease and type 2 diabetes, which is why we were interested in measuring them,” he explains. Besides the potential for blood vessel inflammation, Little also cautions that the metabolic adaptations your body experiences on the keto diet means that you’re relatively glucose intolerant, so a meal (or day) of high carb eating might not be the best plan. “When you adapt to a ketogenic diet, you become a proficient fat burner and this occurs at the expense of carbohydrate metabolism. It probably isn’t the best thing for your metabolism to throw carbohydrates (especially high glycemic index carbs in high amounts - such as a glucose tolerance test drink that we used or a big 'cheat meal') into the mix if you are on a ketogenic diet,” he says. Devine agrees and shares concerns about the long-term risks of this approach. “The benefits from a ketogenic diet are a one-way street,” she says. It's advertised as a weight-loss wonder, but this eating plan is actually a medical diet that comes with serious risks. In the world of weight-loss diets, low-carbohydrate, high-protein eating plans often grab attention. The Paleo, South Beach, and Atkins diets all fit into that category. They are sometimes referred to as ketogenic or "keto" diets. But a true ketogenic diet is different. Unlike other low-carb diets, which focus on protein, a keto plan centers on fat, which supplies as much as 90% of daily calories. And it's not the type of diet to try as an experiment. Kathy McManus, director of the Department of Nutrition at Harvard-affiliated Brigham and Women's Hospital. How does the keto diet work? Here are the basics of keto: The diet aims to force your body into using a different type of fuel. Instead of relying on sugar (glucose) that comes from carbohydrates (such as grains, legumes, vegetables, and fruits), the keto diet relies on ketone bodies, a type of fuel that the liver produces from stored fat. The ketogenic diet was originally created to treat neurological diseases like epilepsy. Over the last century, countless studies have been performed to examine the other health benefits of ketogenic diets. Heart disease: The ketogenic diet can improve cholesterol levels and reduce body fat and blood sugar-all risk factors for heart disease. Cancer: Keto is currently being used to treat cancers and slow the growth of tumors. Alzheimer’s disease: Keto may reduce the symptoms of Alzheimer’s disease or slow its advancement. Epilepsy: Research has indicated that the ketogenic diet can cause a sizeable reduction in the number of seizures experienced by epileptic children. Parkinson’s disease: One study produced evidence that the diet helped improve Parkinson’s disease symptoms, though more research is needed. Polycystic ovary syndrome: Keto can lower insulin levels, which may play a role in treating polycystic ovary syndrome. Brain injuries: One study conducted on animals found that keto can aid in concussion recovery and post-brain injury recovery.|It takes about three weeks of carbohydrate elimination for your body to transition into ketosis. Here are the pros and cons of the keto diet. “There has been anecdotal evidence of people losing weight on the ketogenic diet,” says Melinda R. Ring, MD, director of Northwestern Medicine Osher Center for Integrative Medicine. Gomez says people feel less hungry because fatty foods take a longer time to break down in the body. Weight loss not only comes from ketosis, but also from reducing calorie intake by eliminating food groups. On paper, burning fats by eating more of them is enticing, which is why the diet has become popular. The keto diet allows many people to eat the types of high-fat foods that they enjoy, such as red meats, fatty fish, nuts, cheese and butter, while still losing weight. The keto diet helps reduce seizures in pediatric patients with epilepsy. Endurance athletes and body builders also use it to scrap fat in short timeframes. The classic keto macros have been 75% fat, 5 % carbs and 25% protein. Many people have seen weight loss using this macro amount. But there are just as many people who have tried this classic keto approach, eating a lot of dietary fat and NOT seeing weight loss like others. I was one of those people who in 2015 tried eating all the fat and thought I’d lose weight just like I saw so many other people losing weight. It didn’t work for me and I wondered what I was doing wrong. I decided to go very strict keto in 2018 and you can read about my 6 week results here. I did lose some body fat, but not nearly has much as I had hoped for being strict keto for 6 weeks. I knew something had to change if I wanted to see the weight and fat loss I desired.

Snacking-wise, nuts are a good source protein and fat, so they can be eaten more, as well as cottage cheese and Greek yogurt. Mainly the plain variety, though, as reduced sugar intake is essential for the success of ketogenic diet. What are the main benefits of keto diet? As well as these, keto can reduce acne and it might also improve heart health and protect brain functioning, although these benefits have not been proven by rigorous lab tests yet, so we can't say for sure that is a benefit. Is keto diet safe? Either way, before you start buying crates of avocados, and especially if you have issues with obesity, you should consult a medical professional and get their advice and guidance. Everyone's needs are different and what works for the vast majority of people might not work for you personally. Be safe and sensible, and always ask for help if unsure.
While it might seem tough to limit carbohydrate intake this strictly, there's one important loophole to keep in mind. Because some carbs come from dietary fiber, which the body doesn’t break down and absorb, keto dieters can subtract those from their daily count. The resulting number is called net carbs, and it's a better measure of how many carbohydrates you're ingesting. For example, while a carrot may have 6 grams of carbs, about 1.7 of them are dietary fiber, so the net carb intake from the carrot is just over 4 grams. Similarly, more than 75% of the carbs in spinach are fiber, making it a relatively safe choice for keto-ers. Kirkpatrick suggests dieters limit their net carb intake to 25 grams a day. Like any restrictive diet, it’s hard to get a balanced plate of all the vitamins and minerals your body needs to stay healthy on a keto plan. The diet is also not recommended for pregnant women, people with liver and kidney problems, or anyone prone to gout . Ketones are responsible for a lot of the keto benefits you might have heard about, like fewer cravings, more brain power and lasting energy. The keto diet is one way to get your body to make ketones. Your body can also produce ketones when you’re intermittent fasting or taking keto supplements like Bulletproof Brain Octane C8 MCT Oil, aka the most ketogenic MCT oil. Ketosis delivers a bunch of health benefits besides just burning fat. Your metabolism works differently on keto, and people report the following changes in their mind and body. More than 60% of your brain is fat, so it needs a steady supply of fat to keep the engine humming. The quality fats you eat on a ketogenic diet do more than feed your day-to-day activities-they also feed your brain. When your body uses ketones for fuel, you won’t experience the same energy crashes or brain fog as you do when you’re eating a lot of carbs. What can I drink? Which slimming club is best? Which artificial sweetener should I choose? What is the ketogenic diet? A ketogenic diet is a very low-carb diet, considered to be when you eat a level of carbohydrate of around 30g of carbohydrates per day or below. This encourages the body to get its energy from burning body fat which produces an energy source known as ketones. Note that it is important that you speak to your doctor if you are considering following the diet as precautions may need to be taken before starting. People on insulin will typically require smaller doses of insulin which leads to less risk of large dosing errors. The diet helps burn body fat and therefore has particular advantages for those looking to lose weight, including people with prediabetes or those otherwise at risk of type 2 diabetes. Based on the understanding that carbohydrate is the macronutrient that raises blood glucose the most, the primary goal of a ketogenic diet is to keep consumption lower than that of a traditional low carbohydrate diet with moderate protein and a very high fat content. The keto diet is made up of mostly fats, moderate protein and a small amount of carbs. Eating a lot of fat and very few carbs puts you in ketosis, a metabolic state where your body burns fat instead of carbs for fuel. There are different types of keto diets, including the standard diet, cyclical keto and dirty keto. Get the details on the benefits of keto and how to start the keto diet below. Eat fat to burn fat? It sounds counterintuitive, but that’s what makes the ketogenic diet so unique. Also called the keto diet, this high-fat, low-carb style of eating can help you feel energized and laser-sharp. It can even help you stay at a healthy weight-all while enjoying delicious, satisfying foods. Read on to learn everything you want to know about this style of eating with our keto diet for beginners guide. We’ll cover the science behind how it works, detail the amazing benefits of the keto diet and offer tweaks that can help you manage keto side effects and stay in a state of ketosis. If you feel more focused than you have in years, you may be in ketosis. You may be in ketosis if you can think more clearly, recall information better and feel more energized than you can ever remember feeling. But the only way to know for sure if you are in ketosis is to test the levels of ketones and sugar in your blood, breath, or urine. 6. Are There Other Types of Keto Diets? There are actually four types of keto diets. Specifically, people seeking a keto lifestyle can choose from the high-protein keto diet (HPKD), the cyclical keto diet (CKD), the targeted ketogenic diet (TKD) and the “standard” keto diet (SKD). 7. What Can I Eat on the High-Protein Keto Diet? On the high-protein keto diet, you have an allowed macronutrient ratio of 60% to 65% fat, 30% protein, and 5% to 10% carbs. Assuming you need 1,635 calories per day, you may get 480 calories from protein, 80 calories from carbohydrates, and 1,075 calories from fat. But whether runners, specifically, should put their bodies in a state of ketosis depends on your goals. One study of five endurance athletes, published in the Journal of the International Society of Sports Nutrition, showed that a 10-week keto diet improved the athletes’ body composition and well-being but not their performance. In fact, the athletes initially experienced reduced energy levels and an inability to undertake high-intensity bouts of exercise. Another recent study in the journal Medicine & Science in Sports & Exercise looked at the effects of the keto diet on exercise efficiency in eight trained athletes. After following the diet, the athletes saw a decline in running speed and power-running speed at VO2max declined by 5 percent. However, both studies were small, and experts acknowledge more research is needed to study keto’s full, long-term effects. “There isn’t really a lot of good research that shows those people can perform better, and that’s really what runners care about,” Kasparek says.
The primary fuel source for this system is creatine phosphate, which your body naturally produces, and which you can increase stores by taking creatine supplements. 20-50% of your body's resting metabolic needs. The glycolytic system uses glucose (a form of carbohydrate) to make ATP. The glucose used in glycolysis can have two fates. First, it can get turned into lactate and exported out of your muscle cells and into your blood. It can also continue into the oxidative system by turning into a molecule called acetyl-CoA and then going through the Kreb's Cycle. Lastly, we have the oxidative system. This system can utilize carbohydrates (as discussed above), fatty acids, or protein to produce energy. It does so by the body converting them into acetyl-CoA first. Your body makes energy in three ways. One way, the oxidative system, utilizes a molecule called acetyl-CoA to do a lot of the work. That is the "starter" to oxidative metabolism. When your body starts relying very heavily on oxidative metabolism, you start producing a lot of acetyl-CoA. If you’re trying out the keto diet you should take care to avoid sugary, starchy foods. Remember- carbohydrates should make up less than 5% of your entire calorie intake. Aim to have an absolute maximum of 50 grams of net carbs a day, but aim for 20 grams or less. Are there any ketogenic diet side effects? Immediately after starting the diet during the first week, some dieters may experience what is referred to as the “keto flu“. The keto flu is a term colloquially used to describe the general feelings of malaise some dieters feel at the beginning of the low-carb high-fat diet. Keto flu can be prevented or helped by focusing on getting plenty of sleep, increasing electrolyte intake, and reducing consumption of dehydrating drinks like caffeine and alcohol. But fear not! Starting out with keto has some positive benefits, too. During the initial adjustment phase most dieters report rapid weight loss - losing up to 10 lbs of body weight in 2 weeks or less. Aside from being an energy source, ketones are also important neural signaling molecules and gene transcription facilitators. Ketones also seem to modulate the stress response in neurons and make them more resilient to excitatory nerve transmissions-the kind that can cause seizures. D’Agostino also found that ketones can elevate levels of the calming neurotransmitter GABA. Theories aside, when he treated SEALs with a keto diet, their seizures stopped. But brain diseases aren’t the only illnesses doctors are beginning to think are metabolic rather than purely genetic in origin. Many common types of cancer- esophageal, pancreatic, colon, kidney, thyroid-are associated with obesity and diabetes, and D’Agostino believes he’s on the path to understanding why. Cancer cells thrive in high-sugar environments because they rely on glycogen (sugar burned for energy) to survive; type-2 diabetes, especially, provides potential cancer cells with a high-sugar environment. This suggests not only that glycogen may contribute to cancer, but also that it may be cancer’s Achilles’ heel: If cancer cells become compromised when their host is in a ketogenic state, the body’s own immune responses may be able to effectively fight the disease.|Claims of benefits of the ketogenic diet for cancer, dementia, and Parkinson disease are not scientifically substantiated. Do Ketogenic Diets Improve Health? Ketogenic diets result in weight loss for those who successfully use this strategy to reduce overall caloric intake by limiting all carbohydrate-rich foods like breads, pasta, rice, cakes, cookies, and colas. Most fruits, legumes, and whole grains are also essentially off limit. Currently, long-term data on keto diets and cardiovascular, cancer, and other chronic disease risks are lacking, and low-carbohydrate diets have been linked to increased mortality. Who May Benefit From a Ketogenic Diet? Individuals wishing to lose weight using a very structured approach may benefit from a keto diet. For patients with prediabetes or type 2 diabetes, limiting carbohydrates to 5% of calories can help control blood glucose if it contributes to weight loss and weight maintenance. It is common to experience fatigue during exercise, poor mental energy, increased hunger, sleep disturbance, muscle cramps, constipation, nausea, and stomach discomfort. Over the long term, a diet in which only 5% of total calories come from carbohydrates makes it impossible to obtain optimum amounts of antioxidant phytonutrients from fruits and vegetables. In the first 2 weeks of the diet, there may be significant increases in urine production and fluid shifts that may require adjustment of medications for hypertension, heart failure, and diabetes. It is important to consult with a physician before trying a ketogenic diet. You should change your diet only under the supervision of a physician and a registered dietitian. Conflict of Interest Disclosures: Dr Heber reported receiving personal fees from Herbalife Nutrition. No other disclosures were reported. Source: Abbasi J. Interest in the ketogenic diet grows for weight loss and type 2 diabetes. There are different variations of low carb, and the keto diet is a special type of low carb with added characteristics. Some people opt to count carbs diligently and some choose to simply focus on eat low carb/keto foods. What are net carbs? Net carbs is simply total carbs minus fiber and non-digestible sweeteners, like erythritol and allulose. We don’t have to count fiber and certain sweeteners in net carbs, because they either don’t get broken down by our bodies, are not absorbed, or are absorbed but not metabolized. Some people on a keto or low carb diet choose to count total carbs instead of net carbs. This makes it more difficult to fit in more leafy greens and low carb vegetables (which are filled with fiber), so you should only try that if you don’t get results with a net carb method. And, start with reducing sweeteners and low carb treats before deciding to do a “total carbs” method. She notes that ketosis may result in bad breath, dizziness, constipation, and low energy levels (commonly called the “keto flu”) for the first few weeks. More concerning, drastic weight changes, from keto or otherwise, can increase your risk of mortality, says Kizer. Weight cycling, also called yo-yo dieting, may put particular strain on the heart, suggested a study published in February 2015 in Obesity Reviews. How It Works You’ll follow the keto diet as usual until 30 to 45 minutes before exercise - then it’s time to eat about 25 g of carbs, says Daniela Torchia, PhD, a registered dietitian based in Loma Linda, California. The idea is that you’ll have just enough carbs to fuel your workout and still be able to return to ketosis easily after you cool down. Choose carbs that are easy to digest (for instance, white bread or white rice) and be sure not to add calories to your daily total - simply redistribute them, Dr. Torchia says. Some, like Richard Isaacson, MD, director of the Alzheimer’s Prevention Clinic at Weill Cornell Medicine and NewYork-Presbyterian in New York City, are supportive of low-carb diets. “I believe when people are fueling their brain using ketones or calorie or carbohydrate restriction, it’s a cleaner burning fuel, and a better way to delay brain aging,” he says. Still, the evidence isn’t there to say that the keto version of the low-carb diet is always necessary, or even helpful. Indeed, it may benefit some. For example, a small study published in February 2012 in the journal Neurobiology of Aging followed 23 older adults at a higher risk for Alzheimer’s and found that they experienced better memory function after six weeks on a keto diet. For others with certain genetics, though, it may be harmful, says Dr. Isaacson. For that reason, there’s no one-size-fits-all recommendation. Anyone going on keto needs to have his or her labs taken throughout the process, and do it in conjunction with their treating physician and a registered dietitian, he says.
When you consider all of the grain-based foods and sneaky sources of added sugar, it's easy eat a lot more than the recommended amount. Contrary to what social media hashtags would have you believe, there's not much to suggest that it will improve athletic performance. Keto also ranked dead-last (down with another joy-stealer, the Whole 30 Diet) on the U.S. News and World Report's Best Diets list. The lack of research on long-term outcomes, hard-to-follow regimen, and potential health hazards all alarmed the panel of experts. Science simply doesn't support the notion that keto diets keep weight off in the long run, unlike the evidence-backed Mediterranean-style plans. Ketogenic eating may actually increase your risk for kidney and liver problems, plus osteoporosis. Since carb-filled foods contain the highest amount of water and dietary fiber, it's crucial to consider both the immediate side effects (constipation) and future ones (increased risk of GI cancers and decreased immune function) of cutting them out. This version of the diet allows for the lowest amount of carbs (hence being the strictest). According to the Practical Neurology study, 90 percent of daily calories come from fat, 6 percent from protein, and just 4 percent from carbs. Risks to Note The most common side effects among children who followed the diet were constipation, weight loss, and growth problems or anorexia, found the Practical Neurology study. The growth problems among children may be the result of limited protein intake, Spritzler says. There’s also a risk for developing hypercalciuria (high calcium levels in urine), kidney stones, and low blood sugar. Even though the bulk of research has been on children, adults may experience the same issues - plus possibly high cholesterol, though levels should drop once you quit the diet and start eating normally again. Unsurprisingly, this strict version of keto also seems to be the toughest one to stick to: Research shows that the modified versions of the diet have lower drop-out rates.|Certain studies suggest that keto diets may “starve” cancer cells. A highly processed, pro-inflammatory, low-nutrient foods can feed cancer cells causing them to proliferate. What’s the connection between high-sugar consumption and cancer? The regular cells found in our bodies are able to use fat for energy, but it’s believed that cancer cells cannot metabolically shift to use fat rather than glucose. There are several medical studies - such as two conducted by the Department of Radiation Oncology at the Holden Comprehensive Cancer Center for the University of Iowa, and the National Institutes of Health’s National Institute of Neurological Disorders and Stroke, for example - that show the ketogenic diet is an effective treatment for cancer and other serious health problems. Therefore, a keto diet that eliminates excess refined sugar and other processed carbohydrates may be effective in reducing or fighting cancer. It’s not a coincidence that some of the best cancer-fighting foods are on the keto diet food list. Over the past century, ketogenic diets have also been used as natural remedies to treat and even help reverse neurological disorders and cognitive impairments, including epilepsy, Alzheimer’s symptoms, manic depression and anxiety. If you’re insulin resistant, you might need to start lower, around 20 to 30 grams. Hard-charging endurance athletes can often eat 100 grams or more per day and still achieve ketosis. Everyone approaches keto dieting a bit differently. I recommend tracking total carbs instead of net carbs for ease of tracking, and I don’t worry about the carbs in above-ground green vegetables and avocados. If you’re tracking net carbs, 20 to 30 grams net is usually a good starting point. For more information about my approach to keto dieting, check out: Why Does the Keto Reset Allow 50 Grams of Carbs? What is the difference between total carbs and net carbs? Total carbs is just what it sounds like: all the carbohydrates contained in a given food. Net carbs is the total carbohydrate minus any fiber. Some keto plans count net carbs because fiber is not metabolized into glucose, so it doesn’t affect insulin levels or ketosis. How to calculate net carbs on keto?
