What Is Ketosis? Hint: It Can Help You Burn Fat & Suppress Your Appetite
We’ve longed been told that calorie restriction, increasing exercise and reducing dietary fat intake are the keys to weight loss. But, if you’ve ever attempted to control your weight by subsisting on fewer calories — especially from mostly bland “diet foods”— you’re already probably aware that this typically produces minimal results and is extremely hard to stick with long-term or consistently. Considering the high rates of obesity now facing most developed nations — along with an increased risk for health conditions like diabetes or heart problems as a result — researchers have been anxiously working on how to suppress appetite and achieve weight loss in a healthy, sustainable manner. The keto diet has emerged over the past several decades as one potential answer to this large-scale weight loss problem. (1) While there are some differences in opinion, depending on who you ask, regarding the best approach to very low-carb dieting, studies consistently show that the ketogenic diet (also called the keto diet) produces not only substantial weight loss for a high percentage of people who adhere to it, but also other important health benefits such as reductions in seizures, markers of diabetes and more. The keto diet revolves around eating foods that are high in natural fats, consuming only moderate protein and severely restricting the number of carbs eaten each day. Even if you don’t have much weight to lose, entering into a state of ketosis can be helpful for other reasons — such as for improved energy levels, mental capabilities and mood stabilization. What Is Ketosis? Ketosis is the result of following the ketogenic diet, which is why it’s also sometimes called “the ketosis diet.” Ketosis takes place when glucose from carbohydrate foods (like Continue reading >>
The Ketogenic Diet Might Burn 10 Times More Fat Than The Standard American Diet
Many people who follow the ketogenic diet (a.k.a. keto) are obsessed with its ability to help you lose weight quickly—and keep it off. Now, new research has found that the low-carb diet may have one especially huge perk going for it: It might burn 10 times more fat than other diets. That’s the major finding from research published in the journal Diabetes & Metabolic Syndrome: Clinical Research & Reviews. For the study, scientists took 30 adults who had been diagnosed with metabolic syndrome, a group of health conditions that increase the risk of developing heart disease, stroke, and diabetes. They then randomly put them in three groups: One group ate a ketogenic diet but didn’t exercise, another ate a standard American diet and didn’t exercise, and a third that ate a standard American diet and exercised for 30 minutes a day for up to five days a week. Here’s what they found: In 10 weeks, the group that was on the ketogenic diet had “significant” changes in their weight, body fat percentage, BMI, hemoglobin A1c (a test that measures a person’s blood sugar), and ketones (the result of your body burning fat for energy). Their resting metabolic rate, which is the rate that your body body burns energy when you’re not doing anything, was more than 10 times that of people who ate a standard diet. “All variables for the ketogenic group out-performed those of the exercise and non-exercise groups,” the researchers wrote in the study.

See what happened when one woman tried the ketogenic diet: In case you’re not familiar with it, the keto diet is a high-fat, low-carb diet that encourages followers to get a moderate amount of protein. Carbs are generally replaced with fats, Continue reading >>
Low-carb Athletes Burn 2.3 Times More Fat Than Carb-loaders
A fascinating new study published in Metabolism: Clinical and Experimental may revolutionize our thoughts on sports nutrition. We’ve long understood how glycogen stored in the body and carbohydrates help fuel long distance training. This is why runners, cyclists, triathletes, and other endurance athletes focus on high-carb diets and carb-loading before their events and often before each workout. The study’s findings show that this may not only be unnecessary, but it actually limits the amount of fuel you can utilize from stored body fat. The study out of Ohio State University looked at the fat burning rates of ultra-marathoners and ironman triathletes that either ate a high carb diet (59% carbohydrates, 14% protein, 25% fat) or a low-carb ketogenic diet (10% carbohydrates, 19% protein, 70% fat). As I’ve mentioned before, don’t assume all the findings in athlete studies will apply to your workouts (especially athletes of this caliber), but it is interesting because it highlights previous findings that may be wrong: Humans are capable of burning far more body fat during a workout than we previously thought possible. It may take longer to adapt to a ketogenic diet than we thought. The low-carb athletes had normal glycogen levels before exercise, they utilized their glycogen at the exact same rate, and they even replenished spent glycogen the same as the high-carb athletes. We consider the “fat-burning zone” to be at a VO2 Max below 50 percent, but the highest rate of fat burning occurred at a VO2 Max of around 75 percent. What is ketosis? Low-carb diets are all the rage lately (which is good), but in case you’ve never heard the term ketosis, let me go over it quickly. People assume our body’s preferred source of fuel is carbohydrates because glucose is used Continue reading >>
Water Fasting Ketosis Is Where The Fat Burn Heaven Begins
In this guide, you will learn everything you need to know about water fasting ketosis. I'll explain how water fasting can help you reach your absolute highest possible fat burn rates, which is easily the single biggest benefit of ketosis. You'll also see the science on how long it actually takes before you can enter ketosis during a water fast. You'll also learn about one of the most dangerous problems of water fasting ketosis. I'll also tell you why it is a very good idea to avoid one of the most common mistakes people make once they already reach ketosis during a water fast. Now that you know what you're getting yourself into, here's a quick overview of everything that's covered in this guide: The single biggest benefit of water fasting ketosis Simply put, ketosis is a state where you get to enjoy your absolutely highest possible fat burn rates. If you're on your regular diet, your body can draw energy from a couple of different sources (so not just from your body fat reserves). Those other, non-fat energy sources are the main reason why your fat burn rates stay on the low end, even if you start eating less food. But during a water fast, because you're eating no food at all, those other energy sources in your body will be completely wiped out after a while. Once that happens, your body will enter full ketosis, and in that state of full ketosis, your body will have no choice but to rely almost exclusively on your body fat reserves. With no other energy sources available, ketosis will trigger some pretty amazing fat burn rates in your body. Water fasting is one of the fastest ways to reach that state of super high fat burn. And a lot of people do a water fast just for this reason. There's only one problem with reaching ketosis through water fasting. PRO TIP: A different Continue reading >>
Do Ketogenic Diets Burn More Fat?
It seems like everywhere I go currently, there’s someone hyping up the effectiveness of ketogenesis for fat loss. So what’s all the hype about, and should we be jumping on the hype train? Before I answer those questions – let me say – I’m a fan of ketogenic diets for certain people; but there’s a ton of confusion about them which we really should clear up. This brief article will shed some light on the topic of keto diets by explaining the following: What exactly does ketosis mean? Does ketosis burn more body fat? What are the benefits of ketogenic diets? What is the best diet based on the research? If you’d like more info, I’ve even shared a good little video blog from one of the experts in the field of health and fitness whom I follow. First, lets briefly cover the basics … Ketogenesis refers to a state where the body produces ketones as a substitute energy source to glycogen (carbohydrate). In layman’s terms, when you carb fast you produce ketones so organs in the body don’t die. Ketones are produced in your liver and can replace glucose as fuel for many of the organs in your body, such as your brain, liver and muscles. However, there are also a few systems in your body that will not use ketones as fuel, some of these include your red blood cells and central nervous system. You can categorize each of the organs and tissues in your body as either: Conditional glucose user’s – meaning the conditions in your body will determine if glucose are used such as when carb fasted Obligate glucose users – meaning only glucose can be used as fuel, no matter what the condition or dietary intake of carbohydrate To give you an obvious example, your brain is a conditional glucose user, meaning that if there are glucose present, your brain will opt to use g Continue reading >>
How Much Fat On A Ketogenic Diet?
Do calories matter? How much fat can I eat to lose weight on a ketogenic diet? These are just some of the many questions I focused on when writing this post. What's the Ideal Fat Intake on a Ketogenic Diet? As most of you know, ketogenic diets are high in fat, adequate in protein and low in carbohydrates. The aim of the ketogenic eating is to get your body into a state known as ketosis. Generally, the macronutrient ratio varies within the following ranges: • 60-75% of calories from fat (or even more), • 15-30% of calories from protein, and • 5-10% of calories from carbs. However, percentages are relative and don't say anything about the amount of calories you are eating. Percentages will give you an idea of the macronutrient composition of a diet. To determine the amount of calories, you have to look at absolute numbers - macronutrients in grams. So it's totally different to consume 4,000 kcal and 2,000 kcal on a ketogenic diet. Can I Eat less than 60% of Calories from Fat? Yes, you can. Since you only regulate your energy intake via fat when following a ketogenic diet (protein and carbs remain more or less constant), you may end up eating less than 60% of calories from fat, especially if you are trying to lose weight. This is perfectly fine. In his bestselling books and also in this video, Dr. Stephen Phinney explains the different phases of the ketogenic diet. Depending on your goal, your fat intake will vary in each phase and you will lose different amount of body fat. Weight loss slows down and it's completely natural - you will lose more weight at the beginning (water weight + accelerated fat loss) so don't get discouraged if your weight loss slows down as you get close to your target weight. Why You Need to Use a Keto Calculator Not everyone follows the keto Continue reading >>
How To Burn Stored Body Fat — A Ketosis Primer
“So, how do you tell your body to start burning stored body fat?” my friend and fellow mother asked. “Cut the carbs,” answered another mom. “I go into ketosis just about every afternoon.” “Ketosis? Isn’t that bad for you?” The short answer? No. I talk to a lot of people who want to lose weight. They try all sorts of things — exercise, calorie restriction, you name it. Sometimes, they lose the weight. Inevitably, they gain it back. That’s because what they’re doing is going on a diet — a temporary fix at best. What they need is a lifestyle change, a perspective shift, a new paradigm. Of course, you all know the paradigm I espouse — a conversion to eating real, traditional foods. Yet even a conversion to eating real food won’t necessarily help the pounds melt away. If you’re still eating 200 grams of carbohydrates a day — even if they’re “traditional” carbohydrates like sprouted or soaked grains, unrefined sweeteners, etc, you’re not going to lose weight without making some serious changes. If your body is regularly storing body fat (you gain a little bit of weight each year), then something is wrong with how your body metabolizes food. Let me introduce you to a new concept: the body fat setpoint. The body fat setpoint is the mass of body fat that your body attempts to defend against changes in either direction. It’s your body’s attempt to maintain homeostasis. This is why if you exercise more, you eat more. It’s also why if you restrict calories, your metabolism slows down to compensate. Why should you care about the body fat setpoint? From Stephan at Whole Health Source: We care because this has some very important implications for human obesity. With such a powerful system in place to keep body fat mass in a narrow range, Continue reading >>
Keto Diet Science: How Your Body Burns Fat
By now, you’ve probably heard about the keto diet. You've probably heard that it all but bans carbs and sugars, or that it's been clinically shown to reduce epileptic seizures in kids, or even that it helps people condition their bodies to burn fat. As we detailed in our recent feature on the keto diet, all of those things are true. But as any bodybuilder knows, you don't need to be on the keto diet to burn fat. Heck, you can do it with a focused meal and exercise plan. So we've been wondering: When your body "burns fat" for energy, what's really going on there? How exactly does the keto diet work?

The Ketogenic Diet - Eat Fat To Lose Fat
Fad diets are as American as apple pie. Starting with the Cigarette Diet in 1925, the US has seen the number of prescribed diets grow into the hundreds with more coming out each year. Some of them are legitimate and based on sound research. Others, like the Baby Food Diet, Cotton Ball Diet, and Tapeworm Diet, are less so. Say what you will about fad diets, but there’s no shortage of creativity. One diet that's become very popular in recent years and has been tossed in with fad diets is the Ketogenic or Keto Diet. The diet has actually been around since the early 1900s when it was successfully used to treat epilepsy and brain cancer. But you'd more likely recognize it from online pictures of people drinking butter coffee or eating bowls of bacon. Eating keto means eating fat. Lots of fat - at least 70% of your calories. For the rest, 25% should come from protein and 5% or less from carbs. How Does It Work? In most of the world, carbs are the body’s primary source of energy. To simplify some complex physiology, carbs are broken down into glucose. Glucose is then used to fuel your brain and muscles. Due to the global abundance of cheap carbs - primarily rice, wheat, and corn - this is how most of the world runs. However, there are a few cultures that don't have access to carbs and must use something else for fuel - fat. When your body has no carbs, it naturally will turn to fat for energy. This causes your body to ramp up production of something called ketones and these ketones replace glucose as your body's fuel. When this happens, your body goes into ketosis. This is the goal of the keto diet. That or eating as much Kerrygold butter as possible. What Do I Eat? To get to ketosis, you need to eat a lot of fat. That doesn't mean you've got a green light to pound bacon a Continue reading >>
How Much Fat Should You Eat On A Ketogenic Diet?
Thankfully, the days of low-fat diet fads are mostly behind us, and people are better understanding the importance of eating healthy fats for health. But still, many of those eating keto will underestimate just how much fat they need to eat to see success on this way of eating. So, how much fat can you eat on a ketogenic diet? This article will cover why fat intake matters on the ketogenic diet and how it makes it successful, as well as how to find out how much fat you need. Then, we’ll touch on how you can make sure your fat intake stays high (while still getting enough calories) and the best types of fat to eat. The Importance of Fat on the Keto Diet Dietary fat is the cornerstone of the ketogenic diet. It’s the high fat intake and low carb intake that makes the diet “work” and keeps your body in ketosis — using those ketones for fuel and burning through fat. Having a very low carb intake allows you to deplete your body of carbohydrates and stored carbohydrates (glycogen) and conditioning it to begin turning to fat instead, leading to the creation of ketones for energy. Getting and keeping the body in this state of ketosis has many benefits that include weight loss and better health. High Fat and Enough Calories Matters Those new to keto or who have taken a break from it often struggle with eating enough fat at first. Since you’re greatly reducing your carb intake, you have to really increase your fat intake to replace the calories you were eating before from carbs. This can take some adjustment. If you’re not used to eating high fat, it might seem like a lot at the beginning. Fat is satiating, which is one of the advantages of keto because you can naturally avoid overeating due to its satisfying nature. That being said, it’s important to also eat enou Continue reading >>
Rewriting The Fat Burning Textbook – Part 2: Why You’ve Been Lied To About Carbs And How To Turn Yourself Into A Fat Burning Machine.
In Rewriting The Fat Burning Textbook – Part 1 you discovered how eating a high fat diet doesn’t make you fat, and may actually increase the amount of fat you burn as fuel at both rest and during exercise, allow you to exercise or function for longer periods of time while eating relatively few calories, massively improve your health and not limit performance in the least. But much of that information is theoretical, and not grounded in hard, sweaty numbers. Sure, there are videos such as this that suggest high-fat diets and ketosis-adapted performance can aid with things such as fat loss and high-altitude resilience, but there is scant data related to the pointy end of human performance potential. However, what if we could actually prove that eating a low-carb, high-fat diet for a long time, becoming fat-adapted and even avoiding carbohydrates during the one time when we’re most encouraged to consume carbohydrates (during exercise)… …could actually turn you into a fat-burning machine without losing a shred of performance capability or causing any metabolic damage? That, my friends, would rewrite the fat-burning textbooks. Let’s find out if it can be done… ——————————————– Enter The Exercise Nerds: The FASTER study at the UCONN Human Performance Laboratory As you’ve already learned – from controlling cancer to reducing your waistline to biohacking your brain – a high fat and low carb diet has been shown to massively enhance health, energy levels, and focus while reducing risk of disease. But what does a high-fat diet do to the body when you’re exercising? Does it actually cause you to burn more fat as fuel? Does it mess up your gut? Does it drain precious muscle and liver energy stores? And most importantly: can you turn Continue reading >>
10 Signs And Symptoms That You're In Ketosis
The ketogenic diet is a popular, effective way to lose weight and improve health. When followed correctly, this low-carb, high-fat diet will raise blood ketone levels. These provide a new fuel source for your cells, and cause most of the unique health benefits of this diet (1, 2, 3). On a ketogenic diet, your body undergoes many biological adaptions, including a reduction in insulin and increased fat breakdown. When this happens, your liver starts producing large amounts of ketones to supply energy for your brain. However, it can often be hard to know whether you're "in ketosis" or not. Here are 10 common signs and symptoms of ketosis, both positive and negative. People often report bad breath once they reach full ketosis. It's actually a common side effect. Many people on ketogenic diets and similar diets, such as the Atkins diet, report that their breath takes on a fruity smell. This is caused by elevated ketone levels. The specific culprit is acetone, a ketone that exits the body in your urine and breath (4). While this breath may be less than ideal for your social life, it can be a positive sign for your diet. Many ketogenic dieters brush their teeth several times per day, or use sugar-free gum to solve the issue. If you're using gum or other alternatives like sugar-free drinks, check the label for carbs. These may raise your blood sugar levels and reduce ketone levels. The bad breath usually goes away after some time on the diet. It is not a permanent thing. The ketone acetone is partly expelled via your breath, which can cause bad or fruity-smelling breath on a ketogenic diet. Ketogenic diets, along with normal low-carb diets, are highly effective for losing weight (5, 6). As dozens of weight loss studies have shown, you will likely experience both short- and long Continue reading >>
How To Exercise When You’re In Ketosis
Since going keto means greatly reducing carbs, and since carbs are the body’s primary source of fuel, you might be wondering what your options are when it comes to how to exercise while in ketosis. The good news is that while there are some things to keep in mind, exercise is totally possible on the ketogenic diet and even has some big benefits health- and energy-wise. These are important to know when wading through any misconceptions around low-carb eating and working out. Exercising in Ketosis First, let’s note that the traditional view of weight loss—simply eating less and exercising longer, often with long bouts of cardio—is outdated and unsustainable. In order to see real results when it comes to losing weight and getting leaner, what you eat really matters. A great place to start is checking out a guide on sourcing meat, dairy, and seafood. Therefore, paying attention to the quality of your ketogenic diet itself, and maintaining a steady state of ketosis, is the most important first step you can take. To see if you are actually in a metabolic state of ketosis, testing your ketone levels is vitally important. However, exercise also has many benefits for your health. It’s good for the heart, builds muscle to keep you lean and toned, and strengths the bones. Thankfully, exercise can completely fit into your routine while eating for ketosis. You just need to keep in mind a few simple considerations: Type of Exercise Nutritional needs vary depending on the type of exercise performed. Workouts styles are typically divided into four types: aerobic, anaerobic, flexibility, and stability. Aerobic exercise, also known as cardio exercise, is anything that lasts over three minutes. Lower intensity, steady-state cardio is fat burning, making it very friendly for the Continue reading >>
8 Ketogenic Foods That Can Help You Lose Weight
If you're looking for the most hard core low-carb diet of all the low-carb diets, the ketogenic diet is it. The trendy ketogenic diet, which reportedly has fans like Lebron James and Kim Kardashian, reduces your daily carb intake to 35 grams or less, depending on the plan you follow. That's about the amount in one large apple for the whole day. The theory behind the ketogenic plan is that when your body doesn't have any carbs to use as energy, your liver converts fat into fatty acids and ketones. Then those ketones are used as a primary energy source by your body (meaning you burn more fat each day), says Jim White, R.D., spokesperson for the Academy of Nutrition and Dietetics and owner of Jim White Fitness & Nutrition Studios in Virginia. That whole process is called ketosis. While, in a pinch, ketones can replace carbs as your body’s primary energy source, it often comes at a price. Ketosis can cause side effects like constipation, fatigue, brain fog, and possible nutritional deficiencies, White says. Obviously, we don't recommend any unsustainable eating plan that seriously restricts important nutrients like carbs. However, incorporating certain keto-friendly foods that are rich in protein and healthy fats into a well-rounded diet can get you to your pounds-dropping goals faster. That's because these eats help you build more lean muscle, prevent blood sugar highs and lows, and keep cravings at bay. "Salmon is rich in polyunsaturated omega-3 and omega-6 fatty acids, which you can only get through the food you eat," White says. "Increasing your intake of polyunsaturated fats can help reduce inflammation and therefore improve your ability to lose weight." Plus, salmon is brimming with vitamin E, a powerful antioxidant that can help slash your inflammation levels even Continue reading >>
How Ketosis Helps You Lose Weight Through Suppressed Appetite
One of the reasons The Bulletproof Diet with Bulletproof Coffee works so well for people looking to lose weight is that Bulletproof Intermittent Fasting helps your body to more easily enter a state called cyclical ketosis, which is great for a whole bunch of reasons. Ketosis is a cornerstone of becoming Bulletproof; listen to these recent Bulletproof Radio episodes with ketosis experts Jimmy Moore and Dominic D’Agostino to get the scoop on how and why it works. It’s what happens when your body switches to burning fat instead of sugar for energy, and it only happens when you eat almost no carbohydrates, or when you hack it using certain kinds of oils. Many people first stumble upon the idea of ketosis while looking for a weight loss strategy. That can be a major part of it for so many people out there who have tried just about every other diet out there but haven’t seen the results they’d hoped for. But when people experience the mental clarity and focus that ketosis brings, the game changes! This post walks you through one of the most important yet underrated mechanisms that makes ketosis so effective for people who have tried everything else to lose weight and failed to keep it off: appetite suppression. Ketosis works for weight loss in the short term, but that’s not why it’s so amazing. Short term weight loss is easy (I’ve lost at least 200 pounds of short term weight…because it always roared back on with a vengeance so I could lose it again!) When you look at keeping your weight off forever, ketosis provides a level of appetite suppression that is actually liberating. Ketosis helps you literally stop thinking about food all the time. Why Calorie Counting Is So Ineffective One of the reasons old-fashioned, calorie-restricted diets tend to fail is becau Continue reading >>
