What Is Ketosis?
"Ketosis" is a word you'll probably see when you're looking for information on diabetes or weight loss. Is it a good thing or a bad thing? That depends. Ketosis is a normal metabolic process, something your body does to keep working. When it doesn't have enough carbohydrates from food for your cells to burn for energy, it burns fat instead. As part of this process, it makes ketones. If you're healthy and eating a balanced diet, your body controls how much fat it burns, and you don't normally make or use ketones. But when you cut way back on your calories or carbs, your body will switch to ketosis for energy. It can also happen after exercising for a long time and during pregnancy. For people with uncontrolled diabetes, ketosis is a sign of not using enough insulin. Ketosis can become dangerous when ketones build up. High levels lead to dehydration and change the chemical balance of your blood. Ketosis is a popular weight loss strategy. Low-carb eating plans include the first part of the Atkins diet and the Paleo diet, which stress proteins for fueling your body. In addition to helping you burn fat, ketosis can make you feel less hungry. It also helps you maintain muscle. For healthy people who don't have diabetes and aren't pregnant, ketosis usually kicks in after 3 or 4 days of eating less than 50 grams of carbohydrates per day. That's about 3 slices of bread, a cup of low-fat fruit yogurt, or two small bananas. You can start ketosis by fasting, too. Doctors may put children who have epilepsy on a ketogenic diet, a special high-fat, very low-carb and protein plan, because it might help prevent seizures. Adults with epilepsy sometimes eat modified Atkins diets. Some research suggests that ketogenic diets might help lower your risk of heart disease. Other studies show sp Continue reading >>
Keto-adaptation #1 – Lessons Learned From 1 Year And 5 Months Of Ketosis
Intro Update: before reading this, make sure to know my current thoughts (about page) As of February 2015, I’ve been 1 year and 5 months into ketosis. I entered this metabolic state using nutrition primarily and I was able to maintain it through nutritional, as well as other interventions. More than 98% of the time I was in ketosis. It was, I believe, two or three times when I was out of ketosis for a couple of hours and this happened during the first months, back in late 2013. Be reasonable My personal nutritional approach is individualized. I do not do 80+% fat and 5% carbohydrate and I would be inclined to say that it may not be optimal for healthy adults to eat so much fat and deprive their bodies of micronutrient, vitamin, and mineral diversity that come from vegetables, leafy greens, and/or some legumes, unless a severe medical condition (such as epilepsy, for example) implies it. I do 65-70% fat, 15-18% protein and ~10-15% carbs. It keeps me in ketosis. I eat below my daily energy requirements, I consume low protein, <1g per KG of bodyweight – which fall somewhere in-between 50 – 65g of protein per day, sometimes even lower. I fast a lot, I train fasted and I feel that my lifting performance keeps getting better, contrary to popular belief. Many folks would opt-in for much higher protein intake. I find it not necessary for me. Ketones may play a crucial role in this. Ketosis is not magic. Keto-adaptation does not happen overnight (or in 2-3 weeks of ketosis)1 Eating low calorie does not make me nutrient deficient. On the contrary, I optimized my approach so that I can get as many nutrients from food as possible. I also supplement. I want to underline that this works for me (apparently) and I do not want to get more specific so that folks will immediately th Continue reading >>
Should Endurance Athletes Go Keto? Ketosis And Ketogenic Diets For Endurance Athletes
When it comes to weight loss and endurance performance, dietary ketosis is the strategy everyone is asking about this year. On the surface, ketosis or a ketogenic diet offers everything an endurance athlete could dream of: endless energy, freedom from bonking, and an efficient pathway to weight loss. The diet has been all over mainstream magazines, it’s the subject of several new books, and the supplement companies have already jumped in with new products and a ton of marketing dollars. So, is it time for cyclists, triathletes, and runners to go Keto? First, a refresher course on what a ketogenic diet is. To achieve dietary or nutritional ketosis you need to severely restrict carbohydrate intake (fewer than 50 grams of CHO/day) so the body transitions to using ketones for fueling muscles and the brain. Ketones are produced from fat, which is why nutritional ketosis is so appealing to sedentary people as a weight loss solution. It’s appealing to athletes because we have a virtually unlimited reserve of fat calories to pull from but can only store 1600-2000 calories worth of carbohydrate in muscles, blood, and the liver. An athlete fueled by ketones would be theoretically “bonk-proof”, since bonking is the result of running low on blood glucose. [blog_promo promo_categories=”coaching” ids=”” /] Dietary ketosis for athletes is one of the most hotly contested subjects right now. Proponents point to the metabolic advantage of relying on fat instead of carbohydrate, and critics point out the physiological limitations of eliminating carbohydrate as a fuel for performance. You’ll find bias in both groups, either because scientists and coaches (including me) have been in the high-carbohydrate camp for many years, or because there’s a lot of money to be made b Continue reading >>
Ketosis: What Is Ketosis?
Ketosis is a normal metabolic process. When the body does not have enough glucose for energy, it burns stored fats instead; this results in a build-up of acids called ketones within the body. Some people encourage ketosis by following a diet called the ketogenic or low-carb diet. The aim of the diet is to try and burn unwanted fat by forcing the body to rely on fat for energy, rather than carbohydrates. Ketosis is also commonly observed in patients with diabetes, as the process can occur if the body does not have enough insulin or is not using insulin correctly. Problems associated with extreme levels of ketosis are more likely to develop in patients with type 1 diabetes compared with type 2 diabetes patients. Ketosis occurs when the body does not have sufficient access to its primary fuel source, glucose. Ketosis describes a condition where fat stores are broken down to produce energy, which also produces ketones, a type of acid. As ketone levels rise, the acidity of the blood also increases, leading to ketoacidosis, a serious condition that can prove fatal. People with type 1 diabetes are more likely to develop ketoacidosis, for which emergency medical treatment is required to avoid or treat diabetic coma. Some people follow a ketogenic (low-carb) diet to try to lose weight by forcing the body to burn fat stores. What is ketosis? In normal circumstances, the body's cells use glucose as their primary form of energy. Glucose is typically derived from dietary carbohydrates, including: sugar - such as fruits and milk or yogurt starchy foods - such as bread and pasta The body breaks these down into simple sugars. Glucose can either be used to fuel the body or be stored in the liver and muscles as glycogen. If there is not enough glucose available to meet energy demands, th Continue reading >>
I Tried The Viral Diet That Lets You Eat Heavy Cream And Steak — And It Was Harder Than I Thought It Would Be
The Ketogenic diet is a high-fat, low-carb diet. It's gotten really popular lately as a way to lose weight relatively quickly while eating a lot of foods you'd have to give up on other diets. I tried it for a week to see what it's like. Chances are, at least one of your Facebook friends has tried the Ketogenic diet lately. And though you may have seen photos of their meals on your feed, you may not be sure what it is. Essentially, when going "Keto," you bump up your fat intake while severely limiting carbs. This diet says that you can eat full-fat cheese, bacon, butter, and other things that most other diets frown upon, so it's maybe not that surprising that some keto converts become enthusiastic loyalists, shouting the tenets of the plan wherever they go. Georgie Fear, a registered dietitian and sports nutrition specialist, told INSIDER that the major pro of the diet, besides getting to eat all of those things that are off-limits on other diets, is that you don't have to worry about how many calories you're eating or worry about the old "everything in moderation" adage. But there are some potentially major health-related drawbacks to eating this way as well. "You are at an increased risk of bone fractures, and up to a one in four chance of having kidney stones," Fear said. "It also causes fatty liver and gallstone formation. Low carbohydrate diets also worsen athletic performance and many people report low energy, nausea, and fatigue. High saturated fat diets are known to induce insulin resistance and hypothalamic inflammation leading to dysregulation of energy intake favoring obesity. Gut bacteria populations shift in a high fat, low carbohydrate diet, and emerging research is uncovering links between these changes and worsened risk of mental illness, immune system dy Continue reading >>
Why This Doctor Recommends Keto (with A Catch)
Would clinical nutritionist Dr. Josh Axe, DNM, DC, CNC, recommend the keto diet? "Absolutely," he told POPSUGAR. But there is a catch. You can't do it forever. A brief refresher, if you don't already know: the keto diet is a high-fat, moderate-protein, low-carb diet in which you switch your body's primary energy source from carbohydrates to fat (i.e., from glucose to ketones). Up to 80 percent of your calories come from fat — we're not kidding when we say high-fat! That's what differentiates this diet from something like Paleo or Atkins — they're both low-carb, but with keto, the emphasis is on the fats. "I don't think somebody should be on a full ketogenic diet for more than three months," he said. "What I teach is not that everybody should be on a ketogenic diet — the basis of what I teach is traditional Chinese medicine, or TCM — but if somebody has the goal of overcoming epilepsy, fighting cancer, overcoming blood sugar issues like diabetes, losing weight, or even some hormonal issues, the ketogenic diet is a great temporary diet." "Everybody is different; depending on somebody's genetics, depending on somebody's health goals or struggles, certain people should be on certain diets," said Dr. Axe. For the patients he believes need the keto diet for what he calls "a breakthrough" in their health, he likes to limit it to three months. "When I put my patients on it, it has been for a maximum of three months. I know some people who have been on [the keto diet] and have done it for a year and done well with it. But I don't think people should be on a ketogenic diet fully for more than a year — absolutely not for more than a year." His reasoning for this is rooted in human history and the biology of our ancestors. As Dr. Axe is a clinical nutritionist with method Continue reading >>

Ketosis: What It Is, If Its Safe, How To Achieve It, Symptoms, And More | Everyday Health
Following a low-carb, high-fat diet by omitting things like grains and eating foods like eggs, can turn your body into a fat-burning machine through a process called ketosis. Ketosis carries some risks, but it may lead to fast weight loss. If you research different ways to lose weight, youll come across various diets and lifestyle tweaks to turn your body into a fat-burning machine. Increasing the intensity of your workouts is one way to lose body fat and trim your trouble spots, but its not the only way. You can also burn more fat through a metabolic state called ketosis. Understanding what ketosis is and learning how to achieve this state can help you whip your body into shape. But before you attempt to achieve ketosis, you should know a few things about the process, including its potential health risks. What Is Ketosis, and How Does It Affect Weight Loss? Food is your bodys primary source of energy, and three main nutrients in foods supply your body with this energy. These are carbohydrates, fat, and protein. Typically after eating a meal, your body will first break down carbohydrates from foods, and then fat and protein. Ketosis is a natural metabolic state that occurs when your body doesnt have enough carbs (or glucose) for energy, so it burns fat instead. Ketosis happens when your carbohydrate intake is low. As your body breaks down fat, it produces an acid called ketones or ketone bodies, which becomes your body and brains main source of energy. Because ketosis shifts your metabolism and relies on fat for energy, your body can burn fat at a higher rate. Translation? You may reach your weight loss goal sooner than if you didnt cut carbs at all.

Keep Yourself In Ketosis
When talking about a Grain Brain lifestyle, and the very similar ketogenic diet, it’s frequently mentioned that we are aiming to keep our bodies in ketosis. However, if you’re new to my work, it may be that you’re not exactly sure what ketosis is, or why we should be worrying about getting our body into this state. Allow me to explain. Ketones are a special type of fat that can stimulate the pathways that enhance the growth of new neural networks in the brain. A ketogenic diet is one that is high in fats, and this diet has been a tool of researchers for years, used notably in a 2005 study on Parkinson’s patients finding an improvement in symptoms after just 28 days. The improvements were on par with those made possible via medication and brain surgery. Other research has shown the ketogenic diet to be remarkably effective in treating some forms of epilepsy, and even brain tumors. Ketones do more than just that though. They increase glutathione, a powerful, brain-protective antioxidant. Ketones facilitate the production of mitochondria, one of the most important actors in the coordinated production that is the human body. And that’s just the tip of the iceberg. Our bodies are said to enter ketosis at the point when blood sugar levels are low and liver glycogen are no longer available to produce glucose as a fuel for cellular energy production. At this point, not only is the body doing the natural thing, and burning off fat, it’s also powering up the brain with a super efficient fuel. We can jump start ourselves into ketosis with a brief fast, allowing our body to quickly burn through the carbs that are in our system, and turn to fat for fuel. A ketogenic diet is one that derives around 80% or more of of its calories from fat, and the rest from carbs and prote Continue reading >>
A Beginner’s Guide To The Ketogenic Diet: An Effective Way Of Optimizing Your Health
Many Americans suffer from various chronic diseases such as diabetes and obesity, and the main culprit is usually the food they eat. The standard American diet contains excessive amounts of protein and carbohydrates, neither of which is good for your health because it eventually causes you to develop insulin and leptin resistance. As a result, you gain excess weight, develop inflammation and become prone to cellular damage. To avoid this problem, significant changes in your diet are necessary, and the best way is inducing your body into a state of nutritional ketosis, a condition where your body burns fat as its primary fuel instead of sugar. In order to reach nutritional ketosis, you must follow a ketogenic diet. But what exactly is a ketogenic diet? This guide will tell you everything you need to know about a ketogenic diet – how you can apply it to your lifestyle and what positives you can reap from it. The Various Benefits of the Ketogenic Diet A ketogenic diet is a dietary approach that focuses on minimal carbohydrates, moderate amounts of protein and high healthy fat consumption — the three keys to achieving nutritional ketosis. In fact, it’s what I recommend for most people who would like to optimize their health. There are many reasons why you should try a ketogenic diet. It can be very beneficial for people suffering from chronic conditions, or for people who would simply like to be healthier than their current state. You’ll be excited to know that a ketogenic diet can help with the following: • Weight loss If you’re trying to lose weight, then a ketogenic diet is one of the best ways to do it, because it helps access your body fat so that it can be shed. Obese people in particular can benefit from this method. In one study, obese test subjects were Continue reading >>
Adverse Reactions To Ketogenic Diets: Caution Advised
As the ketogenic diet gains popularity, it’s important to have a balanced discussion regarding the merits of this diet. Let me emphasize right out of the gate that this is not a diet without merits (excuse the double negative); in fact, it has significant therapeutic potential for some clinical pathologies. However, it is also a diet with inherent risk, as evidenced by the extensive list of adverse reactions reported in the scientific literature—and this has not yet been a thorough enough part of the public discussion on ketogenic diets. The AIP Lecture Series is a 6-week video-based, self-directed online course that will teach you the scientific foundation for the diet and lifestyle tenets of the Autoimmune Protocol. This is the first of a series of articles discussing various facets of a ketogenic diet with an inclination toward balancing the discussion of the pros and cons of this high-fat, low-carb, low/moderate-protein diet. My interest in this topic stems from concerns I have over its general applicability and safety, simultaneous with its growing popularity. I feel a moral and social obligation to share what I understand of these diets, from my perspective as a medical researcher. The dangers of a ketogenic diet was, in fact, the topic of my keynote presentation at Paleo F(x) this year (links to video will be provided once available). This series of articles will share the extensive research that I did in preparation for this presentation, including all of the topics covered during my talk as well as several topics that I didn’t have time to discuss (also see the free PDF Literature Review at the bottom of this post). For every anecdotal story of someone who has regained their health with a ketogenic diet, there’s a counterpoint story of someone who derai Continue reading >>

Most of us would say we get fat simply because we get lazy and eat more. But what if it's the other way round? What if we just get fat and as a result we eat more and become lazy? For the last decades we have been given wrong advice about nutrition and effects of fatty foods on putting on weight. What if the main problem is that due to our modern diets we cannot satisfy our appetite? A study on this subject concluded with a surprising result: the fatter people get, the more inactive they become, not the other way round. And what if the interests of the authorities offering advice are influenced by economic reasons? To learn more about this, I recommend you watch The Food Revolution on Youtube Ketogenic diets are, in fact, closely related to the Paleolithic diet. Both exclude carbohydrates and aim at eating real food. Today carbohydrates make the majority of our diet and have significant implications for our health including hormone balance. For example, insulin, which is responsible for storing fat in our body, is greatly affected by excessive carbohydrate consumption. Carbohydrates are without doubt the most fattening element in our diets. Based on studies performed over th Continue reading >>
How Long Can You Eat Ketogenic? Isn't It Dangerous In The Long-term?
1) Is Keto diet dangerous for the liver, the kidneys, the heart? Especially the way the body has to work to turn fats into glyco for the body. Is it harmful in anyway? There’s no evidence to suggest that it is harmful to any of the organs you mention. There is no evidence to suggest that it is harmful to you in any way, really. There is a lot more evidence that a Low Fat diet it much more harmful in almost every way. It’s actually VERY normal for the human body to spend generating most of its glycogen from fat (ie, being in the “Fat burning zone” of cardio). Insulin tells your cells to take up glucose and store it - for fat cells that means turning it into fat - which is then later turned back into glycogen once the blood glucose levels drop. 2) Is it a diet I can stay on, on a lifelong basis? Because I don’t want to gain all my weight back in the end, I want to continue my sports sessions and I want to be in good health. Is keto diet compatible with that? And yes, it’s very compatible with that. You can find evidence of powerlifters, cyclists, and everything in between thriving on a ketogenic diet. Until you get adapted it can be pretty tough (maybe a month or two), but once you are, you will not notice adverse effects. I will tell you though, it it challenging to do mostly because it seems EVERYTHING in the WHOLE WIDE WORLD except what you cook at home or Chipotle is just full of carbs - so I always feel like I’m fighting a battle against the world to maintain the diet when I am in any situation that is outside my “normal” routine.

The Paleo Guide To Ketosis
Ketosis is a word that gets tossed around a lot within the Paleo community – to some, it’s a magical weight-loss formula, to others, it’s a way of life, and to others it’s just asking for adrenal fatigue. But understanding what ketosis really is (not just what it does), and the physical causes and consequences of a fat-fueled metabolism can help you make an informed decision about the best diet for your particular lifestyle, ketogenic or not. Ketosis is essentially a metabolic state in which the body primarily relies on fat for energy. Biologically, the human body is a very adaptable machine that can run on a variety of different fuels, but on a carb-heavy Western diet, the primary source of energy is glucose. If glucose is available, the body will use it first, since it’s the quickest to metabolize. So on the standard American diet, your metabolism will be primarily geared towards burning carbohydrates (glucose) for fuel. In ketosis, it’s just the opposite: the body primarily relies on ketones, rather than glucose. To understand how this works, it’s important to understand that some organs in the body (especially the brain) require a base amount of glucose to keep functioning. If your brain doesn’t get any glucose, you’ll die. But this doesn’t necessarily mean that you need glucose in the diet – your body is perfectly capable of meeting its glucose needs during an extended fast, a period of famine, or a long stretch of very minimal carbohydrate intake. There are two different ways to make this happen. First, you could break down the protein in your muscles and use that as fuel for your brain and liver. This isn’t ideal from an evolutionary standpoint though – when you’re experiencing a period of food shortage, you need to be strong and fast, Continue reading >>
How Long Can You Stay In Ketosis Safely?
Are you looking for a diet for weight-loss or fat-loss? If so then you might be interested in ketosis. The question is whether you can stay on it permanently. That’s because it’s critical for any ‘diet” to become part of your everyday life and eating habits. It’s important to first understand what it is all about. It’s a natural state of the human body when it’s fueled almost 100% by body fat. This state takes place during a low-carb or “keto” diet as well as during fasting. It’s important to understand how this process is related to fat loss. The term originates from the fact that the human produce produces tin fuel molecules known as “ketones.” When the body doesn’t have enough blood sugar/glucose it gets energy from this source. The body produces chemicals when it gets a very low supply of carbs and a moderate amount of protein. The liver’s fat produces ketones then the body and brain use it for fuel. The process is especially important for the brain since the organ can only run from glucose/ketones. Medical research shows that early humans probably experienced the state very often. The reason is that hunter-gatherer societies ate a high-meat diet and had less access to carbohydrates than modern humans. As a result human bodies evolved so they could get energy from fat even though it mimicked starvation mode. Today there are various reasons why people use the ketogenic meal plan. Some of the most common ones are to lose weight or control epilepsy. The firm supporters point out the health benefits of the diet but others note that it’s a dangerous “hack” of the body’s regular metabolic system. These are the benefits to this process: Less eating due to no appetite More fat loss from abdominal cavity Lower blood sugar/insulin levels Lo Continue reading >>
The Beginners Guide To Ketosis: Investigating Low-carb, High-fat Eating
The only hard and fast rule of health is that health is personal and what works well for one person may not work for someone else. Aside from that rule, there are “frameworks” that seem to benefit large groups of people. One more level down from that are alternative strategies that benefit smaller groups. Ketosis is likely one of those alternative strategies that works well for certain, smaller groups of people. So, right off the bat I want you to understand that Ketosis might not be for everyone. I’m going to lay out the case for potential benefits of Ketosis. If it sounds interesting and beneficial to you, then consider trying it. (see our free cheat sheet to help you). What is Ketosis Ketosis occurs when liver glycogen gets depleted and the body burns fatty acids for fuel. The primary driver of this state is a very low carbohydrate intake. Often, it also requires a low protein, higher fat intake. You can also achieve a state of ketosis by not eating altogether. The creation of ketones is a byproduct of this metabolic state. Ketones are a source of fuel, just as glucose is a source of fuel. Ketones tend to have some added benefits, though. What role does Ketosis play in human health? Ketosis allows our bodies to function in the absence of carbohydrates, both physically and mentally. Instead of burning carbohydrates, or converting protein to glucose, the body burns ketones. This is pretty much a survival mechanism. It allows your body to function in a state of caloric deprivation. This is why ketosis often gets bad press (as it’s linked to “starvation”). Being a survival mechanism doesn’t make it invalid as a strategy, though. There can still be potential benefits to be had. Let’s cover a few of them… Ketosis and Accelerated Fat Loss Being in ketosis Continue reading >>
