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 >>
Ketogenic Diet Faq
With all the new people finding, switching, and transitioning into a low carb diet, I figured it was about time I put together an FAQ on all the common questions that are asked when someone is starting out.

How Long Does It Take To Get Into Ketosis? A ketogenic diet is not a diet that you can whimfully choose to go on and off of at any point. It takes time for your body to adjust and go into a state known as ketosis. This process? Anywhere from 2 – 7 days, depending on your body type, activity levels, and what you’re eating. The fastest way to get into ketosis is to exercise on an empty stomach, restrict your carbohydrate intake to 20g or less per day, and be vigilant with your water intake. To improve the rate at which you enter ketosis, there is a method called Fat Fasting. I’ve written an article on Fat Fasting on a Ketogenic Diet and everything involved with it. Make sure that if you use this method, it is only for a few days, otherwise it can bring harm to you. Where Can I Find Low Carb Recipes? Everywhere on the internet!

The Fat-fueled Brain: Unnatural Or Advantageous?
Disclaimer: First things first. Please note that I am in no way endorsing nutritional ketosis as a supplement to, or a replacement for medication. As you’ll see below, data exploring the potential neuroprotective effects of ketosis are still scarce, and we don’t yet know the side effects of a long-term ketogenic diet. This post talks about the SCIENCE behind ketosis, and is not meant in any way as medical advice. The ketogenic diet is a nutritionist’s nightmare. High in saturated fat and VERY low in carbohydrates, “keto” is adopted by a growing population to paradoxically promote weight loss and mental well-being. Drinking coffee with butter? Eating a block of cream cheese? Little to no fruit? To the uninitiated, keto defies all common sense, inviting skeptics to wave it off as an unnatural “bacon-and-steak” fad diet. Yet versions of the ketogenic diet have been used to successfully treat drug-resistant epilepsy in children since the 1920s – potentially even back in the biblical ages. Emerging evidence from animal models and clinical trials suggest keto may be therapeutically used in many other neurological disorders, including head ache, neurodegenerative diseases, sleep disorders, bipolar disorder, autism and brain cancer. With no apparent side effects. Sound too good to be true? I feel ya! Where are these neuroprotective effects coming from? What’s going on in the brain on a ketogenic diet? Ketosis in a nutshell In essence, a ketogenic diet mimics starvation, allowing the body to go into a metabolic state called ketosis (key-tow-sis). Normally, human bodies are sugar-driven machines: ingested carbohydrates are broken down into glucose, which is mainly transported and used as energy or stored as glycogen in liver and muscle tissue. When deprived of d Continue reading >>
7 Fast And Effective Ways To Get Into Ketosis
If you buy something through a link on this page, we may earn a small commission. How this works. Ketosis is a natural state of the metabolic process. When a person has reached ketosis, their body is burning stored fat instead of glucose. As the body breaks fat down, acids called ketones begin to build up in the blood. These ketones then leave the body in the urine. The presence of ketones in the blood and urine indicates that a person has entered ketosis . Ketosis can help a person lose unwanted fat, as the body starts to break down their fat stores instead of relying on carbohydrates for energy. In addition, some research suggests that ketosis can help suppress a person's appetite, which can also promote weight loss. Achieving a state of ketosis is not always easy. Many people wishing to reach ketosis adhere to the ketogenic diet. In this article, we look at seven ways to get into ketosis fast. We also look at the possible risks of putting the body into this metabolic state. Ways to get the body into ketosis include: A person can get into ketosis by increasing physical activity. The more energy that a person uses during the day, the more food they need to eat for fuel. Exercise helps a person deplete the glycogen stores in their body. In most cases, the glycogen stores become replenished when a person eats carbs. If a person is on a low-carb diet, they will not be replenishing their glycogen stores. It can take some time for the body to learn to use fat stores instead of glycogen. A person may experience fatigue as their body adjusts. 2. Significantly reducing carbohydrate intake Ketosis occurs when a lack of carbohydrate forces the body to use fat as its primary energy source instead of sugar. A person looking to reach ketosis, whether for weight loss, to reduce the Continue reading >>

Ketosis: Metabolic Flexibility In Action
Ketosis is an energy state that your body uses to provide an alternative fuel when glucose availability is low. It happens to all humans when fasting or when carbohydrate intake is lowered. The process of creating ketones is a normal metabolic alternative designed to keep us alive if we go without food for long periods of time. Eating a diet low in carb and higher in fat enhances this process without the gnawing hunger of fasting. Let’s talk about why ketones are better than glucose for most cellular fuel needs. Legionella Testing Lab - High Quality Lab Results CDC ELITE & NYSDOH ELAP Certified - Fast Results North America Lab Locations legionellatesting.com Body Fuel Basics Normal body cells metabolize food nutrients and oxygen during cellular “respiration”, a set of metabolic pathways in which ATP (adenosine triphosphate), our main cellular energy source is created. Most of this energy production happens in the mitochondria, tiny cell parts which act as powerhouses or fueling stations. There are two primary types of food-based fuel that our cells can use to produce energy: The first cellular fuel is glucose, which is commonly known as blood sugar. Glucose is a product of the starches and sugars (carbohydrates) and protein in our diet. This fuel system is necessary, but it has a limitation. The human body can only store about 1000-1600 calories of glucose in the form of glycogen in our muscles and liver. The amounts stored depend on how much muscle mass is available. Men will be able to store more because they have a greater muscle mass. Since most people use up about 2000 calories a day just being and doing normal stuff, you can see that if the human body depended on only sugar to fuel itself, and food weren’t available for more than a day, the body would run Continue reading >>
What Is Ketosis, And How Long Does It Take To Get Into Ketosis?
Ketosis is a natural state of the body in which it is fueled almost solely by fat. This happens when a person fasts or adheres to a very low carbohydrate diet. The exciting thing about ketosis and ketogenic diets is that you can lose a lot of weight while eating a normal quantity of food. You don’t have to suffer through skimpy portions. There are other benefits of keeping a ketogenic diet as well. These will be explained in the following article. An Explanation of Ketosis The root “keto” in the word ketosis comes from the type of fuel that the body produces when blood sugar is in low supply. The small molecules that are used as fuel are called “ketones.” If you consume very few carbohydrates and only a moderate amount of protein, then the body begins to produce ketones. Ketones are made by the liver from fat. Both the body and the brain can use them as fuel. The brain cannot directly function from fat. It must convert the fat into ketones. Legionella Testing Lab - High Quality Lab Results CDC ELITE & NYSDOH ELAP Certified - Fast Results North America Lab Locations legionellatesting.com When you go on a ketogenic diet, your body almost solely runs on fat. Your insulin levels become rather low as well. Since you are burning so much fat, this is a great way to lose weight. Studies show that ketogenic diets result in greater weight loss. The fastest way to get into ketosis is by fasting. However, you cannot fast for very long, so you need to start a low carb diet. The Brain and Ketones Many people think that the brain needs carbohydrates to function. This is not really true. The brain can work well simply by burning ketones. The reality is that many people feel like they have even more energy and focus when they are fueled by ketones. Benefits of Ketosis There ar Continue reading >>
10 Signs Of Ketosis: How To Know If You Are In Ketosis
Carbohydrate restriction and ketosis are the hallmarks of the ketogenic diet. Both confer various benefits and play a major role in the overall success of your new way of eating. Maintaining low carbohydrate intake is simple enough. All you really have to do is stick to a daily carb limit that allows you to get into and stay in ketosis. Knowing the signs of ketosis, on the other hand, can be a bit more confusing. Most of the time it is difficult to tell if you are actually burning ketones for fuel. The multitude of changes that take place while you are first starting the keto diet can cause a lot of confusion as to what is really going on inside your body. To make things much simpler, we decided to put together a quick guide that will help make the question am I in ketosis? much easier for you to answer. Ketosis is the metabolic state that the body enters when it needs to produce ketones for fuel because there is not enough sugar available. Technically, ketosis is reached when blood ketone levels are around 0.5 mmol/ L. People will typically enter ketosis when they restrict carbohydrates (i.e., by following the ketogenic diet) or eat little to no calories (i.e., fasting for multiple days or restricting calories significantly). Depending on the person, their lifestyle, and the severity of their calorie and carb restriction, it can take anywhere from a day to a week and a half for someone to enter sustained ketosis. In general, the body will not enter ketosis as long as there are enough carbs available from the diet or stored glycogen (the storage form of sugar) to provide the cells with energy. As long as sugar is available (and you dont consume exogenous ketones or medium chain triglycerides), your body will do just fine using glucose as its primary fuel source (with s 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 >>

How Long Does It Take To Get Into Ketosis?
Switching to a Ketogenic diet can be exciting, and you may be wondering how long it will be before you can expect to see results or ask “how long does it take to get into Ketosis?” This is perfectly normal, and almost everyone wonders the same thing when they switch to a low carb, high fat diet. The truth is, there is no one size fits all answer; it really does depend on who you are, what you eat, and how long it takes for your body to adjust. The good news is, for most people, this change takes place within a few days or weeks. Keep reading to find out how you can improve your body’s efficiency, and learn how to stay in Ketosis for the long-term. After all, it’s easier to stay in Ketosis once you’re there. How Do I Get into Ketosis? To answer your question of “how long does it take to get into Ketosis,” you must first ask “what is Ketosis” and “how do I get into Ketosis?” Let’s get started: Ketosis is a metabolic process and describes when the body uses fat for fuel. This occurs when there is a lack of glucose. As we generally eat a high carb, high sugar diet in the Western world, most people never enter Ketosis. Just because you lose weight does not mean you are in Ketosis, either, it just means you are eating a calorie deficient. When you switch to a low-carb diet and restrict your glucose, you might experience the Keto flu; these symptoms are your body learning to use fat as fuel, and signaling there is a change. For most people, this is a welcome change, but for other people, the transition takes a few weeks. It can even take a few people months to get into Ketosis, but this is usually because they are not following a strict Ketogenic diet. To get into Ketosis, you must: Eat less than 20g of carbs per day Restrict your intake of protein and Continue reading >>
How Long Does It Take To Get Into Ketosis And Keto-adapt?
How Long Does it Take to Get Into Ketosis and Keto-Adapt? Youve likely heard of the three major macronutrients that provide us with energy: protein, carbohydrates, and fat. However, our bodies can use another substrate as a source of energy, a fourth fuel called ketones. Ketones are produced (and sometimes supplemented) when the body is in a metabolic state of ketosis; one where its breaking down or burning fat. Interestingly, while ketosis is said to be an evolutionary adaptation that allows organisms to survive under conditions of low food availability, newer research is showing that ketones have several diverse and impressive biological roles in the body, and many health benefits. Theyre more than just an energy source. People are becoming aware of the many applications of ketosisincluding weight loss, sports performance, and cognitive function. However, many people might not be aware of how to get into ketosis, how long it takes, and what happens when you do. This article provides all the information you need about entering and staying in ketosis. Before we talk about the specific ways to achieve ketosis, lets go over some basics. Ketosis can be classified in two ways; endogenous (meaning within) or exogenous (meaning from outside). We will only cover some of the basics here, but feel free to check out our in depth article on the fundamentals of ketosis . When we talk about endogenous ketosis, we are referring to the process of the body producing ketones on its own. This happens in the liver. When glucose levels in our body run low and insulin falls, our body begins to burn fat. Free fatty acids (FFAs)the breakdown products of fatare then transported to the liver and used to produce ketone bodies. These ketone bodies are then transported back out of the liver, wher 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 >>
Is Constant Ketosis Necessary – Or Even Desirable?
162 Comments Good morning, folks. With next week’s The Keto Reset Diet release, I’ve got keto on the mind today—unsurprisingly. I’ve had a lot of questions lately on duration. As I’ve mentioned before, a good six weeks of ketosis puts in place all the metabolic machinery for lasting adaptation (those extra mitochondria don’t evaporate if/when you return to traditional Primal eating). But what about the other end of the issue? How long is too long? I don’t do this often, but today I’m reposting an article from a couple of years ago on this very topic. I’ve added a few thoughts based on my recent experience. See what you think, and be sure to share any lingering questions on the question of keto timing and process. I’ll be happy to answer them in upcoming posts and Dear Mark columns. Every day I get links to interesting papers. It’s hard not to when thousands of new studies are published every day and thousands of readers deliver the best ones to my inbox. And while I enjoy thumbing through the links simply for curiosity’s sake, they can also seed new ideas that lead to research rabbit holes and full-fledged posts. It’s probably the favorite part of my day: research and synthesis and the gestation of future blogs. The hard part is collecting, collating, and then transcribing the ideas swirling around inside my brain into readable prose and hopefully getting an article out of it that I can share with you. A while back I briefly mentioned a paper concerning a ketone metabolite known as beta-hydroxybutyrate, or BHB, and its ability to block the activity of a set of inflammatory genes. This particular set of genes, known as the NLRP3 inflammasome, has been linked to Alzheimer’s disease, atherosclerosis, metabolic syndrome, and age-related macular d Continue reading >>

How long to get into ketosis depends on your eating schedule, activity level, carb intake, and a host of other factors. Yes, ketosis is complex. That said, many people start producing ketones within days of going keto. But producing ketones isnt the same as the metabolic state of ketosis, which can take longer. The answer to your sweet tooth. 17g of fat, 3g of net carbs, incredibly delicious. Consider this article your science-based guide on ketosis. Youll learn how long it takes, how to tell if youre in ketosis, and tips for shifting into ketosis. According to some sources, ketosis is defined as having blood ketone levels elevated above 0.3 millimole/Liter (mmol/L)[ * ]. This can be measured with a blood test. Some people will enter ketosis following an overnight fast, while others may require several days of low-carb dieting to start making ketones. Your individual time to ketosis depends on a variety of factors. Youll learn those factors soon, but first a crucial point: having elevated blood ketones doesnt necessarily mean youre keto-adapted or fat-adapted Continue reading >>
