There is a lot of confusion about the term ketosis among medical professionals as well as laypeople. It is important to understand when and why nutritional ketosis occurs, and why it should not be confused with the metabolic disorder we call ketoacidosis. Ketosis is a metabolic state where the liver produces small organic molecules called ketone bodies. Most cells in the body can use ketone bodies as a source of energy. When there is a limited supply of external energy sources, such as during prolonged fasting or carbohydrate restriction, ketone bodies can provide energy for most organs. In this situation, ketosis can be regarded as a reasonable, adaptive physiologic response that is essential for life, enabling us to survive periods of famine. Nutritional ketosis should not be confused with ketoacidosis, a metabolic condition where the blood becomes acidic as a result of the accumulation of ketone bodies. Ketoacidosis can have serious consequences and may need urgent medical treatment. The most common forms are diabetic ketoacidosis and alcoholic ketoacidosis. What Is Ketosis? The human body can be regarded as a biologic machine. Machines need energy to operate. Some use gasoline, others use electricity, and some use other power resources. Glucose is the primary fuel for most cells and organs in the body. To obtain energy, cells must take up glucose from the blood. Once glucose enters the cells, a series of metabolic reactions break it down into carbon dioxide and water, releasing energy in the process. The body has an ability to store excess glucose in the form of glycogen. In this way, energy can be stored for later use. Glycogen consists of long chains of glucose molecules and is primarily found in the liver and skeletal muscle. Liver glycogen stores are used to mai 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 >>
Juice Fasting For Ketosis
Ketosis — when your body burns primarily fat for fuels — requires a very low dietary carbohydrate intake. A juice fast requires you to consume practically nothing but carbohydrates. A ketogenic diet, such as Atkins or other forms of low-carbohydrate diets, remains completely incompatible with any juice-based diet. If you wish to lose fat, you must select one or the other. Consult a health care practitioner before beginning any dietary program. Video of the Day Your body can run on several types of fuel: amino acids, sugar and fat. When your body burns primarily fat, or free-floating fatty acids called ketones, you are in dietary ketosis. To achieve this, you must severely restrict your intake of all non-fibrous carbohydrates. Exercise will allow you to further deplete your glycogen reserves; over time, your body will shift from running on sugar to running primarily on ketones. Sugar and Ketosis If you consume sugar while in ketosis, you will shift back into burning glycogen or sugar. It will take time to achieve ketosis again. The volume of carbohydrates that you consume will have the most bearing on this; however, consuming carbohydrates and fat together is even worse. This is because your body will generate a great deal of insulin in response and you will continue to run on glycogen while your body stores the fat you just ate. While juice contains no fat, it usually contains fructose. The juice may be predominantly fructose, depending on its type. Fructose is ordinarily a good energy source, largely due to its limited ability to cause a large spike in insulin levels; however, it is far less than ideal if you wish to remain in ketosis. Unlike many other types of sugars, fructose is broken down primarily in the liver. While your body is metabolizing fructose, your a Continue reading >>
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 >>
The Perks Of Fasting, With None Of The Work
“If there’s a downside, it is kind of crazy tasting,” said Geoff Woo, the founder of HVMN, a Silicon Valley company that makes nootropics, or performance-enhancing supplements. We were in a conference room in The Atlantic’s office building, and he was bracing me for my trial run of his latest product. It was a small, clear vial labeled “Ketone,” a new type of energy drink his company is releasing this week. Its nutrition label says it contains 120 calories, but no carbs, no fat, and no protein. Instead, it’s all ketones, the chemical that Woo and his company are calling a “fourth food group.” He hopes the drink will allow people to reap the benefits of occasional fasting—high ketone levels inside the body—without actually having to not eat. I unscrewed the top and, college-days muscle memory kicking in, chugged it like a shot of Captain Morgan. It tasted like cough syrup that had been poured into a garbage bag and left in the sun. “Augh!” I cried. “I compare it to a combination of a liquor shot with nail-polish remover,” Woo said. Woo’s coworker, Brianna Stubbs, went to fetch me a glass of water. “We’ve done a lot of work to make it better,” she said. Within an hour, the drink was supposed to help improve my athletic performance by changing how my body burned energy during exercise. Some people also say it helps them feel more energetic and focused on their work. About 25 minutes after I drank Ketone, Woo and Stubbs pricked my finger to see if it was working. My blood sugar, which had verged on diabetic levels from some pineapple I had eaten that morning, was down to near-normal levels. Meanwhile, my ketones, which had been practically nonexistent before imbibing—measuring just 0.2 millimolar—had soared to 4.9. “It would have Continue reading >>

Studies In The Ketosis Of Fasting
A series of experiments was performed during the induction of starvation ketosis and in the acute reversal of the ketotic state. In contrast to the predictions of two widely held theories of ketogenesis, control of acetoacetate production by the liver appeared to be unrelated to changes in fatty acid mobilization from the periphery, fatty acid oxidation, fatty acid synthesis, or the acetyl coenzyme A concentration in the liver. Ketosis of fasting was shown to be reversible within 5 minutes by the injection of glucose or insulin. This effect was due to a prompt cessation of acetoacetate production by the liver. The possibility is raised that the ketosis of fasting is due to a direct activation of acetoacetate-synthesizing enzymes secondary to a starvation-induced depression of insulin secretion by the pancreas.

Complete Guide To Intermittent Fasting
Before I gave up grains, sugar and other foods which I used to believe were healthy (or at least not harmful), I had breakfast every single day. At least that's what all kinds of TV ads were claiming, promoting whole grains and cereals and other "healthy" breakfast options often loaded with sugar. Just the thought of skipping a meal made me feel guilty. Doing a full day fast seemed unnecessary and impossible to follow. But all this has just been part of the big high-carb, low-fat campaign. Myth #1: Breakfast is the most important meal of the day. As you will learn in this post, nothing can be further from the truth. I rarely eat breakfast - that's the meal I skip almost every day. Myth #2: You have to eat regularly, ideally 5 small meals a day. Once you get keto-adapted and not depended on glucose, this will change. Since your insulin levels will not spike, you won't have the need to eat regularly or in small portions (apart from diabetics which I discuss later in this post). Myth #3: You need to eat most of your carbs for breakfast because that's when your body uses them most effectively. You should try to eat your carbs throughout the day and not just in one meal. Furthermore, since our body is in fat-burning state in the morning, eating carbs in the second half of the day is more beneficial for weight loss. Myth #4: Never exercise on an empty stomach. It's bad for your performance and you'll lose muscles instead of body fat. As described below, for most people Intermittent Fasting is ideal for maximising the benefits of exercise for several reasons. What is Intermittent Fasting (IF)? Compared to calorie restriction, IF is not restricted in calories - it simply limits your eating windows to just a few hours a day. In effect, you usually fast for 14-20 hours or even up Continue reading >>

Bulletproof Intermittent Fasting: Lose Fat, Build Muscle, Stay Focused & Feel Great
If you want to lose fat and improve your health as fast as possible, without feeling mentally slow, it’s hard to beat Bulletproof Intermittent Fasting. Here’s an overview of the protocol, which I lay out in more detail in my new NYT bestseller The Bulletproof Diet. Plain intermittent fasting has become popular in biohacker circles because it shows tremendous promise for fat loss, preventing cancer, building muscle, and increasing resilience. The most popular site that covers plain intermittent fasting is Leangains.com. It’s totally worth a visit. The basic idea behind plain intermittent fasting is to eat all of your daily food in a shortened period (8 hours in the case of Lean Gains) and fast the rest of the time. For reasons we will get into below, this tells your body to simultaneously build muscle and burn fat. It really works. The problem is not everyone does well with fasting. If you’re a busy entrepreneur or even a student who needs to be in a high performance state all day, dealing with hunger can be a distraction. It’s much worse for those with an impaired metabolism (i.e. the people who need to lose weight). If you have more than 30 pounds of extra fat or if you’re facing diabetes, it can be hard to skip meals and still get things done. As explained in The Bulletproof Diet book, Bulletproof Intermittent Fasting is an easy biohack that changes that and makes it possible to lose fat and build muscle faster than plain intermittent fasting… without feeling hungry or tired. Introducing Bulletproof Intermittent Fasting Bulletproof Fasting is the same as intermittent fasting, except you consume a cup of Bulletproof Coffee in the morning. The healthy fats from grass-fed butter and Brain Octane Oil give you a stable current of energy that sustains you thro Continue reading >>
Tim Ferriss – 3 Day Fast Protocol Details – Get Into Ketosis Quicker And Easier
In Tim Ferriss’ new book Tools of Titans he puts forward a method to optimize the process of fasting. In his typical 80/20 style, he aims to get the most benefits, in the least amount of time. His recommended fast is conducted in a 3 day period, spanning Thursday evening to Sunday evening. 3-Day Fast Overview Stop eating Thursday night Friday morning go for a long walk to accelerate your transition into ketosis Friday and Saturday stay fasted, and consume moderate amounts of exogenous ketones and MCT oil (as needed), to give you a boost while you’re keto adapting. Sunday evening you break the fast. Here’s the process in more detail if you don’t have Tools of Titans to hand: Thursday Evening Eat a low carbohydrate dinner around 6pm. Make that the last meal of the day. Go to bed as normal. Friday Morning Drink some caffeine if needed, then get out the door and walk within 30 minutes of waking. Bring at least 1 litre of water, with some added salt (to prevent headaches/cramping), and sip as you walk. Walk for 3-4 hours(!). Filling up/buying more water as needed. Arrange phone calls for this time, to make the time productive. The idea behind the walk is that you use up your glycogen stores, forcing your body to move quicker into deep ketosis. The quicker you get into ketosis, the less time you spend feeling sub-optimal, and the less potential muscle wastage. Friday Day (post walk) Consume exogenous ketones or MCT oil 2-3 times throughout the day, where necessary. Tim primarily uses KetoCaNa & KetoForce as exogenous ketone sources. Both these products contain 11.7g of Beta-hydroxybuterate per serving, and each contain 16 servings. The key difference is that KetoForce is an unflavoured (alkaline) liquid. And KetoCaNa is an orange flavoured powder you can mix into wate Continue reading >>
Intermittent Fasting And Ketosis – Different Perspectives
My belief is that we are not meant to eat 3 times a day, which is the general R(x) in most countries. People eat much more than that, as you see the ones near you always having something to put in their mouths, always craving for something. It’s extremely easy to get food these days, with basically 0 effort. I do not want to be a critic but look at the Chawners for example, the fattest British family. They are not employed and they live off the government receiving approximately $20,000. Again, the purpose is not to criticize but to point out how easy it is to receive food. I don’t wanna say that their morbidly obese status has something to do with the amount of food they eat, but in some part, it has. Currently and as far as I know, there are more obese people than starving people in the world. Not wanting to derive away from the subject, let me give you some examples why I think it’s no good for us to eat at least 3 times a day and to eat every day. Let’s start with some history. Early Ancestors Enter the Australopiths (a.k.a. Australopithecus). They have been a hominid species living mostly in Africa between 4.2 to 1.5 million years ago. First of all, their upper body size is much more developed (larger) compared to the lower body size. These images (even though they may not 100% reflect the reality of the past) show that their hands were bigger than their feet. You cannot see in these images, but the Australopiths had flat feet, making them less adapted to moving faster and over larger distances. You may have heard of Lucy, the recently discovered fossil. She was an Australopith female living in Ethiopia 3.2 million years ago. They’ve evolved from earlier primates and they could spend time both in trees and on the ground, constantly reaching for food (henc Continue reading >>
Does Intermittent Fasting Induce Ketosis?
So I searched around for a while but couldn't find a definitive answer (maybe there isn't one), does intermittent fasting induce ketosis? I usually IF overnight until lunch-time. I've read that sleep often induces ketosis. Am I in ketosis at the end of that fast? Continue reading >>
How Do You Fast Into Ketosis?
It is a common misconception that you will start to burn muscle if you fast. In fact, when you are fasting, you have higher than normal levels of human growth hormone, which protects muscle. Many body builders now work out on a fast because the hormonal changes during fasting allow them to burn more fat and build more muscle. I like the explanation in Jason Fung’s book: we store fat, not muscle, so when we fast it makes no sense that we would start burning muscle and not fat. He says it would be like saving up firewood all year round and then, when winter comes, throwing you sofa into the fire! What in reality happens is that you first burn off all your glycogen stores, and then you switch to burning fat. You don’t need to do anything, just don’t eat! Stay well hydrated using water, black tea and coffee, and herbal teas. Someone mentioned high protein meal replacements: these won’t allow you to enter into a proper fast, and in fact excess protein converts to sugar in the body via gluconeogenesis. Here is an article I wrote on the benefits of fasting and the different ways to fast, including intermittent fasting and longer fasts. Continue reading >>
What Is Ketosis?
Our bodies’ metabolisms are complicated, fluid systems that have many characteristics. They’re very transient in nature and adapt to the inputs we provide our bodies with. One adaptation state called ketosis, is the state of having elevated ketone levels, typically above 0.5 mM. Whether or not we have ketones in our body is based on the inputs we consume or omit. A state of endogenous Ketosis essentially means the body is in “fat-burning mode” and is a metabolic shift as the body prioritizes ketones and fats over carbohydrates in the hierarchy of energy substrates. In order to understand ketosis a little more, we must first understand what fuel sources our body can use for energy. We usually think of carbohydrates, fats, and proteins as being the only available fuel sources for our body. Whilst many parts of the body can use a combination of these fuels, the brain depends heavily on the breakdown of carbohydrates into glucose for fuel. This is due to the fact that fats cannot easily cross the blood-brain barrier to fuel the brain. Carbs. Many have a love/hate relationship with them. They taste good and they make us feel good. However, these feelings only last so long and soon many of us find ourselves with cravings galore. If carbohydrates stop coming into the body and carbohydrate stores in the body are depleted, a cascade of hormonal signals causes the body to increase the release of stored fats. In the liver, these fats are converted into ketones which can provide up to 60% of the brain's energy requirements1. Unlike fats, ketones can cross the blood-brain barrier and are readily used as a fuel for the brain. Ketone metabolism ensured that prehistoric man could survive periods of fasting and carbohydrate deprivation2. Achieving Ketosis So how does one go abou Continue reading >>
