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 >>
The Results Of My Four Day Fast To Start A Ketogenic Diet
Greetings Ketonians! Dr. Anthony Gustin writing to you today. Many of you know I created Perfect Keto to help ketosis be accessible to everyone who wants it, and that includes me. One of my favorite quotes from Fr. Peter Drucker is, That’s why I encourage everyone on a ketogenic diet to test their ketone levels. I’m taking it about 10 steps further than just ketone blood tests by conducting an intensive two-month ketosis experiment on myself to learn precisely what changes occur in my body in ketosis. I began with a four day fast and I’m pleased to share that the results are in! They truly rocked all the old ideas I had about fasting and ketosis and I can’t wait to share them with you. If you think I’m nuts and wondering why the hell I would fast, start by reading my article about why I am choosing to fast here. The reason is I wanted to maximize my transition into ketosis. I’ve tracked body composition, lab blood work, ketone levels, microbiome tests and other noteworthy biomarkers to answer the questions I had for myself. Does fasting lead to massive lean tissue losses? Does it destroy your metabolism? Is it unbearable? Does it sap your energy? All of these questions and more are answered in this article. The Results of My Four Day Fast to Start A Ketogenic Diet Since there’s about a 0.003984% chance you read linked article about fasting, let me explain something from the start, this fast was never going to be a water fast. There are a few reasons to not do a water fast, but we won’t get into that here. We’ll get into what type of fasts I’m now doing regularly and why. My fast was similar to what researcher Valter Longo has shown to actually be preferential to a water fast in many ways, in what he dubbed the “fasting mimicking diet.” Much of hi Continue reading >>

Intermittent Fasting On A Keto Diet
Intermittent Fasting, or “IF”, is a relatively new craze that is used as a supplement to your diet. It revolves around the timing of your food intake, and can have some benefits in the long run. There are quite a few people misinformed on fasting, so we’ll clear that up and explain how intermittent fasting can be useful. On your ketogenic journey, it’s important to know that your success is not only dictated by eating enough fat and protein and restricting carbs. When you eat, how often you eat, and how much you eat have a substantial impact on your health and function as well. If your results have plateaued or you are thinking of starting a ketogenic diet, this article will provide you with a way to lose more fat and improve energy levels called intermittent fasting. If you need to learn how to calculate your macros, visit our Keto Calculator. Fasting isn’t required to lose weight on a ketogenic diet. If it doesn’t work for you, then do not force yourself to fast. Restricting yourself unrealistically is pointless – it’s not worth it if it makes you unhappy. There are 2 basic terms we need to understand here first: feeding and fasting. Your body is in a feeding state when you are eating your food, and you are in a fasting state when you are between your meals. The Approach Skipped meals. This is when you skip over a meal to induce extra time of fasting. Usually people choose breakfast, but others prefer to skip lunch. Eating windows. Usually this condenses your entire macronutrient intake between a 4 and 7 hour window. The rest of the time you are in a fasting state. 24-48 hour cleanse. This is where you go into extended fasting periods, and do not eat for 1-2 days. I don’t recommend that you go straight for a 1-2 day fast, but begin by restricting you Continue reading >>
5 Day Water Fast Results (self Experiment)
I’m not a fan of cancer. The only people I’ve lost in memory – my grandfather and other close family – it was cancer that took them. NOT putting an end to the fun of life because of cancer has been a part of my plan since my early 20s. So after my discussion with Dr. Thomas Seyfried in episode 16 I was looking forward to put his 5 day water fast “cancer insurance policy” to work. As I read into the details to start planning my prolonged fast what I found convinced me even more this was something I had to do soon. Maybe what I discovered would inspire you to try a 5 day fast soon too? Fasting for Reasons Beyond Cancer Since getting bitten by a tick in Phuket, Thailand a few years ago I’ve been fighting some chronic health issues. I discovered that it’s probable that these are at least in some part due to lyme disease and babesiosis infections I only got documented earlier this year (and thus had never been treated for). It bears mentioning, since there’s a fair amount of non-rigorous and dubious material on the internet on the subject of lyme disease in particular, that this was documented via the IgM/ IgG labs, and met CDC criteria. What does this have to do with fasting? It comes down to this: Having a stronger immune system gives you a better chance of eliminating lyme. Since in cases like mine where it was not treated in the early stages it seems to be relatively tricky and long-winded to get rid of. I’ve made it a rule to collect and put into practice anything that improves the odds of a quicker recovery. And… fasting is a potential new tool to speed up recovery. Valter Longo, Director of the USC Longevity Institute, has published a large number of studies on fasting and caloric restriction and their application to treat disease and enhance agi Continue reading >>
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 >>
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 >>

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 >>
The Effects Of Fasting Ketosis
Understanding ketosis and muscle loss during fasting. The process of ketosis is one of the physiological effects of fasting in which the brain (and some other bodily processes) uses ketones produced from fatty tissues as a fuel instead of the usual glucose. This is called "muscle sparing". When glucose isn't readily available via the diet (in the form of carbohydrates) and the glycogen stores in the liver become depleted, the body could break down muscle to get it. But ketosis is an adaptation that will spare muscle during times of shortage by instead breaking down fat stores and manufacturing ketones for brain fuel. It is said this state is attained at approximately 48 hours of a water fast for women and closer to 72 hours for men. The effects of fasting ketosis have become a more popular and controversial subject in recent years due to low-carb, high-protein dieters relying on it long-term to "burn the fat". Where ketosis was once considered a "crisis response" of the body and fine only for short durations, there are some doctors who now contend ketones are an acceptable alternative fuel, produced and used by the body any time glucose is scarce, which can happen even in non-fasting, non-dieting individuals, such as during intense exercise or during sleep. They are considering it a natural metabolic process where ketone production and use fluctuates constantly in response to the body's needs. What is so controversial about the low-carbers use of ketosis is the long term, artificially produced, use of it. Over long periods of time, their high-protein diet produces excess protein by-products that become a strain on the kidneys to eliminate. Ketosis also creates a mild acidosis of the blood, which, over a long period of time is considered detrimental to our health. One ef Continue reading >>
What Everybody Ought To Know About Ketosis
Recently I wanted to explore the world of Ketosis. I thought I knew a little bit about ketosis, but after doing some research I soon realised how wrong I was. 3 months later, after reading numerous books, listening to countless podcasts and experimenting with various diets I know have a sound understanding of ketosis. This resource is built as a reference guide for those looking to explore the fascinating world of ketosis. It is a resource that I wish I had 3 months ago. As you will soon see, a lot of the content below is not mine, instead I have linked to referenced to experts who have a greater understanding of this topic than I ever will. I hope this helps and if there is something that I have missed please leave a comment below so that I can update this. Also, as this is a rather long document, I have split it into various sections. You can click the headline below to be sent straight to the section that interests you. For those that are really time poor I have created a useful ketosis cheat sheet guide.

Not to be confused with Ketoacidosis. Ketosis is a metabolic state in which some of the body's energy supply comes from ketone bodies in the blood, in contrast to a state of glycolysis in which blood glucose provides energy. Ketosis is a result of metabolizing fat to provide energy. Ketosis is a nutritional process characterised by serum concentrations of ketone bodies over 0.5 mM, with low and stable levels of insulin and blood glucose. It is almost always generalized with hyperketonemia, that is, an elevated level of ketone bodies in the blood throughout the body. Ketone bodies are formed by ketogenesis when liver glycogen stores are depleted (or from metabolising medium-chain triglycerides). The main ketone bodies used for energy are acetoacetate and β-hydroxybutyrate, and the levels of ketone bodies are regulated mainly by insulin and glucagon. Most cells in the body can use both glucose and ketone bodies for fuel, and during ketosis, free fatty acids and glucose synthesis (gluconeogenesis) fuel the remainder. Longer-term ketosis may result from fasting or staying on a low-carbohydrate diet (ketogenic diet), and deliberately induced ketosis serves as a medical intervention for various conditions, such as intractable epilepsy, and the various types of diabetes. In glycolysis, higher levels of insulin promote storage of body fat and block release of fat from adipose tissues, while in ketosis, fat reserves are readily released and consumed. For this reason, ketosis is sometimes referred to as the body's "fat burning" mode. Ketosis and ketoacidosis are similar, but ketoacidosis is an acute life-threatening state requiring prompt medical intervention while ketosis can be physiological. However, there are situations (such as treatment-resistant Continue reading >>
Quick Start Keto
Low carbers know ketosis is the superhero of fat-burning. But what is ketosis? And how do you get into ketosis quickly? Keto FAQs and why it makes a difference in fat loss. 6 techniques to get into ketosis fast 3-Day rapid reach ketosis technique Try a few rapid keto techniques and eat specific low carb keto foods. Our quick start guide covers everything you need to reach ketosis fast. If carbs are limited to small amounts in your diet, your body relies on fat for energy. When you reach ketosis, fat burns rapidly and muscle tissue is spared. Why Does Keto Burn Fat Faster? To get into ketosis you’ll avoid sugar, leading to low insulin levels. Low insulin curbs hunger and accelerates fat-burning. Metabolizing fat and producing ketones burns more energy than metabolizing carbs. The result is a much higher calorie burn. How Do I Reach Ketosis? Ketosis happens when carbs are very low – usually when eating 20 to 50 grams of net carbs or less per day. (Carb grams from fiber are NOT counted in daily totals.) Everyone is different. Some low carbers must eat very low carb to reach ketosis. Typical Keto Ratio Getting into ketosis requires eating meals that are high in healthy fats and low in carbs. Protein grams should not exceed 20 % of total daily calories. Keto Calculator This free online keto calculator determines your ideal nutrient ratio for weight loss or maintenance during ketosis. The keto calculator recommends the optimum daily calories, fat, carb and protein amounts to help you get into ketosis – and meet your weight loss goal. How to Know You’re in Ketosis Keto Symptoms During keto, low carbers experience bursts of energy and heightened mood – just two of the big benefits of ketosis. Some dieters notice a temporary, sweet taste in the mouth or a mild, sweet b 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 >>
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 >>
