What Is Fasting Ketosis?

The Perks Of Fasting, With None Of The Work

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 >>

How To Get Into Ketosis Fast | (7 Keto Hacks) To Enter Ketosis Quickly

How To Get Into Ketosis Fast | (7 Keto Hacks) To Enter Ketosis Quickly

How To Get Into Ketosis Fast The biggest question I get is how to get into ketosis fast? When I first started my ketogenic lifestyle two years ago, I was just trying to lose weight “period”. I didn’t understand being in a state of nutritional ketosis let alone being fat adapted. For those reasons, I failed miserably trying different types of the ketogenic diet like CKD (Cyclic Keto Diet). It was painful eating low carb during the week because all I could think about was refeeding on the weekend. Was it because I was doing it wrong? Or maybe I shouldn’t be doing it at all…Hmmm It seemed like every Monday and Tuesday I was experiencing keto flu all over again…lol… It was horrible repeating that week after week. Basically, if I was reaching ketosis by the end of the week, I was kicking myself out of it come the weekend! But like I said, I didn’t understand what ketosis was at the beginning stages so I had to learn the hard way. So I’m grateful you found this as I want to inspire you to give your all… Sorry about the rant… Let’s get down to the Dirty! When you’re in a state of ketosis your liver oxidizes fat into energy molecules that the brain then utilizes as fuel. To be in ketosis you have to be producing 0.5 mmol/L – 5.0 mmol/L of ketones which you can test using a glucometer. Below I’m going to give you some tips that have helped people that I’ve worked with get into ketosis fast. Get to Bed Early Sleep is the most important factor on a ketogenic diet because this is when the body produces the most ketones. Basically, you body repairs at night from releasing growth hormones. Here are a few reasons to get to sleep on time… 1: You don’t want high cortisol levels at night because it can cause an inflammatory state and spike your glucose Continue reading >>

Intermittent Fasting While In Ketosis As Beneficial?

Intermittent Fasting While In Ketosis As Beneficial?

I am about 3 weeks into a ketogenic diet, following the framework outlined by Volek and Phinney in their books. They recommend that protein is a set amount based on your height and ideal body weight. For me this is around 90g per day minimum. Carb intake is minimized, and for me its less than 20g net carbs (Atkins calculation) per day. Based on this approach, the rest of my energy needs come from fat. If I am active, I eat more fat. The protein and carbs remain consistent as total amounts, not % based. I have been monitoring blood ketones twice daily and have been in the recommended range for some time now. I may not be fully keto-adapted yet (as they say it can take 4-6 weeks), but I am definitely generating enough ketones to provide adequate fuel for my brain and other organs once my body does largely adapt. On the 'Ask the Low Carb Experts' podcast a few months ago, Jimmy Moore had Dr. Phinney on the show. It was a long show with a ton of great info, but there was one thing that Phinney said that didn't make sense to me and he didn't really explain. What he said was that fasting is a bad idea because one will lose lean mass when not eating for an extended period of time. He said skipping lunch might be OK, but he wouldn't recommend going longer than that. There was no real further explanation or discussion on the topic. Since the context of this show was ketogenic diets, I am under the impression he was speaking of fasting while in ketosis. Alas, I could not tell if his statement was general or specific. Many people here are familiar with the Lean Gains (18/6) and the Eat Stop Eat approaches, in which you have fasting windows of 18-24 hours, but never actually have an entire day where you do not eat (well for most people most of the time). There are many supposed ben Continue reading >>

Dr. Group’s Ketogenic Fast For Rapid Weight Loss

Dr. Group’s Ketogenic Fast For Rapid Weight Loss

Maintaining a healthy body weight is one of the best ways to support your overall health. Excess body fat increases your susceptibility to serious conditions like type II diabetes, high blood pressure, stroke, heart disease, sleep apnea, fatty liver, cancer, and joint problems.[1] Many fat-loss fads, diets, and pills come and go, and very few yield lasting results. Adopting a ketogenic diet is one strategy for losing fat that’s tried, tested, and proven effective. Knowing this, I began my research into improving the typical ketogenic diet. People who are familiar with my work know that I’m always trying new cleanses, detox programs, and diet plans in my ongoing quest to discover new ways to improve my health. I kept coming across the many benefits of fasting, and I thought, “Why not combine principles of fasting with the best elements of a ketogenic diet and enjoy the best of both?” What Is a Ketogenic Diet? A ketogenic diet is a diet that provides fat and protein, but few or no carbohydrates. The body prefers glucose and glycogen, both derived from carbohydrates, as its primary source of fuel and it generally operates in a sugar-burning state known as glycolysis. Depriving the body of carbohydrates, however, forces it to use stored fat for energy. This special fat-burning mode, known as ketosis, quickly burns through fat reserves. It takes about 24-36 hours to completely burn through the glycogen stored in the muscles and liver. The catch? The body tells the brain to refuel on carbohydrates when blood sugar dips. In other words, your appetite kicks in and you feel hungry. This physiological response makes it a challenge for many people to adhere to a ketogenic diet long enough to enter ketosis. What Is Fasting? Fasting means avoiding food for longer stretches o Continue reading >>

Juice Fasting For Ketosis

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 >>

Are There Different Types Of Ketosis?

Are There Different Types Of Ketosis?

Before reading this, if you haven’t already, I suggest reading What is a Ketogenic Diet and Understanding Ketosis so you will have a stronger understanding of what it means to be in a state of ketosis. The next step necessary in comprehending the ketogenic diet is learning the different types of ketosis that can occur. For this article, we will refer to three different forms of ketosis: fasting ketosis, nutritional ketosis, and pathological ketosis. The different types of ketosis vary in their degree of ketone production as well as their method of induction. Fasting Ketosis The idea of fasting has been around for hundreds of years and played a major part in the origins of the ketogenic diet. In fact, many great philosophers, such as Hippocrates, Socrates, and Aristotle, all praised the many benefits of fasting. Paracelsus, physician and father of toxicology, was quoted saying, “Fasting is the greatest remedy—the physician within.” While these early scientists and philosophers were definitely ahead of the game in recognizing the potential of fasting, the mechanisms were still yet to be understood. Ketosis tends to occur when insulin and blood glucose levels decrease to an extent that allows for increased fat oxidation, which is ultimately followed by greater ketone production. A minor state of ketosis can occur following periods of complete food restriction, such as an overnight fast. This may produce ketone levels around 0.1 mmol/L to 0.03 mmol/L. Shorter duration fasts typically will not raise ketone levels above these levels because the rate of ketone metabolism matches ketone synthesis. As the fast continues, the rate of ketone production exceeds ketone clearance, resulting in an increase in blood ketone levels (1). While a minor state of ketosis can occur du Continue reading >>

Keto And Intermittent Fasting: “i Am Completely Blown Away By The Changes”

Keto And Intermittent Fasting: “i Am Completely Blown Away By The Changes”

Christine has completely transformed her health in only one year with a keto diet and intermittent fasting. Here she shares all the benefits and what it has been like ditching carbs: Dear Dr. Eenfeldt, I never in a million years thought that I would share my story, but after a very emotional weekend looking at this year-old picture, and lots of encouragement, I am sending it along. The picture I am sending is one year apart – from a very unhealthy, metabolically sick 49-year old transformed to a healthy, energetic 50-year old. I am completely blown away by the changes. In October 2016, I had been on a “quitting sugar” journey for a few months and had successfully given up the white, sweet stuff. Desserts, cookies, and packaged foods were no longer part of my diet but was resulting in a very slow weight loss. I started this journey to lose weight, and to reverse metabolic syndrome, fatty liver, insulin resistance, and if I was very lucky, sleep apnea. I was complaining about the slow loss to a friend and she asked me if I was familiar with the work of Dr. Fung. I had never heard of him or of the LCHF/keto way of eating. On that day, January 13, 2017, I came home and scoured the internet for info. The first source of information was your wonderful website. I spent ALL weekend on your website just soaking it all in. I truly appreciate all the educational videos and the testimonials. January 13, 2017 was the last day I ate potatoes, bread, and pasta. Those were the final high-carb foods that I kicked to the curb – and as a result, I had excellent results with weight loss. Because I had already quit sugar, there was little difficulty or withdrawal – I’m pretty sure I entered a ketosis state within a week of ditching those high-starchy carbs. Nine months on the LC Continue reading >>

The Results Of My Four Day Fast To Start A Ketogenic Diet

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 >>

What A Fasting Diet Can And Can't Do For Your Health

What A Fasting Diet Can And Can't Do For Your Health

Google “fasting for health” and you’ll get more than 6.3 million hits, ranging from doctors who recommend it for treating a range of diseases, to spas that promise detoxifying food-free vacations, to bloggers who say that fasting makes them feel clearer mentally and more fit — and, increasingly, to fitness professionals touting diets that incorporate fasting as a method for weight loss. But does medical research actually support those claims? Every day, organs such as the liver, kidney, and spleen work to remove and neutralize toxins from the body to keep our cells healthy, says David Katz, MD, MPH, director of the Yale-Griffin Prevention Research Center at Yale University in New Haven, Connecticut. “When you fast, you eliminate input of additional toxins from food,” Dr. Katz says — “and there is a potential biological benefit to that.” “Potential” is the key word. While a growing body of research suggests intermittent fasting may have health benefits, much of the evidence is far from conclusive, and there are still a lot of unknowns about how a fasting diet or intermittent fasting diet might affect our bodies, particularly over the long-term. How Intermittent Fasting Diets Work Fasting, or intermittent fasting diets, shift the focus from what you’re eating to when you’re eating. It’s not about restricting calories for days on end, but rather it’s about eating for a prescribed number of hours a day, or a certain number of days per week, and then abstaining or limiting food consumption for another period of time. For example, the Fast Diet, also known as the 5:2 diet, advocates for eating what you want for five days of the week (without too much thought to calorie intake), and restricting calorie intake to 500 calories for women and 600 for Continue reading >>

Bulletproof Intermittent Fasting: Lose Fat, Build Muscle, Stay Focused & Feel Great

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 >>

The Effects Of Fasting Ketosis

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 >>

Complete Guide To Intermittent Fasting

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 >>

Keto + Intermittent Fasting: The Ultimate Fat Loss Program

Keto + Intermittent Fasting: The Ultimate Fat Loss Program

Summer is just around the corner, and that means it’s time to end the bulking season and enter full on fat loss mode. It’s a task that’s not always easy or all that enjoyable, but the results are certainly worth it come beach season. There’s a ton of information out there on how to get shredded, but none quite like what we’ve developed here. Previously we’ve covered one of the newest and most effective eating protocols around in Intermittent Fasting. And while that can be great for weight loss, when it’s combined with a ketogenic diet, the two will get you shredded like never before. What is Keto? The ketogenic diet, a.k.a. “keto”, is an extremely low carb diet that places a premium on fat intake (as much as 75-90%!) along with a moderate protein intake. There have been a number of keto diets circulating around the fitness industry in recent years as the diet has grown in popularity, but to “standard” ketogenic diet consists of the following macronutrient breakdown: 75% Fat 20% Protein 5% Carbohydrate The benefit of substantially reducing carbohydrate intake forces your body to enter ketosis - a metabolic process stimulated when carbohydrates are severely restricted. This essentially “shifts” your body from a glucose fueled machine, to a fat fueled one that generates ketones. Ketones are synthesized when a person doesn’t consume ample carbohydrates to provide the body with adequate glucose (sugar) to run the required metabolic processes. Upon entering a ketogenic state, the body becomes significantly more efficient in utilizing stored fat for energy. Some may worry that such a drastic reduction in carbs may affect neurological function, as the brain runs on glucose, but don’t worry, a metabolic process called gluconeogenesis can synthesize Continue reading >>

Tim Ferriss – 3 Day Fast Protocol Details – Get Into Ketosis Quicker And Easier

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 >>

Autophagy: The Real Way To Cleanse Your Body

Autophagy: The Real Way To Cleanse Your Body

For the last time, forget juice cleanses and detox diets. They’re fluffy nonsense words. While there’s probably nothing wrong with drinking your weight in liquid kale, it won’t flush out toxins any faster than if you were eating, you know, actual food. The good news: There's a little-known way your body does cleanse itself, and it’s a process that you can control. All you need to do is practice a little self-cannibalism. What? Yes, you can actually train your body to eat itself—and believe it or not, you want it to. It's a natural process called autophagy (literally “self-eating”), and it’s the body’s system of cleaning house: Your cells create membranes that hunt out scraps of dead, diseased, or worn-out cells; gobble them up; strip ’em for parts; and use the resulting molecules for energy or to make new cell parts. “Think of it as our body’s innate recycling program,” says Colin Champ, M.D., a board-certified radiation oncologist, assistant professor at the University of Pittsburgh Medical Center, and author of Misguided Medicine. “Autophagy makes us more efficient machines to get rid of faulty parts, stop cancerous growths, and stop metabolic dysfunction like obesity and diabetes.” There’s also evidence that the process plays a hand in controlling inflammation and immunity. When scientists engineer rats that are incapable of autophagy, they’re fatter, sleepier, and have higher cholesterol and impaired brains. To sum it up, autophagy is key to slowing the aging process. And you can learn how to do it better. 3 Ways to Self-Destruct "So how do I eat myself?” is a question you probably haven’t asked before, but we’re about to tell you. First of all, autophagy is a response to stress, so you’re actually going to want to put your Continue reading >>
