Why The Author Of 'the 4-hour Body' Doesn't Eat For 72 Hours At A Time
Tim Ferriss has a strict fasting regimen. Andrew "Drew" Kelly Bestselling author and star podcast host Tim Ferriss undergoes a monthly three-day fast in addition to longer supervised fasts. He said the habit makes him feel physically and mentally refreshed. There is established research showing that intermittent fasting is proven to be effective for weight loss, and emerging research suggesting it can slow cell aging. With the publication of "The 4-Hour Body" in 2010, Tim Ferriss embraced his role as a self-proclaimed "human guinea pig." He took a long-held interest in athletic training and nutrition and put it through the lens of his hit book "The 4-Hour Workweek," experimenting with different workout regimens and diets based on research and drawing his own conclusions. This love of undertaking often extreme physical experiments has continued, and one of his latest interests has been intermittent fasting. Business Insider recently spoke with Ferriss about his latest book, "Tribe of Mentors," and he explained why he undergoes a monthly three-day fast, with additional longer, supervised fasts. Note that Ferriss was adamant that you shouldn't try any aspects of his regimen without asking your doctor about it, and that even short fasts should not be done carelessly. The benefits of fasting People have been consciously fasting for thousands of years for spiritual discipline and, increasingly so over the last several years, fasting intermittently for perceived health benefits. Ferriss is interested in the discipline of fasting, but is primarily focused on the latter aspect. The latest research into the practice of controlled intermittent fasting concludes that it is a safe and effective method for weight loss (stress on "controlled"; it's not recklessly starving oneself), an Continue reading >>
January Water Fast: What I Ate After Fasting And How Much Did I Gain?
It’s been just about 50 hours since I ended my 12 day January Water Fast. (my fast ended on Saturday morning, right now it’s Monday morning) I’ve actually learned so much about my body and my eating habits in such a short period of time that it’s astonishing. First of all – I sincerely love food and even more so love to cook. My kitchen is my happy place and I’m totes happy to be cooking/eating again. However, Eating 3 meals on Saturday was just way too much food. When you complete a water fast the most important aspect to ensure you don’t regain the weight you lost, is to not return to the same eating style you had before your fast (if you weren’t eating healthily) Ray & I are eating low-carb/high-fat in order to maintain our ketogenic state (i.e. fat burning machine. While many people say that you need to end a water fast with soft foods, we took a less traveled path of eating real food. And it was a huge success. Between Ray & I we were on both ends of the spectrum when it comes to digestion — for some it moves a little fast and some it moves a little slow (at the request of my hubby I won’t get into specifics but I’m sure you get my drift) We didn’t feel sick or nauseated – only overfull since undoubtedly our stomaches shrunk in 12 day w/o eating – so any quantity of food would make us feel extra full. And we consciously realized that going forward we need to adjust the way we fill our plates, eating less quantity overall. A secret to keep your portions under control is to use smaller plates – the plates in all of these pictures aren’t full size they are large salad plates. Saturday – 25 g net carbs 9 am Breakfast: 2 Scrambled Eggs, Canadian Bacon, Asparagus, Raw Butter & Sauerkraut – 3g net carbs 1 pm Lunch: cottage cheese, olive Continue reading >>

The Ultimate Alpha’s Guide To Intermittent Fasting
When I first heard about intermittent fasting, just because the phrase included the word “fasting” – my immediate reaction was to dismiss it. I’ll be honest – I’m not a big fan of fasting in general. I feel like the majority of fasts are either too heavily influenced by religious beliefs with no regard to health benefits or hazards, or are too esoteric and “woo-woo” and bear very little connection to real science behind them. Religious or spiritual fasts are often aimed at achieving a specific state of mind (with no regard to what this does to your body). They restrict the wrong kind of foods (most partial religious fasts restrict animal fats and protein, while being very lenient with simple carbs) or restrict too much for too long (which also deprives your body of important minerals and nutrients and leads to the breakdown of healthy tissue in an attempt to survive). In terms of non-spiritual dietary fasting – there is just not enough consistency among different protocols. Some allow liquids (usually water, but a few offer other exotic options, such as various juices, etc.) and some do not. Some only exclude a specific class of food and some restrict all of them. Some may seem like an attempt to improve health, but utilize some esoteric concepts behind them, like “cleansing” (which, I despise because of all the misinformation surrounding it). And a large number of fasts are just poorly designed dietary fads, relying too heavily on the “novelty factor” and marketability. But as I explored scientific evidence behind intermittent fasting and experimented trying to see what works best, I have made some interesting discoveries and my attitude started changing. While personally I still would not advocate long- or even medium-term fasting (at least n 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 Science Of Fasting: Can You Lose Weight By Not Eating?
Find out whether not eating to lose weight actually works or if it does more harm than good: With peoples love for food continuously increasing and the ‘junk’ food industry continuously innovating, who is not worried about getting fat? Women aren't the only ones who are conscious about their figure; men not only wish to lose the excess fat but also want to gain that athletic physique as well. However, few are ready to make the sacrifices needed to make that happen. There are a lot of new types of diets today such as Paleo, Raw Vegan, and Ketogenic among many others. Even though they differ in many ways, they equally highlight the cry from people - "I want to lose weight". The problem with some of these diets is that they may just be a fad and not actually based on any real science. This could potentially put your health at risk. New types of diets often lack research to back their claims and in worse cases they might even lead to certain vitamin or mineral deficiencies. That is why it is much safer to opt for those that have overcome the test of time, such as fasting. If you feel uncertain about what to eat for weight loss, not eating at all to lose weight might be the answer you’re looking for! What is fasting? Related: Does the "Eating One Meal a Day Diet" work? Fasting is a practice you can find in many religions and has existed for many centuries. It is simply the practice of refraining from eating some or any food for a period of time. Water fasting is the most common since humans cannot live without water for too long, however we can live without food as long as we still have fat on our bodies. When you water fast, it means you only drink water. You don't eat anything. You can do this in either of the following two ways: #1: Long term fasting Long term fasti Continue reading >>

Ketosis Vs. Intermittent Fasting
Ketosis and intermittent fasting are topics that often fall into the same types of conversations. That being said, they do have differences that can lead you to wonder if one’s better than the other or how both can fit into your life. We can help you there! We’ll be comparing ketosis vs. intermittent fasting — starting with a summary of each, then seeing what they have in common and how they differ. What is Ketosis? In short, ketosis is the process where the body burns ketone bodies for energy. With a regular type, the body’s primary source of energy is glucose, which comes from eating carbohydrates like bread, sugars, grains, fruit, or beans and legumes. The carbohydrates from these foods are either used as glucose by the body immediately or stored as glycogen to be used later. However, if the body has a low supply of glucose, it must turn to something else for fuel. In the case of ketosis, that’s fat. A ketogenic diet, which is high-fat, moderate-protein, and very-low-carb, will cause the body to break down fat instead of carbs for energy. When this happens, the follow ketone bodies are formed: Acetoacetate: Created first and then either converted into beta-hydroxybutyrate or turned into acetone. Acetone: Created spontaneously from the breakdown of acetoacetate. It’s the most volatile ketone and is often detectable on the breath when someone first goes into ketosis. Beta-hydroxybutyrate (BHB): The ketone most often measured in blood tests and found in exogenous ketones like Perfect Keto. There are many benefits of putting the body into a state of ketosis, the most popular being weight loss, which we’ll examine first. Ketosis Weight Loss Benefits Ketosis helps weight/fat loss for the following reasons: Other health benefits of ketosis include: Studies sho Continue reading >>
Dr. Osborn: How Does Intermittent Fasting Affect The Ketogenic Diet?
“Let’s talk intermittent fasting for a second and then discuss the interplay between both of these entities. Intermittent fasting, a variation of Ori Hofmekler’s Warrior Diet, popularized more than 20 years ago (despite claims that it is actually “new science”), is founded on once or twice daily feedings punctuated by long periods of fasting (18 hours daily or thereabouts). This is thought to emulate our primitive eating habits that were sporadic, and in short bursts, as dictated by the food supply. If we killed, we ate. Else we fasted. It is speculated, by virtue of such patterned, intermittent feedings, unlike the grazing style of modern man, that disease incidence was lower and that absent infection, human life expectancy would have exceeded that of today. Why? This likely has to do with lowered insulin signaling because let’s face it, diseases of modern man are the result of metabolic dysregulation due to overconsumption of carbohydrates, the resultant insulin resistance and heightened bodily inflammation: accelerants of the aging process. So there certainly is merit to this philosophy, at least as an isolated dietary modality. Personally, I have an issue combining intermittent fasting with a ketogenic diet. Why? Metabolic slowdown. Sure, one can make the case for the on switching of tumor suppressor genes in the fasted state, however, I am equally as concerned about the potential loss of muscle mass when these two modalities are combined. It is very difficult to maintain muscle on an intermittent fasting regimen to begin with, because the fasted state (particularly in the context of depleted glycogen stores) induces muscle catabolism for gluconeogenesis. Yes, ketones have anti-catabolic effects, however they tend to be overridden by bodily demands, one Continue reading >>
7 Tips To Get Into Ketosis
Ketosis is a normal metabolic process that provides several health benefits. During ketosis, your body converts fat into compounds known as ketones and begins using them as its main source of energy. Studies have found that diets that promote ketosis are highly beneficial for weight loss, due in part to their appetite-suppressing effects (1, 2). Emerging research suggests that ketosis may also be helpful for type 2 diabetes and neurological disorders, among other conditions (3, 4). That being said, achieving a state of ketosis can take some work and planning. It's not just as simple as cutting carbs. Here are 7 effective tips to get into ketosis. Eating a very low-carb diet is by far the most important factor in achieving ketosis. Normally, your cells use glucose, or sugar, as their main source of fuel. However, most of your cells can also use other fuel sources. This includes fatty acids, as well as ketones, which are also known as ketone bodies. Your body stores glucose in your liver and muscles in the form of glycogen. When carb intake is very low, glycogen stores are reduced and levels of the hormone insulin decline. This allows fatty acids to be released from fat stores in your body. Your liver converts some of these fatty acids into the ketone bodies acetone, acetoacetate and beta-hydroxybutyrate. These ketones can be used as fuel by portions of the brain (5, 6). The level of carb restriction needed to induce ketosis is somewhat individualized. Some people need to limit net carbs (total carbs minus fiber) to 20 grams per day, while others can achieve ketosis while eating twice this amount or more. For this reason, the Atkins diet specifies that carbs be restricted to 20 or fewer grams per day for two weeks to guarantee that ketosis is achieved. After this point, s Continue reading >>
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 >>
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 >>
Searching For Your Soul Mate Diet? Find Out If Keto Or If Is Right For You
Waffling between trying out intermittent fasting or the ketogenic diet? First of all, put down the waffle, because they aren't on the menu for either of these popular diets. Sorry. But now that we've got your attention, let's get down to business. The ketogenic diet and intermittent fasting have pretty much taken over our collective news feeds at this point, and for good reason. They've both been touted for their ability to help people drop weight without restricting calories, improving blood sugar, cholesterol, and blood pressure numbers. The perks sound similar, but these diets differ in how they work and who should be using them. We're breaking down the ins and outs of both diets, as well as how to determine if either of these may be right for you. What Is the Ketogenic Diet? The ketogenic diet, or keto, is all about getting your body into the fat-burning state of ketosis. Basically, by shifting your calorie intake to high-fat, moderate-protein, and very low-carb, your body stops burning glucose for energy and begins burning ketones. This allows your body to turn to stored fat for fuel instead of the sugar in your morning bowl of Froot Loops. The benefits of being in ketosis, according to Jimmy Moore (he literally wrote the book on keto) include better sleep, stable blood sugar, reduced inflammation, improved blood pressure and cholesterol, clearer memory and cognitive function, better recovery from exercise, and maybe even clearer skin. How Does the Ketogenic Diet Work? When we say low-carb, we mean low-carb. If you go this route, you'll be forgoing bread and pasta and replacing them with high-fat foods like avocado, beef, coconut oil, and cheese. It's not all burgers and bacon, though. You'll also be loading your plate with lots of low-starch veggies like greens, t 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 >>
Intermittent Fasting And Keto
Fasting seems to be what everyone is talking about nowadays and I am sure you are wondering what it is, how it works and what you need to do. ‘Fasting’ is a simple concept where you eat all your food for the day in a small window of time. You essentially go for a period of time without eating, when you wake up after a seven or eight-hour nightly sleep, you are waking up in a fasted state. All you need to do is extend the amount of time before you eat your first meal for another seven or eight hours, bringing you to a total of about 16 hours. Then, you eat all your food in the last eight-hours of your day. Don’t worry, there are many different types of fasting and this can be done in the reverse order as well! Fasting has many benefits such as: Reducing your appetite, while increasing your mental clarity and energy. In conjunction with a Ketogenic Diet it can elevate your ketone levels, which your body will rely on for fuel Simplifies your day in terms of meal planning and meal timing. Just imagine not having to worry about what you’re going to eat for half the day! Studies have shown fasting reduces insulin levels and can improve insulin resistance Patients suffering from asthma showed a significant reduction in inflammatory markers. Used to treat rheumatoid arthritis, through reducing inflammation Helps treat hypertension by reducing systolic blood pressure Lastly, it can tap into your fat stores to improve weight loss by increasing your body’s fat oxidation, meaning through fasting, your body increases the hormones that burn fat and reduces the hormones that inhibit fat burning Here are a couple different ways of fasting: Alternate Day Fasting: Go a full day without eating, which is roughly 36 hours (9pm until 9am, the following day) Intermittent Fasting: Go Continue reading >>
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 >>
