Fasting To Induce Ketosis

Human Brain Beta-hydroxybutyrate And Lactate Increase In Fasting-induced Ketosis.

Human Brain Beta-hydroxybutyrate And Lactate Increase In Fasting-induced Ketosis.

Abstract Ketones are known to constitute an important fraction of fuel for consumption by the brain, with brain ketone content generally thought to be low. However, the recent observation of 1-mmol/L levels of brain beta-hydroxybutyrate (BHB) in children on the ketogenic diet suggests otherwise. The authors report the measurement of brain BHB and lactate in the occipital lobe of healthy adults using high field (4-T) magnetic resonance spectroscopy, measured in the nonfasted state and after 2- and 3-day fasting-induced ketosis. A 9-mL voxel located in the calcarine fissure was studied, detecting the BHB and lactate upfield resonances using a 1H homonuclear editing sequence. Plasma BHB levels also were measured. The mean brain BHB concentration increased from a nonfasted level of 0.05 +/- 0.05 to 0.60 +/- 0.26 mmol/L (after second day of fasting), increasing further to 0.98 +/- 0.16 mmol/L (after the third day of fasting). The mean nonfasted brain lactate was 0.69 +/- 0.17 mmol/L, increasing to 1.47 +/- 0.22 mmol/L after the third day. The plasma and brain BHB levels correlated well (r = 0.86) with a brain-plasma slope of 0.26. These data show that brain BHB rises significantly with 2- and 3-day fasting-induced ketosis. The lactate increase likely results from ketones displacing lactate oxidation without altering glucose phosphorylation and glycolysis. Continue reading >>

But the great thing about following a ketogenic diet is that you can eat until your heart—er, stomach—is content. You just have to eat enough of the right foods. And, of course, eat very little of the wrong foods. Is getting into ketosis safe without a doctor? Before reviewing how to get into ketosis quickly, let’s take a look at a quick background: T Continue reading >>

How To Get Into Ketosis In 24 Hours: Practical Tips And Tricks

How To Get Into Ketosis In 24 Hours: Practical Tips And Tricks

Some people need to be in ketosis for medical reasons while others need to be in a fat-burning mode for athletic competitions. Whatever the reason, I’ve conjured up tips on how to get into ketosis in 24 hours. Before I begin… These tips are purely from experience. While a lot of it has been backed by research, always take things with a grain of salt. There is no one size fits all diet that will turn you into superman. Anyways.. When I first adopted the low carb high fat keto lifestyle a couple years back, I became obsessed with it. To me it felt like I just struck a goldmine. It felt like some sort of esoteric subculture that no one knows about and those that do, have a leg up on their competition. With this newfound obsession, I spent hours on researching, implementing, and documenting how to get into ketosis as fast as possible. The science is out there. Study after study showing how beneficial being in ketosis is. Through trial and error, I’ve conjured up these tips on how to get into ketosis in 24 hours. Some of it is probably obvious and common sense but that doesn’t mean it isn’t effective. Starting Tips On How To Get Into Ketosis In 24 Hours Start Intermittent Fasting (IF) I’ve mentioned it in a previous post, here. Intermittent fasting is like peanut butter and jelly, like batman and robin, like a fork and spoon, like Hillary Clinton and Donald Trump (just kidding). But seriously. By prolonging the time in which you eat your first meal, your body begins to enter a fat-burning stage (ketosis). I emphasize intermittent fasting with the ketogenic diet because it speeds up the whole process in depleting your glycogen storages. My recommendation is to skip breakfast completely. A popular protocol that many people praise is the 16:8 hour fast. This means y Continue reading >>

Quick Start Keto

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 >>

How Long Does It Take To Get Into Ketosis?

How Long Does It Take To Get Into Ketosis?

Switching to a Ketogenic diet can be exciting, and you may be wondering how long it will be before you can expect to see results or ask “how long does it take to get into Ketosis?” This is perfectly normal, and almost everyone wonders the same thing when they switch to a low carb, high fat diet. The truth is, there is no one size fits all answer; it really does depend on who you are, what you eat, and how long it takes for your body to adjust. The good news is, for most people, this change takes place within a few days or weeks. Keep reading to find out how you can improve your body’s efficiency, and learn how to stay in Ketosis for the long-term. After all, it’s easier to stay in Ketosis once you’re there. How Do I Get into Ketosis? To answer your question of “how long does it take to get into Ketosis,” you must first ask “what is Ketosis” and “how do I get into Ketosis?” Let’s get started: Ketosis is a metabolic process and describes when the body uses fat for fuel. This occurs when there is a lack of glucose. As we generally eat a high carb, high sugar diet in the Western world, most people never enter Ketosis. Just because you lose weight does not mean you are in Ketosis, either, it just means you are eating a calorie deficient. When you switch to a low-carb diet and restrict your glucose, you might experience the Keto flu; these symptoms are your body learning to use fat as fuel, and signaling there is a change. For most people, this is a welcome change, but for other people, the transition takes a few weeks. It can even take a few people months to get into Ketosis, but this is usually because they are not following a strict Ketogenic diet. To get into Ketosis, you must: Eat less than 20g of carbs per day Restrict your intake of protein and Continue reading >>

Fast Ketosis: How To Enter Ketosis Fast And Start Burning Fat!

Fast Ketosis: How To Enter Ketosis Fast And Start Burning Fat!

Fast ketosis kick-starter to start burning fat immediately. Starting the keto diet, a common question that appears in your mind is “when is the ketosis is going to start?” Or “When does my body start to burn fat for fuel”. This is very important, because as soon as ketosis process starts you will begin to lose weight. Today I’m going to give you a step-by-step guide to fast ketosis induction! Doctor Atkins, the one who popularized the famous low-carb diet, suggested that if you reduce the intake of carbohydrates to less than 20 grams a day for about 7 days the ketosis will come to your life. This is very restrictive period and Doctor Atkins called it the induction phase [See: The Ultimate Ketosis Induction Phase Survival Guide]. During this restrictive phase, carbohydrates reserves in your body go down like mad. And when they achieve the needed point your body burns fat to produce energy. You can enter ketosis fast – much faster than 1 week! Food you should eat during a keto induction period must consist of animal protein, fat dairy products like country cheese, milk, butter etc. And don’t forget about eggs! Also, it would be good to add some leafy vegetables, such as spinach, cabbage and collards, or broccoli – but only in small amounts of half a cup per day. For oils, it is better to use medium-chain triglyceride oil [See: Everything you need to know about MCT Oil]. In addition to your salads use some coconut oil. It is very helpful. Another important thing on how to speed up a keto induction period is to increase the fat to 65% or more of your daily caloric intake. This is not an easy task to do, but it will bring you the result and it happens very soon. But, what really matters is to do some exercise. Choose which one you like, it could be dance or y Continue reading >>

how long would it take someone approximately to reach a state of ketosis after carbing up the night before and fasting the following day. for example: last night I consumed 250g carbs around 10pm, slept until 8am. that's 10 hours of fasting. say i extended this until 2pm that would equal 16 hours of fasting. would this be enough for a lot of people (if keto adapted) to re enter ketosis after the above mentioned glyocgen restoration of a couple hundred grams of carbs? thanks Lucas Continue reading >>

How To Get Into Ketosis Faster.

How To Get Into Ketosis Faster.

The shift from burning glucose to fat takes a long time. It depends on the individual and their degree of carbohydrate tolerance. Usually, the initial adaptation period will last about 2-3 weeks. There is also a way to get into ketosis fast within a few days. To get into ketosis several things have to be met. We need to have lower blood sugar and insulin levels for an extended period of time. Once insulin has been suppressed for some time, the pancreas will release its counter-hormone called glucagon. Its job is to deplete the liver glycogen stores and increase the fatty acid concentration in the blood stream. This will also lead to the production of ketone bodies by the liver. To satisfy its extremely high energy demands, the brain will begin to utilize fat for fuel. For this to happen, we have to either: Fast for a prolonged amount of time. Restrict our carbohydrate intake to a bare minimum. Both options are very effective ways of inducing ketosis. However, those two things aren’t always enough. Someone who is burning sugar may not ever be able to get into ketosis, despite following the guidelines. The body is just too addicted to sugar and enters an energy crisis. To provide energy for the brain and body, it is necessary to have a substitute for glucose. If you want to become fat adapted, then you have to promote the production of ketone bodies as well. Ketones are the third fuel source and are above glucose and even fatty acids. The outcome of burning the ketone body acetoacetate in the Krebs cycle creates 2 additional ketone molecules. Beta-hydroxybutyrate and acetone can create 25% more energy than pyruvate (sugar). This means that to get into ketosis faster we have to assist our body in producing more ketone bodies. To do that, we would have to consume fat that 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 >>

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 >>

Fasting And Ketosis Part Ii: Meal Timing

Fasting And Ketosis Part Ii: Meal Timing

The first article in the series, Ketosis and Fasting Part I: What Is Fasting and Why Do People Do It?, defines fasting and outlines some of the many purported benefits. This next segment explores different protocols for intermittent (under 24 hours) fasting. Meal Timing While prolonged daily fasting (24+ hours) has a host of other hormonal and metabolic benefits, many people incorporate shorter fasts into their daily routine by restricting the frequency of meals. Eating fewer meals per day can result in body fat loss, a decrease in cortisol levels, along with other interesting changes (Stote et al., 2007). Reducing meal frequency—intermittent fasting (IF)—allows for the benefits of fasting without requiring the individual to abstain from food for too long. One can both fast and feed within a 24-hour period, allowing for the best of both worlds. There are a number of popular protocols for IF. 16/8 Intermittent Fasting may be the most popular introductory protocol for IF. The “16” and “8” suggest that a person does not eat for 16 hours and then consumes all meals within the remaining 8 hours of the day. One way to do this easily is to skip breakfast. If the first meal of the day begins at 12 pm and the last meal is completed by 8 pm, then the fed window is 8 hours and the fasting window extends from 8 pm to 12 pm the following day. My personal variation is to eat each day between 12-2 pm and to finish my last meal by 6 pm most days (18/6 or 20/4 IF). The benefit of this approach is that the time spent sleeping counts towards the window during which a person fasts. Being asleep for 8 hours of a fast makes fasting much easier to do. The Warrior Diet (Hoffmekler, 2001) suggests that the faster allows 20 hours to pass between meals and then allows for a 4-hour eat Continue reading >>

5 Simple Steps To Get Into Ketosis

5 Simple Steps To Get Into Ketosis

I think almost everyone agrees with me when I say that the ketogenic diet is probably one of the most complex and difficult eating plans out there. Even when you’re not on a diet or trying to lose weight you still have to bring a lot of attention to detail. Getting into ketosis isn’t as important as we would think, but there are still 5 simple steps we can make to get into a ketotic state. What Needs to Happen The conditions of nutritional ketosis are: Low blood sugar levels (about <85 mg/dl) Low insulin And because of that there are going to be: Higher glucagon, which is released by the liver, in response to low insulin, to increase the amount of fatty acids in the blood stream. High serum blood ketone levels, with the optimal zone being in between 0.5 and 3.0 mMols. Here are the 5 simple steps to get into ketosis. Step #1 Do a 24-Hour Fast Ketosis is the by-product of a prolonged period of fasting. After your liver glycogen stores have been depleted already after an overnight fast, the liver then begins to create more ketone bodies. After 2-3 days of fasting, you’ll be definitely in ketosis. Your brain will adapt to using ketone bodies and gets about 75% of its energy from fat. Overall, the body’s glucose demands and protein catabolism get reduced to a bare minimum. However, to get into ketosis we don’t necessarily have to abstain from eating that long. We’re already in mild ketosis in the morning and doing a 24-hour fast will increase our ketogenic pathways by a significant amount. Step #2 Start Eating Low Carb Ketogenic Meals Once you finish your 24-hours, you can start eating keto foods. Make your first meal something extremely ketogenic, meaning: Ultra-low carbs – cruciferous vegetables, like spinach, kale, broccoli, cauliflower, cabbage, chard. Your 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 >>

The Beginners Guide To Ketosis: Investigating Low-carb, High-fat Eating

The Beginners Guide To Ketosis: Investigating Low-carb, High-fat Eating

The only hard and fast rule of health is that health is personal and what works well for one person may not work for someone else. Aside from that rule, there are “frameworks” that seem to benefit large groups of people. One more level down from that are alternative strategies that benefit smaller groups. Ketosis is likely one of those alternative strategies that works well for certain, smaller groups of people. So, right off the bat I want you to understand that Ketosis might not be for everyone. I’m going to lay out the case for potential benefits of Ketosis. If it sounds interesting and beneficial to you, then consider trying it. (see our free cheat sheet to help you). What is Ketosis Ketosis occurs when liver glycogen gets depleted and the body burns fatty acids for fuel. The primary driver of this state is a very low carbohydrate intake. Often, it also requires a low protein, higher fat intake. You can also achieve a state of ketosis by not eating altogether. The creation of ketones is a byproduct of this metabolic state. Ketones are a source of fuel, just as glucose is a source of fuel. Ketones tend to have some added benefits, though. What role does Ketosis play in human health? Ketosis allows our bodies to function in the absence of carbohydrates, both physically and mentally. Instead of burning carbohydrates, or converting protein to glucose, the body burns ketones. This is pretty much a survival mechanism. It allows your body to function in a state of caloric deprivation. This is why ketosis often gets bad press (as it’s linked to “starvation”). Being a survival mechanism doesn’t make it invalid as a strategy, though. There can still be potential benefits to be had. Let’s cover a few of them… Ketosis and Accelerated Fat Loss Being in ketosis Continue reading >>
