What Is It Like To Experience Ketosis?
Ketosis is great, it's the transition that stinks. Being in ketosis means that your body is receiving its primary energy from ketones, which come from fat. The standard American diet is pretty high in carbohydrates, which convert to glucose in the blood. As long as your body has glucose around, it will always pick that over ketones. The transition from processing glucose to processing ketones invariably creates a gap in energy delivery to the brain (and other parts of the body), which will NOT kill you but which WILL trigger a stress response in the form of aches, headaches, fatigue, fogginess, etc. Really, it will vary by person. YMMV. If you fast (don't eat anything), you could be in ketosis in 24-48 hours (apparently, I've never tried it). If you carb-restrict your diet to less than 20-40g carbohydrates per day, you could be in ketosis within 3-5 days. It depends on a few factors, but mostly how much glycogen you have stored in your liver (glycogen converts to glucose). I was listening to a Tim Ferris podcast with Dom D'Agostino (Dom D’Agostino on Fasting, Ketosis, and the End of Cancer) where they talk about exogenous ketones among other things. Exogenous ketones are apparently available in several forms (BHB monoester, AcAc di-ester, BHB mineral salt) and if taken during the transition period will eradicate any negative side effects. I haven't tried them for myself (Peter Attia has! but it's intriguing to think that the one thing that prevents most people from enjoying ketosis (the crappy transition) could be optional. While in ketosis, I experience a little bit higher than normal energy level and fewer food cravings. I can think more clearly. I get hungry less often. I am frequently thirsty (this is normal side effect, and if you are in ketosis you should be dri Continue reading >>
Ketosis And Fatty Liver
Fatty liver is usually associated with alcohol abuse, but even people who don't drink can develop nonalcoholic fatty liver disease, or NAFLD. NAFLD includes asymptomatic steatosis, meaning simple fatty liver, which can progress to steatohepatitis, meaning inflamed fatty liver. Later, the disease can cause fibrosis, or scarring, and ultimately cirrhosis, which is permanent. Alcoholic fatty liver can only be treated by abstaining from alcohol in the early stages of the disease. But, because NAFLD is likely diet-related, it might be reversible by substantially reducing carbohydrate intake by means of a ketogenic diet. Video of the Day NAFLD is associated with obesity -- especially abdominal, insulin resistance, elevated blood sugar, inflammation and high serum triglycerides. These are all signs of metabolic syndrome, considered the precurser to Type 2 diabetes. When the body cannot use sugar properly, some of it is converted to fat -- triglycerides -- by the liver, where it can accumulate. A 2009 study conducted at the Center for Human Nutrition and Atkins Center of Excellence in Obesity Medicine found that excess liver fat is probably the major culprit behind the health issues often associated with obesity. The Ketogenic Diet The ketogenic diet is a high-protein, high-fat, carbohydrate-restricted diet usually used for weight loss. Reducing or eliminating dietary carbohydrate forces the body to rely on stored fat for energy. However, the body metabolizes fat differently in the absence of carbohydrates, resulting in a condition called ketosis. Incompletely metabolized fat forms molecules called ketones, which accumulate in the blood and urine. Ketones have limited value as an energy source in the absence of carbohydrate, mainly for the brain, but most are excreted in the ur Continue reading >>
How Can I Get Back Into Ketosis?
What is the fastest way to get into ketosis? It’s FASTING. When liver glycogen gets depleted, the liver will then start producing ketones that begin to provide energy to the body. You can get into ketosis and stay there if you were to fast and not eat any calories for 3+ days. However, this may not happen even if you try very hard. What stops you from getting into ketosis are elevated blood sugar levels caused by too much cortisol and stress. I’m about to share with you some pointers. Drink salted water during your fast. To control cortisol and balance those electrolytes. Working out may seem reasonable but it can be counterproductive. You don’t need to exercise hard to empty your liver glycogen because they will be depleted within the first day already. This is the fastest way to get into ketosis and start a ketogenic diet as a long term thing. You’ll start reaping the actual benefits only after 3-4 weeks. Check out my video: Continue reading >>
How Does The Ketogenic Diet Work?
The Keto diet is not really a diet, but rather a lifestyle change. A Ketogenic diet is best described as a low carb, moderate protein, and high fat diet. This combination changes the way energy is used in the body. Fat is converted in the liver into fatty acids and ketone bodies. Another effect of the diet is that it lowers glucose levels and improves insulin resistance. An elevated level of ketone bodies in the blood, a state known as ketosis, leads to a reduction in the occurrence of epileptic seizures. Ketogenic Diet Macros Typically, the ketogenic diet consists of only 30-50 grams of carbohydrates a day. High in fat Moderate Protein The beginning of a ketogenic diet can be challenging for some who are not used to eating a very low carbohydrate diet. You’ll probably experience a lack of energy and brain fog as your body is in the beginning stages of making a metabolic shift. This shift is simply your body beginning to use fat for fuel rather than glucose. Your brain and body actually prefers to run on keytones rather than glucose for energy. The goal here is to use the fat on your body as fuel rather than glucose (from sugar or carbs) to burn fat and for overall daily energy requirements.

Keto: The Best Fatty Liver Diet
Fatty liver disease is exactly what the name suggests – a disease characterized by the build up of fat in the liver. There are two main types of fatty liver disease: Nonalcoholic fatty liver disease Alcoholic fatty liver disease (also called alcoholic steatohepatitis) Both types of fatty liver disease are diagnosed when fat makes up at least 10% of the liver, but the cause of the fat build up is different for each type. The cause of alcoholic fatty liver disease is obvious. The amount of alcohol it takes to cause fatty build up in the liver, however, is not so obvious. The Liver Foundation suggests consuming no more than 14 drinks a week for men and 7 drinks a week for women. Anything more than may cause fat to build up in the liver. The treatment for alcoholic fatty liver disease is simple enough — stop drinking alcohol. Studies confirm that cessation of alcohol consumption can reverse alcoholic fatty liver disease. However, the cause and treatment of nonalcoholic fatty liver disease are not as obvious. This is because many different factors (other than alcohol) can cause fat to build up in the liver. The Truth About Nonalcoholic Fatty Liver Disease Nonalcoholic fatty liver disease affects 20-30% of adult populations in developed countries, but the mechanisms underlying its cause are incompletely understood. We can, however, take some clues from other common diseases to figure out why this happens. In epidemiological studies including people with type 2 diabetes, 62 to 69% of them also had nonalcoholic fatty liver disease. Another study found that 50% of patients with dyslipidemia (abnormally elevated cholesterol levels) had nonalcoholic fatty liver disease. Obesity, metabolic syndrome, and heart disease are also closely linked with nonalcoholic fatty liver disease Continue reading >>
What Is It Like To Go On A Ketogenic Diet?
It's do-able. Some people love it and some people hate it. Personally, I find that nutritional ketosis is almost ideal for me, whereas "normal" eating with lots of carbs in my diet leads to feelings of non-satiety, drowsiness, mood swings, insulin spikes, bloating, and sometimes nausea. A ketogenic diet consists of 70-80% calories from fat, 15-25% calories from protein, and 0-5% calories from net carbohydrates (carbs). You must restrict your daily net carbs to 20-40g daily. (total grams carbs) - (grams fiber) = (net grams carbs) Your transition period depends on a few factors: how strictly you limit your carbohydrate intake, how much energy you expend day-to-day, and how much energy in the form of glucose and glycogen you have stored in your body currently. My transition period takes 3 days. Day 1: This is an easy day. Your blood is still filled with circulating glucose, and any deficit will be taken from the glycogen in your liver to be converted to glucose. You may feel hunger pangs by the afternoon, and a small dip in insulin, which will feel normal to you because this is what happens every day on a normal diet and you are used to it. Day 2: This is an easy day, too. Your body is happily pulling glycogen from your liver, converting it to glucose, and all is well. Any small amount of carbs that you consume are burned away, nothing is being stored. You may feel the typical afternoon slowdown and hunger, as on day 1. Day 3: Hard day. Your body has been (or is nearly) depleted of glucose and glycogen. The small amount of carbs that you consume are not enough to fuel your brain. You have a feeling of satiety from all the fat you are consuming, but you may feel achy, have headaches, and feel sluggish. Your body is alerting you to the lack of glucose and glycogen. It will t Continue reading >>
Is A Ketogenic Diet Hard On The Liver?
Ketogenesis exists to some extent between meals. Evidence would have been observed if it were acutely harmful. It is natural for omnivorous mammals including primates to gain fat from the seasonal availability of fruit and burn it during other seasons. Liver stress does exist. My family has seen it in necropsy of both a burro and a cat. In both cases, excess intake of starch resulted in accumulation of body fat. In response to digestive discomfort, neither animal appeared to be losing weight because both started out fat. Unlike humans, neither had evolved to live off of body fat. In humans, hepatic lipidosis most commonly results from insulin resistance and metabolic syndrome, exactly the opposite of ketogenesis. Before effective drugs, epileptics were shown to respond to ketogenic diets with almost all of daily calories coming from fat. They died from causes other than liver failure. This claim has been repeated in the past by vegetarians who have no problem with the liver having to store, not just process, as much as a pound of glucose per day. Continue reading >>
Is Dietary Ketosis Harmful To The Liver?
The mild dietary ketosis, such as that which is experienced during the Weight Loss phase of the Lean for Life program, is not harmful to individuals with a normal, healthy, functioning liver. Here is some information about ketosis that may help you to understand its role in weight loss: The carbohydrates you eat are converted to glucose, which is the body’s primary source of energy. Whenever your intake of carbohydrates is limited to a certain range, for a long enough period of time, you’ll reach a point where your body draws on its alternate energy system, fat stores, for fuel. This means your body burns fat and turns it into a source of fuel called ketones. (Ketones are produced whenever body fat is burned.) When you burn a larger amount of fat than is immediately needed for energy, the excess ketones are discarded in the urine. Being in ketosis means your body has burned a large amount of fat in response to the fact that it didn’t have sufficient glucose available for energy needs. Dietary ketosis is among the most misunderstood concepts in nutrition because it is often confused with ketoacidosis, which is a life-threatening condition most often associated with uncontrolled insulin-deficient Type 1 diabetes. In the Type 1 diabetic, the absence of insulin leads to a toxic build-up of blood glucose and an extreme break-down of fat and muscle tissue. This condition doesn’t occur in individuals who have even a small amount of insulin, whether from natural production or artificially administered. Dietary ketosis, however, is a natural adjustment to the body’s reduced intake of carbohydrates as the body shifts its primary source of energy from carbohydrates to stored fat. The presence of insulin keeps ketone production in check so that a mild, beneficial ketosis Continue reading >>
