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 >>
10 Signs And Symptoms That You're In Ketosis
The ketogenic diet is a popular, effective way to lose weight and improve health. When followed correctly, this low-carb, high-fat diet will raise blood ketone levels. These provide a new fuel source for your cells, and cause most of the unique health benefits of this diet (1, 2, 3). On a ketogenic diet, your body undergoes many biological adaptions, including a reduction in insulin and increased fat breakdown. When this happens, your liver starts producing large amounts of ketones to supply energy for your brain. However, it can often be hard to know whether you're "in ketosis" or not. Here are 10 common signs and symptoms of ketosis, both positive and negative. People often report bad breath once they reach full ketosis. It's actually a common side effect. Many people on ketogenic diets and similar diets, such as the Atkins diet, report that their breath takes on a fruity smell. This is caused by elevated ketone levels. The specific culprit is acetone, a ketone that exits the body in your urine and breath (4). While this breath may be less than ideal for your social life, it can be a positive sign for your diet. Many ketogenic dieters brush their teeth several times per day, or use sugar-free gum to solve the issue. If you're using gum or other alternatives like sugar-free drinks, check the label for carbs. These may raise your blood sugar levels and reduce ketone levels. The bad breath usually goes away after some time on the diet. It is not a permanent thing. The ketone acetone is partly expelled via your breath, which can cause bad or fruity-smelling breath on a ketogenic diet. Ketogenic diets, along with normal low-carb diets, are highly effective for losing weight (5, 6). As dozens of weight loss studies have shown, you will likely experience both short- and long Continue reading >>
What Are The Dangers Of The Ketosis Diet?
In the late 1990s and early 2000s, when the "Atkins" and low carb dieting thing was just coming on in a big way, there was a terrific number of idiotic claims made about the dangers of it -- many of them confusing (as the questioner points out) diabetic ketoacidosis, a serious condition, with voluntary nutritional ketosis, even though there is no relation whatever. But, leaving all that aside, some caution is in order. The diet seems to stress the adrenals. This has been noted anecdotally by many people who've followed the diet. It was also noted by Dr Wolfgang Lutz, one of the early pioneers of the diet, who personally practiced the diet for 40-odd years, as well as advocated the diet to thousands of his patients. He noted in his book on the subject ("Life Without Bread" was the title, though it was published later I believe under a different title) that some patients would suffer mild autoimmune reactions that required small doses of corticosteroids to control. This sounds like what would happen if the adrenals are failing to produce a normal amount of steroids. You can find a lot more of a mostly-anecdotal nature by searching for "ketogenic jaminet". Paul Jaminet is a popular health blogger who has written about what he perceives to be problems with the ketogenic diet, including the possibility of deficiency of mucus and other key glycoproteins. He has some scientific backing for what he is saying, but it is far from air-tight. Read and judge for yourself. You can also learn a lot from the comments below his posts. Jaminet and others have also written about the risk of kidney stones on the ketogenic diet, and this is a serious concern, albeit a rare occurence. As far as the kidney stress goes: this would I believe be easy to avert simply by taking some alkali during Continue reading >>
Farming: Why Are Most Cows Fed Corn Instead Of Grass?
Most cows are not fed corn. As a matter of fact most cattle aren't even on a high-grain diet for most, if not all, of their lives. Most cattle are actually grass-fed. Just not grass-finished. There's around 89 million beef cattle in the US, 9.3 million dairy cattle and 12.1 million cattle currently in the feedlot being finished (that according to USDA statistics from July 1, 2015). The 89 million beef cattle are breeding cattle: Beef cows, replacement heifers, and bulls. The 9.3 million dairy cattle are primarily dairy cows used in milk production. And the 12.1 million cattle and calves in the feedlot are both beef and dairy of various ages. Now, look at the 89 million number again. That's 95% of the total cattle herd inventory of the United States (which is currently sitting at 93.4 million cattle). That equates to "most cows/cattle." And what most people don't know (nor have most acknowledged here, except for one) is that those 89 million cattle are grass or forage-fed. That means that those cattle are on pasture or range from spring until fall and fed hay in the winter. They are being fed and eating grass and forbs on either an extensive or intensive (all depending on grazing management, most operations choose an extensive to a happy medium between extensive and intensive) grazing system. Corn or other grains are optional, and only fed when and if the animals need it if feed supplies are low and straw is only to be fed (cattle can do quite well on straw if supplemented with grain for added carbohydrate and protein) but never as a main constituent of their diet. Certainly not like finisher or dairy cattle. The other interesting thing most people miss is that cattle in the feedlot have not been raised in the feedlot. Most cattle, which are largely beef with only maybe Continue reading >>

Best wishes, and to all the new people out there – good luck and happy dieting! Frequently Asked Questions Click any of the questions below and it will take you to the answer. How Long Does It Take To Get Into Ketosis? A ketogenic diet is not a diet that you can whimfully choose to go on and off of at any point. It takes time for your body to adjust and go into a state known as ketosis. This process? Anywhere from 2 – 7 days, depending on your body type, activity levels, and what you’re eating. The fastest way to get into ketosis is to exercise on an empty stomach, restrict your carbohydrate intake to 20g or less per day, and be vigilant with your water intake. To improve the rate at which you enter ketosis, there is a method called Fat Fasting. I’ve written an article on Fat Fasting on a Ketogenic Diet and everything involved with it. Make sure that if you use this method, it is only for a few days, otherwise it can bring harm to you. Where Can I Find Low Carb Recipes? Everywhere on the internet!

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 >>
Lose Weight By Achieving Optimal Ketosis
Do you want to lose weight? Here’s number 16 of my 18 best tips. All of the published tips can be found on the How to Lose Weight page. Before we get started, here’s a short recap of the tips so far: The first and most crucial piece of advice was to choose a low-carb diet. The next were eating when hungry, eating real food, eating only when hungry, measuring progress wisely, being persistent, avoiding fruit, beer and artificial sweeteners, review your medications, stressing less and sleeping more, eating less dairy and nut products, stocking up on vitamins and minerals, using intermittent fasting and finally, exercising smart. This is number sixteen: 16. Get into optimal ketosis Warning: Not recommended for type 1 diabetics, see below. We’ve now arrived at tip number 16. If you’re still having trouble losing weight, despite following the 15 pieces of advice listed above, it might be a good idea to bring out the heavy artillery: optimal ketosis. Many people stalling at weight plateaus while on a low carb diet have found optimal ketosis helpful. It’s what can melt the fat off once again. So how does this work? A quick run-through: The first tip was to eat low carb. This is because a low-carb diet lowers your levels of the fat-storing hormone insulin, allowing your fat deposits to shrink and release their stored energy. This tends to cause you to want to consume less calories than you expend – without hunger – and lose weight. Several of the tips mentioned above are about fine-tuning your diet to better this effect. Video course Do you know exactly how to eat a low-carb and high fat diet (LCHF)? This is required for ketosis. If not the easiest way is watching this high quality 11-minute video course on how to eat LCHF, and the most important things to think a Continue reading >>
What Is Ketosis, And How Long Does It Take To Get Into Ketosis?
Ketosis is a natural state of the body in which it is fueled almost solely by fat. This happens when a person fasts or adheres to a very low carbohydrate diet. The exciting thing about ketosis and ketogenic diets is that you can lose a lot of weight while eating a normal quantity of food. You don’t have to suffer through skimpy portions. There are other benefits of keeping a ketogenic diet as well. These will be explained in the following article. An Explanation of Ketosis The root “keto” in the word ketosis comes from the type of fuel that the body produces when blood sugar is in low supply. The small molecules that are used as fuel are called “ketones.” If you consume very few carbohydrates and only a moderate amount of protein, then the body begins to produce ketones. Ketones are made by the liver from fat. Both the body and the brain can use them as fuel. The brain cannot directly function from fat. It must convert the fat into ketones. Legionella Testing Lab - High Quality Lab Results CDC ELITE & NYSDOH ELAP Certified - Fast Results North America Lab Locations legionellatesting.com When you go on a ketogenic diet, your body almost solely runs on fat. Your insulin levels become rather low as well. Since you are burning so much fat, this is a great way to lose weight. Studies show that ketogenic diets result in greater weight loss. The fastest way to get into ketosis is by fasting. However, you cannot fast for very long, so you need to start a low carb diet. The Brain and Ketones Many people think that the brain needs carbohydrates to function. This is not really true. The brain can work well simply by burning ketones. The reality is that many people feel like they have even more energy and focus when they are fueled by ketones. Benefits of Ketosis There ar Continue reading >>
When Does Ketosis Occur?
Ketosis is marked by the presence of ketones in your blood. Ketones are produced as part of your body's natural metabolic processes, but high levels of ketones may be a sign of malnutrition or low insulin levels. On the other hand, some diets aim to cause ketosis to help with weight loss or to control epilepsy. Video of the Day Ketones are produced by your body when you break down fats to use as energy. Fats are typically your body's "backup" energy source, because carbohydrates can be burned for energy more quickly. However, when you do not have enough carbohydrates to supply all of your body's energy needs, your body will turn to other sources of energy, such as your fats. Your fats are broken down into ketones, which can then be used as a source of energy for your cells. One thing that can cause ketosis is diabetic ketoacidosis. Diabetic ketoacidosis occurs as a result of type I diabetes, which causes your pancreas to produce little or no insulin. Diabetic ketoacidosis is caused by extremely low insulin levels, which prevents your cells from effectively using the glucose in your blood. As a result, your cells will break down fats for energy, resulting in ketosis. Ketosis can also occur due to a diet that is very low in carbohydrates. Extreme carbohydrate reduction also forces the metabolism of fats for energy. This is the basis behind many of the "low-carb" diets such as the Atkins diet. A specialized diet that is designed to induce ketone production can also be used to treat some cases of epilepsy. One of the side effects of ketone production is acidosis. When ketones are produced, the body also produces extra levels of acidic substances. This can lower the pH of your blood, which is a measurement of the balance of acids and bases. The balance of acids and bases in Continue reading >>
Ketogenic Diet: Are There Any Foods Or Supplements I Can Eat To Speed Up Ketosis?
If you want to help yourself get into ketosis faster then using a high quality MCT (Medium Chain Triglyceride) Oil will speed this up. I think Dave Asprey makes the best oils. The next level down is the standard MCT Oil which has both C8 and C10 chains XCT Oil - 32 oz. By far my favorite way of getting into and staying in Ketosis (and this is coming from somebody who follows all the correct nutritional rules) is Exogenous Ketones. These put you into a state of Ketosis almost immediately (and that is reflected in the price range). Until now most of them were too unpalatable to bother with but there have been some fantastic innovations in the last year. I really like KetoSports KetoCaNa (10.75oz) The Original Exogenous Ketone Supplement - it has a very pleasant taste and does not have any sugar, unlike some of the other brands. Anyway, best of luck to you. And if you have any more questions pop them in the comments below. Disclosure: Some of the links above are affiliate links.

How Do We Follow Keto Diet Without Harming Our Body Where No Nutrition Deficit Happens?
So basically, ketosis occurs when there's no glycogen left in your body or there's no external supply/intake of glycogen/carbs in to the body. So every cell in your body starts to turn into fat burning mode. So basically on ketosis your body needs 75% fats, 20% proteins, 5% carbs. For a person on a 3000 calorie diet that equals to 250 grams of fat, 155 protein, 38 carbs. So basically your fats should be 80% from clean sources. Coconut oils, olive oil, MCT's. This is a very key step. Second important thing being since you cut carbs, your body won't hold water and you'll get dehydrated so it's important for you to up your sodium intake by adding more salt to food and also drink more water. Third thing being there are three 3 minerals which are important being magnesium, potassium, calcium. You can supplement calcium to your body. But it's very important that you get magnesium and potassium from natural sources such as vegetables, so for the above diet you have 38 grams of carbs, so make sure all those 38 grams of carbs comes from vegetables. This will help you prevent a fatty liver but will make sure you aren't nutrient deficient. Also add a good multivitamin, fish oil, B12 vitamin, iron tablet. This will make sure you're all good and healthy. Also doing all this can help you avoid keto-flu. Avoid beets, carrots. Have lots of green leafy veggies, cabbage, beans, peppers etc. Continue reading >>
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 >>
Is Doing Hitt A Good Way To Go Into Ketosis Fast?
You asked, Is doing HITT a good way to go into ketosis fast? Ketosis occurs at the point in time when the body exhausts sufficient blood glucose to sustain metabolic energy and biosynthesis needs. Gluconeogenesis is the short-term energy bridge when episodic metabolic needs arise (whereby the liver transforms bodily proteins into glucose); however: It takes the average male 72 hours to engage ketosis and average female 48 hours. It is less the excessive immediate energy demands that speed ketogenesis than the constant demand for energy above current blood glucose supply. As such, intense short-term demands are inconsequential to the speed of ketogenesis–it’s the duration of those demands that matter. The most correlative factor regarding increasing the speed of ketosis is developing underlying ketoadapted fitness in the individual. Much of ketoadapted fitness is easily cultivated through diet (i.e. ketogenic) and short-term water fasting (i.e. more than three and up to 40 days*). So judging HIIT as either a good or bad way to engage ketosis really depends upon the underlying ketoadapted fitness of the individual (or lack thereof) and whether or not you want to accomplish additional outcomes by invoking that practice. *Long-term fasting (on water alone) has been repeatedly defined as fasts exceeding 40 days, in both extant literature and clinical records of fasting as a therapeutic protocol. Unfortunately the wisdom and execution of such practices are virtually extinct in modern allopathic practice, for a variety of reasons. As such it is rarely recommended to fast for more than 10 days without a fasting expert with direct experience, as conventional medical doctors simply have no clue. And keto-adapted fitness can be easily cultivated within short-term fasting proto Continue reading >>
Ketosis, Ketones, And How It All Works
Ketosis is a process that the body does on an everyday basis, regardless of the number of carbs you eat. Your body adapts to what is put in it, processing different types of nutrients into the fuels that it needs. Proteins, fats, and carbs can all be processed for use. Eating a low carb, high fat diet just ramps up this process, which is a normal and safe chemical reaction. When you eat carbohydrate based foods or excess amounts of protein, your body will break this down into sugar – known as glucose. Why? Glucose is needed in the creation of ATP (an energy molecule), which is a fuel that is needed for the daily activities and maintenance inside our bodies. If you’ve ever used our keto calculator to determine your caloric needs, you will see that your body uses up quite a lot of calories. It’s true, our bodies use up much of the nutrients we intake just to maintain itself on a daily basis. If you eat enough food, there will likely be an excess of glucose that your body doesn’t need. There are two main things that happen to excess glucose if your body doesn’t need it: Glycogenesis. Excess glucose will be converted to glycogen and stored in your liver and muscles. Estimates show that only about half of your daily energy can be stored as glycogen. Lipogenesis. If there’s already enough glycogen in your muscles and liver, any extra glucose will be converted into fats and stored. So, what happens to you once your body has no more glucose or glycogen? Ketosis happens. When your body has no access to food, like when you are sleeping or when you are on a ketogenic diet, the body will burn fat and create molecules called ketones. We can thank our body’s ability to switch metabolic pathways for that. These ketones are created when the body breaks down fats, creating Continue reading >>
Do You Have Special Methods Of Lose Fat Except Do Exercise?
Water Fast Water fasting offers the quickest detox and weight loss. It is advisable to take help from a doctor before undertaking long fasts. If done with care, a one week fast can give immense physical and mental strength. It is also the most challenging fast to perform in the first few days. Basics of Water Fasting The rules of water fasting are simple: You eat and drink nothing but water for the duration of the fast, which may last for several days. People who can’t safely stop taking a prescription medication should not embark on a water fast. The first few days of a fast are the most difficult. Besides the emotional challenge of going without food, these first days may have the most intense and uncomfortable symptoms of detoxification. After that, the body adjusts to the new fasting state, and most individuals feel little further discomfort, even hunger disappears. After 2-3 days, the body goes into a state called ketosis, where it begins to fuel itself internally by burning fat cells. Ketosis occurs around 48 hours for women and 72 hours for men according. The length of time one can safely operate in ketosis varies from person to person. Rest - It is important to allow plenty of opportunity for rest, both physical and emotional. Give yourself permission to nap if ever you feel the need. Breaking the fast - When breaking a fast, begin with frequent small meals, every 2 hours or so, progressing gradually toward larger meals with more time in between them until you reach a "normal" eating routine, such as 3 meals and 2 snacks in a day's time. Hope it help. Continue reading >>
