Is There A Time Limit For Ketosis?
There are some examples of humans being in ketosis for extended periods without ill effects. As Rose mentioned, the Inuit probably lived more or less their whole lives in ketosis, or at least most of them were in ketosis most of the time. They weren't the only such culture, either???maybe the Masai and maybe the Bison people of the American Great Plains did likewise, at least sometimes. There there was the one-year-long experiment in which Vilhjalmur Stefannson and another subject ate nothing but meat while under medical observation. Then there are the thousands of children who have gone on a ketogenic diet to treat their epilepsy. Many of them stayed on the diet continuously for years. In Caraballo 2011 they reported on more than 200 patients who had been on the diet for between 1 and 12 years, with a mean of 3.5 years. In that and in other studies, it seems like there weren't any common, bad side-effects. (There were some side-effects, but they weren't too bad or too common. The worst was stunted growth, but I think that was not due to ketosis but due to the fact that those diets were usually calorie-restricted and water-restricted, and children need calories and water to grow!) Also, you have been in ketosis for a year or two straight. Before you started eating solid food. Also there are the modern group of zero-carb eaters, of which apparently Rose and my wife Ambimorph are the representatives on Paleohacks. They hang out on a forum named "Dirty Carnivore" and some of them (used to?) hang out on a forum called "Zeroing In On Health". There are apparently dozens of them, at least, who've stayed continuously in ketosis for at least a year. In short, I've looked for evidence that being in prolonged, continuous ketosis is harmful and I haven't found any. I don't see any Continue reading >>
Is The Keto Diet Safe? 10 Myth-busting Arguments For The Safety Of Ketosis
Is ketosis safe? The truth is that we can’t say for certain that it is 100% safe. Humans don’t understand everything under the branch of nutritional science and probably won’t for a very long time. As an individual, the only thing you can do is take a look at the research yourself and form your own conclusion. Personally, through the reading I’ve done and the experience I’ve had with the Keto diet, I’ve formed my own conclusion that ketosis is safe. Could I be wrong? Absolutely. But I could also be right. I’m willing to take that risk in order to follow a diet which could maximize longevity, well being and function. My personal conclusion shouldn’t matter to you though. You need to do your own research and come to your own conclusion. I’ve put together this post to organize all of the issues surrounding the safety of ketosis so that you can make your own decision. In trying to prove something to be safe there are two ways to go about it. Disprove the claims of danger Show evidence which may be correlated with safety This article will dispel the top 10 claims people make in an argument to label ketosis as dangerous. Like I said, the science on ketosis is still quite immature. The following data is not meant to 100% prove or disprove the safety of ketosis. It’s merely the information we have available today which can help us form a nutritional strategy we feel is best for ourselves. I’m not a doctor or a researcher. The following information is material I’ve collected in my attempt to feel confident following a Keto diet indefinitely. Most of it is sourced from doctors or authors although I have also included anecdotal accounts from experiences posted on message boards and Reddit. I know, much of the information here isn’t sourced directly from s Continue reading >>
How Long Can You Stay In Ketosis Safely?
Are you looking for a diet for weight-loss or fat-loss? If so then you might be interested in ketosis. The question is whether you can stay on it permanently. That’s because it’s critical for any ‘diet” to become part of your everyday life and eating habits. It’s important to first understand what it is all about. It’s a natural state of the human body when it’s fueled almost 100% by body fat. This state takes place during a low-carb or “keto” diet as well as during fasting. It’s important to understand how this process is related to fat loss. The term originates from the fact that the human produce produces tin fuel molecules known as “ketones.” When the body doesn’t have enough blood sugar/glucose it gets energy from this source. The body produces chemicals when it gets a very low supply of carbs and a moderate amount of protein. The liver’s fat produces ketones then the body and brain use it for fuel. The process is especially important for the brain since the organ can only run from glucose/ketones. Medical research shows that early humans probably experienced the state very often. The reason is that hunter-gatherer societies ate a high-meat diet and had less access to carbohydrates than modern humans. As a result human bodies evolved so they could get energy from fat even though it mimicked starvation mode. Today there are various reasons why people use the ketogenic meal plan. Some of the most common ones are to lose weight or control epilepsy. The firm supporters point out the health benefits of the diet but others note that it’s a dangerous “hack” of the body’s regular metabolic system. These are the benefits to this process: Less eating due to no appetite More fat loss from abdominal cavity Lower blood sugar/insulin levels Lo Continue reading >>
Keep Yourself In Ketosis
When talking about a Grain Brain lifestyle, and the very similar ketogenic diet, it’s frequently mentioned that we are aiming to keep our bodies in ketosis. However, if you’re new to my work, it may be that you’re not exactly sure what ketosis is, or why we should be worrying about getting our body into this state. Allow me to explain. Ketones are a special type of fat that can stimulate the pathways that enhance the growth of new neural networks in the brain. A ketogenic diet is one that is high in fats, and this diet has been a tool of researchers for years, used notably in a 2005 study on Parkinson’s patients finding an improvement in symptoms after just 28 days. The improvements were on par with those made possible via medication and brain surgery. Other research has shown the ketogenic diet to be remarkably effective in treating some forms of epilepsy, and even brain tumors. Ketones do more than just that though. They increase glutathione, a powerful, brain-protective antioxidant. Ketones facilitate the production of mitochondria, one of the most important actors in the coordinated production that is the human body. And that’s just the tip of the iceberg. Our bodies are said to enter ketosis at the point when blood sugar levels are low and liver glycogen are no longer available to produce glucose as a fuel for cellular energy production. At this point, not only is the body doing the natural thing, and burning off fat, it’s also powering up the brain with a super efficient fuel. We can jump start ourselves into ketosis with a brief fast, allowing our body to quickly burn through the carbs that are in our system, and turn to fat for fuel. A ketogenic diet is one that derives around 80% or more of of its calories from fat, and the rest from carbs and prote Continue reading >>
What Is Ketosis?
"Ketosis" is a word you'll probably see when you're looking for information on diabetes or weight loss. Is it a good thing or a bad thing? That depends. Ketosis is a normal metabolic process, something your body does to keep working. When it doesn't have enough carbohydrates from food for your cells to burn for energy, it burns fat instead. As part of this process, it makes ketones. If you're healthy and eating a balanced diet, your body controls how much fat it burns, and you don't normally make or use ketones. But when you cut way back on your calories or carbs, your body will switch to ketosis for energy. It can also happen after exercising for a long time and during pregnancy. For people with uncontrolled diabetes, ketosis is a sign of not using enough insulin. Ketosis can become dangerous when ketones build up. High levels lead to dehydration and change the chemical balance of your blood. Ketosis is a popular weight loss strategy. Low-carb eating plans include the first part of the Atkins diet and the Paleo diet, which stress proteins for fueling your body. In addition to helping you burn fat, ketosis can make you feel less hungry. It also helps you maintain muscle. For healthy people who don't have diabetes and aren't pregnant, ketosis usually kicks in after 3 or 4 days of eating less than 50 grams of carbohydrates per day. That's about 3 slices of bread, a cup of low-fat fruit yogurt, or two small bananas. You can start ketosis by fasting, too. Doctors may put children who have epilepsy on a ketogenic diet, a special high-fat, very low-carb and protein plan, because it might help prevent seizures. Adults with epilepsy sometimes eat modified Atkins diets. Some research suggests that ketogenic diets might help lower your risk of heart disease. Other studies show sp Continue reading >>
Long-term Effects Of A Ketogenic Diet In Obese Patients
Go to: Abstract Although various studies have examined the short-term effects of a ketogenic diet in reducing weight in obese patients, its long-term effects on various physical and biochemical parameters are not known. To determine the effects of a 24-week ketogenic diet (consisting of 30 g carbohydrate, 1 g/kg body weight protein, 20% saturated fat, and 80% polyunsaturated and monounsaturated fat) in obese patients. In the present study, 83 obese patients (39 men and 44 women) with a body mass index greater than 35 kg/m2, and high glucose and cholesterol levels were selected. The body weight, body mass index, total cholesterol, low density lipoprotein (LDL) cholesterol, high density lipoprotein (HDL) cholesterol, triglycerides, fasting blood sugar, urea and creatinine levels were determined before and after the administration of the ketogenic diet. Changes in these parameters were monitored after eight, 16 and 24 weeks of treatment. The weight and body mass index of the patients decreased significantly (P<0.0001). The level of total cholesterol decreased from week 1 to week 24. HDL cholesterol levels significantly increased, whereas LDL cholesterol levels significantly decreased after treatment. The level of triglycerides decreased significantly following 24 weeks of treatment. The level of blood glucose significantly decreased. The changes in the level of urea and creatinine were not statistically significant. The present study shows the beneficial effects of a long-term ketogenic diet. It significantly reduced the body weight and body mass index of the patients. Furthermore, it decreased the level of triglycerides, LDL cholesterol and blood glucose, and increased the level of HDL cholesterol. Administering a ketogenic diet for a relatively longer period of time did Continue reading >>

How To Maintain Ketosis
The ketogenic diet is all the rage right now, and more people are learning about the benefits of ketosis on their health and weight loss goals. However, there’s still some confusion around the process itself and the correct ways to maintain ketosis. This information will help you maintain a steady state of ketosis safely and efficiently, no matter your needs. Getting into Ketosis First things first. Before we can maintain ketosis we have to get understand what is ketosis and get into this primal metabolic state. Ketosis occurs when the body has little to no access to carbohydrates, its normal source of fuel, and begins breaking down and burning fat for energy instead. The ketosis process can have many benefits including: Curbed hunger and faster weight loss Improved blood sugar regulation Enhanced cognitive performance Better mental focus Less chance of inflammation Reducing risk for conditions like type II diabetes When the body’s in ketosis, fats are broken down and ketone bodies, or “ketones,” are created for the body to use for energy. Three Main Ways of Maintaining Ketosis Long-term Short-term Cyclical The way you use the ketogenic diet depends on your specific needs, but what’s important is making sure you maintain a state of ketosis during the full time you’re on keto. This is not the same as simple going low-carb, and it requires some extra effort and tracking. However, the results are worth the extra work! Short-Term vs Long-Term Ketosis Just as it sounds, the only difference between short- and long-term ketosis is the amount of time you properly follow the ketogenic diet. The standard version of the ketogenic diet involves eating around 20-50 grams of net carbs per day to keep the body in ketosis, although the exact amount depends on each person. C Continue reading >>
Is Ketosis Safe And Does It Have Side Effects?
Some people think that ketosis is extremely dangerous. However, they might be confusing ketosis with ketoacidosis, which is completely different. While ketoacidosis is a serious condition caused by uncontrolled diabetes, ketosis is a natural metabolic state. In fact, ketosis and ketogenic diets have been studied extensively and shown to have major benefits for weight loss (1, 2). Ketogenic diets have also been shown to have therapeutic effects in epilepsy, type 2 diabetes and several other chronic conditions (3, 4, 5, 6). Ketosis is generally considered to be safe for most people. However, it may lead to a few side effects, especially in the beginning. First, it's necessary to understand what ketosis is. Ketosis is a natural part of metabolism. It happens either when carbohydrate intake is very low (such as on a ketogenic diet), or when you haven't eaten for a long time. Both of these lead to reduced insulin levels, which causes a lot of fat to be released from your fat cells. When this happens, the liver gets flooded with fat, which turns a large part of it into ketones. During ketosis, many parts of your body are burning ketones for energy instead of carbs. This includes a large part of the brain. However, this doesn't happen instantly. It takes your body and brain some time to "adapt" to burning fat and ketones instead of carbs. During this adaptation phase, you may experience some temporary side effects. These are generally referred to as the "low-carb flu" or "keto flu." In ketosis, parts of the body and brain use ketones for fuel instead of carbs. It can take some time for your body to adapt to this. In the beginning of ketosis, you may experience a range of negative symptoms. They are often referred to as "low-carb flu" or "keto flu" because they resemble symptom 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!
