Is The Ketogenic Diet Safe For Weight Loss?
Share it: If you’ve been contemplating various weight-loss strategies, you may have run across the ketogenic diet. This dietary strategy, which is often used in a clinical setting to help improve seizure control in children with epilepsy, is picking up steam as an effective treatment for weight loss. But is it right for you? We turned to the experts to find out more. WHAT IS IT? The ketogenic diet is a high-fat, moderate-protein, low-carbohydrate diet that forces the body into a state of ketosis, where fat is burned for fuel instead of carbohydrate. (This isn’t to be confused with ketoacidosis, a dangerous condition typically caused by a lack of insulin in the body.) According to Dominic D’Agostino, a researcher at the University of South Florida who specializes in ketogenic diets, “The ‘classic ketogenic diet’ used originally for the management of drug-resistance seizures is a 4:1 ratio of fats to protein and carbohydrates.” That equates to about 80–90% fat, 5–15% protein and 5–10% carbohydrates. For weight loss, he says, this diet is typically modified “to allow a more liberal consumption of protein” (20–30%) with the same carbohydrate restriction. IS IT FOR YOU? Advocates of the ketogenic diet are quick to point out many of the benefits this diet can have for those looking to lose weight. “Rapid weight loss and a decrease in hunger are the most common and evident benefits,” says Kristen Mancinelli, MS, RD, author of “The Ketogenic Diet: A Scientifically Proven Approach to Fast, Healthy Weight Loss.” D’Agostino references promising studies that have been shown to “lower blood glucose levels, increase sensitivity to insulin, decrease inflammation and reduce triglyceride levels while raising HDL cholesterol.” READ MORE > 21 DIETIT Continue reading >>
The Keto Diet Is Gaining Popularity, But Is It Safe?
A new twist on extreme weight loss is catching on in some parts of the United States. It’s called the "keto diet." People promoting the diet say it uses the body’s own fat burning system to help people lose significant weight in as little as 10 days. It has also been known to help moderate the symptoms of children with epilepsy, although experts are not quite sure why it works. Proponents say the diet can produce quick weight loss and provide a person with more energy. However, critics say the diet is an unhealthy way to lose weight and in some instances it can be downright dangerous. Read More: What is the “Caveman Diet?” » What Is Ketosis? The “keto” diet is any extremely low- or no-carbohydrate diet that forces the body into a state of ketosis. Ketosis occurs when people eat a low- or no-carb diet and molecules called ketones build up in their bloodstream. Low carbohydrate levels cause blood sugar levels to drop and the body begins breaking down fat to use as energy. Ketosis is actually a mild form of ketoacidosis. Ketoacidosis mostly affects people with type 1 diabetes. In fact, it is the leading cause of death of people with diabetes who are under 24 years of age. However, many experts say ketosis itself is not necessarily harmful. Some studies, in fact, suggest that a ketogenic diet is safe for significantly overweight or obese people. However, other clinical reviews point out that patients on low-carbohydrate diets regain some of their lost weight within a year. Where It’s Helpful The keto diet was created by Dr. Gianfranco Cappello, an associate professor of surgery at the Sapienza University in Rome, Italy. He claims great success among thousands of users. In his study, more than 19,000 dieters experienced significant, rapid weight loss, few side Continue reading >>
A Rat Study Was Done That Concluded That Methyl Ethyl Ketone (mek) Helped With Epileptic Rats. Is It Safe For Humans To Ingest Mek Sold In A Hardware Store As An Exogenous Ketone To Maintain Ketosis?
I assume you’re talking about this paper? It was the closest one to your premise. I direct you to the first sentence of the abstract, which is repeated in the conclusion. “A ketogenic diet has been used successfully to treat patients with intractable epilepsy, although the mechanism is unknown.” (Emphasis is mine) It looks like they injected rats with various ketones, and found some anti-epileptic effects, but they still don’t know the mechanism, and the best hypothesis is that the protective effect comes from metabolic changes in the brain when it has to derive its energy from ketones rather than glucose. If you just inject ketones into yourself, you’re subjecting yourself to a lot of toxic crap, and not getting rid of any of the glucose. If there’s glucose present, body cells will preferentially use glucose as an energy source, not ketones. If you want these benefits, you’ll have to starve yourself of everything that contains glucose or can break down into glucose, and screw yourself over into a ketogenic state. I say ‘screw yourself over’ because this is a profoundly unhealthy state to find one’s metabolism in, and this is a treatment that only has relevance when all the safer alternatives have failed or are unavailable. I would also criticise this paper for one major flaw: they kept the rats on scopalomine (stated to be given specifically to limit the seizure activity) and diazepam (stated to be to increase survivability). That means that the rats were given two different well known and powerful anticonvulsants in addition to the MEK, with every dose. The only seizure activity seen was that on the EEG: none of the rats had externally observable seizures, the protective effects were inferred from EEG results. That in my opinion really dilutes any Continue reading >>
Is It Safe To Lift Weights In Ketosis?
Yes, it is. I do that all the time. Ketosis can be of different degrees - from mild to deep, depending on the concentration of ketone bodies in your blood. Lifting weights in ketosis does nothing harmful to your body - in fact it accelerates fat loss, so yes - it is safe. A different question is how effective it is. Some research shows that the process of generating maximal muscle effort is almost always glycolytic (i.e. - it depends on glucose). From that perspective it may seem that to be able to hit Personal Records and work with maximal weights, you pretty much need carbs. But here is my take on this: First, with any sensible training protocol, you don’t always hit PRs on each training day. In fact, constantly working out with maximal weights is as counterproductive as constantly working with low weights. If your training schedule is properly designed, your intensity would fluctuate and you would only need to hit PRs once every couple of months or so (if you are already moving massive weights - that frequency is going to be even lower). During the times of “normal” sub-maximal workouts you should be OK in any case. Second, you never really run out of glycogen, even when in deep ketosis (as your liver always synthesizes some through gluconeogenesis using glycerol as substrate and storing whatever low amounts of carbs you ingest). So, even if your muscle glycogen reserves may be lower than when you carb-load (at least in theory) - there should be enough to support that one maximal effort. Third, you may not even be after muscle mass gain - perhaps your primary goal is strength gain. If that’s the case, studies show that strength gains are unaffected under ketosis. And - although perhaps not documented in any formal “studies”, I either personally know or ha 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 >>
Is Keto And Ketosis Safe?
The ketogenic diet and ketosis are safe. Not only are they safe, but they are useful in helping people with many different conditions. The ketogenic diet has helped cancer patients, people with diabetes (type 1 and type 2), women with polycystic ovary syndrome, people with heart disease, and many others. So, where does the rumor that the ketogenic diet and ketosis may not be safe come from? Well, it starts with ketones. Rumors Spread Like Ketones in an Insulin Deficient Body One of the primary goals of the ketogenic diet is to enter ketosis (a normal metabolic process when ketones are produced for fuel). Ketosis is primarily regulated by the liver, which helps produce enough ketones to meet the body’s needs. However, ketone production can get out of hand when insulin is deficient, leading to ketoacidosis. This may be where the rumor that keto and ketosis are not safe came from. Ketoacidosis — A Serious Condition That Is Not Caused By The Ketogenic Diet Ketoacidosis is a serious condition caused by uncontrolled diabetes. It is brought on by being born without the ability to produce enough insulin (type 1 diabetes) or living a lifestyle that promotes insulin resistance (type 2 diabetes). In both cases, there isn’t enough insulin to tell that cells that energy is available (insulin deficiency). The lack of insulin signaling causes the fat cells and liver cells to go into starvation mode, even after a calorically dense meal. The fat cells begin to dump triglycerides into the blood to provide the other cells with energy because the cells are perceiving that there is no fuel available. Meanwhile, the liver starts mobilizing stored glycogen and using gluconeogenesis and ketogenesis to provide the body with sugar and ketones that it doesn’t need. All of this causes bloo 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 >>
Hormone Issues From Ketosis I'm Afraid Of Thyronamines Causing Insulin Resistance, What Are My Options? Is It Safe To Carb Up From 20 To 100 Or 200?
If anything on a ketogenic diet you will be insulin sensitive, which means that basically any carb you eat will effect you, so eat them strategically. Each gram of carbs that you put in your body can hold up to 3 grams of water. As for your thyronomaines causing insulting resistance, DO YOU HAVE DATA? Also what hormone issues are you referring to? Have you had bloods run? It’s hard to know what you are talking about. As for carving up from 20 to 100 to 200, you are perfectly fine, but what are your goals? I would like to answer this question in depth, but it needs some more development. Here is a video I did on the ketogenic diet: Please don’t forget to subscribe. 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 >>
Ketogenic Diet: Is The Ultimate Low-carb Diet Good For You?
Recently, many of my patients have been asking about a ketogenic diet. Is it safe? Would you recommend it? Despite the recent hype, a ketogenic diet is not something new. In medicine, we have been using it for almost 100 years to treat drug-resistant epilepsy, especially in children. In the 1970s, Dr. Atkins popularized his very-low-carbohydrate diet for weight loss that began with a very strict two-week ketogenic phase. Over the years, other fad diets incorporated a similar approach for weight loss. What is a ketogenic diet? In essence, it is a diet that causes the body to release ketones into the bloodstream. Most cells prefer to use blood sugar, which comes from carbohydrates, as the body’s main source of energy. In the absence of circulating blood sugar from food, we start breaking down stored fat into molecules called ketone bodies (the process is called ketosis). Once you reach ketosis, most cells will use ketone bodies to generate energy until we start eating carbohydrates again. The shift, from using circulating glucose to breaking down stored fat as a source of energy, usually happens over two to four days of eating fewer than 20 to 50 grams of carbohydrates per day. Keep in mind that this is a highly individualized process, and some people need a more restricted diet to start producing enough ketones. Because it lacks carbohydrates, a ketogenic diet is rich in proteins and fats. It typically includes plenty of meats, eggs, processed meats, sausages, cheeses, fish, nuts, butter, oils, seeds, and fibrous vegetables. Because it is so restrictive, it is really hard to follow over the long run. Carbohydrates normally account for at least 50% of the typical American diet. One of the main criticisms of this diet is that many people tend to eat too much protein and Continue reading >>
