A ketogenic diet is a low-carb, high-fat, adequate protein diet that was initially developed in the ’20s to help people with neurological diseases such as epilepsy. On a ketogenic diet, you’re attempting to get your body into ketosis, which is a metabolic state where you begin to use fat as your primary source of fuel. What Is Ketosis? Usually, our bodies rely on carbs as the first source of energy. Carbs are broken down into sugar when you eat them, leading to the production of insulin, a hormone that tells your cells to use the sugar for energy now or store it for use later. “When you only eat a very limited amount of carbs, your body breaks down fatty acids from fat stores and forms ketones, which are released into the bloodstream by the liver,” says Alissa Rumsey M.S., R.D., C.S.C.S., and spokesperson for the Academy of Nutrition and Dietetics. “Ketosis occurs when blood ketones are higher than normal.” Ketosis is basically a side effect of fasting. To trigger ketosis, you must fast for about three days, and a proven way to do that is to decrease the amount of carbohydrates in your diet and increase the amount of fat, says Rumsey. So a ketogenic diet — one that is very high in fat with some protein and very little carbohydrates — can be used to get your body into ketosis. To start ketosis and keep it going, you’ll have to eat less than 30 to 40 grams of carbohydrate per day, which is about 5 percent of your overall calories for the day. There are three main types of ketogenic diets 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 >>
What Could Be A Good Paleo Diet For A 22 Year Old Vegetarian Indian Male?
I'm a vegetarian (Gujarati) in a similar situation. From what I've read, researched, practiced and observed, here's my spot of advice. (This answer will be disjointed since I'm typing on the go here.) Fitness is 80% what goes in you (the food you eat) and 20% the energy you expend (workouts). Given that you currently follow a regular low-to-medium intensity cardio workout routine (I'm assuming you're not sprinting 4,000 metres), the best option would be to follow a low-carb diet, keeping carbs to less than 50g/day. This will put your body in a state of ketosis, where it burns ketones for energy instead of carbohydrates. To put this in perspective, let's back up a little to understand how the body works. Your body burns different sources of nutrients for the energy it needs in the following order of preference - carbs (including sugars), proteins and fats. Carbs, especially sugars are the easiest to burn, while fats take the most energy, time and effort. So when you eat something, the body immediately looks for the laziest option - sugar (this explains the transient 'sugar-high' you sometimes get). After this, the body prefers to burn proteins, and last of all come the fats. By the time it's the turn of the fats to be used, our diet ensures that we already have all the energy we need from Carbs and Proteins, and the Fats are left to rot in various parts of the body, undigested. I've come to understand that contrary to popular belief, it's not the fats that make us fat, but the carbs that we have WITH fats, that end up making us fat. So don't let the name 'fats' fool you. Humans had evolved to similar to what we are now, since about 200,000 years ago. Until approximately 10,000 years ago, we were basically hunter gatherers, running to catch prey and to save our asses and Continue reading >>
Should Endurance Athletes Go Keto? Ketosis And Ketogenic Diets For Endurance Athletes
When it comes to weight loss and endurance performance, dietary ketosis is the strategy everyone is asking about this year. On the surface, ketosis or a ketogenic diet offers everything an endurance athlete could dream of: endless energy, freedom from bonking, and an efficient pathway to weight loss. The diet has been all over mainstream magazines, it’s the subject of several new books, and the supplement companies have already jumped in with new products and a ton of marketing dollars. So, is it time for cyclists, triathletes, and runners to go Keto? First, a refresher course on what a ketogenic diet is. To achieve dietary or nutritional ketosis you need to severely restrict carbohydrate intake (fewer than 50 grams of CHO/day) so the body transitions to using ketones for fueling muscles and the brain. Ketones are produced from fat, which is why nutritional ketosis is so appealing to sedentary people as a weight loss solution. It’s appealing to athletes because we have a virtually unlimited reserve of fat calories to pull from but can only store 1600-2000 calories worth of carbohydrate in muscles, blood, and the liver. An athlete fueled by ketones would be theoretically “bonk-proof”, since bonking is the result of running low on blood glucose. [blog_promo promo_categories=”coaching” ids=”” /] Dietary ketosis for athletes is one of the most hotly contested subjects right now. Proponents point to the metabolic advantage of relying on fat instead of carbohydrate, and critics point out the physiological limitations of eliminating carbohydrate as a fuel for performance. You’ll find bias in both groups, either because scientists and coaches (including me) have been in the high-carbohydrate camp for many years, or because there’s a lot of money to be made b 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 >>
Ketogenic Diets - What Are They? Do They Work?
What would you say if I told you that you could supercharge your energy levels with a switch to your diet? How about lose fat or bulk up using the same diet? Would you like to eat the foods that are considered taboo? Ketogenic Diets - What Are They? Do They Work? What would you say if I told you that you could supercharge your energy levels with a switch to your diet? How about lose fat or bulk up using the same diet? Would you like to eat the foods that are considered taboo? You know... The good foods, the ones with all the fats that really taste good. We are speaking of ketogenic diets (or keto for short). Countless books have been written on this very subject and yet the world does not understand the value of this diet. I keep hearing the same comments: "Man that diet is bad for you." "You will have excessive cholesterol and probably have a heart attack." Where does this come from? A common lack of knowledge! Most of the time we fear that which we don't understand, so we are here to shed some light on the subject and hopefully leave you with a better understanding about this diet. Fitnessman and I have decided it was time to "school" some of you on the effects and ease of this diet. This is the first time we have ever done anything like this together so it should prove to be interesting. Fitnessman is highly schooled on the subject of Ketogenic diets. He has a degree in nutrition and is a major contributor in the Bodybuilding.com forum. When Fitnessman talks we all stop and listen! On with the article... The Problem The most common problem today is what we eat. Modern man seems to have gotten so wrapped up in processing stuff that it actually became bad for us to eat. Many years ago man ate meat! This was his diet. He would kiss his family goodbye and go off in searc Continue reading >>
Does The Controversial Ketogenic Diet Really Work? Dietitians Give Their Verdict On The Low Carb High Fat Program Beloved By Celebrities
Favoured by the likes of Kim Kardashian and Gwyneth Paltrow for its rapid results, the Ketogenic Diet has been making headlines non-stop over the past 12 months. The low carbohydrate, high fat program sees participants eat moderate protein and receive the majority of their energy intake from fat. But does it really work? The Dietitians Association of Australia recently weighed in on the controversial diet and revealed the three things people need to consider before jumping on board the Keto bandwagon. The Dietitians Association of Australia recently weighed in on the controversial diet and revealed the three things people need to consider before jumping on board the Keto bandwagon In a recent media alert, the DAA first explained the thinking behind the program and how it works. 'As fat is the main source of energy being consumed, the body must then use this (that is, break it down) as its main energy source or "fuel",' they explained. 'When dietary fat is metabolised for energy, by-products called "ketone bodies" (molecules that are made by the liver from fatty acids) are produced which are used up by the body’s tissues, muscles and the brain. This process is known as "ketosis". 'The body can enter ketosis during times of severe energy restriction (such as during fasting or starvation) or prolonged intense exercise, or when carbohydrate intake is reduced to around 50g per day, or less – the equivalent of around two slices of bread, and a banana.' While there are many low carb, high fat diets available, the Keto Diet remains 'proportionately lower in carbohydrates' at around 20 to 50 grams per day to keep the body 'in a state of ketosis'. When it comes to weight loss, the DAA says those who follow a Keto Diet will 'undoubtedly result in short-term weight loss'. This, Continue reading >>
Do I Have To Stay At 20g Of Carbs A Day To Lose Weight And Enter Ketosis?
While in ketosis, your body effectively uses fat for fuel. In general, the daily intake of net carbs required to enter ketosis could vary from 20 to 100 grams per day (and very rarely over 100 grams per day). Most people, who have experienced ketosis, claim to have reached that state at about 20-50 grams of net carbs per day. I'd suggest you start at 20-30 grams and see how you can adjust it for your needs. There are two ways to find your ideal net carbs intake: Low to high method Start from a low level of net carbs to ensure you quickly enter ketosis (~ 20 grams of net carbs per day). When you detect ketosis after about 2-3 days, start adding net carbs (about 5 grams each week) until you detect a very low-level or no ketones (using Ketostix or blood ketone meter). This is usually the most reliable and quickest way to discover your net carbs limit. It could be a bit hard the first couple of days, as you have to give up almost all carbs from one day to another but it will be worth it. This method is highly recommended. High to low method Assuming you're not in ketosis, start from a relatively high level of net carbs (~ 50 grams) and keep reducing (about 5 grams each week) until you detect presence of ketones. This is a less difficult approach but not recommended, as you may spend a long time out of ketosis before you find you net carbs limit. If you can't see any ketones, be patient. It typically takes 2-3 days for your body to deplete glycogen stores, so don't expect to be in ketosis after just a day of low-carb. Remember, ketosis is a favourable condition and an indication that your body uses fat for fuel but you can lose weight even without being in ketosis. Diet high in fat, adequate in protein and low in carbohydrates is naturally sating, making you less hungry and, Continue reading >>
What This Dietitian Has To Say About The Ketogenic Diet Will Surprise You
You'll lose weight, even though bacon is on the menu, for starters. This article initially appeared on news.com.au and has been republished here with permission. If you have any interest in the world of diet and nutrition chances are you would have seen reference to a ‘keto’, or low carb, high fat (LCHF) approach to diets and weight loss.Used clinically for many years, specifically in the area of epilepsy where it is used to help reduce seizures, ketogenic diets are also known for their relatively quick weight loss outcomes. Not a new area of nutrition but one that has become increasingly popular in recent years, the question is, ‘is a ketogenic diet the right diet for you?’ Ketogenic diets refer to diets that are particularly low in carbohydrates (ranging from 5-20%, or 20-50g of total carbohydrates and high in fats (up to 75% in total fat). This is as opposed to standard ‘diets’ which contain 30-50% carbohydrates and just 30% fat or less. Diets that are much lower in carbohydrate than the muscles and the brain typically need to function shift the body into a state known as ‘ketosis’ in which fat stores in the body are broken down into ketones which fuel the muscles and the brain in place of the carbohydrates when they are in limited supply. The result is enhanced fat burning and relatively quick weight loss as compared to a traditional dietary approaches. There is no evidence to show that keto diets are damaging to the body. In fact, with their superior weight loss and associated reductions in inflammation in the body, there are a number of benefits, particularly for individuals with high blood glucose levels, fatty liver and significant amounts of weight to lose. The primary issue with keto diets is that the total amount of carbohydrate consumed needs Continue reading >>

How Does Ketosis Work?
The Keto Diet is a diet that focuses on eating foods high in fat, moderate in protein and low in carbs. The diet is said to help with rapid weight loss by forcing your body into a deprived state which gets it burning this fat for energy. Click to read more on the Keto Diet. You may have heard the word ‘Ketosis’ batted around when hearing about this diet too. But how does Ketosis work I hear you say and what on earth is Ketosis? When you are eating a diet rich in carbs or high in sugar, these carbs and sugars are your main source of energy and your body converts them into glucose. Any glucose leftover that has not been burnt is stored in the liver for when your body might need it as glycogen. Once this extra storage space has been taken up, anything that doesn’t fit into storage gets used as fat or tissue in the body. This over time adds to weight gain and fat around the body. When thinking about giving our body energy to function on a daily basis, carbs, although normally the main source of energy, are not the most effective ways of putting fuel into our bodies. Believe it or not, when some people lower their carb intake and increase their fats on a Keto diet, they actually feel like they have more energy and don’t feel sluggish and tired like they did when they were eating more carbs. When our bodies eat more fat on a Keto diet, it’s been proven that the energy provided is actually ‘better’. It can sometimes be hard to get our body to take this ‘better’ energy when we eat carbs, as when we eat more carbs than fat, our bodies take the easy route and go for glycogen over fat fuel as it takes less energy to burn carbs than fats and is therefore easier for the body. If however there is little to no glycogen in the body to be burnt, our bodies have no othe Continue reading >>
Which Foods Or Supplements Work To Promote Ketosis?
You’re starting to see exogenous ketone supplements hit the market, but it’s important to note that these supplements do not enhance the production of ketones in your body. It is simply a way of increasing the amount of ketones so to speak. The only two things that I am aware of that promote the production of ketones are coconut oil and MCT oil. Coconut oil contains MCT’s (medium chain triglycerides), but isn’t as potent as MCT oil. Some people, like myself, can’t handle MCT oil but are okay with coconut oil. Continue reading >>
What is the ketogenic diet? The "classic" ketogenic diet is a special high-fat, low-carbohydrate diet that helps to control seizures in some people with epilepsy. It is prescribed by a physician and carefully monitored by a dietitian. It is usually used in children with seizures that do not respond to medications. It is stricter than the modified Atkins diet, requiring careful measurements of calories, fluids, and proteins. Foods are weighed and measured. The name ketogenic means that it produces ketones in the body. (keto = ketone; genic = producing) Ketones are formed when the body uses fat for its source of energy. Usually the body uses carbohydrates (such as sugar, bread, pasta) for its fuel. Because the ketogenic diet is very low in carbohydrates, fats become the primary fuel instead. The body can work very well on ketones (and fats). Ketones are not dangerous. They can be detected in the urine, blood, and breath. Ketones are one of the more likely mechanisms of action of the diet, with higher ketone levels often leading to improved seizure control. However, there are many other theories for why the diet will work. Who will it help? Doctors usually recommend the ketogenic diet for children whose seizures have not responded to several different seizure medicines. The classic diet is usually not recommended for adults, mostly because the restricted food choices make it hard to follow. However, the modified Atkins diet does work well. This also should be done with a good team of adult neurologists and dietitians. The ketogenic diet has been shown in many studies to be particularly helpful for some epilepsy conditions. These include infantile spasms, Rett syndrome, tuberous sclerosis complex, Dravet syndrome, Doose syndrome, and GLUT-1 deficiency. Using a formula-only Continue reading >>
Ketogenic Diet For Obesity: Friend Or Foe?
Go to: 3. The Physiology of Ketosis After a few days of fasting or a drastically reduced carbohydrate diet (below 20 g per day), the body’s glucose reserves become insufficient for the production of oxaloacetate for normal fat oxidation in the Krebs cycle and for the supply of glucose to the central nervous system (CNS) [19,20,21,22]. Regarding the first issue, oxaloacetate is relatively unstable at body temperature, thus it is necessary (a minimal amount of oxaloacetate is required for an optimal functioning of the Krebs cycle) to supply the tricarboxylic acid cycle with oxaloacetate derived from glucose through ATP dependent carboxylation of pyruvic acid by pyruvate carboxylase . Regarding the second issue, the CNS cannot use fatty acids as an energy source (because they do not cross the blood-brain barrier), thus glucose is ordinarily the sole fuel for the human brain . After 3–4 days of fasting or a very low carbohydrate diet the CNS needs an alternative energy source [19,20,21,22] and this is derived from the overproduction of acetyl-CoA which leads to the production of so-called ketone bodies (KB): acetoacetate (AcAc), β-hydroxybutyric acid (BHB) and acetone (Figure 1 and Figure 2). This process is called ketogenesis and occurs principally in the mitochondrial matrix in the liver . It is important to underline that the liver produces ketone bodies, but is unable to utilize them because the absence of the enzyme 3-ketoacyl CoA transferase required to convert acetoacetate into acetoacetyl-CoA. Even though the main ketone body produced in the liver is acetoacetate, the primary circulating ketone is β-hydroxybutyrate that is not, strictly speaking, a ketone body because the ketone moiety has been reduced to a hydroxyl group. Under normal conditions t Continue reading >>

Ketosis: What Is Ketosis?
Ketosis is a normal metabolic process. When the body does not have enough glucose for energy, it burns stored fats instead; this results in a build-up of acids called ketones within the body. Some people encourage ketosis by following a diet called the ketogenic or low-carb diet. The aim of the diet is to try and burn unwanted fat by forcing the body to rely on fat for energy, rather than carbohydrates. Ketosis is also commonly observed in patients with diabetes, as the process can occur if the body does not have enough insulin or is not using insulin correctly. Problems associated with extreme levels of ketosis are more likely to develop in patients with type 1 diabetes compared with type 2 diabetes patients. Ketosis occurs when the body does not have sufficient access to its primary fuel source, glucose. Ketosis describes a condition where fat stores are broken down to produce energy, which also produces ketones, a type of acid. As ketone levels rise, the acidity of the blood also increases, leading to ketoacidosis, a serious condition that can prove fatal. People with type 1 diabetes are more likely to develop ketoacidosis, for which emergency medical treatment is required to avoid or treat diabetic coma. Some people follow a ketogenic (low-carb) diet to try to lose weight by forcing the body to burn fat stores. What is ketosis? In normal circumstances, the body's cells use glucose as their primary form of energy. Glucose is typically derived from dietary carbohydrates, including: sugar - such as fruits and milk or yogurt starchy foods - such as bread and pasta The body breaks these down into simple sugars. Glucose can either be used to fuel the body or be stored in the liver and muscles as glycogen. If there is not enough glucose available to meet energy demands, th Continue reading >>
This article is about a dietary therapy for epilepsy. For information on ketogenic diets as a lifestyle choice or for weight loss, see Low-carbohydrate diet and No-carbohydrate diet. The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet that in medicine is used primarily to treat difficult-to-control (refractory) epilepsy in children. The diet forces the body to burn fats rather than carbohydrates. Normally, the carbohydrates contained in food are converted into glucose, which is then transported around the body and is particularly important in fueling brain-function. However, if there is very little carbohydrate in the diet, the liver converts fat into fatty acids and ketone bodies. The ketone bodies pass into the brain and replace glucose as an energy source. An elevated level of ketone bodies in the blood, a state known as ketosis, leads to a reduction in the frequency of epileptic seizures. Almost half of children, and young people, with epilepsy who have tried some form of this diet saw the number of seizures drop by at least half, and the effect persists even after discontinuing the diet. There is some evidence that adults with epilepsy may benefit from the diet, and that a less strict regimen, such as a modified Atkins diet, is similarly effective. The most common adverse effect is constipation, affecting about 30% of patients—this was due to fluid restriction, which was once a feature of the diet, but this led to increased risk of kidney stones, and is no longer considered beneficial. The original therapeutic diet for paediatric epilepsy provides just enough protein for body growth and repair, and sufficient calories[Note 1] to maintain the correct weight for age and height. The classic therapeutic ketogenic diet was develope Continue reading >>
