Updated Sep 22nd, — Written by Craig Clarke. Medical review by Dr. The ketogenic diet has been rising in popularity, and for good reason — it is simple and yields significant results. Whether you want to lose fat, increase energy, enhance brain health, improve your blood sugar levels, or improve your overall health, keto may be the diet you are looking for. However, before we learn how to start a keto diet, we must develop a deeper understanding of what it is and why it is so effective. Knowing the what and why behind this way of eating plays an integral role in your keto diet success as well as knowing how to get started. The keto diet can be described in many different ways, but the most common definition is that it is a high-fat, low-carb, low-to-moderate protein diet. Ketosis is a metabolic state in which your body is consistently using and burning a highly efficient alternative fuel called ketones. To produce ketones and enter ketosis, we must continually trigger a process in the liver called ketogenesis. The healthiest way to do this is by limiting carb consumption more than any other low carb diet.
Edinburgh: Royal College of Physicians; This is mainly water weight. These ketone bodies enter the brain and partially substitute for blood glucose as a source of energy.
A ketogenic diet for beginners By Dr. Andreas Eenfeldt, MD, medical review by Dr. Get started with our visual guides, recipes, meal plans, and simple 2-week Get Started program. What is a keto diet? The keto diet is a very low-carb, higher-fat diet. While you eat far fewer carbohydrates on a keto diet, you maintain moderate protein consumption and may increase your intake of fat. The reduction in carb intake puts your body in a metabolic state called ketosis, where fat, from your diet and from your body, is burned for energy. Watch the entire 8-part video course. When you eat very few carbs or very few calories, your liver produces ketones from fat.

The ketogenic diet is a high- fat, adequate- protein, low-carbohydrate diet that in medicine is used mainly to treat hard-to-control refractory epilepsy in children. The diet forces the body to burn fats rather than carbohydrates. Normally carbohydrates in food are converted into glucose, which is then transported around the body and is important in fueling brain function. But if little carbohydrate remains in the diet, the liver converts fat into fatty acids and ketone bodies, the latter passing into the brain and replacing glucose as an energy source. An elevated level of ketone bodies in the blood a state called ketosis eventually lowers the frequency of epileptic seizures. 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 developed for treatment of paediatric epilepsy in the s and was widely used into the next decade, but its popularity waned with the introduction of effective anticonvulsant medications. This classic ketogenic diet contains a ratio by weight of fat to combined protein and carbohydrate. This is achieved by excluding high-carbohydrate foods such as starchy fruits and vegetables, bread, pasta, grains, and sugar, while increasing the consumption of foods high in fat such as nuts, cream, and butter.
