Keto Diet is an eating plan that depletes our body of its sugar reserves, and as a result, stored fat starts to break down for energy, and burning fat by the body eventually leads to weight loss and other health benefits. For that purpose, Keto Diet replaces the intake of carbohydrates (sugars, starches, etc.) with healthy fats, while leaving the intake of proteins on an adequate level. A ketogenic diet typically includes plenty of meats, eggs, processed meats, sausages, cheeses, fish, nuts, butter, oils, seeds, and fibrous vegetables. The goal of the ketogenic diet is to get more calories from fat than from carbs, or in other words, starve us on sugar. This forces the production of molecules called ketones that the body uses for fuel and their elevated level in the blood induced by carbohydrate restriction is known as a nutritional ketosis state. It usually takes from two to four days of eating fewer than 50 grams of carbohydrates per day to reach ketosis, and then most body cells will use ketones to generate energy until we start eating carbs again.
Ketosis is being investigated for a growing number of medical conditions like diabetes, neurological diseases, and even anti-tumor activity in cancer patients, however clinical recommendations for these conditions cannot yet be made based on the current level of scientific evidence. The research on the ketogenic diet shows many beneficial metabolic changes in the short-term, while its restrictiveness is hard to follow over the long run with controversial health benefits. Along with weight loss, health parameters associated with excess weight can be improved, such as insulin resistance, high blood pressure, blood sugar, and elevated cholesterol among many others. Therefore it is recommended to consult with a physician to closely monitor any biochemical changes after starting the keto diet regimen, to produce adequate health benefits while preventing nutritional deficiencies or other health complications.
