A ketogenic diet with a good appetite for forests can hardly eat digestible carbohydrates (starch, fruit, sugar, etc.). ), can force fat metabolism to achieve slimming effect, so ketogenic diet has become a trendy diet in recent years. In addition, ketogenic diet may also have the benefits of regulating blood sugar, but it has health concerns such as raising blood lipid and ketoacidosis. In this topic, the good food class will take you to quickly understand the ketogenic diet! Ketogenic diet can be divided into "hungry ketogenic diet" and "nutritious ketogenic diet" The former is called "ketogenic diet", and the latter does not emphasize the drastic reduction of calories, but increases fat intake through a diet with extremely low carbohydrate content, which can also force fat metabolism to produce ketogenic bodies. Therefore, this diet is called "ketogenic diet", which can produce ketogenic bodies. At the beginning of the 20th century, ketogenic diet started from starvation, mainly to starve children with epilepsy. The ketone body produced can inhibit abnormal brain discharge, so it can treat epilepsy. In recent years, ketogenic diet is a nutritious diet, and the biochemical characteristics of ketogenic diet are used as a way to lose weight. Nutritional characteristics of ketogenic diet The proportion of balanced diet is that carbohydrates account for about 50-60% of total calories, protein accounts for about 20%, and oil accounts for about 30%; However, the proportion of carbohydrates in ketogenic diet is only 5%, which is maintained at 20-25% in protein. Because the heat is about 50% less, it needs to be provided by oil, accounting for 70% of the total heat. Ketogenic diet almost cuts off digestible carbohydrates and limits the intake of many foods, such as rice, pasta (containing starch), fruit (containing fructose and sucrose) and milk (containing lactose). Such a diet may lead to the deficiency of micronutrients. At the end of this article, a daily ketogenic menu will be attached for your reference. Biochemical Mechanism of Ketogenic Diet Ketogenic diet almost cuts off digestible carbohydrates, so blood sugar will be lowered. In order to maintain enough blood sugar and energy, the liver and muscles will release liver sugar in the early stage of ketogenesis, and at the same time release water into the blood, which plays the role of diuresis and dehydration. Then, in order to provide glycerol as a raw material for sugar regeneration, fat begins to decompose in large quantities, liver sugar can produce blood sugar in the liver and kidneys, and the decomposed fatty acids can be oxidized in cells to produce energy. Under normal physiological conditions, the complete oxidation of fatty acids to produce energy requires the help of the "carbon skeleton" of sugar metabolism. However, carbohydrates in ketogenic diet are not enough to provide enough carbon skeleton for complete oxidation of fatty acids, so ketone bodies are produced instead, which are by-products of fat metabolism and the source of the name of ketogenic diet. Because nerve cells only use blood sugar and ketone bodies, the mechanism of human body producing ketone bodies is also innate, so as to avoid brain damage caused by insufficient energy caused by insufficient blood sugar during famine.

The effect of ketogenic diet is 1. Treatment of epilepsy 19 1 1 2000, the French doctor Gulop first applied hunger therapy to children with epilepsy, and found that the incidence of children with epilepsy decreased. Subsequent studies have found that ketone bodies produced by hunger can promote the synthesis of GABA in the brain. GABA is an inhibitory neurotransmitter. After passing through ketone bodies, the increased GABA can reduce abnormal discharges in the brain and reduce the incidence of epilepsy. This is a hunger ketogenic diet, but because hunger therapy can not be used for a long time, it was later replaced by "epileptic drug therapy" and "nutritious ketogenic diet" 2. Slimming and losing weight Because ketogenic diet can promote fat metabolism, eating ketogenic diet is the main purpose of modern people. Studies have shown that ketogenic diet can really help to lose weight, and the weight loss rate is higher than the traditional calorie-reducing diet. But the initial reaction of ketogenic diet is dehydration, not fat metabolism, and it takes some time to achieve the effect. Many ketogenic people adopt the wrong way, resulting in a large number of calories shortage, or even the intake of calories is lower than the basal metabolic rate, which will lead to muscle loss and decreased metabolic rate. Therefore, many people who lose weight use ketogenic diet. After stopping ketogenic diet, there will be yo-yo effect, and their weight will recover quickly, even exceeding the weight before losing weight. 3. Regulating blood sugar Many studies show that ketogenic diet is helpful to improve glycosylated hemoglobin (HbA 1c), fasting blood sugar and other indicators. Diabetic patients who did not take hypoglycemic drugs or inject insulin in 2005 were taken as the research object. After four months of ketogenic diet intervention, glycosylated hemoglobin decreased by 65438 0.2% and fasting blood glucose decreased by 65438 0.6. Another study was conducted in 2008. After six months of ketogenic intervention, glycosylated hemoglobin decreased by 65438 0.5% and fasting blood glucose decreased by 65438 09.9 mg/dl (link). But these are all "studies", the subjects are under supervision, and the patients' diet, medication and insulin are well controlled. In real life, diabetics may take drugs and insulin, so diabetics should communicate with doctors and nutritionists to discuss the feasibility before adopting ketogenic diet. Side effects of ketogenic diet 1. Ketoacidosis: Because ketogenic body is acidic, the rumor that ketogenic diet will cause ketoacidosis has never stopped. However, some studies have found that normal people take ketogenic diet, and the increase of ketonic acid in the body will not affect the blood pH value, so the risk of ketoacidosis is not high. However, there are always exceptions to drug therapy, and there are still cases of ketoacidosis caused by eating ketogenic diet (link). Therefore, if dizziness, vomiting, drowsiness and other phenomena occur when eating ketogenic diet, it is necessary to stop ketogenic diet and seek medical treatment. 2. Blood lipid problem: Ketogenic diet almost cuts off digestible carbohydrates, so the triglyceride index may decrease, but ketogenic diet consumes a lot of oil, and people are also educated to eat butter, lard or coconut oil, which contains high saturated fatty acids. Therefore, the low-density lipoprotein in ketogenic diet will increase, which may increase the risk of cardiovascular disease. 3. Heart problems: In the past, people who ate ketogenic diet had acute myocardial infarction, but had no history of myocardial infarction. Scholars speculate that it may be related to the lack of liver sugar energy in myocardium. The amount of fruits, coarse grains and vegetables of ketogenic dieters is limited, which reduces the intake of antioxidant nutrients and micronutrients and affects the function of the heart. Ketogenic diet has many hidden risks, so before taking ketogenic diet, it is recommended to find professionals, such as doctors and nutritionists, to evaluate their health status, such as blood sugar, blood lipids and medical history. It is not recommended to take ketogenic diet until you are told all the information! How to eat ketogenic diet?
