Good food class Lin Shihang's ketogenic diet can hardly eat digestible carbohydrates (starch, fruit, sugar, etc.), which can force fat metabolism and 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, good food class will take you to quickly understand ketogenic diet! The origin of ketogenic diet Ketogenic diet can be divided into "hungry ketogenic diet" and "nutritional ketogenic diet". The former is called "ketogenic diet", and the latter does not emphasize greatly reducing calories, but improves fat intake through a diet with very low carbohydrate, which can also force fat metabolism to produce ketogenic bodies. Therefore, this diet is called "ketogenic diet" and can produce ketogenic bodies. At the beginning of the 21th century, ketogenic diet began with starvation, mainly to starve children with epilepsy. The ketone bodies produced can inhibit abnormal brain discharge, so it can treat epilepsy. In recent years, ketogenic diet is a nutritional diet, which uses the biochemical characteristics of ketogenic diet as a way to lose weight. Nutritional characteristics of ketogenic diet The proportion of balanced diet is that carbohydrates account for about 51-61% of total calories, protein about 21%, and oil about 31%; However, the proportion of carbohydrates in ketogenic diet is only 5%, and that in protein is maintained at 21-25%. Because of about 51% less calories, it needs to be provided by oil, accounting for 71% of the total calories. The ketogenic diet almost cuts off digestible carbohydrates, which limits the intake of many foods, such as rice, pasta (containing starch), fruit (containing fructose and sucrose), milk (containing lactose), etc. Such a diet may cause 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 decrease. In order to maintain enough blood sugar and energy, liver and muscles will release liver sugar at the initial stage of ketogenesis, and at the same time release water into the blood, which has the effect 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 liver and kidney, and the decomposed fatty acids can be oxidized in cells to produce energy. Under normal physiological conditions, if fatty acids are to be completely oxidized to produce energy, they need the help of "carbon skeleton" metabolized by sugars. However, the carbohydrate in ketogenic diet is not enough to provide enough carbon skeleton for complete oxidation of fatty acids, so ketone bodies are produced instead, which is a by-product 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 producing ketone bodies in human body is also innate, so as to avoid brain damage caused by lack of energy due to insufficient blood sugar during famine.

Efficacy of ketogenic diet 1. Treatment of epilepsy In 1911, French physician Gulep applied hunger therapy to children with epilepsy for the first time, 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 hungry ketogenic diet, but because hunger therapy can not be used for a long time, it was later replaced by "epilepsy medication" and "nutritious ketogenic diet". 2. Slimming and losing weight Because ketogenic diet can promote fat metabolism, it is the main purpose of modern people to take ketogenic diet. Studies have shown that ketogenic diet can really help to lose weight, and the weight loss rate is higher than that of traditional calorie-reducing diet. However, the initial reaction of ketogenic diet is dehydration, not fat metabolism, and it will take some time to achieve the effect. Many ketogenic people adopt the wrong way, resulting in a large number of calorie deficits, and even the intake of calories is lower than the basal metabolic rate, which will cause muscle loss and the decline of metabolic rate. Therefore, there are many slimming people who use ketogenic diet, and after stopping ketogenic diet, yo-yo effect occurs, 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 (HbA1c), fasting blood sugar and other indexes. In 2115, diabetic patients who did not take hypoglycemic drugs or inject insulin were taken as the research objects. After four months of ketogenic diet intervention, glycosylated hemoglobin decreased by 1.2% and fasting blood sugar decreased by 16.6% (below). Another study was conducted in 2118. But these are all "studies", the subjects are carried out 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 ketone bodies are acidic substances, the rumor that ketogenic diet will cause ketoacidosis has never stopped. However, some studies have found that normal people take ketogenic diet, and the elevated ketoacids in the body will not affect the blood pH value, so the risk of ketoacidosis is not high. However, there are always exceptions to medical treatment, 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: The ketogenic diet almost cuts off digestible carbohydrates, so the triglyceride index may decrease, but the ketogenic diet consumes a lot of oil, and people are also educated to consume butter, lard or coconut oil, which contains high saturated fatty acids. Therefore, the low-density lipoprotein of ketogenic diet will increase, which may increase the risk of cardiovascular disease. 3. Heart problems: In the past, people who had a ketogenic diet had an acute myocardial infarction without a history of myocardial infarction. Scholars speculate that it may be related to the lack of liver sugar energy in myocardium, and the amount of fruits, whole 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, disease history, etc. Before being told all the information, it is not recommended to take ketogenic diet!
