In recent years, the "ketogenic diet" has been enduring, claiming that as long as the dietary pattern is adjusted, it can quickly slim down, many people call it the safest green weight loss method, but in fact, the "ketogenic diet" was originally used to treat refractory epilepsy. Deng Yuhong, director of the Department of Clinical Nutrition at the Second Affiliated Hospital of Guangzhou Medical University, said that the "ketogenic diet" model may indeed make you lose weight, but it is not suitable for everyone, and it is used to lose weight or there are health risks.
The ketogenic diet was initially used to treat epilepsy
Deng Yuhong introduced that the "ketogenic diet" is a special and more extreme dietary pattern, that is, eating very low carbohydrates, high fat and appropriate protein.
Compared with the ordinary balanced dietary model, the particularity of the "ketogenic diet" is that its energy supply ratio changes significantly: carbohydrate energy supply accounts for only 4% to 17% of total calories, fat accounts for 60% to 90%, and protein accounts for 6% to 35%.
The peculiarity of the "ketogenic diet" is that its energy supply ratio changes significantly
During the implementation of the "ketogenic diet", staple foods (carbohydrates) are greatly reduced, forcing the body to decompose the glycogen stored in the muscles and liver to supply energy, and when the glycogen is gradually depleted, the body instead calls on fat tissue to undergo metabolic decomposition.
"Fat metabolism produces a class of substances called ketone bodies, which can also provide energy to make the body function properly. This is why it got its name ,'Ketogenic Diet'. Deng Yuhong further explained that in fact, the "ketogenic diet" first appeared in the early 1920s, and foreign doctors used this diet model for the first time to treat epilepsy patients, and the clinical effect was considerable.
According to reports, because the therapy is more strict on dietary control, even if it is used to treat refractory epilepsy, there are requirements for patient attributes, "My own experience is that at least the age of the child is carried out after 6 months of age, and it is safer after breastfeeding is over, after all, breast milk is the best source of nutrition for children." It is also required that the patient has no obvious impairment of cardiac, liver and kidney function, and no disorders of fat metabolism, such as pyruvate carboxylase deficiency and organic aciduria. Kidney stones are also relative contraindications. ”
It has a weight-loss effect, but there are health risks
Since not all epilepsy patients are suitable for the "ketogenic diet", is there also a risk for ordinary people to lose weight?
Deng Yuhong said that clinical observations have found that some people have indeed lost weight after following the "ketogenic diet" method, but this does not mean that the "ketogenic diet" is safe. Therefore, doctors do not promote such special, extreme dietary patterns. First of all, if too many ketone bodies are generated, it may cause ketoacidosis, and uncomfortable symptoms such as headache, dizziness, fatigue, and drowsiness will occur.
Ketogenic weight loss er: oil is unpalatable, rice noodles are not allowed to eat, then do not eat meat
"In addition, high fat means eating more fat, including liquid fats, such as peanut oil, corn oil, rapeseed oil, olive oil, etc., as well as solid fats such as lard, butter, etc. But the above foods are difficult or long-term for ordinary people to eat, because this diet mode requires that they must eat less carbohydrates, so most people will go to the other extreme: high protein intake, eat a lot of meat, especially from red meat and processed meat. Deng Yuhong said that such a way of eating, one is to lead to impaired intestinal function, and the current medical community is also generally believed to increase the risk of colon cancer. Second, the high-protein "ketogenic diet" will also accelerate kidney failure in patients with kidney disease.
In the actual operation process, in order to achieve the purpose of rapid weight loss, many people will even refuse to eat any carbohydrate foods, so "simple and rude" resulting in an unbalanced proportion of eating, and there will be malnutrition or even more serious health problems. If high-fat foods are strictly enforced, it is bound to bring about the risk of excessive intake of saturated fatty acids and increase the risk of cardiovascular disease.
