Ordinary people's diet, the daily total calorie intake is generally 25~30 calories/kg body weight, and the proportion of the three major nutrients is generally:

Starch (carbohydrate) 55%~65%, fat 20%~30%, protein 10%~ 15% (normal diet).

Ketogenic diet is a diet with low calorie (at least 20% lower than the normal daily calorie requirement), moderate protein (1g/kg body weight/day), high fat and extremely low carbohydrate (less than 50g/ day), and the ratio of fat to carbohydrate is about 3: 1.

Simply and intuitively, this way of eating is to eat one or two meters of flour less every day, mainly meat, eggs and oil. I feel greasy fish and meat in front of me in my mind. )

This diet structure of ketogenic diet will induce metabolic changes in the body similar to hunger. Under normal circumstances, carbohydrates in the diet are directly converted into glucose in the body after digestion and absorption, which provides "fuel" and energy for the normal functions of various organs of the body, especially brain cells.

When the carbohydrate in the diet is extremely low and the total calories are not enough, the body mistakenly thinks that we are in a "hungry state", and the liver will mobilize the fat in the body and transform it into medium and long-chain fatty acids and various ketone bodies to replace glucose to provide energy for various organs.

Traditionally, ketogenic diet is regarded as the "last treatment" for intractable epilepsy that two or more antiepileptic drugs are ineffective. However, based on its efficacy, the expert group strongly suggested that ketogenic diet should be considered as soon as possible for intractable epilepsy.

In the investigation report, the expert group believes that ketogenic diet should be used after the average use of 2.6 antiepileptic drugs is ineffective.
