1, human digestive tract will secrete digestive juice in a certain period of time. On an empty stomach, the digestive tract is still crawling. At this time, there is no food to digest and only the inner wall of the gastrointestinal tract can be corroded. Without the stimulation of food, the digestive function will be weakened, and constipation will occur after a long time, causing digestive tract diseases.

2, a balanced diet, every kind of food needs to be eaten, especially foods containing protein, carbohydrates and fat, which can provide the nutrients needed by the human body. If you only eat one kind of food through an empty stomach diet, you can't meet the nutrition your body needs, which will lead to malnutrition.

3. The fasting diet will make people hungry for a long time, so that the body will use the stored fat and protein to supplement the needs of the human body, leading to the loss of collagen in the body, making your chest smaller and smaller, which will only make your figure worse and worse.

4, an empty stomach diet will destroy the digestive system and lead to malnutrition, and even make the body worse and worse.

Second, the benefits of the valley:

It is helpful to lose weight, reduce blood fat, reverse metabolic syndrome such as fatty liver and diabetes, and delay or reverse the occurrence of atherosclerosis. In the scientific process of breaking the valley, in addition to learning standardized guiding techniques, we should monitor blood sugar, blood pressure and heart rate in time every day, and observe all aspects of the body comprehensively and systematically.

Extended data:

It takes three weeks to go to the valley for a round trip. At first, you can eat some liquid food such as rice oil, and you should chew slowly. After three days, slowly eat some soft noodles and rice porridge with granules, and gradually add some fruits and vegetables, such as rice, oil cakes, big fish and big meat. It is best to take it within two weeks according to personal preference. Of course, it is best not to eat fried food.

It is necessary to give the stomach time to gradually cater to new eating habits and new food intake. Never eat hard as soon as you come out of the valley, let alone eat meat as soon as you come back. Don't eat hard and drink hard after returning to the valley, chew slowly, chew slowly after 36 bites, and eat 7 points full, otherwise it is of little significance to break the valley before.

It should be reminded that the valley-crossing period is generally 3 days, 7 days, 9 days, 1 1 day, 2 1 day or even longer. Professor Liu Changxi suggested not to exceed 1 1 day. For beginners, I suggest you break the grain three times in a row, once a month, for 7 days at a time. After mastering it, you can take a break at home once in a while.
