Nutrition experts don't agree with the theory of "fasting family". "Don't eat solid food, you can have a rest. This statement has no scientific basis and is taken for granted by fasting families, "Xu Diansong, a nutritionist at Nanjing First Hospital, told reporters. "Too frequent fasting is not only harmful to health, but also harmful to the body." He explained that whether the digestive system works or not has nothing to do with eating. Due to the long-term law of life, everyone has their own specific biological clock. Whenever it is time to eat, the digestive system such as gastrointestinal tract will automatically secrete digestive juice. If the human body does not take food to neutralize at this time, the digestive juice with strong acidity will accumulate in large quantities, corrode the inner wall of gastrointestinal tract and cause diseases. "Simply put, even if you don't eat, when you arrive at the meal, your stomach is still working." Therefore, frequent fasting is very harmful to the stomach.
However, Dr. Xu said that this "weekend fasting method" can still play a certain role if it is properly implemented. Because many people eat too much fat and carbohydrates every day, they choose to stop eating every two months 1 day to rest their intestines and stomach. Drinking yogurt and fruit and vegetable juice during fasting can supplement protein and vitamins, which will not lead to nutritional imbalance. If you stop eating every week, it will undoubtedly be harmful to your health.
At the same time, he also reminded the "fasting family" that it is best not to fast on Friday. "Friday is a working day. If you don't eat, your body won't take in carbohydrates, so you can't get energy supplement, and you don't have enough blood to supply your brain, "said Dr. Xu. "How can you be efficient when you go to work dizzy with hunger?"
The main members of the "weekend fasting family" are female white-collar workers and housewives. Therefore, Dr. Xu specially reminded "fasting women" that if they are on an empty stomach, they must pay attention to the female physiological cycle. Don't eat fast food during legal holidays. Because, at this time, a lot of iron is lost in the body. If you don't pay attention to adjust your diet, don't supplement nutrition in time, and stop eating blindly, it will do great harm to your body.
Experts disagree with fasting therapy.
But most experts don't agree with the practice of "fasting on weekends".
From the point of view of nutrition, a healthy lifestyle is to have three meals a day on time, a reasonable diet structure, a proper combination of vegetarian fruits and not overeating. The practice of "fasting on weekends", which destroys normal diet, has very limited effect on weight control. Fasting can never be used as a simple and harmless way to lose weight.
More importantly, fasting can cause a lot of physical discomfort. In addition to the original stored fat, protein, which is responsible for maintaining physiological function and immunity, will also be consumed, which is very dangerous for people with poor metabolic function.
Experts suggest that if the usual working meal is greasy, then you can choose some light foods for the weekend diet, such as vegetables, tofu, tomatoes, soup and so on. Those friends who want to lose weight through "fasting" had better not fast blindly. Only persistent diet control and exercise is the only way to get slim and healthy.
