First, we don't violate the laws of nature. This is because today we are rich in food, eat too much, eat too well, eat too much, have overnutrition, have too many calories, have too thick fat, are seriously overweight, and have too much pressure, which leads to blockage of meridians, obstruction of qi and blood, physiological and psychological disorders, fatty liver, diabetes, hyperglycemia, hypertension, hyperlipidemia, high uric acid and high cholesterol. It is consistent with the comprehensive, balanced and reasonable nutrition advocated by traditional Chinese medicine and the balance between yin and yang emphasized by modern nutrition. If one side is over-nourished, it is necessary to eat less and not eat for a period of time in order to achieve the balance of the body, which is in line with the natural law of medical balance theory and the law of objective dialectics. Modern scientific facts have proved that if he is allowed to eat and drink in the sea, he will be overnourished, obese and three high, which will lead to wealth and other diseases. But if you don't eat rice for a short time, you can lose weight, remove excess fat and garbage, and balance your physiological functions. This is obviously a way to follow human energy metabolism, maintain relative balance and conform to the laws of nature! There is no denying that food is the most important thing for people, and people need nutrition when they are alive. If we leave the food supply for a long time, it means death. The problem is that we are overnourished and eat too much today. If we don't control our food intake, it will also lead to illness or death, so that modern people jokingly say, "Today, many people are not starving to death, but dying." And not eating for a short time is precisely to maintain the balance of human physiological functions, which fully shows that it is in line with the laws of nature! Therefore, some experts say that "people can only survive by raising grain after birth, and the practice of avoiding grain violates this principle, which will lead to imbalance between yin and yang and even death." This is obviously a fantasy, taken out of context. Due to the balance of yin and yang and overnutrition, we know that we are out of balance. Why don't we take measures? If you don't eat it for a short time, it will keep its function relatively balanced! There are experts in nutrition, who have never broken the valley, nor have they personally practiced and experienced it. Just from the perspective of nutrition, "a healthy body needs enough protein, fat and sugar to maintain normal operation. Long-term penetration of grain will affect the normal operation of gastrointestinal tract, intestinal permeability, secretion of digestive juice and absorption of nutrients, which will easily lead to metabolic disorders, even gastritis, gastric ulcer and other diseases. To stay healthy, it is still recommended to follow a reasonable diet. " You see, first of all, he doesn't know that crossing the valley is a systematic operation method. He thinks that crossing the valley means not eating, but he doesn't know how to adjust mental energy, control thoughts, comfort methods, take energy to get gas, swallow gas field and so on. Secondly, I don't know how much extra energy is stored in the body to maintain the energy consumed by the human body every day without food. Knowing that there is overnutrition, won't it aggravate the condition if you continue to eat these nutritious things? Thirdly, avoiding the valley is not to keep you from eating for a long time, but to avoid the valley for a period of time. This is a process of adjusting the balance, not to stop eating from now on. This cannot be confused.
