There is a folk saying in our country that "eat less incense, eat more hurt" and "hunger does not overeat, thirst does not binge drink". People have done such an experiment: rats were randomly divided into two groups. One group restricted their diet and only ate eight points full. The other group ate for free and helped themselves. The life span of rats in the two groups was observed. The end result is that mice that eat eight full points live longer. American researchers have observed worms, mice and monkeys, and found that the daily food supply is only 70% of the total calories, and its life span is 30% longer than that of similar people who supply enough calories. So do we humans. Fat people live longer. Bama Yao Autonomous County in Guangxi is located in the mountainous area in the northern suburb of Nanning. Although its economy is underdeveloped, it is a longevity county with many elderly people over 100 years old. One of the ways for them to keep fit is to eat only eight points full, and they are mainly vegetarian. Although there are many acquired factors for longevity, there are also many ways to keep in good health, but the methods of keeping in good health are worth emulating.

There is a folk saying in our country that "eat less incense, eat more hurt" and "hunger does not overeat, thirst does not binge drink". There is a saying in "Qin Shou's New Book on Pension" that "people who respect the elderly cannot be full". Neijing emphasizes that "eat moderately ... so that you can be integrated with the spirit and live to the end of your life when you are 100 years old". These are the summary of predecessors' long-term health care experience. If you eat too many calories, your body will be obese, the chances of getting "rich disease" will increase, and your natural life will be shortened. At present, there are many obese tumor patients, which brings trouble to the treatment. However, why limiting calorie intake will prolong life to a certain extent, and its mechanism needs further study. Some people imagine that when the human body feels that the heat provided is insufficient, it can slow down its metabolism and reserve some energy. When metabolism slows down, less poisons and wastes are produced, and the amount of self-absorption and the burden of detoxification are correspondingly reduced, thus reducing vigorous metabolism and hyperactive physiological processes. Therefore, in the process of relatively low level metabolism, catabolism is relatively reduced, thus prolonging life. These hypotheses need to be further verified, and the conclusions of animal experiments may not be completely in line with human beings. However, the enlightenment that you can live long after eating is still worthy of attention and discussion.

How to achieve "eight points full";

First of all, we must be persistent, not wavering in the face of food, and take the initiative to leave the table before we are full;

Drinking soup or porridge before meals will lead to satiety in advance;

Prevent overeating when you are hungry.

Most obese people overeat, and often overeat. This is because fat cells can secrete substances that stimulate appetite, and fatty foods can stimulate appetite. The bigger you eat, the harder it is to feel full. So the more you eat, the more you eat, forming a vicious circle. There is a saying in Chinese medicine that "the stomach is full of fire and the valley is hungry", and it is considered that a good appetite is also a pathological state.

Eating eight points full is beneficial to human health, but it is also principled and should be treated flexibly according to your own situation.
