First, eating less can reduce the burden on the stomach. Excessive intake of protein and fat will overload the digestive system and easily lead to indigestion.
In this way, undigested food stays in the intestine for a long time, which will produce a lot of toxins and carcinogens. These toxins and carcinogens are not only easy to make people suffer from intestinal diseases, but also absorbed by the intestine, damaging the central nervous system through the heart-brain barrier and aging people.
Second, satiety makes brain metabolism disorder.
Scientific research has proved that after satiety, there is a growth factor called "fibroblast" in the brain, which will increase by tens of thousands of times compared with that when it is not satiated, and this growth factor will make fat cells and capillary endothelial cells bigger, promote cerebral arteriosclerosis, cerebral cortex hypoxia, brain tissue atrophy, brain function degradation, and eventually lead to dementia and shorten people's life span.
Third, full eating damages cells and makes people premature aging.
When people breathe, 2% of the oxygen absorbed is catalyzed by oxidase to form reactive oxygen species (free radicals), which is extremely harmful to human body and can cause cell damage, arteriosclerosis, disease, aging and even death. The more energy the human body consumes, the more reactive oxygen species it produces, and the faster the degree of human aging. Eating less can reduce the production of reactive oxygen species and protect cells from it, thus delaying aging.
Fourth, long-term satiety will make people obese, causing arteriosclerosis, coronary heart disease, diabetes, cancer and other diseases.
In fact, there was a discussion in ancient China that dieting can prolong life.
In order to live longer, the ancients also created the theory of "keeping in good health through the valley", that is, dieting. The living standard now is much higher than that of the ancients. There are not only polished rice and white flour to eat, but also big fish and big meat to eat, especially middle-aged friends, who have a successful career. Some people have become unit leaders and enterprise cadres. Today they come to visit and inspect, and tomorrow they will send someone. They will eat a delicious meal, with red faces and big bellies. They seldom know that illness and short life are the reasons behind food and wine.
