Many people feel envious, seeing how others eat is not fat, and then looking at themselves, drinking cold water will make them fat. However, this envy should be as little as possible. From the perspective of traditional Chinese medicine, the symptoms of this kind of people belong to spleen-stomach disharmony, accompanied by various deficiency diseases. That is to say, the function of the spleen is to promote digestion and absorption, but it can't work. When it stops working, it will lead to more things in the stomach being excreted directly through the intestine, and the body can absorb very few nutrients and other beneficial components. Because such people are thin, but they can eat well at ordinary times, everyone will be surprised why they are not fat. In fact, they like to eat and are willing to eat because they lack nutrition in their bodies and need to keep eating to maintain normal demand. Once they don't eat, their bodies will soon get sick.
From the perspective of western medicine, it is basically indigestion caused by insufficient active fungi and abnormal gastrointestinal peristalsis. That is, the stomach has no motivation, similar to what people often say in TV advertisements to buy stomach medicine. One is to increase the peristalsis of the stomach and promote food digestion, and the other is to increase the probability that food nutrients are absorbed by rapid peristalsis, which can not only meet the needs of the body, but also promote defecation. But most thin people should have no difficulty in defecation, because their physique is poor and their ability to accept food is far less than that of normal people. This is especially true for highly irritating foods. Although such people often think that eating some irritating foods will make their appetite better, it will not be beneficial to the body and spleen and stomach in essence, and it will increase the burden.
