Eating too much and losing weight may be because what you eat is not fully absorbed by your stomach. In this case, some metabolic diseases must be ruled out first. For example, hyperthyroidism, some gastrointestinal digestive dysfunction, some lactose deficiency, exclude some other tumors, and treat them according to specific causes.

In addition, some people are in good health. Generally speaking, being thin has family genetic factors. All aspects of the body function normally, and it doesn't matter if you are thin. You can have reasonable nutrition, reasonable diet and reasonable life.

If there is really weight loss caused by disease, then specific treatment is needed. If you want to gain weight, you should pay attention to the nutrition collocation, the law of daily life, the combination of work and rest, and the regular and appropriate physical exercise, which can strengthen your physique, improve your resistance and improve the absorption capacity of the gastrointestinal tract.

Good figure is also directly related to diet, but excessive dieting and weight loss will seriously affect health. To control appetite, we should also master good methods, such as drinking a little less at a time, drinking two glasses of water or a bowl of soup before eating, buying small packages of food, eating more crude fiber foods that increase satiety, such as beans and konjac, using shallow dishes and transparent tableware, and consciously helping others turn over the table and pick up vegetables when eating, all of which are good ways to avoid overeating.
