There are three main types of weight loss that are popular in the world. The first category is lifestyle change. In fact, weight loss is mainly diet control plus some exercise and activities. The second category, some drugs or some therapies, such as Chinese medicine diet pills, acupuncture, catgut embedding and massage. The third category is the operation method. Judging from the effect of treatment, in fact, we can know that diet control is the simplest and most economical method that everyone can do, but it is difficult to operate because of the need to strictly control diet and proper exercise. In addition, it needs a long-term and persistent process. If you don't eat or exercise for a short time, you may lose weight, and once you relax, you may bounce back soon. Therefore, this method needs firm confidence and strong willpower to persist for a long time, and finally it can turn decay into magic. In fact, the proportion of people who can lose weight in this way is relatively low. At present, diet pills and some physical therapy methods may also achieve the initial weight loss effect. But in fact, the weight loss effect of drugs is not ideal, and there are still some complications. The same is true of physical therapy, which may achieve the effect of losing weight in a short time, and may also have the problem of rebound. At present, the reliable way to lose weight is surgery, by reducing the size of the stomach, removing a part or rebuilding the gastrointestinal tract. This can quickly lose weight, which is a more reliable method. Not all patients are suitable for surgery. For some diabetic patients with relatively large weight, it may be better to lose weight through surgery, but it is not suitable for patients with relatively small weight to have surgery.
