At present, the commonly used methods to lose weight are: 1. Exercise to lose weight; Second, liposuction to lose weight; Third, drugs to lose weight; Fourth, acupuncture weight loss, as well as massage and other methods to lose weight. These methods are mainly carried out from the above three aspects except smoking to lose weight. For example, controlling diet, suppressing appetite with drugs, acupuncture or other methods to reduce the energy intake of the body; Running to lose weight increases the body's energy consumption. Acupuncture and some drugs can not only reduce energy intake, but also promote fat decomposition.

3. How to make the method of losing weight scientific and reasonable?

(1) Exercise to lose weight: It is the most commonly used method to lose weight, and it relies on physical activities to consume energy substances to achieve the purpose of losing weight. Exercise to lose weight requires not only a certain amount of exercise, but also long-term persistence and proper dieting. Practice has proved that only by exercising for more than 30-45 minutes can the body's fat be mobilized to supply energy with glycogen. With the development of exercise time, the energy provided by fat reaches 85% of the total consumption. It can be seen that exercise shorter than 30-45 minutes has no obvious fat consumption regardless of the intensity. Exercise can improve the body's basal metabolic rate, cause hunger, increase appetite, and lead to an increase in diet, intake of more calories and increase the accumulation of body fat.

Therefore, it is necessary to match the diet. Exercise improves the body's basic metabolism. If you suddenly stop exercising, your body will consume more energy than it consumes, and the excess energy will be stored in the form of fat, which will lead to weight gain.

(2) liposuction to lose weight: it is to remove excess fat in the human body through surgery. The advantages of this method are quick effect and obvious effect; Its characteristics are: high risk, great pain, strict surgical contraindications, and no solution to the problem of weight gain.

(3) Drug weight loss: a method to lose weight by suppressing appetite or increasing excretion. The advantage of drug weight loss is that it is convenient to take medicine and does not take much time; Moreover, its shortcomings are also obvious: it causes imbalance of water and electrolyte, metabolic disorder, low resistance and serious weight rebound after losing weight. Especially the use of drugs to promote the decomposition of fat, in order to improve the body's

Basal metabolic rate is dominant, such as thyroxine. The harm of these drugs to human body is serious. It not only promotes lipolysis, but also causes metabolic disorder of glucose and protein. Therefore, the use of such drugs should be strictly prohibited in the process of losing weight.
