First, regulate nervous and endocrine functions. The reason why normal people can maintain a relatively constant weight is mainly the result of the relative balance of synthesis and catabolism under the regulation of nervous system and endocrine system. In obese people, this regulatory function is disordered and metabolism is disordered. Anabolic metabolism is greater than catabolic metabolism, and excess sugar and fat are stored as fat. Strengthening exercise can improve the nervous and endocrine system, restore its normal regulation of metabolism, promote fat metabolism and reduce fat deposition.

Second, increase the consumption of fat and sugar in the body. After the fat in food enters the body, it is decomposed into free fatty acids and triglycerides, which enter the blood and are stored in fat cells. If you eat more fatty substances, adipose tissue will increase. In addition, too much sugar food will be converted into adipose tissue and stored in the body. When you increase the amount of exercise, muscle activity needs calories, so the utilization rate of free fatty acids and glucose in the blood increases, and fat cells can't be replenished, but they have to spend, so they shrink and shrink.
