1, some people often exercise, but they are getting fatter and fatter, and losing weight has become a bubble. This is because they don't exercise reasonably when they exercise.

2, exercise can improve the body's basal metabolic rate and consume calories, so it helps to lose weight. The researchers asked 72 women to run for 30 minutes and measured the concentration of leptin, the product of obesity gene, in the blood before and after exercise. The results showed that 86% of the subjects' weight loss protein increased significantly. The results show that high-intensity exercise basically does not consume fat, especially during anaerobic exercise, the metabolite produced by anaerobic glycolysis of muscle glycogen is lactic acid, which is mostly decomposed into carbon dioxide and water in the liver under aerobic conditions.

3. The other part re-synthesizes hepatic glycogen, but there is also a small amount of lactic acid to synthesize fat through metabolism. This is why high-intensity exercise can not only lose weight, but also sometimes increase the accumulation of fat in the body. Therefore, sports medicine experts suggest that people who want to lose weight generally exercise for half an hour to an hour, and their heart rate reaches about 130- 175 per minute, which can be regarded as moderate exercise and can increase the concentration of protein for losing weight.
