Many people have the idea that you can burn fat as much as you sweat in the gym. In contrast, you often don't feel sweating when swimming, and the weight loss effect will be greatly reduced. Sweating during exercise is often used as an indicator of whether you can lose weight.

Sun Jia, deputy director of the Department of Endocrinology and Metabolism, zhujiang hospital, Southern Medical University, said that this is one of the misunderstandings that many people are prone to fall into in weight loss exercise. However, in fact, even sweating does not mean that weight loss is effective. It takes more than 40 minutes for exercise to start burning fat.

Extended data movement needs to reach a certain speed and time to really play a role. Generally speaking, if the exercise lasts for more than 40 minutes, if the exercise time is insufficient and the fat is not mobilized, the purpose of losing weight will not be achieved.

"Glycosides are the easiest substances in the body to provide energy. When people exercise, they consume sugar first, and then they start to consume fat. When fat is mobilized to provide energy, it often takes more than 40 minutes of exercise time. "

As for the sweat volatilized during exercise, it can only show that the body is hot and needs to be cooled by sweating, which has nothing to do with the weight loss effect. Although you will lose weight after sweating, it is discharged water. As long as you replenish water, your weight will come back. Therefore, the effect of reducing fat cannot be simply measured by perspiration.

Sun Jia, deputy chief physician of zhujiang hospital Department of Endocrinology and Metabolism, Southern Medical University, believes that the effect of exercise should be judged by heart rate. "Under normal circumstances, the human heart rate is about 60- 100. After exercising for a certain degree of difficulty, intensity and time, the real effect of exercise can only be achieved if the heart rate exceeds 100. This time is often accompanied by sweating, so many people mistakenly think that sweating can lose weight. "
