Sports need to reach a certain speed and time to really play a role. Exercise should last 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.

Precautions for exercise to lose weight:
1, learn to protect yourself during exercise.
Joints are "victims" who are easily injured in sports. Sun Jia reminded that patients who lose weight are often overweight and their joints are worn out during exercise. Choosing to climb mountains or insisting on climbing stairs to lose weight is not worth the loss. It is suggested to lose weight by walking on the flat ground and walking at a brisk pace, and then choose other exercise methods after the weight tends to be normal.
2, the weight should be reduced step by step.
"Losing weight is not an overnight thing. It may not be fat but water that is easy to lose. For ordinary women, it is more appropriate to lose 2-4 kg a month. If you are a person with a large weight base, it is more reasonable to reduce 10- 15 kg a month. Both diet and exercise need to be reduced step by step. "
3, fat is not a "bad thing", don't resist too much.
Women, especially women of childbearing age, should pay attention to fat intake. Because fat provides essential hormones for the body, "zero fat" will affect hormone metabolism in the body and ovulation may occur. Women who have fertility requirements can control their weight within a reasonable range without excessively pursuing "thinness".
