There are five forms of human energy consumption: basic metabolism, exercise energy consumption, breathing, defecation and perspiration. Sweating is also a form of energy consumption. As long as you consume energy, you can lose weight. It's just a matter of speed.
In fact, the more you sweat, the easier it is to cause a rebound. Blindly increasing the amount of exercise will make the body lose too much sweat, destroy the internal environment, and the physical strength will drop obviously, but the loss of muscle tissue and tissue fluid will lead to the decline of physical strength, and it will be impossible to continue the original amount of exercise, and soon the weight will rise again and it will look fatter than before.
So winter exercise is actually just an arch after summer exercise, which is very helpful to lose weight.
