The simplest thing to think about is that fat is generally oil, so how can oil turn into water and be excreted, especially since sweat is basically 99% water. Let me give you an example. In hot summer, we will sweat when sitting in the yard. So, have we lost fat? Excluding normal metabolism, our fat has basically not changed. Sweating is because the function of the human body is to regulate the body's constant temperature, expand pores and dissipate heat. Some people say that you will lose weight after sweating. That's for sure. With so much water in your body, you will definitely lose weight. There is a kind of sportswear specially worn by boxers, which can quickly expel water from the body before the game and meet the weight requirements.
Another example can have some extremes. But we can also find that sweating and reducing fat are two different things. We can see from textbooks that people in poor areas in Africa are basically very thin. How can they have the strength to exercise and sweat when they have problems eating? This just shows that sweating and fat loss are not necessarily related.
The simplest way to lose fat is energy intake and energy consumption. Of course, if you sweat a lot, it proves that you are engaged in high-intensity work, which will inevitably increase energy consumption, that is, burning fat. Of course, simple sweating has nothing to do with reducing fat.
Don't trust people who say that you will burn fat after running for 30 minutes. As long as you move, you will consume energy. If you don't replenish energy, you will burn fat. After all, your brain will tell your body that I don't want to die. Burning fat provides energy.
