Obesity has an impact on human health. In any case, everyone should lose weight, especially some girls are very strict about their body management and can't accept the fact that they are fat, so they will lose weight. Many people around us lose weight through diet and then exercise. Some people seldom eat staple food, or don't eat staple food at all. Coupled with high-load exercise, it really works. However, if this happens for a long time, I think my health will be affected. After all, if I don't eat staple food, it will affect the metabolism of nutrients in my body and cause malnutrition. It is also related to people's physique. Some people get fat easily after drinking cold water, which is hereditary. Even if they eat very little, they will still get fat. Therefore, we can only change this physique through exercise, not dieting to lose weight. In fact, exercise is the best way to lose weight, and it is also a way of keeping in good health. Now most people like to go to the gym to lose weight, and there is a better sports atmosphere in the gym. There is no reason not to lose weight when you see others in such good health and working so hard.
