Don't skip the staple food in order to lose weight. I don't know if anyone knows that in Japan, a person who successfully lost weight without eating staple food suddenly died of heart failure in a restaurant. China's vice minister of health once said that eating less will only cause immune system problems and easily rebound. According to American nutritionists and doctors, a low-carbohydrate diet can indeed lose weight in a short time, but this advantage can only play a role in a short time, and obesity will continue for a long time.
Doing strenuous exercise once a week is good for your health. If you have this idea, you'd better get it out of your mind as soon as possible. If you are a quiet person and don't exercise often, suddenly one day you do a lot of exercise and spend a lot of energy, which will not bring you benefits, but will also hurt you. Only fat people need to exercise. It doesn't matter if you're not fat. Obesity does have an impact on health, but it is not a measure of your health, if you are not fat.
It can't prove that you are healthy, and some people with just right weight have unbalanced cholesterol, glycerol and blood sugar. If we want to be healthy, we should learn to analyze our behavior reasonably, not subjectively, because some things are either good or not, just like people's eyes sometimes blind themselves. Learning to analyze problems from a scientific perspective is also a great development.
