In addition, back to the third floor, exercise is of course essential, but let me give you an example. This is an example told by a professor at Beijing Sun Sheng Tang: There was a boy with hypothyroidism who was very fat. At first, the doctor didn't find that he had hypothyroidism, so he was asked to exercise as much as possible every day. As a result, after a while, the young man couldn't lose weight, but he couldn't walk fast. Results Follow-up showed hypothyroidism. Later, tonic medicine was prescribed, but the effect was reduced. This is virtual, fat people are more virtual, and too much exercise is more virtual. This is a fact. Therefore, it is necessary to distinguish the types of obesity and treat them symptomatically.
