This is very important to me. First of all, obesity can lead to various diseases. Secondly, in appearance, there are also bad impressions, such as looking for a job and a partner. If it belongs to normal obesity, it is ok. Of course, many people pursue thinness, and people who are too thin are not good for their health. Lack of nutrition can lead to endocrine disorders, infertility and so on. Boys will lead to growth.
