This is related to the distribution of human fat cells. Fat cells are like water sacs. If they drink more water, they will get fat, but if they drink less water, they will lose weight. Here we see two important factors of obesity, the number of fat cells (water sacs) and the number of fat-filled fat cells. The number of fat cells has a growth period in infants and adolescents, and then generally does not increase in terms of the number of fat cells. Therefore, the key in the later stage is how much water (fat) is poured into the water sac (fat cell). The release of fat cells under human skin is uneven. Under the same irrigation (fat filling), the more water sacs (fat cells), the more severe subcutaneous swelling (fat) will be. So our common obesity is that some people have big bellies and some people have big buttocks, which means that fat cells are unevenly released under the skin. Explain your problem, too
