Generally, after 20 years old, the number of fat cells is basically fixed. After that, fat can only be eliminated by liposuction and other methods. For adults at this stage, when normal food is digested by the digestive tract, it will not affect the number of fat cells, only by dieting and exercising more, thus reducing the volume of fat cells.
In other words, when overweight or losing weight, fat cells may shrink or increase, but the number of fat cells will not change. However, this does not mean that the number of fat cells will remain unchanged for life. The number of adipocytes in children and adolescents is increasing, while the number of adipocytes in adults has stopped growing.
Extended data:
Gu Zhongyi, a nutritionist at Friendship Hospital affiliated to Capital Medical University, said that obesity is mainly due to the increase in the number or volume of fat cells. The volume can be increased at any time, and the increase is mainly concentrated in the late fetus, infancy and adolescence, so the balance between energy intake and consumption should be strictly controlled in these stages to avoid obesity.

Experts emphasize that the principle of fat skimmer and other devices is to reduce the size and gap of fat cells, so it feels like losing weight, but it does not lose the total amount of fat. In addition, fat shedding is a passive exercise, and fat is not burned throughout.
This kind of passive motion can't consume energy. Therefore, the skimmer has little effect on weight loss, and can only massage at most. If the body is subjected to high-frequency and severe external vibration for a long time, it may also cause many diseases such as lumbar muscle injury.
