Is high or low body fat rate good for health?

Too high or too low is not good. It goes without saying that high body fat rate is obesity. Everyone knows that obesity can lead to many diseases. The body fat rate is too low, the ability to keep out cold is poor, and it is easy to catch a cold. Moreover, fat also has the function of protecting muscles, and it is easier to get injured if you exercise too low. Bodybuilders in the muscle-building period all maintain a certain body fat, which also has a certain role in protecting muscles for heavy-load training. Personally, I think the average man can keep it at 10~ 18%, and the woman can keep it at 20~27%, so the figure is actually very beautiful ~
