Eat less greasy food, do more aerobic exercise, try to eat less foods with high fat content, and eat more beans or milk with high protein content. Eat less food with high sugar content, eat regularly, chew slowly and be 70% full. Body fat rate refers to the percentage of body fat content to body weight. The normal body fat rate of women is 20% to 30%, and that of men is 15% to 18%. Fast-paced life makes work more and more busy, and exercise time is greatly reduced, so fat will accumulate in the body and the body fat rate will increase.
