But we need to know one thing: "Fat is necessary for human body composition, too much or too little will affect health." For men, about 3-4% of body fat is essential fat.
For women, 10- 12% fat is essential fat, and lower than this standard will affect health. Men's body fat is higher than 25%, and women's body fat is higher than 35%, which is not only ugly but also affects health.
Extended data
Formula for calculating body fat rate of adult women:
Parameter a= waist circumference (cm) ×0.74
Parameter b= weight (kg) ×0.082+34.89.
Body fat weight (kg) = a-b
Body fat rate = (total body fat weight/body weight) × 100%
Formula for calculating body fat rate of adult males:
Parameter a= waist circumference (cm) ×0.74
Parameter b= weight (kg) ×0.082+44.74.
Body fat weight (kg) = a-b
Body fat percentage = (total body fat weight/body weight) × 100%.
The normal range of adult body fat rate is 20% ~ 25% for women and 15% ~ 18% for men. If the body fat rate is too high and the weight exceeds 20% of the normal value, it can be regarded as obesity. The body fat rate of athletes can be determined according to sports events. The average of male athletes is 7% ~ 15%, and the average of female athletes is 12%-25%.
