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%.

Extended data:
Normal reference range
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%.
Matters needing attention
Diet therapy and exercise therapy should be used at the same time to reduce calorie intake and increase calorie consumption through exercise to achieve the effect of losing weight. Dieting to lose weight without exercise will only reduce muscle but not fat, on the contrary, it will reduce basal metabolism and easily gain weight again.
