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%.

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:

If you want to know the amount of body fat, you need a special instrument to measure it. Ordinary body composition analyzer can quickly measure the percentage of body fat. Body fat percentage is a "one-vote veto system" for body shape, that is, whether the body mass index is normal or not, as long as the body fat percentage is judged as obesity or obesity.

In addition to the tall equipment such as the body composition meter, we also have a small helper for home measurement, that is, the soft ruler. By measuring waist circumference and hip circumference, we can also know whether it is necessary to reduce fat.

Waist measurement: wrap the soft ruler horizontally around the navel 1 cm.

Hip circumference measurement: surround the soft ruler horizontally along the most prominent part of the hip.

Pay attention to keep it flat, and there is no obvious depression in the skin. Calculate the waist-hip ratio. Waist-hip ratio = waist circumference/hip circumference
