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 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%

Methods of reducing female students' body fat rate by expanding data

1, diet and oil control

When we eat more carbohydrates, such as exquisite cakes and snacks with high sugar and starch, the higher the blood sugar, the more insulin and the more fat stored in the body. Therefore, to reduce the body fat rate, we must first control the intake of fat in the diet.

2. Eat more high-protein food.

China people are mainly high in carbohydrates, in contrast, protein's intake is seriously insufficient. Protein is an important source of muscle tissue growth. You need a lot of protein if you want to make up the lost calories. It is recommended to take one gram per kilogram of body weight.

3. Aerobic exercise burns fat

Aerobic exercise has always been considered as the most effective way to lose weight. Aerobic exercise can mobilize the whole body muscles to participate in activities and consume a lot of fat during oxidation. It follows the scientific principle of tailoring. For example, the average person jogging for one minute consumes about 15 kilocalories. If he jogs for 30 minutes every day, he can lose one kilogram a week without changing his diet.
