Adults:

Male (height -80) × 0.7 (kg)

Female (height -70) × 0.6 (kg)

Children: Age × 2+8 (kg)

Standard weight+10% belongs to the normal range; 20% overweight is mild obesity; 50% overweight belongs to severe obesity.

In addition to the above calculation criteria, we should also consider whether the bones are strong, whether the muscles are developed, and whether the fat is fat and distributed.

Method 2: Accurate calculation method

"Northerners" in the north of the Yangtze River Valley: ideal weight (kg) = height (cm)- 150× 0.6+50.

"Southerners" in the south of the Yangtze River Basin: ideal weight (kg) = height (cm)- 150× 0.6+48.

30 ~ 50% of the weight > standard weight is moderately obese.

Weight > 50% of standard weight is severe obesity.

Method 3: Body Mass Index (BMI) calculation method.

The formula for calculating the body mass index published by the World Health Organization (WHO) is:

BMl= = Weight (kg)/Height (m) 2

BML < 18.5 is emaciation; BMl is normal between 18.5 ~ 24.9; BMl≥25 is overweight; The BMl between 25 and 29.9 is 1 obesity; Bml > 30 ~ 34.9 is grade 2 obesity; Bml > 35 ~ 39.9 is grade 3 obesity; Bml > 40 is grade 4 obesity.

Method 4: calculation method of waist-hip ratio

Waist circumference (WC) and waist-hip ratio (WHR) are also indicators to detect obesity. If the waist circumference of men is greater than 85 cm and that of women is greater than 80 cm, or the ratio of waist circumference to hip circumference is greater than 9.0 for men and 8.5 for women, abdominal obesity can be considered.
