China standard of obesity: Chinese experts believe that although China people belong to Asian race, the upper limit of the normal range of body mass index should be lower than the Asian standard. Some experts suggested that the best value of China people's body mass index should be 20-22, with a BMI greater than 22.6 as overweight and a BMI greater than 30 as obesity.
Ideal weight (kg) = (18.5 ~ 23.9) × the square of height (unit m) According to the standards set by the World Health Organization, Asians are overweight if their BMI (Body Mass Index) is higher than 22.9. Asians and Europeans and Americans belong to different races, and WHO standards are not very suitable for China people.

BMI calculation method
Male: (height cm-80) × 70% = standard weight.
Female: (height cm-70) × 60% = standard weight.
Standard weight plus or minus10 is normal weight, standard weight plus or minus10 ~ 20% is overweight or underweight, and above standard weight plus or minus 20% is obesity or underweight. Overweight% = [(actual weight-ideal weight)/(ideal weight) ]× 100%
Because people's weight is related to many factors, there are differences between different human bodies, and it will also change at different times of the day. In addition, the geographical location (such as gravity), season, climate and one's own situation also have a certain impact on weight, which should be a numerical range. We call this numerical range normal, generally within the range of standard weight+10%.
