Standard weight is one of the important signs to reflect and measure a person's health. Being too fat and too thin is not good for your health, nor will it give you a sense of bodybuilding. A large number of statistical data of different body types show that the ideal and simple index reflecting normal weight can be expressed by the relationship between height and weight.
Extended data:
Standard weight = height (m) × height (m) × standard coefficient (female 20, male 22)
Standard weight plus or minus 10% is normal weight.
Standard weight plus or minus 10%~20% overweight or underweight.
A standard weight of plus or minus 20 is obesity or underweight.
