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.
Mild obesity: 20%-30% over standard weight;
Moderate obesity: 30%-50% over the standard weight;
Severe obesity: more than 50% of standard weight.
