There is a certain proportion between a person's height and weight. It is generally believed that the standard weight (kg) is the height (cm) minus 105, overweight is 10%, and overweight is 20% (some people think overweight is 30%). Others calculate the standard weight by subtracting 100 from those below 150cm,1-165cm and 166cm. How can we calculate a person's fatness more accurately? The simple method is to use the following formula to calculate:

Male: standard weight (kg) = height (cm)-100- (height-150)÷4 female: standard weight (kg) = height (cm)-100- (height-/kloc-0

Obesity = (actual weight-standard weight calculated by height) ÷ standard weight calculated by height × 100% For example, if a middle-aged woman is 160 cm in height and weighs 75 kg, then her standard weight is160-105 = 55. According to another formula,160-100-(160-150) ÷ 2 = 55 (kg).

Obesity = (75-55) ÷ 55×100% = 36.1%According to the above regulations, anyone who exceeds 30-50% of the standard weight is severely obese, so this person is moderately obese.
