Body mass index (BMI) is an index used to judge healthy weight at present. The calculation method is to divide the weight (kg) by the square of the height (m).

The body mass index of healthy adults (18-64 years old) in China should be between 18.5-23.9. For most people, the increase of body mass index generally reflects the increase of body fat weight, but for athletes and people with a large proportion of body muscles, this range of body mass index is not applicable.

Body mass index standard:

Obesity: Body Mass Index = & gt28;

Overweight: 24

Normal weight: 18.5

Underweight: Body Mass Index

If it is an adult, its height 170cm, weight 60kg and body mass index 20.8 belong to the normal weight range.
