Body mass index = weight (kg) divided by the square kg/m2 of height (m). Generally speaking, normal body mass index is between 18 and 25, overweight body mass index is between 25 and 30, and obese body mass index is above 30. The criteria are as follows:
1) Normal weight: body mass index =18-25;
2) Overweight: body mass index = 25-30;
3) Mild obesity: body mass index >; 30;
4) Moderate obesity: body mass index >; 35;
5) Severe obesity: body mass index >; 40。
The proportion of height and weight is also related to age, and the proportion of different ages is different. So you can't lose weight blindly, and at the same time you can't let your weight rise uncontrollably. Being too thin and overweight is bad for our health.
Most models and stars on TV are thin, so those women who love watching TV and have normal weight should not be dissatisfied with their bodies. Normal weight is beauty, health is beauty, don't pursue that kind of deformed beauty.

Calculation method of normal person's weight
1) The standard weight of adults: (height cm- 100 cm) × 90% = standard weight (kg), which is a commonly used weight calculation formula in the world, and the calculation of body proportion (more suitable for orientals), except those who have practiced fitness. When the weight exceeds 10% of the standard weight, it is said to be overweight; More than 20% of the standard weight is called mild obesity. When it exceeds 30% of the standard weight, it is called moderate obesity. When it exceeds 50%, it is called severe obesity.
2) Standard weight of children: (age ×2)+8= standard weight (kg). When the weight exceeds 10% of the standard weight, it is called overweight. More than 20% of the standard weight is called mild obesity. When it exceeds 30% of the standard weight, it is called moderate obesity. When it exceeds 50%, it is called severe obesity.
