Standard weight calculation formula

Formula one

[Height (cm)-100] × 0.9 = standard weight (kg)

Formula 2

Male: height (cm)- 105= standard weight (kg)

Female: Height (cm)- 100= standard weight (kg)

The above two calculation methods have basically been widely used. In addition, the Academy of Military Sciences recently introduced a method to calculate the ideal weight of China people:

The ideal weight of northerners = (height cm- 150)×0.6+50(kg)

The ideal weight of southerners = (height cm- 150)×0.6+48(kg)

This calculation method is more suitable for people in northern and southern China.

Because people's weight is related to many factors, there are differences between different people, and there will be certain changes at different times on the same day. In addition, the differences of geographical location (such as gravity), season, climate and self-condition also have certain influence on the weight, so it is difficult to reach the standard weight completely. In other words, it is difficult to express it with a constant value, but it should be a range of values, which we call normal value.

Generally within 10% of the standard weight. Beyond this range, it can be called abnormal weight.

The measured weight exceeds the standard weight, but the excess is less than 20%, which is called overweight; If the measured weight exceeds 20% of the standard weight and the fat percentage (F%) exceeds 30%, obesity can be diagnosed.

If the body weight exceeds the standard weight by 30%-50% and the F% exceeds 35%-45%, it is called moderate obesity; Those who exceed the standard weight by more than 50% and F% by more than 45% are called severe obesity.

Body mass index calculation method of body mass index

Body mass index (BMI) = weight (kg) ÷ height (m) 2

For example: 70kg ÷ (1.75x1.75) = 22.86.

Body mass index value

Body mass index, male, female

Too light: less than 20; 19 or less

Moderate: 20-25; 19-24

Overweight: 25-30; 24-29

Obesity: 30-35; 29-34

Very obese: over 35; Over 34 years old

Experts point out that the ideal body mass index is 22.
