What is the body mass index?
Body mass index is an important international standard to measure the degree of obesity. Body mass index is obtained by calculating the value of human body weight and height, which can effectively judge a person's health and nutritional status.
Body mass index < 18.5 thin.
Body mass index = 18.5~23.9 normal.
Body mass index =24~26.9 Overweight.
Body Mass Index & gt27 Obesity
Calculation formula of body mass index
Body mass index = weight (kg)/height? (meter)
For example, the body mass index of a person weighing 60kg and height 160cm is
60/ 1.602=23.4, and the body mass index value is within the normal range.
What is body fat percentage?
Body fat percentage refers to the percentage of body fat mass to body weight.

40~59 years old, 35~39%
Over 60 years old, 37~4 1%

18-39 years old 40~45%
40~59 years old 4 1~45%
42~45% over 60 years old
Weight 46kg, body fat rate 15%.
Weight 46 kg, body fat rate 24%
Even if the weight is the same, the difference in body fat will affect the figure.
Calculation method of body fat percentage
1.2xBMI+0.23x Age -5.4- 10.8x Gender (male 1, female 0)= body fat rate.
The normal range of male body fat rate is 10%~20%, and the normal range of female body fat rate is 18%~28%.
Only when the body mass index and body fat rate exceed the standard can it be considered as true obesity, and if the body mass index is in the normal range and the body fat rate exceeds the standard, it is invisible obesity.
Measurement method of waist-hip ratio
Waist circumference/hip circumference = waist-hip ratio
Measurement position of waist circumference and hip circumference
least waist circumference
Maximum hip circumference
The waist-hip ratio of women should be below 0.85.
Male waist-hip ratio should be below 1.0.
