Body mass index, or BMI, is a commonly used international standard to measure obesity and health.
The obesity standard of Asians should be that the body mass index is normal at 18.5-22.9, the body mass index greater than 23 is overweight, and the body mass index greater than 30 is obese.
Extended data
Body mass index measurement became popular in 1970, but it may not be suitable for everyone, such as some boxers and rugby players, whose muscle ratio is much higher than fat.
Athletes' muscle density is higher than fat, so they are heavier than fat. Therefore, their body mass index may exceed the standard, but in fact they are healthy. Of course, this kind of people only account for a very small number of the population, about 1%.
With the increase of age, the muscle proportion of athletes will decrease, and there may be a lot of visceral fat, especially for some smokers.
In addition, the body mass index is not suitable for pregnant women.
The distribution position of fat in human body is very important, which cannot be measured by body mass index. Therefore, it is best to combine body mass index and other readings, such as blood pressure, cholesterol and family history, to judge a person's risk of diabetes or heart disease.
