Body mass index is a formula to measure the ratio of height to weight. Measure is the calculated body mass index, such as height 1.7m and weight 65kg, and its body mass index =65÷ 1.7_=22.49. The body mass index of Chinese adults is ≤ 18.4, 18.5-23.9 is normal, 24-27.9 is overweight, and ≥28 is obese.
There is also a simple formula for calculating height and weight: height (cm)-105 (male)/100 (female) = standard weight (kg), and it is normal for adults to fluctuate up and down this number 10%. For example, for men with a height of 170cm, the standard weight is 170- 105=65 kg, and the fluctuation of 10% is between 58.5kg-7 1.5kg. Above this standard, 10% is overweight, below this standard, 10% is thin. If it deviates from the normal range, it is recommended to see a doctor in time and intervene under the guidance of a doctor.
