Body mass index (BMI) is a figure obtained by dividing the weight in kilograms by the square of the height in meters. It is a widely used international standard to measure the degree of obesity and health. Mainly used for statistical purposes, when we need to compare and analyze the impact of a person's weight on the health of people of different heights, the body mass index value is a neutral and reliable indicator.

The role of body mass index has also changed slowly, from medical to mass slimming index.
