What is the body mass index?

Body mass index (BMI) is the simplest and quickest way to measure whether your weight is up to standard. As long as you know your height and weight, you can judge whether your weight is normal or not at any time, and you can also know whether you have the "potential" of obesity. Body mass index (BMI) is also a calculation method recommended by medical circles to control ideal weight, which can be used as reference data before body shaping. The calculation of body mass index is not complicated, and a simple formula can tell whether your weight is normal or not.

Body mass index = weight (kg)/height (m) squared.
