What Is BMI?
Body Mass Index, commonly called BMI, is a numerical measurement calculated using a person's weight and height. It is commonly used as a general screening measurement to classify weight relative to height.
BMI does not directly measure body fat and does not account for every factor that can affect a person's health. Therefore, it should be treated as a general reference rather than a complete assessment of health.
