What Does Body Mass Index Mean?

By

Definition: Body Mass Index (BMI) is a number calculated from a person’s weight and height information. BMI equals a person’s weight in kilograms divided by height in meters squared or BMI=kg/m2. The resulting number provides a dependable estimate of body fat levels for most people and is used to identify weight categories that could result in health problems. Body mass index is the preferred method of measurement for many physicians and researchers who study obesity.
