Body Mass Index


Body Mass Index (BMI) is a good way to assess your body weight relative to height. This method is an indirect measure of body composition because it correlates highly with body fat in most people. Having a BMI above 25 can indicate a high risk of developing cardiovascular disease, diabetes, strokes, certain cancers, and osteoarthritis.
