Body mass index (BMI) is a measure of body fat based on height and weight. BMI is an estimate of body fat and a good estimate of your risk for diseases that can occur with obesity. The higher your BMI, the higher your risk for certain diseases such as heart disease, hypertension, diabetes,, and certain respiratory disorders. The National Institutes of Health (NIH) now defines normal weight, overweight, and obesity according to BMI rather than the traditional height/weight charts.
