What's Your Body Mass Index (BMI)?
BMI is a way to figure out your approximate level of body fat in an easy, inexpensive way. It's a number based on your weight and height that can help you tell if you are at a healthy weight for your height. In general, the higher the number, the more body fat a person has.
