What is BMI?
BMI is the common acronym given to Body Mass Index. Your BMI is a number calculated from your weight and height and will roughly correlate the percentage of your total weight that comes from fat, as opposed to muscle, bone or body organs. The higher your BMI, the higher the percentage of fat in your body. If your BMI is under 20, you may be underweight. If your BMI is between 20 and 25, you are probably at a good healthy weight for your height. A BMI over 25 is considered overweight, and over 35 is considered obese.

How Is BMI Used?
BMI is not a diagnostic tool. For example, a person may have a high BMI. However, to determine if excess weight is a health risk, a healthcare provider would need to perform further assessments. These assessments might include skinfold thickness measurements, evaluations of diet, physical activity, family history, and other appropriate health screenings.
