BMI, or Body Mass Index, is an estimate of the amount of tissue mass (muscle, fat and bone) an adult man or woman has. This information is used to categorize that person as underweight, normal weight, overweight or obese. It is important to know that BMI cannot distinguish between excess fat and muscle, so the BMI of a very muscular person may be classified as obese when he or she is not.
For further consultation about BMI, please see your primary care provider.
