Mass Index (BMI) FAQS What is Body Mass Index (BMI)? Body Mass
Index, or BMI, is a tool doctors use to identify potential
weight problems in adults, by comparing an individual's BMI to
the rest of the population. It is based only on your height and
weight, and so is an easy screening tool. Although it is an
indirect measurement, it has been shown to correlate closely in
most cases to more direct measurements of body fat. What Does My
Body Mass Index (BMI) Mean? Use your BMI to determine whether
you are at a healthy weight. The chart below gives the ranges
for underweight, normal weight, overweight and obese. If you
find yourself in any category besides "normal" you should
consult your doctor about ways to improve your health. Standard
BMI tables apply only to adults age 20 and older. The weight
categories do not depend on age or gender. ( See the BMI
