Body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women.

1. Enter your weight and height.
2. Select ‘Compute BMI’ and your BMI will appear.

Although BMI can be used for most men and women, it does have some limitations:

• It may overestimate body fat in athletes and others who have a muscular build.
• It may underestimate body fat in older persons and others who have lost muscle.
