More Information
Body mass index (BMI) is a tool used to estimate body fat. For most people, BMI is reasonably accurate, but it is not an exact measurement. However, BMI may underestimate body fat for older people or people who have little muscle mass or overestimate body fat for athletes and people who are very muscular. Talk to your doctor if you have questions or concerns about your weight or about how to gain or lose weight safely.
