About BMI

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

Limitations: BMI doesn't account for muscle mass, bone density, overall body composition, and racial/ethnic differences. Athletes with high muscle mass may have a high BMI but not have excess fat. It's always best to consult with a healthcare provider for a comprehensive health assessment.
