What BMI Tells You

BMI is a useful screening tool that correlates with health risks. However, it doesn't directly measure body fat or account for muscle mass, bone density, or overall body composition.

💡 Note

Athletes with high muscle mass may have a high BMI but low body fat. Consult a healthcare provider for a complete health assessment.
