BMI Limitations

BMI doesn't distinguish between muscle and fat. Athletes may have high BMI due to muscle. It also doesn't account for age, gender, or body composition. Consult a healthcare provider for complete assessment.

Frequently Asked Questions

BMI may overestimate body fat in athletes with high muscle mass. Other measures like body fat percentage or waist circumference provide better insights.

Generally 18.5–24.9 is considered healthy, but optimal BMI varies by age, ethnicity, and individual health factors.
