Note: BMI is a screening tool, not a direct measure of body fat. It may not accurately reflect health for athletes (higher muscle mass), elderly (loss of muscle mass), children, pregnant women, or certain ethnic groups. If your BMI is outside the healthy range, consult a healthcare provider for a comprehensive assessment.
