Formulas

BMI = weight(kg) / height(m)²

Underweight: <18.5. Normal: 18.5-24.9. Overweight: 25-29.9. Obese: ≥30.

Body Mass Index

BMI is a screening tool, not a diagnostic measure. It does not account for muscle mass, bone density, age, or sex differences. Athletes may have high BMI due to muscle, not fat.

Limitations

BMI does not distinguish between fat and lean mass. Waist circumference and body fat percentage are more accurate indicators of health risk.
