BMI is a useful screening tool but has real limitations. It does not distinguish between muscle and fat, so muscular athletes often show elevated BMI despite low body fat. It also does not account for where fat is stored. Waist-to-height ratio and body fat percentage are more precise measures. Use BMI as a starting point, not a definitive health verdict.
