BMI FAQ
What do BMI values mean?
Under 18.5: underweight. 18.5-24.9: normal weight. 25-29.9: overweight. 30+: obese. BMI is a screening tool, not a diagnostic of body fatness or health.
Is BMI accurate for athletes?
BMI does not distinguish between muscle and fat. Very muscular individuals may have a high BMI despite low body fat. For athletes, body fat percentage is a better metric.
