Quick FAQ
Is BMI accurate?
It’s a useful screening tool, but not a full picture. Combine it with waist measurement, fitness level, and clinical markers.
Can athletes use BMI?
BMI often overestimates body fat in muscular people. Consider body-fat or DEXA scans.
Does age matter?
Yes. With aging, body composition changes. BMI cutoffs are the same, but interpretation should consider overall health.
What about children?
Use BMI-for-age percentiles (pediatric growth charts), not adult categories.
