FAQ

What is the BMI formula?
Metric: BMI = weight (kg) / height (m)². Imperial: BMI = 703 ÁEweight (lb) / height (in)².
Is BMI accurate for children?
No. For children and teens, BMI is age- and sex-specific and interpreted using growth percentile charts, not the adult cutoff values.
Why is my BMI high even though I exercise?
BMI does not distinguish between muscle and fat mass. Highly muscular individuals often have an "overweight" or "obese" BMI while having healthy or low body fat percentages.
