Questions fréquentes

What is the BMI formula?

Metric: BMI = weight (kg) ÷ height (m)². Imperial: BMI = (weight in lb ÷ height in inches²) × 703.

What are the BMI ranges?

WHO adult ranges: under 18.5 = underweight, 18.5–24.9 = healthy, 25–29.9 = overweight, 30–34.9 = obesity I, 35–39.9 = obesity II, 40+ = obesity III.

Is BMI accurate for everyone?

BMI is a screening tool, not a diagnosis. It doesn't distinguish muscle from fat, so athletes and very muscular people may be classified as overweight even when they are lean. Talk to a healthcare provider for a full assessment.
