How It Works
BMI=weight(kg)/height(m)². Adult cutoffs: underweight <18.5, healthy 18.5–<25, overweight 25–<30, obesity ≥30.
Category is determined from unrounded BMI. BMI alone cannot diagnose an eating disorder.
Scope and Limitations
- Adult screening estimate only; not for children, pregnancy or individualized diagnosis. BMI does not distinguish muscle from fat.
