Frequently asked questions
Is BMI an accurate measure of health?+
It's a rough screening tool — it doesn't account for muscle mass, bone density, or where fat is distributed, so a muscular athlete can score "overweight" despite being lean.
What are the standard BMI categories?+
Under 18.5 is underweight, 18.5-24.9 is normal weight, 25-29.9 is overweight, and 30+ is obese, per the standard CDC/WHO thresholds.
