Frequently asked questions
What is a healthy BMI range?
For most adults, the World Health Organization considers 18.5–24.9 to be a normal weight range, with under 18.5 classified as underweight and 25 and above as overweight or obese.
Is BMI accurate for everyone?
BMI is a screening tool based on height and weight only — it does not directly measure body fat and can be less accurate for athletes, older adults, and pregnant women.
