Frequently asked questions
What is a healthy BMI range?
For most adults, a BMI between 18.5 and 24.9 is classified as the normal-weight range by the WHO. Ranges differ slightly for some ethnic groups and do not apply to children or pregnant women.
Is BMI accurate for athletes?
Not always. BMI cannot distinguish muscle from fat, so very muscular people can be classified as overweight while carrying little body fat. Use it as a screening number, together with waist circumference and body-composition measurements.
