Frequently Asked Questions

What is a healthy BMI range?

A BMI of 18.5–24.9 is considered healthy. Under 18.5 is underweight, 25–29.9 is overweight, and 30+ is obese.

Is BMI an accurate measure of health?

BMI is a screening tool, not a diagnostic measure. It does not account for muscle mass, bone density, or fat distribution.
