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.
