Q: Is BMI a perfect measurement of health? A: BMI is a useful screening tool, but it doesn't account for muscle mass, bone density, or overall body composition. It's a great starting point, but we recommend consulting with a healthcare professional for a complete health assessment.

Q: What is a "Normal" BMI range? A: For most adults, a healthy BMI falls between 18.5 and 24.9. Our tool will automatically highlight your category once you run your calculation.
