Frequently Asked Questions
What is a healthy BMI?
A BMI between 18.5 and 24.9 is considered healthy. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.
Is BMI accurate?
BMI is a useful screening tool but doesn't account for muscle mass, bone density, or fat distribution. Athletes may have high BMI despite being healthy.
