Frequently Asked Questions

What is a healthy BMI range?

A BMI between 18.5 and 24.9 is considered normal weight. Below 18.5 is underweight, 25-29.9 is overweight, and 30 or above is obese.

Is BMI accurate for everyone?

BMI is a useful screening tool but doesn't account for muscle mass, bone density, or body composition. Athletes may have a high BMI due to muscle mass despite being healthy.
