Frequently Asked Questions
What is BMI?
Body Mass Index is a measure of body fat based on height and weight. It's a screening tool, not a diagnostic measure.
What's a healthy BMI?
A BMI between 18.5 and 24.9 is considered normal weight. However, BMI doesn't account for muscle mass or body composition.
