Frequently Asked Questions
What is BMI?
BMI (Body Mass Index) is a measure of body fat based on height and weight. It applies to adult men and women and is a screening tool, not a diagnostic.
What are the BMI categories?
Underweight: below 18.5, Normal weight: 18.5–24.9, Overweight: 25–29.9, Obese: 30 and above.
Is BMI always accurate?
BMI is a useful screening tool but does not measure body fat directly. Athletes with high muscle mass may have a high BMI but not be overweight.
