What is BMI?

Body Mass Index (BMI) is a simple measure using height and weight to estimate body fat. It's calculated as weight (kg) divided by height (m) squared. While BMI doesn't measure body fat directly, it's a useful screening tool used by healthcare professionals worldwide.

BMI Limitations

BMI doesn't distinguish between muscle and fat mass. Athletes may have high BMI despite being healthy. Age, sex, and ethnicity also affect the interpretation. For a complete assessment, consult a healthcare professional.
