What is BMI?

Body Mass Index (BMI) is a measure of body fat based on height and weight. It's calculated by dividing weight in kilograms by height in meters squared.

Limitations: BMI doesn't distinguish between muscle and fat. Athletes may have high BMI with low body fat. It's a screening tool, not a diagnostic.
