About BMI
Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women.
The BMI formula is: weight (kg) / [height (m)]². It provides a reliable indicator of body fatness for most people.
Note: BMI is a screening tool and not a diagnostic measure. Athletes and very muscular individuals may have a high BMI due to muscle mass, not excess fat.
