Understanding BMI's Limitations

BMI is a screening tool, not a diagnostic one. It does not account for body composition (muscle vs. fat), age, or sex. An athlete may have a high BMI due to muscle mass, not excess fat. Always consult a healthcare professional.

What is BMI?

Body Mass Index is a measure that uses your height and weight to work out if your weight is healthy. The calculation divides an adult's weight in kilograms by their height in metres squared.
