Body Mass Index (BMI)

Body Mass Index (BMI) compares height with weight. This can be a useful tool in establishing if someone has a healthy weight or could benefit from a weight management program. It is important to note that BMI is an estimate and not a true reflection of body composition. In certain cases care must be taken when interpreting BMI, for example some athletes with large muscle mass maybe classified overweight or even obese, despite having low body fat.
