What is BMI?

Body mass index or BMI, is used to determine whether you are in an ideal weight range for your height.

It gives you an idea of whether you're "underweight", a "healthy weight", "overweight", or "obese" for your height. BMI is one type of tool to help health professionals assess the risk for chronic disease. 

BMI is a useful measurement for most people over 20 years. It is an estimate and should be considered as a rough guide only as it does not take into account age, gender, ethnicity or body composition.
