What is BMI?

BMI stands for Body Mass Index. It is worked out from your height and weight, and doesn’t take into account age or sex. From your BMI you can work out if you are Underweight, Normal Weight, Overweight or Obese. BMI is a good general guide, however it should not be taken as law. It works on height and weight, and assumes that weight correlates to body fat. On a person that has more muscle than fat (for example, a body builder) then the BMI would not be accurate.
