Your BMI or Body Mass Index is calculated by using your age, gender, height and weight.

If you’re an adult and your BMI score is between 25 and 35, or between 35 and 40 with no health conditions, you can register for our Eat Well, Live Well Programme using our self referral system.

For children, it’s slightly different. Their BMI score is calculated in percentiles and if they are in the 91st percentile or above, they can register for our Your Move Kids Programme today by completing our self referral form and we will get you booked in.
