What does this mean?
This calculation shows you approximately how many kilojoules you need each day to maintain your weight or get closer to your weight goal over a healthy period.
Everyone is different, and this is just a starting point. A good way to tell whether you are consuming the right number of kilojoules is whether you are gaining or losing weight.
The good news is that small changes can make a big difference. You can find more information on exercise and healthy eating on our website.
