It is a good idea to be aware of your estimated energy requirements – these are measured in kilojoules (kJ). Label reading will make more sense if you know how much energy that product is contributing to your total daily requirements. This will influence weight loss, weight gain or weight maintenance.
The kilojoule calculator below will provide you with an estimated requirement based on your age, gender, level of activity and weight. It will also alter your requirements based on your goals for either weight maintenance or weight loss. If you prefer to work with calories, simply divide your generated figure by 4.2. The estimated figure is an approximate guide only. See an Accredited Practicing Dietitian for more specific, tailored requirements.
These energy requirements start from the age of eighteen. This is due to differences in the guidelines for children.
