How many kilojoules do I need?
Our daily kilojoule requirements vary based on things like:
- how much physical activity you do, and what type
- your height, weight, age and gender
- the amount muscle and fat you have
- whether you are pregnant or breastfeeding
- genetics and health.
The average daily intake for an adult is 8700kj – so keep this in mind when you’re checking labels on packaged foods and menus. Learn more about how to read food labels and menus.
If you think you or member of your family may be above a healthy weight, consult a qualified health professional.

‘Burning’ kilojoules
We are using energy all day – even while we sleep. Our bodies need kilojoules to function. But if we consume more kilojoules than our bodies use, the spare energy can lead to excess weight gain.
When we are active, our bodies 'burn' or use up more energy. Regular physical activity helps you maintain a healthy weight and overall good health. It can also reduce your risk of chronic diseases and support your
mental health. Check out these
small steps to start getting more active.
