Kilojoules (kJ)

Here in Australia, most of our shopping shelve products will have an ingredients section somewhere on the label (nutritional information panel). Among all the confusing words listed on there is one little important term – Kilojoules (kJ)

Kilojoules are a way to measure the amount of energy a food or drink contains, and also the amount of energy the body uses during an activity. Here in Australia the recommended daily intake of energy for a average adult is 8,700kJ to maintain a healthy weight.

Remember this is only a guide and doesn’t take in consideration various factors for each individual such as:

  • how much exercise/actively you undertake
  • how much muscle weight you have
  • if you are at an age of growth (developing)
  • your individual age, height, gender and weight

Because both food and drinks contain energy (kJ) sometimes we can find it hard to tell how many kilojoules we are consuming.

In general:

  • alcohol, fats and sugars are high in kilojoules
  • carbohydrates and protein provide a moderate amount of kilojoules
  • fruits and vegetables are lower in kilojoules
  • dietary fibre is also low in kilojoules
  • good old fashioned water has no kilojoules (unless they ‘add’ stuff)

The main idea to take away is that balancing kilojoule intake is the key. If you take in more energy (kJ) than you use, you will store that excess energy as fat. Hence, to loose any extra fat, you need to take in less energy than you would normally consume or partake in more exercise
