How much energy, calories or kilojoules?
I’m confused what’s the difference between energy, calories and kilojoules? You’re not alone because any of these three terms are used when measuring what and how much we eat. Here’s the low-down on what these terms mean and how much energy you should aim for. We need to consume food and drink each day to provide the nutrients that give us energy to fuel our body. The fat and carbohydrate in our diet is chemically converted into energy to use to breath, digest, walk and other normal processes. The challenge is to eat and drink enough energy to fuel our body to do the things we want to do, but not too much that the excess (spare energy) gets stored for later. We put on body fat when this happens. A kilojoule (kJ) is simply a unit of energy. So is a calorie (Cal). In Australia we use kJ as our metric unit rather than Cal, which can be thought of as an older, imperial unit of measurement. This is just like using kilometres to measure distance, rather than miles. You can convert kJ to Cal
