Energy

All foods are made of fats, protein, carbohydrate and water.  Fats, protein and carbohydrates all provide the body with the energy or kilojoules needed to function and help you go about your daily activities.

The amount of kilojoules you consume should be in balance with the amount of energy you expend through physical activity during the day.  If the amount of energy (kilojoules) you take in through food and drinks is less than you are using up through physical activity and daily activities, then you will lose weight. And if it is more, then you will gain weight.

The simplest way to keep your kilojoules in check is by following our healthy eating guidelines. Go to our healthy eating guidelines.

What's a reasonable amount?
Kilojoules are listed  with energy on the food label. When snacking, adults should choose snacks that contain no more than 600kJ. For children snacks should be up to 300kJ – that generally equates to one piece of fruit, a slice of raisin bread or half a tub of yoghurt. Stick to one or two snacks a day.

Make smart food choices by choosing foods that are nutritious. Changing the way you cook and prepare your meals can help too.

Healthy heart tip
Products described on the label as “light” or “lite” may be lower in fat or sugar than other products but it may not be lower in kilojoules compared to a regular product. Do a quick double check by comparing nutrition information on the back of the label before you make your purchase.
