Daily Intake Percentage

The foods we eat provides our body with energy which is measured in kilojoules (kJ) and used to be measured in calories. Fat, protein, carbohydrate, dietary fibre and alcohol in foods all provide energy, but in different amounts.

Energy is like fuel in a car – it’s what keeps our bodies going and is needed for vital functions like movement, body functions, growth and repair.

However, energy can be stored by the body as fat cells. If the amount of energy (kilojoules) you eat in food and drinks is more than you are using up through physical activity and daily activities then you will gain weight. Energy requirements vary according to age, gender, body size, weight and physical activity levels. Click here to see how much energy you need.
