Different foods and drinks contain different amounts of kilojoules, depending on: the ingredients how the food or drink is prepared size of the serving. Our Daily Needs kJ is the average daily energy intake for an Australian adult. How many kilojoules a person needs each day differs, depending on your: age sex body size activity level life stage for example pregnancy.

Healthy food and drink choices The table below shows us how our healthy food and drink choices can make a big difference in the number of kilojoules we eat. When excess energy is consumed above our daily energy needs it gets stored as fat.

This could increase the risk of becoming overweight or obese if not balanced with exercise. The food we eat contains varying amounts of energy depending on how much fat, carbohydrates, protein or alcohol it contains. Each gram of fat provides 37kJ in comparison to carbohydrates and proteins, which contain 16kJ and 17kJ respectively.

Eating too much fat could quickly lead to excessive kilojoule energy intake and consequent weight gain. Phone 02 or for those outside of Sydney. Summary Read the full fact sheet. On this page. Energy as kilojoules Kilojoules in food Our energy requirements vary Where to get help.

Energy as kilojoules In Australia, we use kilojoules kJ to measure how much energy people get from consuming a food or drink. Food energy used to be measured in Calories Cal and some countries still use those units. It can be hard to tell how many kilojoules are in each food just by looking, but in general: Fats and alcohol are high in kilojoules. Protein and carbohydrates provide moderate amounts of kilojoules. Dietary fibre is low in kilojoules. Water provides no kilojoules energy.

Foods such as fruits, vegetables and legumes are less energy-dense foods lower in kilojoules. Foods that are high in fats, added sugars or alcohol are by far the most energy-dense foods highest in kilojoules. Our energy requirements vary Your energy kJ needs each day and how much energy you burn vary and depend on: how active you are in your daily activities the amount and type of exercise you do your height and weight your sex — men generally have higher energy requirements than women, because they have more muscle tissue your body composition — muscle tissue has a big appetite for kilojoules.

Food that we eat gives us energy to go through our day. It gives us energy by providing energy to the cells inside our body. Carbohydrates in food are used first.

When they are all used up, the body then uses fats, and then proteins as energy sources. So carbohydrates, fats and proteins provide energy to our bodies through the foods that we eat. The energy in the food that we it is measured in units of kilocalories or Calories.

The Calorie Cal, with an uppercase C used to measure the nutrition in food is actually calories cal with a lowercase c or 1 kilocalorie kcal.

While the Calorie unit is used widely in the U.
