When trying to lose weight, we hear a lot about calories and kilojoules, but what exactly are they and what does it mean for our eating habits?

Calories Vs Kilojoules

Both calories and kilojoules are units of measurement for how much energy a food contains. In Australia, our scientific community tend to use kilojoules (kJ) to measure units of energy in food and drink, however most consumers will focus on calories when looking into healthy eating and weight loss. The only difference between the calories and kilojoules is simply the scale – similar to the difference between inches and centimetres.

1 Calorie = 4.2 kJs

Or

1 kJ = 0.2 Calories

 

Kilojoules in Food

How many kilojoules a food has is dependent on a wide variety of factors including the amount of protein, fat, size, and carbohydrates it has.

How many calories do you need?

Your energy needs depend on a variety of factors including:

– what your goals are

– how much energy you are using

– Your gender

–  whether or not you’re pregnant

–  Your age

– Your height and weight
