Dear Reader
As I tried to explain in this week's DietDoc Topic, kilojoules are a metric unit used to measure energy. So if we say that a food contains 100 kJ, this means that you will obtain 100 units of energy from that food. Carbohydrates are macronutrients like protein and fat. These 3 macronutrients and water make up the bulk of any food. So you may see that a food label lists the Nutritive Composition of a food as 5 g protein, 5 g fat and 60 g carbohydrate per 100g, Thus if you eat this food your body will obtain 60g of carbohydrate to use as a source of energy. Every gram of carbohydrate and every gram of protein contains 17 kJ, while fat contain 37 kJ per gram - quite a difference, which is why we recommend that you reduce fat intake to lose weight.
Best regards
