What’s in a calorie?


‘Calorie’ is a term often used in nutrition, but what does it really mean?


By dictionary terms a calorie is the amount of heat needed to raise the temperature of one gram of water by one degree Celsius. Calories in food provide energy in the form of heat so that our bodies can function. Our bodies store and "burn" calories as fuel.


That’s all well and good but what does that mean for the average person trying to count them?


It all comes down to how calorie ‘dense’ different foods are. In previous blogs we.ve talked about how fat has 9 calories per gram, protein and carbs have 4 calories per gram and alcohol has 7.


If you eat foods high in fats & sugars or alcohol you could be putting more calories in your body than you realise. We found this awesome video that shows you what 200kcals looks like in loads of different types of foods.


Put it this way, you can eat a lot more broccoli & carrots than you can chocolate to get the same amount of calories!
