The art of the calorie is a pretty confusing topic, especially coming into the New Year as everyone is counting theirs– This comprehensive image should help clarify things.
To make things even more confusing, a “calorie” is the energy it takes to raise one gram of water by 1 deg C, but a “food calorie” is 1000x this amount (the energy it takes to raise one kilogram of water by 1 deg C). Food calories are sometimes called “Calories” with a capital C, “Kilocalories,” or “Kcals.” If you are reading food labels, then you’re reading about food calories.
