– if carbohydrates are the body’s energy source, what exactly are calories?

Question

I keep hearing that carbs are the body’s fuel, but fats contain more calories per gram. Surely that means fat is the body’s primary source of fuel?

Answer 1

* Calories are just a measure of energy.
* Coal and uranium have calories….but both would be pretty useless if your body tried to use them for fuel.
* The body uses fat as long term storage whereas it uses carbs for short term energy.
