Answer 1

Calories are a measurement of the energy produced by burning the food we eat, they aren’t units of mass.

The other measurable parts of food, how many grams of this or that (carbs, fats, protein), allows us to measure what the caloric equivalent would be. But the body never knows anything about the idea of Calories.
