In nutrition, what does the term 'kcal used' refer to?

Explanation:
In nutrition, kcal used refers to the energy the body expends—the calories it burns to stay alive and to perform activities. This is the total energy out, not the energy we consume. So it covers resting metabolic processes plus the energy spent on movement and digestion. It isn’t about calories eaten (energy intake) or just the resting part (basal energy expenditure) alone, though those are components of total energy expenditure. Think of kcal used as the calories burned during everything your body does.
