What is the definition of resting energy expenditure (REE)?

Question

Quizplus · Accepted Answer

Resting energy expenditure (REE) is the amount of kcalories required for a 24-hour period by the body during a non-active period, which includes basal metabolic rate (BMR) as well as energy needed for digestion, absorption, and metabolism of food. It is usually measured by indirect calorimetry while the person is at rest and in a fasting and thermoneutral state. Option A is incorrect as REE is not only associated with sleep, but also with other periods of inactivity. Option B is incorrect as it does not include the 8-hour period of sleep. Option D is incorrect as REE includes energy needed for digestion and absorption, which is not present during a period of fasting.
