The loss of muscle mass due to physical inactivity will lead to a decrease in ______,further exacerbating the age-related decrease in total energy expenditure and accumulation of fat.

Question

Quizplus · Accepted Answer

Resting energy expenditure (REE) is the amount of energy needed to maintain basic bodily functions at rest. Muscle is a metabolically active tissue that contributes to REE, so the loss of muscle mass due to physical inactivity will lead to a decrease in REE, making it harder to maintain energy balance and more likely to accumulate fat. The other options (A, C, D) are not directly related to the impact of muscle loss on energy expenditure.
