Question

Quizplus · Accepted Answer

As people age, they tend to have a decrease in muscle mass and metabolic activity, leading to a reduction in their total and resting energy expenditures. This means they require fewer calories to maintain their weight. Sleeping habits, frequency of urination, and changes in appetite are not directly related to this phenomenon.
