Energy needs decline with advancing age partly because:
A)sarcopenia is not significant in later years.
B)organs actually get smaller and so require less energy.
C)older people usually increase their physical activity.
D)basal metabolic rate declines as people age.
E)older people are better able to absorb energy from foods.

Question

Quizplus · Accepted Answer

As people age, their basal metabolic rate declines due to a decrease in muscle mass and an increase in fat mass. This leads to a decreased need for calories and energy, contributing to the decline in energy needs with advancing age. choices A, B, C, and E are incorrect as sarcopenia is a significant issue in later years, organs do not get smaller enough to significantly affect energy needs, physical activity usually decreases with age, and absorption of energy from foods does not improve with age.
