Question

How do adults energy needs change as they get older?

Their energy needs are usually higher.
Their energy needs stay the same.
Their energy needs are typically lower.
Their energy needs vary greatly.

Answer 1

As adults get older, their energy needs generally decrease due to a decrease in basal metabolic rate (BMR), muscle mass, and physical activity.

Step-by-step explanation:

As adults get older, their energy needs generally decrease. This decrease is mainly due to a decrease in basal metabolic rate (BMR), which is the amount of energy the body needs at rest to perform basic functions such as breathing and maintaining body temperature. The decrease in BMR is primarily caused by a decrease in muscle mass and an increase in fat mass that occurs with age. Additionally, older adults tend to be less physically active, which further contributes to the decrease in energy needs.
