Question

What is the energy expenditure above and beyond the thermic effect of food in response to conditions such as overfeeding or in response to a traumatic experience called?

a. 24-hour energy expenditure
B. resting energy expenditure
C. physical activity-related energy expenditure
D. resting thermogenesis
E. adaptive thermogenesis

Answer 1

Adaptive thermogenesis is the energy expenditure that occurs beyond the thermic effect of food in response to overfeeding or stressful events, as the body adjusts its basal metabolic rate to maintain energy homeostasis.

Step-by-step explanation:

The energy expenditure above and beyond the thermic effect of food in response to conditions such as overfeeding or a traumatic experience is known as adaptive thermogenesis.

This process reflects the body’s need to adjust its basal metabolic rate (BMR) in response to changes in the environment or the energy balance of the body. The idea is similar to animals adapting to a new environment, where the metabolic rate could change to maintain energy homeostasis.

For instance, increases in energy expenditure due to adaptive thermogenesis can occur during periods of overeating or as a response to stress and cold environments. This adaptation is critical for maintaining a balance between energy intake and energy expenditure.
