Which of the following statements most accurately captures an aspect of the basal metabolic rate (BMR)?
A)
The resting BMR constitutes a small fraction of the total body energy needs.
B)
Females tend to have a lower BMR than males due to a smaller skeletal muscle mass.
C)
Variations in muscle mass account for much of the differences in the BMR that exist between individuals.
D)
The BMR remains consistent throughout the life span.
Ans:
C
Feedback:
Body size and skeletal muscle mass account for most of the individual variations in BMR that exist between individuals. The resting BMR accounts for 50% to 70 % of the total body energy needs, and increased quantities of adipose tissue account for the lower average BMR in females as compared to males. BMR decreases with age.
