Resting metabolic rate (RMR) can be affected by:
A. Age - Yes, RMR typically decreases with age due to a decrease in lean body mass and hormonal changes.
B. Daily values - This option is a bit vague, but generally, RMR is not directly affected by daily nutritional values in the short term, though overall nutrition can impact metabolic health.
C. Appetite - RMR is not directly influenced by appetite; however, long-term changes in diet and energy intake can affect metabolism.
D. Hunger - Similar to appetite, hunger itself does not directly affect RMR, although chronic energy deficit or surplus can potentially lead to changes in metabolic rate over time.
The most relevant answer here would be A. Age.
