Resting Metabolic Rate (RMR) is indeed influenced by various factors, and among the options you've provided, age is a significant one.
- Age: As people age, their RMR tends to decrease due to factors such as loss of muscle mass and hormonal changes. This means that older individuals may have a lower calorie burn at rest compared to younger individuals, all else being equal.
The other factors you mentioned—daily values, appetite, and hunger—don't directly affect RMR in the same way that age does:
- Daily Values: This typically refers to nutritional guidelines and daily recommended intake, which doesn’t directly impact RMR but can affect overall energy balance and metabolic health.
- Appetite and Hunger: While these can influence food intake and energy expenditure indirectly, they don't have a direct physiological effect on RMR itself.
In summary, among the factors listed, age is the most relevant to changes in resting metabolic rate.
