Final answer:
RMR, or resting metabolic rate, depends on factors such as body composition, age, gender, and genetics. Lastly, genetics can influence our RMR, as some individuals are naturally predisposed to have a faster or slower metabolism.
Step-by-step explanation
RMR, which stands for Resting Metabolic Rate, depends on various factors including body composition, age, gender, and genetics.
It refers to the number of calories your body needs to perform basic functions at rest.
Body composition, specifically the amount of lean muscle mass, plays a significant role as muscle requires more energy to maintain compared to fat.
Age also affects RMR as our metabolism tends to slow down as we get older.
Gender differences exist as well, with males generally having a higher RMR compared to females due to higher lean muscle mass.
Lastly, genetics can influence our RMR, as some individuals are naturally predisposed to have a faster or slower metabolism.
