ok so to my understandings rmr is when your metabolism rest?
Yes, that's correct. Resting metabolic rate (RMR) is the amount of energy expended by an individual while at rest. It represents the energy required for basic bodily functions such as maintaining organ function, regulating body temperature, and supporting brain activity. RMR accounts for the majority of the calories burned by an individual throughout the day, typically contributing about 60-75% of their total energy expenditure. As RMR is influenced by various factors, including age, body composition, and hormone levels, it can vary among individuals.
can you break it down
Certainly! Resting metabolic rate (RMR) is the number of calories your body burns while at rest, which means when you are not engaged in any physical activity. Here's a breakdown:
1. Basic bodily functions: RMR represents the energy required for basic bodily functions such as breathing, circulating blood, and maintaining organ function. These activities require a certain amount of energy regardless of whether you are active or at rest.
2. Body composition: RMR is influenced by your body composition, particularly your muscle mass. Muscle tissue requires more energy to maintain than fat tissue, so individuals with more muscle mass tend to have a higher RMR. This is because muscles are metabolically active and require energy even at rest.
3. Age: RMR tends to decrease with age. This is because as we get older, we tend to lose muscle mass and have a decrease in certain hormone levels (such as growth hormone and testosterone) that influence metabolism. Therefore, older individuals generally have a lower RMR compared to younger individuals.
4. Hormone levels: Hormones, such as thyroid hormones and cortisol, play a role in regulating metabolism. Imbalances in these hormones can affect RMR. For example, an underactive thyroid (hypothyroidism) can lead to a lower RMR and slower metabolism.
5. Genetics: RMR can also be influenced by genetic factors. Some individuals may naturally have a higher or lower RMR based on their genetic makeup.
It's important to note that RMR is just one component of energy expenditure. Physical activity, thermic effect of food (energy expended during digestion), and non-exercise activity thermogenesis (NEAT) also contribute to overall energy expenditure.
