RMR stands for Resting Metabolic Rate. It is the measure of energy you expend (or, calories you burn) while at rest. During the state of rest your body will only expend a sufficient amount of energy to maintain the basic functions of your body, such as: heart, lungs, nervous system, brain, liver, and other vital organs.
Your Activity-Adjusted RMR (McArdle at al 1996) is an estimated total expenditure of your body's energy in a single day, which is calculated using a factor to adjust your RMR for activity. Activities may include, but are not limited to: rest, walking, talking, working, exercise, and all movement you perform throughout the day. This estimate includes your "at rest" energy expenditure. It is the total estimated number of calories you burn in a 24-hour period (including rest and physical activity).
