| RMR - Resting Metabolic Rate
What is RMR & Metabolism?
Resting Metabolic Rate (RMR) represents the number of calories required by the body in 24 hours to maintain vital body functions (such as heart rate, brain functions and breathing). In simple terms, it is the number of calories a person would burn if he or she were awake but at rest all day. RMR can account for up to 75% of a person's total calorie expenditure. Traditionally, it has been difficult to accurately measure RMR, so people have used estimates, as shown above, which can be very inaccurate leaving your success to chance. Why is it necessary to measure RMR? Metabolism is impacted by unique characteristics such as gender, age, weight, body composition, level of fitness, physical activity, eating, stimulations, emotional excitement, stress and gaining and losing weight. A knowledge of RMR is important in managing caloric needs. |
