Most of us understand that weight management depends upon the energy balance equation: the amount of energy you put into your body (your caloric intake) versus the amount of energy you expend (your TEE). The way to lose body fat is to maintain a negative energy balance. This is accomplished by reducing caloric intake, increasing TEE, or, preferably, a combination of both. Your RMR is dependent primarily on the fat-free part of your body, and accounts for the vast majority of your TEE. So to improve your overall fitness, it is critical to know your RMR.
- Changes in your RMR can be used to influence changes in your body composition. If you lose body fat and replace it with muscle, you should see a steady increase in your RMR. Having your RMR monitored throughout a weight management program can help you track improvements in your muscle mass, thus optimizing your fat loss and fitness/ nutrition program safety.
- RMR can be used to provide an estimate of your TEE, which can help manage your daily caloric intake. While RMR is generally 65% of your TEE, the level of your physical activity can add significant variability to the actual percentage. For this reason, your Daily Activity Level should also be taken into account when determining your TEE. (Sedentary, Low Active, Active, Very Active)
RMR and TEE information should NOT be used for children under 18 years of age, pregnant or lactating women, or individuals in which metabolism may be affected by disease or medication.
