RMR (Resting metabolic rate): Do You Know How Many Calories You Burn?

RMR and MetabolismWhat is metabolism?

Metabolism is the body's process of converting food and stored fat into energy. This energy is used to stay warm, move around and keep vital organs functioning. Metabolism is typically measured in calories.

What is RMR?

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 energy expenditure.

Why is it necessary to measure RMR?

Metabolism is impacted by unique characteristics such as gender, age, weight, body composition (amount of muscle versus fat), level of fitness, physical activity, eating, stimulants, emotional excitement, stress and gaining and losing weight. A knowledge of RMR is important in managing caloric needs.

Metabolic assessment is obtained with a simple measurement using an indirect calorimeter (BodyGem). The test requires you to breathe into the BodyGem device for ten minutes to measure your oxygen consumption. Once testing is completed you and your dietitian will have an accurate calorie budget to work with.
