Resting Metabolic Rate Testing

What is Resting Metabolic Rate (RMR)?

  • Metabolism, quite simply, is the conversion of food to energy.
  • Metabolic rate is a measure of how much food, or fat, is converted to energy in a day. Resting metabolic rate (RMR) is the measurement of how much food, or energy, is required to maintain basic body functions such as heartbeat, breathing, and maintenance of body heat while you are in a state of rest. That energy is expressed in calories per day. So an RMR test shows how many calories you burn at rest, doing nothing more than sitting in a chair.

How does it work?

Using direct oxygen measurement.  The KORR Reevue directly measures the concentration of oxygen breathed out by each patient.  The patient merely breathes through a simple mouthpiece as all the exhaled air is collected and analyzed.  Because there is a direct correlation between oxygen consumed and calories burned (4.813 calories for every milliliter of oxygen consumed), an accurate measurement of oxygen consumption is an effective measurement of calorie consumption.

What this session includes:

  • Your specific RMR and a detailed summary of your results
  • Body composition analysis via measurements or skin calipers 
  • Personalized calorie and macro-nutrient recommendations per the patient’s nutrition goals

To prepare for the RMR:

  • Be sure to avoid food, caffeine, exercise, and nicotine for at least 4 hours before the test

This service does not include any meals, grocery lists, or nutrition counseling.
