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 you how many calories you burn at rest, doing nothing more than sitting in a chair. This helps our Coaches discover the training intensity zone that's right for you to maximize your results from exercise.

The RMR or Resting Metabolic Rate test measures the number of calories that your body burns per day at rest. It will also indicate your energy quotient or the ratio of your energy that comes from fat and what portion comes from carbs. This is critical information for nutrition planning for success.

When restricting calories, knowing a baseline RMR is invaluable. KORR Metabolic Analyzers calculate a “weight loss zone” for 1 ½ pound a week weight loss. Or add a Functional Medicine Nutrition plan with our resident expert, Dr. Sheena Joseph who can use your RMR to calculate a caloric goal unique for you.




It is desirable to measure a person’s metabolic rate at a true resting level. To ensure you are at rest, we recommend the following preparation:

  1. Avoid eating a meal 4 hours before the test.

  2. Avoid exercising on the day of testing.

  3. If possible, avoid the use of stimulants such as caffeine prior to testing.

  4. During the test it will be important to get into a comfortable position and relax as much as possible.

  5. Keep lips sealed lightly around the mouthpiece. It is important that all the air breathed out is analyzed by the MetaCheck™.



  1. Your Coach will turn on the MetaCheck ™ and wait while it automatically calibrates. The machine will indicate when calibration is complete. 

  2. Place the nose clip on nose and the mouthpiece in mouth, using his lips to seal around the edges. Relax and breathe normally.

  3. After approximately 10 minutes, the MetaCheck™ will end the test and your Coach will enter your data to compare your results to averages. The results can then be printed out.
