Resting Metabolic Rate

Resting Metabolic Rate (RMR) is the minimum number of calories your body needs to support its basic physiological functions, including breathing, circulating blood and all of the numerous biochemical reactions required to keep you alive. Your RMR is generally 60-75% of your total daily caloric expenditure.Knowing the minimum number of calories your body needs is important if you’re trying to lose, gain or maintain your current weight.


When RMR is calculated by estimations it is subject to significant error – as much as 20% to 25%.* This can lead to an inappropriate nutritional plan for you. The “Gold standard” for determining resting metabolism is through indirect calorimetry using a metabolic analyzer which measures both VO2 and VCO2.


Everyone’s metabolism and caloric needs are different. 

Your body’s metabolism is affected by:


  • Age
  • Gender
  • Height
  • Body Composition
  • Activity Level
  • Other physical and environmental factors

Eliminate the frustration and dial in your caloric needs.

Optimize your athletic performance and weight loss strategy by understanding how many calories you burn at rest and what percentage of fat to carbs you are burning.

The Resting Metabolic Rate assessment is a simple process. 

It’s the easiest test you’ll ever take. It involves wearing a comfortable mask while sitting in a chair and breathing. That’s it. 

Really, There is no pass or fail standard, no studying or preparation you can do beforehand. The assessment gives you a snapshot of where you and your body are today, in terms of how your body burns fuel when it is at rest.

A Resting Metabolic Rate assessment measures
 the amount of calories your body needs to function, including everything from regulating your body’s hormones to thinking the thoughts that run through your mind.

All that information comes from measuring your mix of oxygen and carbon dioxide in your breath.

When you schedule for your assessment you’ll receive a personal assessment pack that is yours to keep. It includes a comfortable, somewhat stretchy, mask and the airflow sensors and accessories that are used during the assessment. It also includes an explanation of how and why a metabolic assessment makes such a difference in your fitness program. Everything is packaged in a nylon drawstring bag, which makes it easy to store your mask so you’ll have it for follow-up assessments.

During your assessment. 

Your fitness professional will help you position the mask over your nose and mouth, and then you get to kick back in a groovy, comfy chair for about 15 minutes. Hang out, breathe, try to stay awake. That’s all there is to it. (Your assessment will be most accurate if you’ve fasted for 12 hours (only water) and are well rested. Mornings are a great time for this assessment.)


The information gained from your assessment is powerful because it comes from technologies that have been proven effective for decades. The type of metabolic assessment offered is used by physicians, who rely on it for the health of their patients, and by Olympians, who rely on it to achieve world-class athletic performance.
