Your resting metabolic rate accounts for roughly 70% of the calories you burn on a daily basis. This 15-20 minute RMR test enables you to establish a sensible foundation for your fueling, dieting, or overall nutritional plan so you can dial in and actively manage the number of calories, and macro splits that make the most sense for your training and rest days.
Resting Metabolic Rate Test, RMR Testing
The best way to measure how many calories you burn in a state of rest as well as the % of fats vs. carbohydrates you burn

For Resting Metabolic Rate Testing, we currently use a MedGraphcis Ultima Series CPX, a true clinical-caliber metabolic cart, which is much different than what you will generally find at competing locations. MedGraphics refers to what we call an RMR Test as a ‘Nutrition Assessment,’ which is true. To really understand your caloric and macronutrient requirements, this breath-by-breath analysis is one of the best tools at doing so.
RMR | REE |
- Your Resting Metabolic Rate (RMR) or Resting Energy Expenditure (REE) is the number of calories you burn at rest and when carrying out subconscious metabolic processes, such as breathing.
RQ | RER |
- Your Respiratory Exchange Ratio (RER) or Respiratory Quotient (RQ) is the relationship between the amount of carbon dioxide produced to the amount of oxygen consumed (VC02 / V02).
VCO2 |
- Your VC02 figure is the measurement of Carbon Dioxide you produced during your resting metabolic, breath-by-breath analysis
VO2 |
- Your V02 figure is the measurement of the amount of Oxygen that you consumed during your test.
RMR Test Preparation |
- Fast from solid foods for up to 4 hours
- Refrain from exercise, nicotine or caffeine for 4 hours prior to your RMR test.
- You will wear a neoprene face mask and breathing apparatus.
- Expect your total appointment time to last up to 30 minutes
