What is Resting Metabolic Rate (RMR)?

Metabolism, quite simply, is the conversion of food to energy. Many factors affect a person’s metabolic rate efficiency:

weight, age, body composition, hormone levels, and gender.


The RMR Test measures the amount of oxygen your body consumes.

Using this measurement it calculates a patient’s Resting Energy Expenditure (REE), commonly referred to as a Resting Metabolic Rate (RMR). This result can help screen for abnormally low metabolic rates and pinpoint the precise caloric intake required for weight loss, maintenance, or weight gain. Applications include nutritional assessments required to treat obesity as well as obesity-related diseases such as metabolic syndrome, sleep disorders, diabetes, and thyroid disorders.

A resting metabolic rate test tells you precisely how many calories your body burns all day just to stay alive. Tip the scale in your favor with real knowledge that will lead to real results. 

Allow us to understand your body’s unique metabolic rate and customize your program by:

• Screening for a slowed metabolism, which can explain frustrated attempts to lose weight.

• Revealing changes in your metabolism to help troubleshoot plateaus. 

• Identifying the precise caloric prescription for maintenance to help you sustain your goal.

Learning to eat to your metabolism will free you to leave conventional diets behind and move on to a healthy and satisfying lifestyle!

Most overweight people are convinced they have a slow metabolism. The truth is that statistically, most overweight and obese individuals have average or higher than average metabolic rates. Taking a measurement removes this excuse. Seeing that their bodies can indeed burn calories can be very encouraging and motivating.


Each individual will react differently to dietary changes which is why a true measurement of RMR is so valuable. Regardless of the method used to lose weight, your RMR will decrease after weight loss. Pinpointing the precise number of calories is key.


When restricting calories, knowing a baseline RMR is invaluable. We calculate a “weight loss zone”  unique for you. For those undergoing significant interventions, such as bariatric surgery, caloric goals of a dietary plan alone may not sustain a patient throughout an entire weight loss regimen. The result is the dreaded “plateau.”


Studies show that hospital stays are reduced an average of 60% when nutritional status is evaluated and needs are met.  RMR testing is recommended for those diagnosed with: hypermetabolism, malnourishment, abnormal body comp (cystic fibrosis, amputees, diabetes or receiving enteral or parental nutrition.

  • Test Preparation Instructions
    THINGS DEFINITELY NOT TO DO Do not eat or drink anything other than water, at least 3 hours before the test. This includes chewing gum. Unless you are fasted, the test results will be contaminated and it will have to be postponed to another date. If you smoke, do not smoke at least 4 hours before the test. Avoid any strenuous activity at least 24 hours before your test. We would not advise working out or going to the gym until after your assessment. THINGS TO DO It’s important to have sufficient rest before your VO2max Exercise test. Continue to take any medication as normal and only delay the timing of your medication if it’s safe to do so. If you delay, remember to bring your medication with you so you can take it after the test. It is especially important to bring your inhaler if you suffer from exercise-induced asthma. If you have any concerns about doing the test, please seek advice from your provider. If you have any metabolic conditions e.x). thyroid issues or diabetes, please ensure you bring some rapidly absorbed carbohydrates to take immediately after your test. You will be fasted pre-test, so you need to avoid the risk of hypoglycaemia. There are always risks associated with exercise and it's essential you complete our health screen prior to your test day. It's extremely important that we have your information and failure to do so may cause your test date to be postponed or cancelled.
  • Information about the mask
    The weird, Bane-like mask is where all the magic happens and is how the machine is able to measure your oxygen intake and usage. Can I do the test without the mask on? No – the mask is how you obtain the data. It’s actually super cool – it isolates both the oxygen you take in and your carbon dioxide output and then uses a machine to measure the oxygen content. Does the mask make you feel claustrophobic? Being honest here, as someone who doesn’t like anything on my face at all, just a little bit. But only when you first put it on – I couldn’t even notice it (aside from being able to see it occasionally when I looked down my cheeks) after the initial set up. Can you breathe normally? Yes! I thought it was going to feel restricted from the looks of it, but you can breathe totally normally when you put it on and when you’re doing the treadmill or cycling portion. What does the mask smell like? Fresh,Clean, Plastic. Ever had something new made of plastic,well thats the smell. Does it pinch the face? No, It will take just a second to adjust the straps to your face(fit testing) but once we have that done, it will be fine fine! Do they clean it first? Yes,We most definitely clean it first. We have special disinfecting wipes and UV sterilzation techniques and equipment that we use to clean all our products
  • Exercise Expectations
    Do I have to run on a treadmill? No! but It’s definitely recommended, If you don’t want to run, just let the staff member know the point is to get you up to your max exercising ability, which may mean different things for different people.In order to get your oxygen consumption measurements, you have to exercise with the mask on for a certain amount of time, at a graduated scale of intensity, while wearing a heart rate monitor, like a Myzone belt. How long do I have to exercise for? You will be working for about 10-15 minutes, which is about the time it takes to cycle through the warm-up and increasing speeds, up to your max level of ability, this is different for everyone! Do I have to wear a heart rate monitor? What if I don’t have one? Yes, in order to get the right data, you’ll need to wear a heart rate monitor, like a Myzone belt. Don’t have one? Don’t worry! The team will have a belt for you and will help you put it on. What kind of data do I get from the test? After your test is completed, you’ll get a printable readout of your data, plus some cool charts, graphs and summaries of what it all means. Ex)I got an outline for a workout plan – basically I have to keep my heart rate under 150 to ensure I burn fat during my workouts.
  • Post Testing Instructions...
    AFTER THE TEST Because you're fasted and likely to have low blood sugar, bring something to eat or drink immediately after the test. If you have specific dietary needs, bring some appropriate snacks to consume. If you have a medical condition, please bring your medication to take immediately after the test (if required) e.x). an inhaler for exercise-induced asthma. The test results will be explained in detail and you will presented with a full analysis and review. Your report will either be printed immediately or emailed to you by the close of business .
  • Safety Assurance
    All of our metabolic tests are conducted by certified and insured health & fitness professionals. Latex Allergy-There is a rubber ring in the mask to support a component used to measure your breathing. This ring could rest against your lip and may be an issue if you have a latex allergy or intolerance. Claustrophobia-The mask fits snugly over your face. This may be an issue if you are claustrophobic. Cardiac Issues-Due to its very nature of the test,it places your body under increasing stress. There are inherent risks associated with exercising, which include (but are not limited to), cardiac events, stroke, breathing difficulties, joint issues and death. Fainting/Health Issues-Please be sure to bring a post exercise snack,I advise you to eat simple carbohydrates (high Glycaemic Index) after his VO2max test. At Most 10 minutes after the test, to avoid illness, and fainting. Respiratory Issues-The mask fits tightly over the face and often restricts nasal breathing, forcing you to breathe through your mouth. The tests are conducted in an air conditioned environment, which makes the air drier than normal and may irritate your throat and cause breathing issues. If you have exercise-induced asthma, please bring your inhaler and any prescribed medication. Please complete our short Health Screen before your test so we can identify any potential safety issues.
