Resting Metabolic Rate Testing measures the amount of energy used by the body in a relaxed state. Depending on activity levels, this make up roughly 70% of total daily energy expenditure. Metabolic rate  is influenced by age, gender, hormones, stress levels, how much lean and fat tissue you have and several other factors. 
Lean (muscle) tissue is more metabolically active than fat tissue, so athletes and those with a higher muscle mass generally have higher resting metabolic rates.

How can this RMR result be used?

  • Precisely calculate your energy needs to achieve optimal weight loss or to ensure you are fuelled correctly for your performance needs.

  • Track your RMR over time to see if an exercise program is increasing your body's energy usage.

  • Compare yourself to others of your age, gender, height and weight.

  • Use your results in conjunction with an Accredited Practising Dietitian to formulate an effective eating plan for your lifestyle. 

How does a RMR test work?


Resting metabolic rate (RMR) can be measured by assessing the volume of oxygen you consume at rest. Our state of the art Cosmed Fitmate Pro measures your oxygen intake and carbon dioxide output to calculate how much energy your body is using while at rest.

What happens during the consult?

  • You will be required to lie still on the DEXA table for 10-12 minutes in a quiet room.  

  • You will breathe through a mouthpiece which is very similar to a snorkel and have a nose-peg on. We will give you a trial run to get used to the mouthpiece.

  • Our gas analysis machine will measure the volume of air expired along with the percentages of oxygen and carbon dioxide in the expired air while you are at rest.

Preparation Instructions:

  • Aim for 8 hours sleep the night before the test.

  • Fast for 4 hours prior to the test (you can still drink water). 

  • No exercise for 24 hours prior to the test.

  • No alcohol for 24 hours prior to the test.

  • No shower/bath/sauna/spa for 4 hours prior to the test.

  • Contact us early if you are unwell so we can reschedule the test.
