Your resting metabolism, measured
A calorie target starts
with understanding your burn.
A calculator predicts your resting calorie needs from details like age, height and weight. An RMR test measures your breathing to calculate the energy your body uses at rest.
MEASURED RESTING CALORIE BURNWhat you walk away knowing
Your resting burn.
A clearer starting point.
You lie still and breathe normally through a mask or hood. We analyse the oxygen you use and the carbon dioxide you breathe out, then put your result into context with your activity and goals.
- Your measured resting calorie burnKnow your RMR rather than relying only on a formula.
- How your result compares with predictionsSee the difference between your measurement and standard equations.
- Personal calorie and protein targetsGet a starting point for your goals, with daily calorie needs estimated from your RMR and activity.
- A digital report to refer back toKeep your result and targets in your dashboard, or share them with your coach or dietitian.
RMR is your energy use at rest, not your total daily calorie burn. Full RMR service details ↗
Why test?

What is resting metabolic rate?
RMR is the energy your body uses at rest to support essential functions. The test analyses your oxygen use and carbon dioxide production to calculate resting calorie burn, rather than predicting it from a formula.
Will this tell me exactly how much to eat?
It measures resting calorie burn, not your total daily energy use. We combine your measured RMR with your activity and goals to estimate daily needs and a calorie starting point. Your real-world progress helps refine that estimate over time.
How do I prepare?
Follow the instructions in your booking confirmation. Our current RMR guidance is to fast for four hours, avoid caffeine and nicotine for four hours, and avoid exercise for twelve hours before testing. Arrive rested and normally hydrated.
If fasting may be unsuitable for you, or you have a condition or medication that could affect testing, contact us before booking. Do not change prescribed medication without advice from your doctor. Read the RMR service information ↗
Do I have to exercise? How long does it take?
No exercise is involved in the standalone RMR test. You lie still and breathe normally through a mask or hood. Allow 30 minutes for the appointment, including setup, measurement and the results consultation. Metabolic Baseline takes 60 minutes and Full Lab takes 90 minutes; Full Lab also includes a VO2 Max exercise test.
Can this diagnose a slow metabolism or a medical condition?
The test shows your measured resting calorie burn and how it compares with standard predictions. It does not diagnose thyroid disease or explain every cause of weight change, fatigue or a training plateau. Speak with your doctor about symptoms or medical concerns.
Should I book RMR, Metabolic Baseline or Full Lab?
Choose RMR for resting calorie burn and personal calorie targets. Choose Metabolic Baseline to add a DEXA scan measuring body composition. Choose Full Lab to include DEXA, RMR and VO2 Max fitness testing with training zones.
No GP referral is needed. DEXA must not be performed during pregnancy; speak with us if you are pregnant or might be pregnant. Full Lab requires pre-exercise screening, and medical clearance may be needed. Follow the preparation guidance for the package you book.
