Resting Metabolic Rate Testing
Forget generic calorie calculators and one-size-fits-all nutrition plans – discover how your unique metabolism actually works with precise, scientific measurement.
Our RMR testing uses indirect calorimetry – the gold standard in metabolic tests – to reveal what’s happening inside your body at rest. It shows everything from how efficiently you burn fat to how well your heart and lungs function when you're not exercising.
Think of it as a comprehensive snapshot of your metabolic health.
If you are serious about changing your body composition, it begins with knowing your true baseline energy expenditure. You'll understand exactly how many calories your body needs for maintenance, fat loss, or muscle gain – without any guesswork.
The test also reveals your personal fat-burning efficiency, metabolic flexibility, and cellular performance.
If you want to optimise your nutrition with precision rather than following generic advice, RMR testing provides the metabolic blueprint you need.
Our comprehensive reports translate complex data into actionable insights about your heart fitness, lung capacity, and cellular health that can transform your approach to nutrition and training.

Why it helps
Have you ever followed a diet plan that worked wonders for someone else but did nothing for you? Or felt frustrated when your energy levels crash despite eating what you thought was the "right" amount?
An RMR test cuts through the confusion by revealing how your unique metabolism actually functions. It shows you precisely how many calories your body needs and how efficiently it uses different fuel sources like fat and carbohydrates – both at rest and as a foundation for physical activity.
This insight can be particularly helpful whether your goal is weight gain, fat loss, muscle preservation, or enhancing athletic performance.
When you understand your true metabolic baseline, nutrition becomes less about guesswork and more about precision – helping you make confident decisions about your diet, avoid unnecessary restrictions, and finally achieve the fitness goals you've been working towards.
What happens during your test?
Unlike traditional methods involving complicated equipment or lengthy protocols, our RMR testing process is simple, comfortable, and completely non-invasive.
You'll lie back on a comfortable couch in a quiet, temperature-controlled room whilst wearing our specialised breathing mask.
The mask is lightweight and designed for comfort while it precisely measures your oxygen consumption and carbon dioxide production - the core principle of indirect calorimetry.
The test takes approximately 15 minutes, during which you'll simply relax and breathe normally. This resting state allows us to establish your true metabolic baseline—how your body functions when completely at rest.
Our system analyses your breathing patterns to determine:
-
Exactly how many calories your body burns at rest
-
How efficiently you use fat versus carbohydrates for fuel
-
The overall health of your metabolism
All this from just breathing normally!

-
Personalised Nutrition Guidelines: Get specific calorie targets for both training and rest days, with recommended macronutrient splits tailored to your unique metabolic profile
-
Health Insights Dashboard: View your scores across key metrics including heart fitness, lung utilisation, metabolic rate, and fat-burning efficiency – with clear explanations of what each means for your overall health
-
Actionable Recommendations: Receive practical exercise, nutrition and lifestyle recommendations to improve any areas that may be limiting your progress or health
-
Optional Specialist Consultation: For those wanting to dive deeper into their results, book an extended session with our metabolic specialist to explore the nuances of your report and get personalised advice for your specific goals
Yes! The test simply measures your breathing patterns while at rest. There's no radiation, electrical impulses, or invasive procedures involved. It's completely safe for everyone, including pregnant women, those with pacemakers, or people with medical conditions.
For the most accurate results, we recommend:
-
Fasting for 6-12 hours before your test
-
Abstaining from alcohol, nicotine, and caffeine for at least 2 hours
-
No exercise for at least 24 hours; take a rest day before the test
-
Getting a good night's sleep
-
Arriving 10-15 minutes early to allow your body to fully relax before testing
-
The actual breathing measurement takes about 15 minutes. With preparation time and a brief review of preliminary findings, you should allow approximately 45 minutes for your appointment.
For those tracking changes to their metabolism (for example, during weight loss or athletic training), we recommend testing every 3-4 months. However, you can choose a schedule that suits your specific goals and budget. Some clients test seasonally to adjust their nutrition throughout the year.
Most people find the mask very comfortable. It's lightweight and designed to fit securely without feeling restrictive. You'll simply breathe normally through the mask while relaxing on our comfortable couch.
If you experience claustrophobia or anxiety about wearing masks, please let us know beforehand.
Please note: the mask only covers your nose and mouth (not your eyes), and you'll be in a relaxed, controlled environment with our specialist nearby at all times. We can also arrange a brief trial with the mask before your appointment to ensure you feel comfortable proceeding with the full test.
FAQ
What Our
Clients Are Saying
"My trainer kept saying I shouldn't focus on calories, but I never understood why until my RMR test. Turns out I was seriously undereating on training days! Making those adjustments has completely transformed my energy levels and recovery."
James T.
“I'd been following the same diet as my training partner with totally different results. The test showed my metabolism was actually burning significantly more fat than hers. Now we both have personalised plans that actually work for our bodies.”
Sarah K..
"At 52, I was frustrated that the nutrition advice that used to work wasn't cutting it anymore. The RMR test showed that my calories and macros I was used to were way off."
Robert C.
“As a fairly serious cyclist, I thought I knew my body pretty well. The metabolic test results told me that my fat-burning efficiency was actually quite poor despite my fitness level. After adjusting my training zones based on the results, my endurance has improved a lot and I'm not bonking on long rides anymore.”
