Stop guessing your calorie target from an app. Clinical Resting Metabolic Rate testing is now available in Altrincham, measuring exactly how many calories your body burns at rest at our Evolve Fitness venue in Timperley. It is the real baseline every nutrition plan should start from. Full medical report within 48 hours.
From £110 per test
Metabolic cart precision · No GP referral needed · Full medical report within 48 hours
An RMR test on its own tells you exactly how many calories your body burns at rest, the true baseline that standard calorie calculators estimate and often get wrong by 200–400 kcal per day. Pairing it with a DEXA scan in the same session at Evolve Fitness adds your full body composition picture: fat mass, lean mass and visceral fat to medical precision. Most clients who book for nutrition or weight management combine both, because knowing your metabolic rate without knowing your body composition (or vice versa) gives you half an answer.

Standard calorie calculators estimate your metabolic rate from population averages. For any individual they can be off by 200–400 kcal per day, enough to make the difference between losing weight and maintaining it, or between fuelling right for a training block and running on empty. Until TELOMYX, getting a properly calibrated RMR test near Altrincham meant a Manchester sports-science lab or a specialist clinic with limited availability. We fixed that by bringing clinical metabolic cart testing directly to Evolve Fitness in Timperley, with free parking and quick access from across South Trafford.
Every standard calorie calculator (Harris-Benedict, Mifflin-St Jeor, MyFitnessPal) uses population-average formulas. RMR testing measures your actual metabolic rate from your exhaled breath. For the same height and weight, individual RMR can vary by 400 kcal or more. We test at Evolve Fitness, Timperley (WA14 1TD), with free parking and easy access from Hale, Bowdon and Sale.
Within 48 hours of your test, with your RMR result, estimated TDEE at multiple activity levels, respiratory exchange ratio and goal-specific interpretation.
Unlike DEXA, an RMR test requires no medical referral. Book a slot, follow the pre-test guidelines and turn up. No GP appointment, no waitlist, no extra steps.
Clinically led from day one. No supplements, no transformations, no upsells. Just the data and what it means for your specific biology and goals.
Recent reviews from clients who had an RMR test at our Altrincham venue. Verified via Google Business Profile.
★★★★★
"Five months of tracking calories and the scales hadn't moved. My RMR came back about 270 calories below every calculator I'd used, which explained the whole thing. Finally have a real number to build my plan around instead of an average that clearly wasn't me."
★★★★★
"Running high mileage for the Manchester Marathon and wanted to be sure I was fuelling enough. The RMR result anchored the whole nutrition plan and I knew exactly what to eat on easy days versus long-run days. Got to the start line feeling strong rather than depleted."
★★★★★
"Perimenopause arrived and suddenly the things that always worked just stopped. The RMR test confirmed my metabolic rate had dropped more than I realised and made months of frustration finally make sense. Gave me a concrete number to work from with my dietitian."
Six things every Altrincham RMR client gets, as standard.
Your exact calorie burn at complete rest, the true baseline and not a population-average estimate. The number every nutrition plan should start from. Measured at Evolve Fitness, Timperley (WA14 1TD), using a clinical metabolic cart.
Your RMR scaled to your actual activity level, giving you a realistic daily calorie target for maintenance, fat loss or muscle gain.
Shows whether your body is predominantly burning fat or carbohydrate at rest, relevant context for metabolic health and nutrition strategy.
Emailed within 48 hours with your results, reference ranges and interpretation. Share it with your dietitian, coach or GP.
Alongside your report, a member of the TELOMYX team will give you specific recommendations based on your own metabolism and goals, so you know what to actually do with your results.

Book online in 60 seconds. Pick a slot at Evolve Fitness, Timperley (WA14 1TD). No referral needed. Just book, follow the pre-test guidelines and turn up.
Read your pre-test guidelines carefully. You will receive a confirmation email with the full pre-test guidelines for an RMR test. These cover fasting requirements (typically 4 to 6 hours with no food or caloric drinks), no caffeine beforehand, and no intense exercise for at least 12 hours before your appointment. Please read them in full. The guidelines matter more for RMR than for almost any other test, as recent food, caffeine or activity directly elevates your metabolic rate and will skew the result upward.
Arrive and get tested. A member of the TELOMYX team meets you at Evolve Fitness reception. You will be set up on a reclined couch and fitted with a transparent metabolic canopy that sits over your head and upper body. You lie still and breathe normally for around 20 minutes while the system analyses your exhaled gases, measuring your oxygen consumption and CO2 production to calculate exactly how much energy your body burns at rest.
Results walkthrough and targeted advice. A member of the TELOMYX team walks you through your RMR result, your estimated total daily energy expenditure at different activity levels, and your respiratory exchange ratio. You will get specific recommendations based on your own metabolism and goals, not a generic printout explanation but actionable advice tailored to you.
Full medical PDF report within 48 hours. Comprehensive report emailed to you with your RMR, TDEE estimates at multiple activity levels, respiratory exchange ratio and interpretation. Ready to share with your dietitian, nutritionist, coach or GP. Includes reference ranges so you can benchmark your metabolic rate against expected values for your age and sex.
RMR tells you how many calories your body burns. Pair it with DEXA for body composition and bone density, or VO2 Max for your aerobic fitness ceiling.

Calorie calculators (Harris-Benedict, Mifflin-St Jeor, MyFitnessPal estimates) use population-average formulas. For any individual they can be off by 200 to 500 kcal per day, enough to undermine months of dieting or training. An RMR test measures your actual oxygen consumption and CO2 production, which is a direct physiological measurement, not an estimate. If you are making nutritional decisions based on a calculator, you are working from a guess.
Yes. You should fast for at least 4 to 6 hours before your test: no food, no caloric drinks, no caffeine. Avoid intense exercise for at least 12 hours beforehand and arrive in a rested, calm state. Full pre-test guidelines are sent when you book. Following them matters more for RMR than for almost any other test: recent food, caffeine and exercise all temporarily elevate your metabolic rate and will push your result above your true baseline.
Your RMR (in kcal/day) is the number of calories your body burns at complete rest. It accounts for roughly 60 to 70% of total daily energy expenditure for most people. From your RMR, your report includes estimated total daily energy expenditure (TDEE) at different activity levels, giving you a realistic daily calorie target for maintenance, fat loss or muscle gain. Your result also includes your respiratory exchange ratio (RER), which indicates whether your body is predominantly burning fat or carbohydrate at rest.
Several factors can depress RMR below population-average estimates: prolonged calorie restriction (metabolic adaptation), low muscle mass, thyroid dysfunction, certain medications, and age-related hormonal changes, particularly in women around perimenopause and menopause. If your measured RMR comes back lower than predicted, the TELOMYX team will discuss the likely contributing factors and what that means for your calorie targets going forward.
It depends on your goal. If your primary question is about calorie targets or why your current approach is not working, RMR alone answers it. If you also want to understand your body composition, specifically how much of your weight is fat, muscle and bone, then the DEXA + RMR bundle gives you both in a single session at Evolve Fitness, Timperley. Most clients focused on body recomposition, weight management or metabolic health book both, because knowing your calorie burn without knowing your body composition gives you half the picture.
RMR is relatively stable over time. Most clients retest every 6 to 12 months, or when something significant changes: a major shift in weight, a meaningful change in training volume, starting or stopping medication, or a hormonal transition such as perimenopause. Clients managing weight or fuelling across an Altrincham 10K or Manchester Marathon season often retest at the start of each main training block.
Yes, particularly for athletes in high-volume training. RMR gives you the calorie floor, the minimum intake required to maintain basic physiological function. Athletes who underfuel relative to training load commonly experience suppressed performance, slower recovery, increased injury risk and, over time, hormonal disruption. Knowing your RMR and applying an accurate total energy expenditure multiplier means you can fuel your training properly rather than by feel or generic online estimates.
No. They measure completely different things. A DEXA scan measures what your body is made of: fat mass, lean mass and bone mineral density. An RMR test measures how much energy your body burns at rest. They complement each other well, which is why the DEXA + RMR bundle is our most popular option. DEXA tells you your body composition; RMR tells you your calorie baseline. Together they give you the two numbers most nutrition plans need but rarely start from.
The respiratory exchange ratio is the ratio of CO2 you produce to O2 you consume. At rest, an RER near 0.7 indicates predominantly fat burning; near 1.0 indicates predominantly carbohydrate burning. Most people fall between 0.75 and 0.90 at rest. A high resting RER can reflect high carbohydrate intake in the hours before the test (which is why fasting matters), chronic stress, or a metabolic state where the body struggles to access fat stores efficiently. Your report includes your RER with a plain-English interpretation.
