RMR - DexaFit Greenville
The RMR Canopy Difference
The most comfortable & accurate way to measure your metabolism.
Our RMR metabolism assessment uses the Italian-made COSMED Q-NRG-Max with a ventilated canopy hood — a clear, lightweight dome (pictured below in our office) that rests over your head while you relax. There's no mask sealed to your face and no clip pinching your nose, so you can breathe completely normally and simply lie back for the duration of the test.
That relaxed, undisturbed state matters. Because resting metabolic rate measures your body at true rest, anything that makes you tense or breathe differently — like a tube and a pinched nose — can skew the numbers. The canopy removes those variables entirely, which is why it's the mode validated against laboratory gold-standard methods and recommended for the most accurate readings. The result is a more comfortable experience and a more reliable measurement of exactly how many calories your body burns at rest.
What to expect
Each patient gets a clean canopy and a brand-new, medical-grade air filter. The lights are dimmed, a calming weighted blanket is placed over you, and you listen to relaxing spa music for about 15 minutes while the metabolic cart measures the oxygen you breathe in and the carbon dioxide you breathe out.
What you'll discover about your body:
Your true calorie baseline — precisely how many calories your body burns at rest
Your fat-loss target — the calorie range you need to lose body fat, built on your real numbers instead of a generic formula
Your muscle-gain target — the surplus you need to build lean muscle
Your metabolic speed — how you actually compare to peers your age and sex (do you really have a "slow" metabolism, or is something else going on?)
Your fuel mix — whether you're burning more fat or carbohydrates at rest, a valuable window into your metabolic health
Stop guessing about your metabolism. Measure it.
How fast is your metabolism, really? Are you burning fat or carbohydrates at rest? Most people never actually know—they rely on generic online calculators and end up under- or overeating without realizing it.
A Resting Metabolic Rate (RMR) assessment is the most accurate way to measure your true metabolism. Using medical-grade indirect calorimetry, it precisely calculates how many calories your body burns at rest—simply lying back and breathing—and reveals whether your metabolic rate is fast, slow, or average compared to others your age and size.
Once you know your exact calorie burn, you can stop guessing and start fueling with precision—eating the right amount to lose fat, build muscle, or maintain, based on your body instead of a formula.
For best results, we highly recommend overnight fasting prior to your RMR assessment. Please review all pre-test protocols.
Understand Your Metabolism in Action
Your body burns calories even at rest—but how many, and from which fuel sources? An RMR (Resting Metabolic Rate) test reveals how your metabolism is functioning, including whether your body is using more fat or carbohydrates for energy.
This matters for longevity. Efficient fat-burning at rest is often linked to stronger metabolic health and better mitochondrial function—the systems that power your energy, recovery, and long-term vitality. With accurate RMR data, you can build nutrition and training strategies that support fat loss, preserve lean muscle, improve metabolic flexibility, and help you feel stronger and more energized as you age.

FAQs
-
RMR testing measures your Resting Metabolic Rate, akin to gauging the energy needed to keep a car idling.
It tells us how many calories you burn at rest, supporting vital functions like breathing, circulating blood, and cellular repair.
It's a fundamental indicator of your metabolic health, crucial for understanding how your body uses energy when it's not active.
-
Your RMR accounts for about 70% of your Total Daily Energy Expenditure (TDEE). Knowing it is essential for accurately gauging your daily calorie needs.
This information is critical whether you're aiming to lose weight, build muscle, or maintain your current state. It's the foundational number on which your nutrition and fitness plans should be built.
-
The test highlights how your body primarily uses energy - whether it's burning fats or carbohydrates.
This insight allows you to tailor your diet to your metabolic strengths, optimizing the way you fuel your body for daily activities and workouts.
-
Similar to prepping for a medical procedure, fasting for a minimum of five hours and limiting physical activity helps ensure your body is in a true resting state. Avoid caffeine and stimulants to prevent any alterations in your metabolic rate.
-
RMR includes calories burned during low-effort activities, making it a more realistic measure of your daily caloric needs, while BMR is the bare minimum your body needs to function at rest.
Think of RMR as the energy needed to power not just the engine but also the lights and radio of a car, compared to just the engine (BMR).
-
DexaFit's RMR test is significantly more accurate than formula-based estimates, which can be off by 30-40%. It's like using a high-precision measuring tool versus a rough estimate, ensuring you get an accurate understanding of your metabolic health.
-
Absolutely. By understanding your RMR, you can more effectively tailor your diet and exercise plans. It's a critical component in breaking through weight loss plateaus or efficiently building lean mass.
-
Embarking on an RMR test is like decoding your body's energy playbook. It reveals your Resting Metabolic Rate, the baseline energy your body uses for essential functions like breathing and circulating blood. But there's more – you'll also discover your Respiratory Exchange Ratio (RER), which tells you whether fats or carbs are your body's preferred fuel.
Your Resting Heart Rate (RHR) unfolds the tale of your heart's efficiency, a silent yet vital aspect of overall health.
Diving deeper, the test sheds light on your Total Daily Energy Expenditure (TDEE) – a comprehensive measure encompassing not just your RMR, but also the energy expended through physical activity and workouts.
TDEE even factors in the subtle yet significant energy used in everyday non-exercise movements, known as Non-Exercise Activity Thermogenesis (NEAT). NEAT includes all the small activities you do throughout the day – walking, typing, even fidgeting – that collectively contribute to your daily calorie burn.
Understanding TDEE is crucial, as it represents the total number of calories you expend daily, guiding you to make informed decisions about your diet and exercise for optimal health and wellness.
-
Lifestyle changes such as interval training can significantly boost your RMR. This type of training prevents your body from becoming too efficient at one exercise, continuously burning peak calories.
Dietary adjustments like increasing protein intake also play a role, as protein requires more energy to digest.
-
Several variables influence your metabolic rate, including age, muscle mass, hormonal balance, and overall health. Understanding these factors is key to making informed decisions about your nutrition and exercise, optimizing your metabolic efficiency.
-
A "normal" RMR can vary greatly from person to person depending on age, gender, and body composition. It's essential to understand your individual RMR and work towards optimizing it for your specific goals and needs.
This is where an RMR test comes in handy as it provides a personalized baseline measurement of your metabolic rate. From there, you can make targeted changes to improve or maintain your RMR for optimal health and longevity.
