RMR Metabolism Test in Phoenix, Arizona
The calorie target your plan keeps guessing at.
Your body burns energy around the clock, even when you are doing nothing at all. A Resting Metabolic Rate (RMR) test at DexaFit Phoenix measures the calories your body truly needs just to keep running, so your nutrition, fat loss, and training rest on a measured figure rather than a rough estimate.
With that number in hand, you can line up your eating and your workouts behind it: build lean muscle, drop the fat you want gone, and steer your health where you want it to go.

See How Your Body Burns
No two metabolisms run the same. Yours moves with your muscle, your routine, and the way you live across the week. An RMR test at DexaFit Phoenix measures the calories you spend at rest and shows whether your body is reaching for fat or carbohydrate as its fuel.
With that read, you can tune your food and your training to how your own body runs, instead of a generic chart built for an average that is not you.

What does an RMR test measure, and what happens during it?
An RMR test reads your Resting Metabolic Rate, the energy your body uses to run the background work of staying alive, like breathing, circulation, and repairing tissue. You sit relaxed and breathe normally into a mask while the system measures your energy use through breath analysis. The result is a direct read on how your body burns energy at rest.
What makes my RMR number useful?
Resting metabolism makes up close to 70% of the energy you use over a day. Once you know that figure, your calorie targets have a measured anchor, whether you're after fat loss, muscle gain, or staying right where you are. It's the base layer your nutrition plan should sit on.
How do I prepare for the test?
Skip food for at least five hours, keep activity light on your way in, and avoid caffeine and other stimulants so your body can settle into a true resting state before we measure it.
RMR versus BMR, what is the difference?
BMR is the absolute minimum your body burns at complete rest. RMR adds the light, ordinary activity of a normal day on top of that, which makes it a closer match to the calories your real day actually calls for.
Is a measured RMR worth more than an online calculator?
Considerably. Formula and app estimates can be off by 20 to 30%. Measuring your metabolism directly through your breath replaces that range with a number drawn from your own body.
What results do I take home?
Your Resting Metabolic Rate, your Respiratory Exchange Ratio (whether your body is leaning on fat or carbohydrate for fuel), your resting heart rate, and your Total Daily Energy Expenditure, which combines your RMR with the energy spent on movement and daily life.
Can I raise my RMR over time?
You can. Building muscle, training in intervals, and getting more protein all nudge it upward, since muscle tissue and digesting protein both demand more energy. Retesting later shows whether those changes moved the number.
Available at our Tempe, Gilbert, and North Phoenix locations.
