RMR testing in Roseville, MN — the facts
- What it is: a measured resting metabolic rate — the calories your body uses at rest — by indirect calorimetry. Measured, not estimated from a population formula. The measurement is taken under standardized resting conditions, and your result reflects that test.
- Price: $165.
- Device: Breezing Med, FDA-cleared. It measures both oxygen consumption and carbon dioxide production. Measuring both gases is what makes a respiratory quotient (RQ) possible — your resting fuel-mix reading. A device that measures oxygen alone has to assume a fuel mix rather than measure it.
- Appointment: 30 minutes. The test itself takes about 20 — roughly 10 minutes of preparation and rest, then about 10 minutes of relaxed breathing through a clean, single-use mask.
- Preparation: no food, caffeine or exercise within four hours. No alcohol the day before. No nicotine before the test. Hydrate normally.
- What you get: your measured resting energy expenditure, your resting RQ, a generated findings report to take home, and a brief walkthrough with Dr Jared (about 5–10 minutes).
- What one reading does not establish: a single resting RQ does not establish metabolic flexibility, and one result does not identify a cause on its own.
- Access: open to the public. No referral required. Book online.
- Where: Rosedale Tower, 1700 West Highway 36, Suite #400, Roseville, MN 55113.
- Also available: the $195 Comprehensive Metabolic Assessment adds an InBody 580 scan, blood pressure, grip strength and height, with an integrated read across all measures and a designed 2–3 page report, in one 40-minute visit.

Here for something specific?
What is resting metabolic rate?
Your resting metabolic rate (RMR) is the number of calories your body burns just to keep you alive — heart beating, lungs working, brain running — before you’ve moved a muscle. For most people it’s 60–75% of everything they burn in a day. It is, by far, the biggest line item in your metabolism.
Think of it as your engine at idle. People of similar size and age can have different measured resting metabolic rates. That difference can matter for nutrition planning, but it is only one factor alongside food intake, activity, body composition, sleep, medications and health conditions.
Think of your body like a hybrid vehicle. Fat is like the electric system—well suited to lower-demand cruising. Carbohydrate is like the gas engine—available when energy demand rises. At rest, your body generally uses a mixture of both.
RQ is like a dashboard reading taken while the vehicle is idling. It tells us which fuel contributed more during the test. It does not tell us from one resting measurement how well your body switches between fuels when activity, food intake or other conditions change.
Online calorie targets usually begin with population equations. Measuring RMR gives you a person-specific resting value to use alongside activity, food intake, body composition and progress over time. It reduces one source of uncertainty; it does not determine total daily needs or explain weight change by itself.
A formula estimates. Indirect calorimetry measures.
Many calculators and consumer devices estimate resting metabolism from formulas. Breezing Med measures gas exchange directly.
RMR (resting metabolic rate): the energy your body uses at rest to support breathing, circulation, temperature regulation, brain activity and other basic functions.
What you can do once you know your measured RMR.
RQ — your resting fuel mix
RQ is the dashboard reading at idle. Metabolic flexibility is how well the system shifts fuel use when conditions and demands change.
Eating decisions, grounded in data.
Your measured RMR provides one concrete input for nutrition planning. It should be interpreted alongside food intake, activity, body composition and progress over time.
Whether your engine matches your body.
A measured RMR that differs substantially from the predicted value is a finding to put in context. Body composition, recent intake, sleep, recovery, medications and health conditions may affect the result, but the RMR test does not identify a specific cause by itself.
A baseline to retest against.
Retesting can show whether your measured RMR and resting fuel use changed over time, giving you another data point to compare with your nutrition, activity and body-composition progress.
What it’s like.
Plan for a 30-minute appointment. The testing sequence takes about 20 minutes: approximately 10 minutes for preparation and rest, followed by approximately 10 minutes of relaxed breathing. A brief clinician walkthrough follows.
Arrive rested.
No food, caffeine, or exercise within four hours of your visit. No alcohol the day before. No nicotine before the test. Hydrate normally and wear something comfortable.
Sit down and breathe.
You sit in a comfortable chair. We place a clean, single-use mask over your nose and mouth. You breathe normally for about 10 minutes. No talking, no movement.
The device reads your gas exchange.
The Breezing Med measures how much oxygen you’re consuming and how much carbon dioxide you’re producing. That ratio plus the rate is the science behind your RMR — it’s called indirect calorimetry, and it’s the clinical standard.
Brief clinician walkthrough.
Once your number is calculated, Dr Jared Larsen (LN, CNS, DC, MS) walks you through what it means. About 5-10 minutes.
What patients say.
He can look at the ranges within the normal ranges and help you understand how YOUR body is working.
“Jared’s knowledge is mind-blowing and he isn’t trying to sell you on any cookie-cutter products or packages or workout routines, he is helping you understand how YOUR body works… A test result may look normal to your normal doctor, but Jared can look at the ranges within the normal ranges and help you understand how YOUR body is working.”

I was so sick of the traditional system — Dr Jared offers tests other offices don’t.
“Dr Jared is great. If you’ve been struggling and need answers and a Dr. that listens, this is the place for you. I was so sick of the traditional system, I want getting help or answers. I also was really interested in getting a Dutch test, which other dr offices won’t offer and Dr Jared does. Along with other valuable tests.”

Individual results vary.
RMR alone, or bundle with InBody?
Two valid choices. Here’s the side-by-side.
| InBody alone | RMR alone | The CMA | |
|---|---|---|---|
| Body composition (fat, muscle, water) | ✓ | — | ✓ |
| Resting metabolic rate | — | ✓ | ✓ |
| Brief Dr Jared walkthrough | — | ✓ | ✓ |
| Designed written report | — | — | ✓ |
| Time in clinic | ~30 sec | ~30 min | ~40 min |
| Cost | $45 | $165 | $195 |
For $30 more than the RMR alone — and $15 less than booking the InBody and RMR separately — the CMA adds InBody testing, blood pressure, grip strength, height, an integrated read across all measurements and a designed 2–3 page report. Choose RMR alone when you only want the resting-metabolism measurement; choose the CMA when you want the combined baseline.

Things people ask.
Do I need to be a patient at TCM?
No. The RMR is open to the public.
How should I prepare?
No food, caffeine, or exercise within four hours of your visit. No alcohol the day before. No nicotine before the test. Hydrate normally and wear something comfortable.
Is this safe during pregnancy?
The test itself is non-invasive and generally considered safe, but interpretation during pregnancy is different. If you’re pregnant, we’d recommend starting with a quick conversation to discuss whether the timing makes sense.
How accurate is the Breezing Med?
Indirect calorimetry as a method is the standard for measuring RMR. Breezing brings that capability into an outpatient clinic.
Is this different from what my watch or smart scale says?
Yes. Watches and fitness trackers estimate calories burned from population formulas and your heart rate, and smart scales estimate a BMR from a body-composition equation — both are useful, but they are educated guesses. The Breezing Med measures your actual resting metabolic rate directly, from the oxygen and carbon dioxide in your breath. Think of it as comparing device estimates with a measured resting value.
How often should I retest?
Most people retest annually when maintaining, or every 3–6 months when actively making a defined nutrition, training, or body-composition change. The timing should match what you are trying to evaluate.
Can I just get a printout, or is there a designed report?
The standalone RMR includes your device result, a generated findings report, and a brief walkthrough with Dr Jared. The $195 Comprehensive Metabolic Assessment adds InBody testing, blood pressure, grip strength, height, an integrated clinician read across all measurements, and the designed 2–3 page report.
What if my number is really low or really high?
That can be useful information. A result at either end may reflect several factors, so Dr Jared will put the number in context, explain what it may indicate, and discuss practical next steps.
