What is resting metabolic rate?
Resting metabolic rate (RMR) is the number of calories the body burns at rest in a 24-hour period to maintain essential functions including breathing, circulation, brain activity, and organ function. It accounts for approximately 60-75% of total daily energy expenditure in sedentary and moderately-active adults — the foundation of any sustainable calorie-balance approach. RMR can be estimated from age, weight, height, and sex using equations such as Mifflin-St Jeor or Harris-Benedict, but estimates are unreliable in individuals with non-average muscle mass, suppressed metabolism from prior dieting, undertreated hypothyroidism, or altered body composition. Twin Cities Metabolism measures RMR directly using Breezing Med indirect calorimetry (FDA-cleared), which calculates RMR from measured oxygen consumption and carbon dioxide production — the same method used in research and clinical settings including the Mayo Clinic.
Your metabolic engine, in actual numbers.
Resting Metabolic Rate is how many calories your body burns at rest — keeping your heart beating, your brain running, your organs working. It’s the foundation of your daily calorie burn.
Most people use an online calculator to estimate their RMR. Those calculators are wrong for almost everyone — they assume “average” muscle mass, “average” thyroid function, “average” recovery. If anything about you isn’t average — and that’s most of us — the estimate misses.
The Breezing Med doesn’t estimate. It measures. You breathe through a single-use mask, the device reads your oxygen consumption and carbon dioxide production, and the math gives us a number that’s accurate within a few percent. The same indirect-calorimetry technology used at Mayo Clinic.
What you can do once you know your real RMR.
Eating decisions, grounded in data.
If you’ve been eating “less” without losing weight, your RMR will tell us whether your metabolism slowed down — or whether the deficit was never there in the first place. Different problems, different fixes.
Whether your engine matches your body.
A low RMR for your size suggests something is suppressing your metabolic rate — thyroid, undereating history, sleep, recovery, or several. Identifying it is half the work.
A baseline to retest against.
Six months from now, you can do another RMR and see exactly what shifted. Real data on whether what you’re doing is working — not guesses based on the scale.
What it’s actually like.
About 15 minutes from check-in to walking out. No needles, no fasting drinks.
Arrive rested.
No food, caffeine, or vigorous exercise for at least 3-4 hours before. Hydrate normally. 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 walks you through what it means. About 5-10 minutes.
Who this is for.
- ✓ You’ve been eating less but not losing weight — and want to know if your metabolism actually slowed
- ✓ You’ve been “trying everything” and want to start with the foundation
- ✓ You suspect a thyroid issue and want a metabolic-rate data point alongside lab work
- ✓ You’re an athlete or active person who wants to dial in fueling around your actual energy needs
- ✓ You’ve been told “your metabolism is broken” without anyone actually measuring it
- ✓ You’re curious how your RMR has changed since you were younger
- ✓ You’re considering the CMA but want to start with just one test
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 | ~5 min | ~25 min | ~45 min |
| Cost | $45 | $145 | $195 |
The CMA adds the InBody Scan and a written report for an extra $50. If you’re going to do the RMR anyway, the bundle is usually the better deal — but the RMR alone is a complete product.
$145. Test + brief walkthrough. No surprises.
INCLUDED
- ✓ Breezing Med RMR test (~20 min)
- ✓ Brief clinician walkthrough (~5-10 min)
- ✓ Printed RMR result you take home
- ✓ Clinician notes on what the number means
HSA / FSA: Typically eligible.
NOT INCLUDED
- · Body composition (add InBody → bundle as CMA for $195)
- · Designed written report (included in CMA)
- · Full lab workup (consider the Metabolic Blueprint)
- · Treatment program enrollment
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.”

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 vigorous exercise for at least 3-4 hours before. Hydrate normally. Wear something comfortable. Don’t smoke or use nicotine before the test.
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 free consult to discuss whether the timing makes sense.
How accurate is the Breezing Med?
Validated against FDA-cleared metabolic carts (the clinical gold standard) with high agreement. Indirect calorimetry as a method is the standard for measuring RMR. Breezing brings that capability into an outpatient clinic — it’s the same technology used at Mayo Clinic and Banner Health.
How often should I retest?
Most people retest annually if they’re maintaining, or every 3-6 months if they’re actively working through metabolic changes. Within the 6-month Reset program, RMR retesting is built into the protocol.
Can I just get a printout, or is there a designed report?
The standalone RMR comes with a printed result and notes from Dr Jared. If you want the full designed report (the kind you keep for years), that comes with the Comprehensive Metabolic Assessment — the $195 bundle that includes both your RMR and your InBody.
What if my number is really low or really high?
That’s exactly what we want to know. Both ends of the range have specific, treatable causes. Dr Jared walks through what your number means and what to think about next.
