RQ resting metabolic rate test · St. Louis

RQ Resting Metabolic Rate Test

The RQ test measures, from your breath, how your body uses fuel while it rests. You sit quietly and breathe as usual through a mouthpiece or a mask, and the numbers guide your diet and metabolic health coaching.

Measura RQ assessment

You get this test only if your physician orders it. Our staff books it and keeps following up, visit after visit, until the result is in your chart.

What is RQ?

You sit still for a short time and breathe in your normal rhythm through a mouthpiece or mask.

Why would your physician order it?

The readout gives the calories you burn at rest and how much of that fuel comes from sugar versus fat. That gives the eating plan we coach at your visits its starting point.

What does the test feel like?

Quiet, relaxed breathing. No needles.

How do you get ready?

Starting about 4 hours ahead: nothing to eat, no workout, and no caffeine or nicotine.

What should you tell us first?

Let us know before the test if any of these apply to you:

  • You struggle to breathe through a mouthpiece

How long does it take?

15 to 20 minutes.

What to remember

  1. For the 4 or so hours before your test: skip food, workouts, caffeine and nicotine.
  2. It reveals your body’s fuel mix at rest.
  3. Your results shape your eating plan.

Show us you have it: Name the time on test day when you will cut off food, exercise and coffee. If any part is unclear, ask us to go over it again; there is no limit on that.

Your results feed straight into diet and metabolic health coaching and our broader metabolic care.
