What Metabolic Analysis Reveals

Physician-led breath analysis measures oxygen use and carbon dioxide production to assess aerobic fitness, energy expenditure, fat and carbohydrate use, breathing efficiency, and exercise thresholds. Results help guide nutrition, training, recovery, and progress tracking. Testing is available to members and non-members.

Aerobic Fitness

VO2 Max & Longevity

Understand how precise measurement of oxygen consumption provides a benchmark for cardiovascular health and overall vitality.

Metabolism

Science of Fuel Utilization

Explore metabolic flexibility—how your body switches between fats and carbohydrates as fuel intensities change during exercise.

Nutrition

Basal Metabolic Rate

Learn how indirect calorimetry identifies your daily caloric needs, forming the foundation of a data-driven nutritional plan.

What to Expect on Test Day

Resting Metabolic Rate (RMR)
  • Measurement takes approximately 15 minutes.

  • Rest on our recliner and breathe normally through the fitted breath-analysis mask.

  • Remain still and relaxed; avoid talking or fidgeting.

  • Allow another 10–15 minutes to review your results.

Active Metabolic Rate / VO₂ Max
  • Testing takes approximately 20 minutes, including warm-up and cool-down.

  • Use both arms and legs on the Rogue Echo air-resistance bike.

  • Warm up gently for 3–5 minutes, then follow guided increases in effort each minute.

  • Testing is supervised and individualized. You may stop at any time; we may also stop for fatigue, symptoms, or clinical considerations.

  • Cool down with 2–3 minutes of light pedaling while recovery is recorded.

  • Allow another 10–15 minutes to review your results.

Exercise testing may require medical clearance. This is a non-diagnostic metabolic performance assessment, not a medical CPET.

How to Prepare for Testing

Good preparation helps reduce variables that can affect measurement accuracy, so your results reflect your body as clearly as possible.

For All Tests

• Arrive well hydrated.
• Wear comfortable clothing.
• Remain calm before testing; stress or an elevated heart rate can influence measurements.

Before AMR / VO₂ Max Testing

• Avoid strenuous exercise for 24 hours.
• Avoid a large meal for 2–3 hours before testing.
• Limit caffeine for 4 hours.
• Wear athletic clothing appropriate for cycling.

Before RMR Testing

• Avoid high-fat meals within 4 hours.
• Fast approximately 4 hours, but no more than 12 hours.
• Water is permitted.
• Avoid coffee, tea, and caloric beverages for 4–6 hours.
• Avoid exercise for 24 hours.
• Avoid alcohol for 12 hours.
• Avoid cold plunges or saunas within 4 hours.

Additional Insights from Metabolic Testing

Your resting or exercise test can provide the insights below. Available measures depend on your testing protocol.

VO₂ Max & Aerobic Fitness

Measures aerobic fitness and how your body responds as exercise intensity increases.

Resting Energy Needs (RMR)

Measures energy used at rest to help guide nutrition and calorie planning.

Fat & Carbohydrate Use

Shows how your body uses fat and carbohydrates as fuel at different exercise intensities.

Training Zones (VT1/VT2)

Identifies breathing thresholds to help personalize your training zones.

Your Personalized Insights

PNOĒ assesses up to 23 metabolic and cardiorespiratory biomarkers. Dr. DeVito interprets relevant findings with your history and goals to guide training, nutrition, and recovery. Testing does not diagnose disease or replace medical care.

Your Results & Sample Reports

Metabolic testing is available to everyone—members and non-members. The testing helps assess aerobic fitness, breathing efficiency, energy expenditure, fuel use, and exercise thresholds.

PNOĒ breath analysis can report up to 23 metabolic and cardiorespiratory biomarkers, depending on the testing protocol. Results may include VO₂ max, ventilatory thresholds, resting and active metabolic rate, and fat and carbohydrate use.

See examples of the reports you receive after testing. Dr. DeVito reviews your results in the context of your health history and goals. The measurements available depend on the resting or exercise protocol performed.

Body Composition Testing

Advanced Body Composition Testing

Rather than relying solely on Body Mass Index (BMI), which has important limitations, we utilize the advanced InBody 570 Body Composition Analyzer to provide a more detailed and meaningful assessment of physical health.

This technology helps us better evaluate progress and make more precise adjustments to nutrition, exercise, and wellness plans.

What the InBody 570 Measures

  • Lean muscle mass, including each arm, leg, and torso segment
  • Body fat percentage and total fat mass
  • Total body water, including intracellular and extracellular water
  • Indicators that may help assess fluid retention, inflammation, or cellular health trends
  • Visceral fat (fat surrounding internal organs)
  • Estimated basal metabolic rate (daily caloric needs at rest)

Why It Matters

With repeat testing over time, we can monitor meaningful changes in body composition rather than relying only on body weight or BMI.

This allows for a more accurate and individualized approach to:

  • Weight management
  • Muscle gain / preservation
  • Metabolic health
  • Nutrition strategies
  • Exercise planning
  • Long-term wellness tracking

Trusted Technology

InBody analyzers are used by leading health systems, performance centers, and professional organizations, including institutions such as Mayo Clinic, Cleveland Clinic, Johns Hopkins, and many professional sports teams.

Quick, Non-Invasive, and Convenient

The test is painless, non-invasive, and typically takes less than one minute to complete.


A few simple preparation steps are recommended beforehand to optimize accuracy, and these guidelines can be reviewed prior to your appointment.
