What is PNOĒ?

PNOĒ metabolic testing is a comprehensive medical-grade breath analysis that measures how efficiently your body uses oxygen and burns fuel, carbohydrates vs. fat, at rest and during exercise. It provides highly personalized data to optimize your fitness, nutrition, and overall metabolic health.

How It Works

During the assessment, you wear a specialized mask connected to a portable metabolic analyzer that tracks your breathing. It measures:

• Oxygen intake (VO2)
• Carbon dioxide output (VCO2)
• Airflow patterns

What It Measures

The test analyzes over 20 biomarkers to provide a deep dive into your physical health. The core metrics include:

  • VO2 Max: The maximum amount of oxygen your body can use during intense exercise, which is a key indicator of cardiovascular fitness and longevity.

  • Resting Metabolic Rate (RMR): The exact number of calories your body burns at rest, eliminating the guesswork from dieting and weight management.

  • Fuel Utilization: Tells you exactly when your body shifts from burning fat to burning carbohydrates, allowing you to train in the most effective heart rate zones for weight loss or endurance.

  • Cardiopulmonary Function: Evaluates how well your heart, lungs, and cellular system are performing under stress.

Who Is It For?

PNOĒ is utilized by elite athletes looking for a competitive edge, individuals trying to overcome weight loss plateaus, and people wanting to screen for metabolic disease risks. The data is used to build incredibly precise, customized nutrition and individual workout programs.
