The Problem: Guessing Your Way to Health
When it comes to fat loss, energy, performance, and metabolic health, most people are operating in the dark — trying diets and “best practices” without knowing how their body actually burns fuel. You may follow every program by the book yet plateau, stall, or feel worse because your metabolic “machinery” is misaligned.
What if you could see inside your metabolism, run diagnostics on your energy systems, and get a map for precisely how your body uses oxygen, burns fat, or resorts to carbohydrates? That’s where the PNOĒ Metabolic Assessment changes everything.
What Is the PNOĒ Test?
The PNOĒ test is a clinical-grade breath-analysis system that measures how your body uses oxygen (VO₂) and produces carbon dioxide (VCO₂). With these data, it calculates dozens of biomarkers — from your resting metabolic rate to active metabolic rate during exercise, your fat-burning efficiency, metabolic flexibility, and much more.
There are two primary modes:
- Resting Test (RMR / Resting Metabolic Rate): You breathe into the device while at rest. It reveals how many calories your body consumes at baseline, how efficiently you burn fat at rest, and your baseline metabolic health.
- Active / Exercise Test (AMR): You perform controlled exercise (usually on a bike or treadmill), while the PNOĒ monitors your oxygen and CO₂ dynamics under load. This reveals how your metabolism behaves under stress, your aerobic thresholds, fuel crossover points (when you shift from fat to carbs), mechanical efficiency, and maximum aerobic capacity.
These two tests together form your metabolic blueprint — a data-driven foundation for diet, training, and recovery strategies.
Sample Reports (For You to Preview)

These reports typically include charts and values like VO₂ max, fat burn efficiency, metabolic rate, and recommended zones or strategies based on your test.
The Science of Metabolic Testing
📊 VO₂ Max & Longevity
A JAMA 2018 study determined that VO₂ max is a stronger predictor of longevity than many traditional risk factors (blood pressure, cholesterol, smoking) — in other words, how effectively your body uses oxygen may matter more than many lab values when it comes to lifespan.
📊 Metabolic Flexibility
Metabolic flexibility is your body’s ability to switch between burning fats and carbohydrates. Poor flexibility is tied to insulin resistance, metabolic syndrome, and chronic fatigue (Cell Metabolism, 2017). PNOĒ detects this imbalance, enabling targeted interventions.
📊 Resting Metabolic Rate Accuracy
Indirect calorimetry (the same principle used by PNOĒ) is considered a gold standard method for measuring resting energy expenditure — far more accurate than predictive equations.
📊 Exercise Efficiency & Recovery
The AMR test reveals mechanical efficiency — how much energy you waste vs. how much you convert to motion. More efficient athletes recover faster and perform better.
Conditions & Goals That PNOĒ Supports
- Weight-loss resistance / metabolic plateau
- Chronic fatigue & low energy
- Insulin resistance, prediabetes, or metabolic syndrome
- Cardio fitness optimization
- Endurance athletes & performance coaching
- Longevity and preventative health
What to Expect During a Test
- Duration: The resting test takes roughly 10–15 minutes; the active test adds ~15–20 minutes depending on protocol.
- Procedure: In the resting test, you breathe quietly through a mask. In the active test, you exercise (usually on a bike) through several intensity stages while PNOĒ captures breath-by-breath data.
- Output: After your session, you’ll receive a comprehensive report (usually within 24–48 hours) with graphs, metrics, zones, and clear recommendations tailored to your physiology.
Why GrassRoots Uses PNOĒ
We believe in precision, not guesswork. At GrassRoots, we don’t “prescribe by default” — we test first, then tailor nutrition, exercise, and recovery plans based on your unique metabolic profile.
We integrate PNOĒ with our other Peak State modalities. For example:
- Use RMR data to set your dietary baseline before applying IR sauna, HBOT, or cold protocols.
- Use AMR and VO₂ data to fine-tune training zones, then deliver oxygen, red light, or PEMF at the right times.
- Retest every 3–6 months to measure progress and refine protocols.
Take Action
Stop guessing what’s best for your body. With PNOĒ, you’ll have clarity — a true, actionable metabolic roadmap.
