PNOE Testing is a clinical grade metabolic and cardiorespiratory assessment. You wear a lightweight mask connected to an analyzer that measures the oxygen you take in and the carbon dioxide you breathe out. From that breath data, it reveals how many calories you burn, whether you rely more on fat or carbohydrate for fuel, and your fitness baseline.
The results support weight management, athletic training and longevity planning, replacing generic calorie formulas with numbers from your own body. At our Merrick clinic, your provider walks you through each metric, then translates it into practical nutrition, exercise and recovery guidance, and can retest later to show how your metabolism and fitness respond to the plan.

Questions About PNOE Testing
What does PNOE measure?
PNOE analyzes the gases in your breath to estimate resting calorie burn, the balance of fat and carbohydrate you use for fuel, breathing efficiency and cardiorespiratory fitness. Together these create a picture of your metabolic health that generic formulas cannot provide.
How should I prepare for my test?
Your provider will give specific instructions, which commonly include avoiding food, caffeine and intense exercise for a set period beforehand. Wear comfortable clothing and athletic shoes in case an exercise portion is part of your test, and arrive well rested.
Is PNOE useful for weight loss?
Yes, it is often used to personalize weight management. Knowing your actual calorie burn and how you use fuel helps set realistic nutrition targets and exercise intensity. It can also complement a medical weight loss program by showing how your metabolism responds over time.
How often should I retest?
Many people retest after a few months of following their plan to see how metabolism and fitness have changed. Athletes may test around training cycles. Your provider will suggest timing that fits your goals and the changes you are making.
What to Expect
Your provider explains how to prepare, which may include arriving rested and skipping food, caffeine or hard exercise beforehand. During the test, you wear the mask while breathing at rest and, depending on your plan, during a guided exercise effort, with the analyzer recording each breath. The test is noninvasive and you can pause at any time. Afterward, you review your metabolic and fitness profile together and leave with clear next steps.
