Breezing Pro®

The World’s Only Professional & Personal Wearable Metabolism Tracker


Breezing Pro is a portable, clinically validated indirect calorimeter that accurately measures metabolism using gold-standard technology—bringing laboratory-level metabolic testing into clinics, fitness centers, and everyday health management.

Unlike traditional wearables that estimate calories, Breezing Pro measures real energy expenditure, enabling precise nutrition, fitness, and weight-management decisions.


Clinically Proven Metabolic Measurement

Breezing Pro uses gold-standard indirect calorimetry, the scientific method recommended by leading professional bodies for accurate metabolic assessment.


Why Indirect Calorimetry Matters

  • Measures actual energy expenditure, not predictions

  • Recommended by the Academy of Nutrition and Dietetics and the American College of Sports Medicine

  • Validated against:
    Douglas Bag method (gold standard)
    FDA-cleared metabolic carts

  • Published accuracy in peer-reviewed scientific studies

What Breezing Pro Measures

Breezing Pro delivers comprehensive metabolic insights in just 10 minutes:

  • Resting Energy Expenditure (REE) – Calories/day

  • Total Energy Expenditure (TEE) – Calories/day

  • VO₂ – Oxygen consumption (ml/min)

  • VCO₂ – Carbon dioxide production (ml/min)

  • Respiratory Quotient (RQ)

  • Fat & Carbohydrate Burn Ratio

  • Exhalation Rate (ml/min)

  • Breath Frequency (/min)

  • Total Volume (ml)

RQ analysis reveals whether your body is burning fats or carbohydrates, enabling highly personalized nutrition and exercise plans.
