Understanding your metabolism is key to designing effective nutrition and lifestyle strategies. We use indirect calorimetry, the gold-standard method for assessing energy metabolism, to measure your Resting Metabolic Rate (RMR) with precision.
Indirect calorimetry estimates your energy expenditure by measuring the exchange of gases during breathing - specifically, oxygen consumption (VO₂) and carbon dioxide production (VCO₂).
Testing is simple, non-invasive, and involves wearing a lightweight face mask with integrated advanced flow meters and gas sensors.
The Calibre Biometrics device we use utilises state-of-the-art wearable technology validated for accuracy against 15 leading metabolic analysers in a recent independent study. The Calibre device demonstrated excellent agreement in measuring oxygen uptake, carbon dioxide output, and total energy expenditure, achieving one of the lowest error rates among tested systems.
Accurate knowledge of your resting energy needs is the foundation of effective weight management. Many weight-loss challenges stem from misestimating calorie requirements. Generic formulas often over- or underestimate energy needs by up to 30%, leading to frustration, plateaus, or unsafe deficits.
By measuring your RMR directly:
Research also shows that individuals are more likely to follow dietary recommendations when they are informed by objective metabolic testing, helping to bridge the gap between theory and practice.
Matching energy intake to energy expenditure is crucial not only for weight control, but also for long-term health, recovery, and performance.
