Your resting metabolic rate (RMR) is the amount of energy your body uses at complete rest—the baseline that powers breathing, circulation, temperature regulation, and cellular repair. It makes up the foundation of your daily energy expenditure and is closely tied to body composition and overall metabolic health.

RMR testing measures how efficiently your body converts fuel into energy at rest. Understanding your true metabolic rate provides an objective baseline for nutrition planning, training, and long-term metabolic monitoring, replacing estimates with real measurement.

Paired with DEXA body composition analysis, RMR testing offers a complete picture of how your body is built and how it uses energy—supporting personalized, actionable recommendations for your long-term health.
