Stop guessing your calorie needs: accurate RMR testing with COSMED technology

Published: 09 November 2026

How many calories do you really burn in a day? In this video, Jacob Zemer undergoes a Resting Metabolic Rate (RMR) test at Maze Medical Fitness, gaining a precise understanding of his body's daily energy expenditure.

By measuring the calories burned at rest, RMR testing provides the objective data needed to build effective nutrition and training plans based on physiology rather than estimates.

Through advanced breath-by-breath analysis of oxygen consumption (VO₂) and carbon dioxide production (VCO₂), the Quark CPET delivers highly accurate measurements of metabolic rate and energy expenditure. Knowing your actual RMR can help you:

Determine your true daily caloric needs
Create more effective weight loss strategies
Support muscle gain and body recomposition goals
Optimize training and recovery
Make informed decisions based on real physiological data

At COSMED, we believe that accurate measurement is the foundation of better health, fitness, and performance outcomes.
Whether you're an athlete, a healthcare professional, or someone looking to better understand your metabolism, metabolic testing provides valuable insights that can guide a personalized approach.
