Metabolic testing measures your Resting Metabolic Rate—the exact number of calories your body burns at rest just to maintain basic functions like breathing, circulation, and cell production. This number forms the foundation of effective nutrition planning.

Why does this matter? Most people estimate their calorie needs using generic formulas or online calculators. These estimates can be off by 300-500 calories per day, which completely sabotages fat loss and muscle gain goals. Your actual metabolism is unique based on your age, sex, genetics, muscle mass, hormonal status, and training history.

XGYM uses an indirect calorimetry metabolic analyzer that measures the oxygen you consume and carbon dioxide you produce. This shows exactly how many calories your body burns at rest—providing the precise starting point for your nutrition strategy. Combined with your activity level and training, we calculate your total daily energy expenditure (TDEE) and design macronutrient targets specifically for your goals.
