metabolism measurement

Metabolism measurement assesses how efficiently your body uses energy. It typically involves measuring your resting metabolic rate (RMR), which is the number of calories your body needs to function while at rest—like breathing and maintaining body temperature. Methods include indirect calorimetry, where you breathe into a device that analyzes oxygen and carbon dioxide to estimate calorie burn. Understanding metabolism helps determine your daily energy needs and can guide nutrition and fitness plans. Factors like age, muscle mass, and activity level influence your metabolism, making personalized assessments valuable for health management.
