indirect calorimetry

Indirect calorimetry is a method used to measure how a person's body burns energy by analyzing the gases they breathe. It assesses oxygen consumption and carbon dioxide production to estimate the amount of calories the body uses at rest or during activity. This technique helps understand metabolic rate, providing valuable insights for nutrition, weight management, and medical assessment. Since it doesn't rely on invasive procedures, it offers a safe, accurate way to determine energy expenditure in various settings.
