Indirect Calorimetry Metabolic Endpoints


  • Basal energy expenditure (EE) or resting EE (REE) is the energy to sustain the basic life functions at rest.

  • Diet-induced thermogenesis is the energy used during metabolism postprandial.

  • Activity energy expenditure (AEE) is the energy consumed by physical activity.
  • Substrate oxidation and respiratory quotient (RQ) is the ratio of carbon dioxide produced for amount of oxygen consumed.
