Résumé
Optimal nutritional therapy, including the individually adapted provision of energy, is associated with better clinical outcomes. Indirect calorimetry is the best tool to measure and monitor energy expenditure and hence optimize the energy prescription. Similarly to other medical techniques, indications and contra-indications must be acknowledged to optimise the use of indirect calorimetry in clinical routine. Measurements should be repeated to enable adaptation to the clinical evolution, as energy expenditure may change substantially. This review aims at providing clinicians with the knowledge to routinely use indirect calorimetry and interpret the results. We performed a bibliographic research of publications referenced in PubMed using the following terms: "indirect calorimetry", "energy expenditure", "resting energy expenditure", "VCO We have gathered the knowledge required for routine use of indirect calorimetry in clinical practice and interpretation of the results. A few clinical cases illustrate the decision-making process around its application for prescription, and individual optimisation of nutritional therapy. We also describe the latest technical innovations and the results of tailoring nutrition therapy according to the measured energy expenditure in medico-economic benefits. The routine use of indirect calorimetry should be encouraged as a strategy to optimize nutrition care.

BACKGROUND AND AIMS
Optimal nutritional therapy, including the individually adapted provision of energy, is associated with better clinical outcomes. Indirect calorimetry is the best tool to measure and monitor energy expenditure and hence optimize the energy prescription. Similarly to other medical techniques, indications and contra-indications must be acknowledged to optimise the use of indirect calorimetry in clinical routine. Measurements should be repeated to enable adaptation to the clinical evolution, as energy expenditure may change substantially. This review aims at providing clinicians with the knowledge to routinely use indirect calorimetry and interpret the results.
METHOD
We performed a bibliographic research of publications referenced in PubMed using the following terms: "indirect calorimetry", "energy expenditure", "resting energy expenditure", "VCO
RESULTS
We have gathered the knowledge required for routine use of indirect calorimetry in clinical practice and interpretation of the results. A few clinical cases illustrate the decision-making process around its application for prescription, and individual optimisation of nutritional therapy. We also describe the latest technical innovations and the results of tailoring nutrition therapy according to the measured energy expenditure in medico-economic benefits.
CONCLUSION
The routine use of indirect calorimetry should be encouraged as a strategy to optimize nutrition care.

Déclaration de conflit d'intérêts
Conflicts of interest All the coauthors have contributed to the development and validation of the new indirect calorimeter (Q-NRG) in collaboration with the manufacturer, but independently in terms of financial support (see above). All coauthors have a major motivation to promote calorimetry for clinical and research activities as they consider IC has a corner stone for optimal nutrition, but they do not have commercial interest or receive personal benefits for this action.
