Methods for data analysis of resting energy expenditure measured using indirect calorimetry

Indirect calorimetry (IC) is the most commonly used method to measure energy expenditure in the research setting to evaluate resting and physical activity energy expenditure, and support understanding of energy homeostasis, i.e., mechanisms that regulate weight-loss or weight gain [1]. Despite resting energy expenditure (REE) representing between 60% and 70% of daily energy expenditure [1], IC measurements usually last between 30 and 60 minutes to estimate the daily REE [2], using volume of oxygen consumption (VO2) and volume of carbon dioxide production (VCO2) equations [3].
