Resting Energy Expenditure in Overweight and Obese Adults: Agreement Between Indirect Calorimetry and Prediction Formulas

An abstract of a study by Ziegler et al determining which predictive equations best agree with resting energy expenditure in healthy overweight and obese adults is presented. This study specifically identified the limits of agreement between (REE) using MedGem® and five predictive equations commonly used to calculate energy needs. Moreover, the study findings demonstrated the lack of of reliability of predictive equations in estimating caloric requirements in overweight and obese adults compared to indirect calorimetry. Furthermore, it is proposed that continued research is necessary to provide a simple and accurate calculation of energy needs for use in the overweight and obese population.
