Assessment of under- and over-reporting of energy intake
Using the ratio of energy intake to resting metabolic rate (RMR) assessed under- and over-reporting of energy intake. RMR measured by indirect calorimetry (MetaLyzer 3B, Cortex, Leipzig, Germany). To assess the validity of the reported energy intake, we used the ratio of the energy intake to RMR. We used the values defined in the Black et al. and Goldberg et al. (14, 15) study to investigate the relative degree of under- and over-reporting. Thus, the range of 1.35-2.39 identified as the normal report energy intake in this study.
