Data are presented as mean ± SD. Differences between groups were assessed by means of Mann-Whitney U tests, and the corresponding P values are shown in the table. Different changes from baseline to respiration chamber between groups were assessed by means of analysis of covariance, with baseline values as covariate; there were no significantly different changes between the groups.
Abbreviations: BMI, body mass index; EB, energy balance; EI, energy intake; F, female; HOMA-IR, homeostatic model assessment of insulin resistance; HP, high protein; M, male; MP, moderate protein; ; RQ, respiratory quotient; TEE, total energy expenditure.
