Energy expenditure, physical activity, and respiratory exchange ratio (RER) were measured by indirect calorimetry in C57BL/6J mice after 8 weeks of feeding respective diets. a Energy expenditure was calculated from measured VO2 and RER and is shown respective to BW for each treatment group. Night periods are represented by gray bars. b Average day and night energy expenditure values are shown for each treatment group. c Physical activity levels and RER (d) are shown as the average over a 3 days period. d Average day and night RER values are shown for each treatment group. All data are presented as mean ± SEM. Significant differences between groups by one-way ANOVA and post hoc Tukey are denoted by differing superscripts
