The LFD increased the energy expenditure in rats, while XOS and diet had an interactive effect on the respiratory quotient. (a) The average hourly energy expenditure was highest at nighttime in the LFD and the lowest measured energy expenditure was highest in the LFD at daytime; (b) The HFD diminished the production of CO₂ at daytime, whereas in O₂ consumption, no differences between the groups were found; (c) The respiratory quotient (RQ) values were calculated as VCO₂/VO₂. The different data points are shown with black dots. * indicates statistically significant difference between the groups.
