Associations between scheduled wake and sleep energy metabolism averaged across study days in study 1. A) correlation between wake and sleep energy expenditure, B) correlation between wake and sleep respiratory quotient (RQ), C) individual differences in wake and sleep energy expenditure, D) individual differences in wake and sleep RQ. Data for the 15 individual subjects are displayed along the x-axis for figures C and D, plotted according to the rank order of subjects’ 24 h energy expenditure shown in 5 A. Black line represent the line of identity and red line represents best linear fit.
