Energy intake and energy restriction during each phase of the trial. Values reported as mean ± SEM. A. Mean energy intake during the control phase, and on feed and fast days during each week of the trial. Energy intake did not change from the beginning to the end of the control phase. *P < 0.001 fast day energy intake was lower than feed day energy intake at each week (One-factor ANOVA with Bonferroni analysis). B. Mean percent energy restriction during each week of the study. No difference for percent energy restriction between weeks (One-factor ANOVA with Bonferroni analysis).
