1 All values reported as mean ± SEM. Data for all variables were collected over a 7-d period at baseline (prior to the commencement of the study) and week 12 in the TRF and control groups. Data were included for 46 participants; means were estimated using an intention-to-treat analysis using last observation carried forward. 2Baseline variables: No difference between groups for any parameter (Independent samples t-test). 3 P values reported for the time restricted feeding group relative to the control group (group×time interaction) using repeated-measures 2-factor ANOVA.
