Changes in body weight (kg; mean±s.e.m.) during baseline and 16 weeks of energy restriction (ER) in the continuous (CON; N=19) and intermittent (INT; N=17) groups. (a) Cumulative weight change (kg) over baseline (−4, −2, 0 weeks) and after 4, 8, 12 and 16 weeks of ER for the CON and INT groups. *Significant difference between groups; P<0.05. #Significant difference from baseline within-group; P<0.01. (b) Weight change (kg; mean±s.e.m.) in the intermittent energy restriction (INT) group during each of the 8 × 2-week energy restriction (ER) and 7 × 2-week energy balance (EB) blocks that comprised the 30-week intervention. Data are from participant-reported weights measured at home (N=20 except N=19 for ER5, EB5, EB6, ER7 and EB7, and N=17 for ER8). Weight change is calculated as the difference in weight measured from Day 1 of one block (for example, ER1) to Day 1 of the subsequent block (for example, EB1). Participants were instructed to record weight daily throughout the study. The majority (80% or 256/312) of measurements were taken on Day 1 of the block (as instructed), and 93% (299/312) of measurements were taken within ±1 day of Day 1.
