At baseline, mean (SD) weight was 105.5 (17.6) kg. At 6 months, those in the LF group had reduced initial weight by 8.6% (95% CI 7.2–10.0%), those in the LC group by 10.4%(8.9–12.0%), and those in UC group by 2.3% (1.3–3.2%) (Table 2). Participants in the intervention arms lost more weight than those in the UC arm (10.3 [95% CI 9.2–11.5] vs. 2.8 [1.6–4.1] kg, P , 0.001). At study end, maintained weight loss was greater in the intervention arms (8.2% of initial weight) than in the UC arm (2.5% of initial weight, P , 0.001).
