Objective To examine the association of program delivery factors with weight loss (WL) in enrollees in iDiet ® , a commercial WL program. Methods Data were from 644 adults enrolling in an 11‐week group WL program and 461 who reported weight to 11 weeks (complete reporters). Predictors of %WL were analyzed using ANCOVA, including meeting type (in‐person vs. videoconference), participant type (worksite employees vs. community members), age, gender, BMI, and payment structure. Results Mean starting BMI was 32.4 ± 7.1 (mean ± SD); WL was 6.1 ± 3.9% in all enrollees in an intention‐to‐treat analysis and 7.4 ± 3.4% in complete reporters. Videoconference participants, older adults, and enrollees in incentivized programs were more likely to be complete reporters ( P < 0.004). %WL at 11 weeks was not associated with gender, starting BMI, or videoconference versus in‐person groups. Worksite participants had greater %WL than community participants (+1.2%, P < 0.001), and there was no significant difference in %WL between programs paid by the employee or employer. Greater %WL was achieved by individuals ≥30 versus < 30 years (+2.2%, P < 0.001) and by those enrolling in January‐March versus April‐June (+1.4%, P = 0.02). Conclusions iDiet participants had clinically impactful mean WL. The observed high mean WL in worksites and videoconference‐delivered programs broadens options for scalable WL program implementation.
