PLoS Med ; 17 8 : e, Participants were recruited in Mayand the intervention took place between June and December The intervention involved 12 weekly min face -to- face sessions, incorporating physical activitynutritionand behaviour change information and practical activities delivered by coaches at 2 clubs.
Data were collected at baseline and immediately postintervention. For trial feasibility purposes, 6-month follow-ups were completed.
Outcomes were differences in weight loss primary outcome and recruitment and retention rates, self -reported measures for example, psychological well-beingdevice -measured physical activitywaist size, and blood pressure at 3 months. No adverse events were reported. At 3 months, mean difference in weight between groups, adjusted for baseline weight and group, was 3.
The intervention group's moderate-to-vigorous physical activity MVPA was higher than the control group by 8. Issues with retention were a limitation of this trial. In a futurefully powered randomised controlled trial RCTretention could be improved by conducting assessments outside of holiday seasons.
