Figure. Mean reported weight of participants in the Herald-Sun 2005 Lose to Win challenge, Durham County, North Carolina. Mean weight is shown for all participants who reported weight each week. Lines are also shown for the subset of participants (n = 154) who reported weight on both the first and last week of the challenge, in total and by whether they participated with a group (n = 143) or independently (n = 11). Also shown is the week-by-week participation. A trend toward weight loss was reported among all subgroups, but standard deviations were wide and overlapped, so no between-group differences can be determined.
