The purpose of this study is to compare two different weight management delivery methods,
social media versus a traditional care model.
Obesity is a major public health issue as 68% of the US population is either overweight or
obese. Weight loss and weight loss maintenance is difficult. Traditionally, successful
weight loss programs are weekly behaviorally-based clinics which utilize a combination of
calorie restriction and physical activity. Traditional "face to face" weekly meetings may
not be feasible for everyone.
An alternative to provide weight loss and weight maintenance created by KUMC researchers
uses weekly group phone conference calls. While this method produced equal weight loss with
fewer burdens to participants when compared to the traditional "face to face" format, weight
regain during maintenance was still high.
This study will investigate a new delivery method (social media platform "Facebook")
compared to the group phone conference calls. In the social media platform participants will
be able to socialize with other participants in their group by commenting on posts from
other participants or posting messages themselves. Social media delivered programs have
potential to be a more a cost-effective approach to reach a large group of individuals.
