Abstract
As obesity rates rise, new weight loss methods are needed. Little is known about the use of podcasting (audio files for a portable music player or computer) to promote weight loss, despite its growing popularity.
A 12-week randomized controlled trial.
Overweight men and women (body mass index, 25–40 kg/m2) (
In 2008, participants were randomly assigned to receive 24 episodes of a currently available weight loss podcast (control podcast) or a weight loss podcast based on social cognitive theory (SCT) designed by the researchers (enhanced podcast) for 12 weeks.
Weight was measured on a digital scale at baseline and follow-up. Both groups also completed questionnaires assessing demographic information, food intake, physical activity, and SCT constructs at the introductory and 12-week meetings. Additional questionnaires at the 12-week meeting assessed perceptions of the intervention.
Data collection and analysis occurred in 2008 and intention-to-treat was used. Enhanced group participants (
The results of this study suggest that the use of behavioral, theory-based podcasting may be an effective way to promote weight loss.
