Pounds Off Digitally Study: A Podcasting Weight Loss Intervention

We will conduct a weight loss intervention study among adults. Using the weight loss podcast
that receives the highest rating from a previous content analysis, we will conduct an
intervention comparing the best existing weight loss podcast to an enhanced podcast. The
enhanced podcast will be based on theoretical constructs that have been shown to be
effective in producing weight loss in other research studies. We will then evaluate the
effectiveness of podcasting to promote weight loss in adults. Weight change from baseline to
12-weeks and changes in psychosocial measures will be used to assess differences between the
existing podcast, enhanced podcast, and control conditions. In conclusion, this research
study aims to find innovative and inexpensive ways to help people lose weight. Podcasting
has the possibility of reaching a wide range of age and ethnic groups and will allow people
to receive weight loss information when and where it is convenient for them.
