ABSTRACT
Web-based dietary interventions have been widely used to change people's dietary behaviors and improve their health. Copious features and technologies have been developed and used: from a simple HTML page to interactive online games. Due to the variety of these features, a practitioner who plans to create or improve an intervention website may wonder which features should be used to maximize the impacts of a web-based intervention. Unfortunately, in spite of extensive literature review, we failed to find straightforward guidelines for practitioners. Thus, the aim of this study is to collect preliminary information to eventually create practical guidelines. We selected 4 7 papers regarding web-based dietary interventions and reviewed the papers to identifY what kinds of technologies have been used and how these have impacted on measured outcomes. Through this review, we identified several interesting patterns, and their implications were discussed.
