Study hypothesis
This study is a community-based trial that will concurrently assess four commercial weight loss programmes. In addition to the primary outcome of percentage body fat loss, this study was designed to also examine changes in health risk, for example blood lipids, and psychological effects of these diets. Finally, the study will examine the practical aspects of adherence to the programmes by considering the subjective experiences of the subjects following the different programmes.
