Chronic diseases, such as obesity and diabetes, are leading causes of mortality globally. Prevention of such chronic diseases typically requires critical diet changes to improve diet quality. Studies suggest that consistent diet-tracking can lead to improvement in diet quality. In this regard, smartphones have enabled diet-tracking through numerous apps for healthy eating and diet monitoring. However, these apps often suffer from high non-adherence, which prevents them from providing potential benefits to the users. Thus motivated, this work aims to model and identify predictors of adherence to diet app use, and particularly, the role of coaching. Preliminary analysis was done using panel data obtained from a diet app, and shows that coaching advice in addition to demographic variables can predict adherence. This study thus provides initial findings to help understand how to improve adherence to diet apps, as an enabler for improving diet quality and health outcomes.
