Core Tip

Core tip: A wide range of psychological conditions are bi-directionally linked to obesity. Psychological features may account for poor compliance and outcome in weight control programs but the current knowledge regarding this topic of research seems to be largely incomplete as studies investigating whether psychological factors could be reliable treatment predictors failed to give consistent results. The aim of the present narrative review is to critically analyze current literature in order to better identify which psychological features can predict outcome in weight loss and maintenance programs, and to summarize the psychological tools most widely used for this purpose.
