Abstract
BackgroundThe current study set out to improve our understanding of the characteristics of individuals who are motivated to restrict their food intake yet who nevertheless fail to do so. We examined whether punishment sensitivity (PS) was related to restrained eating, and reward sensitivity (RS) to perceived dieting success. Additionally, it was examined whether executive control (EC) moderates the association between RS and perceived dieting success.MethodsFemale student participants (N = 290, aged 17–29, BMI between 18.5 and 38.0) completed questionnaires on restrained eating, perceived dieting success, RS and PS, and carried out a behavioral task to index EC.ResultsPS was indeed positively related to restrained eating. RS was positively related to perceived dieting success, yet, EC did not moderate this association.ConclusionThe current study adds to the evidence that PS is related to individuals’ motivation to restrict their food intake. Furthermore, it shows support for the suggestion that RS may facilitate food restriction.
Highlights
Many people attempt to decrease their weight by restricting their food intake (Wardle et al, 2006; De Ridder et al, 2014)
In the group of individuals who report to be dieters restrained eating was weakly related to less perceived dieting success and a higher Body Mass Index (BMI)
The main findings can be summarized as follows: (1) punishment sensitive (PS) was positively related to restrained eating, and (2) reward sensitivity (RS) was positively related to perceived dieting success of dieters
Summary
Many people attempt to decrease their weight by restricting their food intake (Wardle et al, 2006; De Ridder et al, 2014). They often fail to adhere to their diet (Knäuper et al, 2005), or they regain their weight after initially having lost it (Field et al, 2007). The current study set out to improve our understanding of the characteristics of individuals who are motivated to restrict their food intake yet who fail to do so. We examined whether punishment sensitivity (PS) was related to restrained eating, and reward sensitivity (RS) to perceived dieting success. It was examined whether executive control (EC) moderates the association between RS and perceived dieting success
