title: Distress and eating: why do dieters overeat?
abstract: OBJECTIVE
  It has been shown that distress suppresses eating in nondieters (unrestrained eaters), but increases it in chronic dieters (restrained eaters). This study attempted to investigate several possible explanations for this phenomenon, in particular, the "masking hypothesis." This hypothesis states that dieters use overeating to mask their distress in other areas of their lives by eating when distressed so that they can attribute their distress to their overeating rather than to more uncontrollable aspects of themselves or their lives. In addition, comfort, learned helplessness, and distraction explanations were investigated.
  
  
  METHODS
  Female college student subjects were led to believe that they had or had not failed at a cognitive task, then were either given ad libitum or just three small spoonfuls of ice cream to taste and rate.
  
  
  RESULTS
  It was predicted that restrained subjects who ate ad libitum following failure would attribute more of their distress to their eating than would those who were allowed only a taste of ice cream. The results were more complicated than predicted. They indicated that the masking, distraction, and helplessness hypotheses all received some support in the present study and that they may work in tandem with each other.
  
  
  CONCLUSIONS
  The results suggest that distress-induced overeating in restrained eaters may serve psychological functions for the individual, allowing for distraction from the distress or masking of the source of dysphoria. The possible relevance of these results to bulimic patients who may use their binges to mask the true source of their distress is discussed.
