The stress-eating paradox: Multiple daily measurements in adult males and females

The stress-eating relationship was examined in a prospective study of 158 subjects who completed daily records of stress and eating for 84 days, yielding 16, 188 person days of observation. Using both within-subjects and between-subjects analyses, individuals were much more likely to eat less than usual than to eat more than usual in response to stressful daily problems. The likelihood of eating more did not change as severity of stress increased, but the likelihood of eating less increased substantially. There were also clear gender differences. Males had a slight tendency to eat less than to eat more across all levels of stress, except at the highest level, where eating less occurred much more frequently. In females, the tendency to eat less as opposed to eating more emerged at middle levels of stress; at the highest level of stress, females were more than three times more likely to eat less than to eat more. Individual subjects were highly consistent over levels of stress in the direction of eating; 82% of the subjects were consistent in eating more or less over the majority of their stressful periods. These results show a clear effect of stress on eating, with eating less being the predominant response. © 1994, Taylor & Francis Group, LLC. All rights reserved.
