title: Exercise program-induced mood improvement and improved eating in severely obese adults.
abstract: BACKGROUND
  Using a practical setting, this study aimed to test exercise and nutrition interventions' effects on negative mood, self-regulation, and self-efficacy to control eating; and to assess the ability of mood change to predict changes in eating behavior, while accounting for changes in self-regulation and self-efficacy.
  
  
  METHODS
  Severely obese adults participated in a cognitive-behavioral exercise support treatment paired with either nutrition education (n = 140) or cognitive-behavioral methods applied to improved eating (n = 146). They were assessed on measures of overall negative mood, self-regulatory skill usage, self-efficacy to control eating when negative moods are present, and fruit and vegetable consumption at baseline and Week 26.
  
  
  RESULTS
  Significant improvements in each psychosocial variable and fruit and vegetable intake were found. Improved mood significantly predicted fruit and vegetable consumption change, R2 = 0.12, P < 0.001. Entry of changes in self-regulation and self-efficacy into the multiple regression equation significantly strengthened the variance explained, R2 = 0.18, P < 0.001.
  
  
  CONCLUSIONS
  Findings suggest that exercise-induced improvements in mood improve eating behaviors, with increases in self-regulation and self-efficacy adding to this effect.
