Abstract: Restrained eaters and overweight and obese people are prone to increase their food intake during stressful situations. This study examines the impact of a stressful couple discussion on food intake in both spouses, while simultaneously taking into account the effect of BMI and restraint on this association. For 15min, 80 heterosexual couples discussed an aspect that they wanted their partner to change followed by an individual bogus taste test for the purpose of measuring his or her stress-induced food intake. Prior to and after the discussion, subjective mood state was assessed, as well as appetite perceptions, and the mood change before and after the discussion was calculated. Multiple regression analyses with a three-way interaction between mood change, BMI, and restraint were used to predict food intake for both men and women, while controlling for appetite perceptions. Only restrained women with a high BMI ate more when their mood worsened. For men, only appetite perceptions significantly predicted food intake. These results suggest that an induced negative mood in the form of a stressful couple discussion impacts food intake differently for men and women, and that particular attention should be given to the concomitant effect of both restraint and BMI when studying stress-induced eating among women.
