title: Stress-related cortisol response and laboratory eating behavior in obese women.
abstract: Stress-related cortisol secretion has been linked to increased appetite and subsequent food intake in overweight individuals. The present study addresses this relationship in a repeated-measures randomized controlled laboratory experiment. Nineteen obese women were compared to 36 normal weight controls with respect to stress-induced salivary cortisol and laboratory eating behavior, measured by a universal eating monitor. The trier social stress test served as stressor. Stress-induced cortisol levels were significantly higher in the obese compared to the normal weight controls. Unexpectedly, a corresponding increase in laboratory food intake was not detected. The results are interpreted and discussed with regard to restrained eating, which was found to be present to a significant degree in the obese women.
