Satiety and cholecystokinin.

  • 1Department of Psychoendocrinology, University of Trier, Germany.


The effect of a fat and protein rich test meal of 800 kcal on subjective satiety ratings and on plasma cholecystokinin (CCK) 8-S was studied in 18 acutely ill patients with anorexia nervosa, 11 former anorectic patients, who were weight recovered for at least 4 years, and in 25 healthy young women. Eleven normal weight patients with bulimia nervosa were studied in the same experiment. Satiety ratings were significantly elevated in acutely ill anorectic and bulimic patients. CCK 8-S values were significantly stimulated by the test meal in all groups except from the bulimic group. Anorectic patients and weight recovered anorectics had normal values before and after the test meal. Bulimic patients had significantly lower values. These data suggest that CCK 8-S is not involved in the regulation of short-term satiety in anorexia and bulimia nervosa.
