RESEARCH

My students and I investigate the biobehavioral mechanisms by which high-fat foods promote overeating and weight gain. We study the contribution of oral, gastric and postgastric signals; the role of learning and experience; and the integration of the signals in the control of meal size and satiety. Recently we have shown that fat calories are less effective than carbohydrate calories in entraining anticipated satiety (Warwick et al., 1997), and that the behavioral expression of high-fat diet overeating includes both larger meals and reduced satiety (Warwick et al., 2000).
