Dr. Warwick's research investigates 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. Recent findings include:
The dose-response relationship between dietary fat content and spontaneous caloric intake in rat (Warwick, 2003)
High-fat foods promote overeating via mechanisms that are independent of palatability (Warwick et al., 2002)
The behavioral expression of high-fat diet overeating includes both larger meals and reduced satiety (Warwick et al., 2000; Warwick et al., in press).
Fat calories are less effective than carbohydrate calories in entraining anticipated satiety (Warwick et al., 1997)
