The changes of body weight and gastrointestinal motility as well as the changes of isolated small intestine segments and serum gastrointestinal hormones in food-interfered and control groups. I. A body weight; B intake of energy; C the ration of gastric empty in CON, DIO and DR groups. D the rate of intestinal transiting in CON, DIO and DR groups. E the ratio of wet/dry fecal weight in DIO and DR groups. II. A the summary of peak changes of duodenum and ileum; B the summary of frequency changes of duodenum and ileum; C the changes of serum cholecystokinin (CCK); D the changes of serum motillin and plasma gastrin. CON: the group of basic diet control; DIO: the group of diet–induced obesity; DR: the group of diet-induced resistance. *p < 0.05, **p < 0.01, compared to the CON group. #p < 0.05, ##p < 0.01, compared to the DIO group.
