  ABSTRACT: Six albino rats were divided in two experimental groups and one control. The experiment began withfifteen days of free access; subsequently experimental groups maintained available three concentrationsof glucose: high, middle and low. First group received high-middle-low-high-middle-low sequence andsecond group received low-middle-high-low-middle-high sequence during six days. Control group notreceived glucose concentrations. Caloric concentration of food never changed. Results suggest thatmodification of caloric concentration in water affects feeding behavior. Nevertheless, water with glucoseconsumption did not change body weight.

  ABSTRACT: Six rats were exposed to three alimentary contexts, the first one, considered as habitual context, provided food only fora period of time. The second contained in the surface a cover of stones and allowed free access to the food until thesubject achieved the satiety state. The third context (novel) contained water in the surface and provided food during thetest phase. The food consumption was compared between the habitual context and the novel one after the subjectachieved the satiety state. The results show that in spite of the satiety the subjects consumed food in the novel context,but they didn’t consume food in the habitual context. These results are discussed in terms of how the contextinfluences the feeding behavior.
