Growth of Walker 256 carcinosarcoma depresses the hyperingestive response of rats to dilution of food with nonnutritive bulk. The depression is much less marked when the dilute diet is presented continuously over a long period than when it is presented for 1 week at a time. It is likely that over the long term another mechanism of food control is invoked to which the tumor-bearing rat has not lost its sensitivity. There is no reduction in feeding response of tumor-bearers to insulin-induced hypoglycemia, so feeding response to hypoglycemia could be the compensatory mechanism invoked. Prolonged exposure to the dilute diet with resultant decrease in nutrient intake by the tumor bearer increased the rate of deterioration of the host but did not significantly affect tumor growth.
