Limited Capacity for Motor Activity as a Cause for Declining Food Intake in Cancer

Abstract

The association between decline of food intake and decline of spontaneous motor activity was examined during the growth of 3 transplantable tumors in rats. In 2 carcinomas, the quantitative association was consistent with the postulate that a cause of decline of food intake during tumor growth is the progressive incapacity to undertake the motor activity of feeding. This could account for only a small part of the decline of food intake in the host/hepatoma organism.
