EFFECT OF VARIATIONS IN NUTRITIVE DENSITY ON INTAKE OF FOOD OF DOGS AND RATS

Abstract

The intake of food in the dog and rat was measured under conditions in which the nutritive density of the diet was varied. Although compensatory adjustments in food intake were made in keeping with the caloric value of the available diet, marked adjustments were made. The tendency to ingest a constant avg. daily volume of food, "eating for bulk," was modified only slowly and incompletely by the tendency to balance caloric deficits, "eating for calories." A factor of palatability is probably also concerned in these adjustments of food intake.
