Abstract: | For each of five pair of diets, 20 weanling rats were equally divided into ad lib and restricted water groups. Caloric density, palatability, as well as nutrient composition of the diet pairs were manipulated. Though lower in absolute food intake than controls, water-restricted rats took a larger proportion of their food from diets lower in protein content and higher in fat content, regardless of caloric content or palatability. The results demonstrate both a quantitative and qualitative dietary adaptation to water restriction. |
