Abstract : Young male rats were fed one of three low-protein (5% casein) diets differing in the source of carbohydrate (sucrose, equal parts sucrose and cornstarch, or cornstarch) or a 20% casein (sucrose) diet at environmental temperatures of 24C or 5C. Replacement of sucrose with starch appeared to have a small but significant effect in increasing body weight gain for 15 days (but not the next 28 days) at 24C and also in animals exposed to cold for 28 days after a 15-day feeding period at 24C. In disagreement with results reported by Andik et al., cold exposure, although significantly increasing body weight gain and food intake in rats fed the 5% casein-starch diet, did not elicit a weight gain as great as that observed in 20% casein-fed animals at either 24C or 5C. The 24-hour food intake following a 24-hour fast exceeded the intake on the day before fasting on all diets for animals maintained at 5C but not 24C. The immediate (1/2 hour) and 24-hour food intakes of rats at 5C exceeded those of comparable dietary groups at 24C. At 5C, the 24-hour food intake, following the fast, of rats fed the 5% casein-starch diet exceeded that of the 20% casein-fed controls. (Author)
