Equicaloric diets rich in either carbohydrate or fat have been used to study the comparative effects of carbohydrate and fat on protein metabolism. The body weight gain and the amount of food consumed of rats fed the high fat diet containing 25% casein for 15 days were a little higher than those of the high carbohydrate diet, but food efficiency was the same for both groups. Urinary output of nitrogen and urea were significantly low in the case of rats fed the high fat diet. The urinary nitrogen/consumed nitrogen ratio was also found to be less in rats fed the high fat diet compared with the high carbohydrate diet. There was no change in the protein digestibility between the high carbohydrate diet and the high fat diet. When pretein-free diets rich in either carbohydrate or fat were subsequent fed for 12 days, the changes of body weight and food consumption for both groups were essentially same. The amount of nitrogen and urea in urine was evidently lower in rats on the high fat diet than in those on the high carbohydrate diet. Thus, these results indicate an improved protein utilization when the high fat diet was fed.
