Abstract
In case of a restricted calorie intake, the effect of the amount of food protein on the nitrogen balances of albino rats and overweighted women was investigated.
The calorie of the diet was restricted by half of the normal diet. And an overweighted women group and a group of albino rats were fed by a high protein diet, while the other group of albino rats were fed by a low protein diet.
The weight of low protein group decreased remarkably more than that of high protein group. Notwithstanding the decrease of weight, the nitrogen balance of high protein group and the women group was positive, while that of low protein group was negative. The xanthine oxidase activity and the transaminase activity of the liver of high protein group was higher than that of low protein group.
