It will be noted on referring to the above tables that the subjects 

 ate on an average 22 grams of protein, 90 grams of fat, and 367 grams 

 of carbohydrate daily, which had a fuel value of 2,366 calories. The 

 protein, fat, and carbohydrate supplied by the total diet were 50.9 

 per cent, 90.5 per cent, and 97.6 per cent digested, respectively. When 

 corrections are made for the metabolic products and undigested fat 

 resulting from the basal ration occurring in the feces the value, 90.5
