did not furnish enough protein to supply the demands of the body under the 

 conditions prevailing during the experiment. 



Fat. The amounts of body fat actually katabolized (obtained from column 

 g of table 51) are recorded in line e of table 64, and the amount of fat in terms 

 of body fat computed to have been absorbed from the food is recorded 

 in line d. There was a marked gain of fat on the first day following the fast,

a slight gain on the second, and an insignificant loss on the third day. For 

 the three days there was an average gain of 12.78 grams of fat, showing that 

 on the average the diet supplied a little more than was actually needed and 

 thus the body was enabled to store fat. 



Carbohydrates. The amounts of body carbohydrate or glycogen katabolized 

 each day recorded in line h are taken from the data in table 51, while in line g 

 the amounts of body carbohydrate computed from the elements absorbed in the 

 food (see table 61) are recorded. There was a gain of carbohydrates on the 

 first two days of the experiment, while on the third day there was a loss.
