360 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



beginning, in digestive disturbances which bordered on nausea 

 and occasionally provoked diarrhea. This tendency to overeat, with 

 consequent digestive disturbance, persisted more or less throughout 

 the entire experiment in spite of repeated warnings. 



In a number of instances there appeared to be clear evidence of 

 so-called hunger pains. Certain of the men complained of a con- 

 tinuous gnawing sensation in the stomach, headaches, inability to 

 study, etc. These minor disturbances were anticipated; in fact, 

 the men were told at the beginning that discomfort might be ex- 

 perienced as a result of the restriction in diet. Only one subject 

 found it necessary to withdraw on this account. Fre, three weeks 

 after the beginning of the experiment, found himself discommoded 

 by the feeling of hunger and the time demands of the experiment. 

 He became very much disturbed, and, on the advice of the physician, 

 withdrew from the squad. At first his physician suspected the 

 discomfort might be due to a gastric ulcer, and with this possibility 

 it appeared unwise to continue him on the squad. As a matter of 

 fact, when full diet was resumed all his symptoms disappeared. 



At least three of our subjects underwent ether narcosis for minor 

 operations during the research. Thus Bro injured his foot in a foot- 

 ball game and, as shown in his personal history (see p. 47), under- 

 went ether narcosis for a resetting of the toe. He experienced no 

 difficulty and made a rapid, uneventful recovery. Kon underwent 

 ether narcosis for a throat and nose operation which involved the re- 

 moval of adenoids and tonsils, trimming of turbinated bones, and 

 straightening of the septum (see p. 48). Tom, in the Christmas 

 vacation, was operated on for hemorrhoids under ether narcosis, but 

 evidently returned to college too soon after the operation. Yet we 

 have no reason to believe that the fact that he was on low diet in any 

 way delayed his ultimate recovery. His post-dietetic history shows 

 that he finished his college work in good condition and, in fact, was 

 one of the best students in the institution. 



The post-experimental history of practically all the men in both 

 squads showed pronounced digestive disturbances following the return 

 to normal diet. Special cautions were given to resume normal 

 diet very slowly, but the men not only overate but, in certain instances, 

 passed all reasonable bounds. The reports of the meals eaten by some 

 of the men are so amazing as to seem of doubtful value and hence are 

 not recorded here. Many suffered from abdominal pains and distress, 

 not infrequently nausea, but usually all the men were in good condition 

 within 2 or 3 days. 



The most pronounced and puzzling development of abnormal nature 

 throughout the entire test was that occurring with Spe. In the experi- 

 ments in the group chamber apparatus on the morning of December 9 

 his rectal temperature at 6 a. m. was 97.6° F., and pulse rate 53. On
