270 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



therefore, we have indicated the probable nitrogen and energy intake 

 of the men in Squad A on the uncontrolled days. Squad B, when 

 on diet, had no uncontrolled meals ; hence this problem of uncertainty 

 does not enter into the consideration of their results. 



Table 34. — Computed nitrogen and energy in Sunday diets'^ {uncontrolled), Squad A. 



* The uncontrolled diets of Sunday, October 14, 1917, were not reported. 



' The average nitrogen intake for these Sundays was 16.62 grams and the average gross energy 

 3,994 calories. 



In the last analysis, however, it should be borne in mind that these 

 men were, in a sense, on controlled diet even during these unrestricted 

 periods, for the actual control was the body-weight. They were 

 thoroughly educated in the belief that an increase in body-weight 

 indicated overeating. Judging from the character of the food in the re- 

 stricted diet, the men had evidently for the most part a relatively low 

 glycogen storage. We have every reason to believe that many of 

 the increases in weight noted with these men were due to the fact that 

 there was on the free days a liberal storage of glycogen, which carried 

 with it a large amount of water. This addition of water would ac- 

 centuate the increases in weight, a point which has been thoroughly 

 discussed in the section on body-weight. (See pp. 194 and 224.) On the 

 other hand, the men soon found that by rigid training the weight gain 

 could be rapidly lost and the original desired level speedily obtained. 



CALORIC ALLOTMENT. 



The caloric allotment with Squad A was determined primarily with 

 a view to lowering the body-weight to approximately 10 per cent 

 below the initial weight and subsequently providing sufficient calories 

 to maintain the body-weight at that level. It was believed that
