228 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



^ Weight obtained Oct. 28, 1917; weight on Oct. 7 was 67.3 kg. 



' Weight obtained Dec. 16, 1917; Lon did not come to Boston with Squad B on Jan. 6, 1918. 



* Weight obtained on Dec. 13 just before subject left the squad. 



mum loss was again found with Tom, with a percentage loss of 7.4 

 per cent. The average loss for the entire squad was 10.5 per cent. 

 This is of special interest, as it will be recalled that the effort was made 

 to secure an average loss in weight for these men of 10 per cent, and 

 all of the men, except Tom, were able to reduce their weight to this 

 extent. Pec found this reduction difficult, but was finally able to 

 exceed the 10 per cent limit slightly. Thereafter he was given a little 

 more freedom in diet, with a consequent increase in weight, so that 

 the loss at the end of the experiment was but 8.1 per cent. 



The diet experiment with Squad B continued for but three weeks. 

 The loss recorded at the end of the period ranged from a minimum of 

 2 kg. with Kim to a maximum of 5.8 kg. with How. Aside from the 

 low values found with Kim and Wil, there is a striking uniformity in 

 the losses of the members of this squad. The percentage losses show 

 this general uniformity clearly. If we exclude the percentage losses for 

 Wil of 4.8 per cent and Kim of 3.2 per cent, the range is from How, 

 8.1 per cent, to Fis, 6.0 per cent, with a general average loss of 6.5 per 

 cent. 



POST-DIET INCREASES IN BODY-WEIGHT OF SQUAD A. 



Although numerous experiments could be made upon a squad of 

 men at the lower nutritional level and during the recuperation period, 

 io was impracticable to make further observations, since a number of
