522 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



Table 133. — Heat production at different diet levels as computed from respiration experiments 

 and as predicted by Harris and Benedict — Squad A; subjects post-absorptive and in lying 

 position — continued. 



^ The period at the end of the reduced diet represents 5 experiments on or about Jan. 26, 1918.

derived from a series of prediction equations, it is obvious that the 

 basis of comparison is much more fundamentally and firmly estab- 

 lished than when the comparison is made on the basis of body-weight 

 or body-surface. 



It is seen, therefore, that not only on the basis of body-weight, as 

 shown in earlier tables, as well as the questionable basis of body- 

 surface, but also from these biometric prediction values, the basal 

 metaboHsm was profoundly lowered with every member of Squad A. . 

 It is furthermore of significance that of the four men with pronounced 

 negative values in column g on the normal diet, namely, Bro, Can, Tom, 

 and Vea, three of them, Bro, Tom, and Vea, show absolutely greater 

 negative values at the end of the experiment than all of the other sub- 

 jects except Pea, thus suggesting a tendency to retain a relative posi- 

 tion in the group so prominently indicated in the positive values noted 

 with Mon. 



GROUP MEASUREMENT OF BASAL METABOLISM WITH LOW DIET, SQUAD B. 



Immediately following the night of January 6 inside the respira- 

 tion chamber. Squad B was put upon a much restricted diet which 

 averaged 1,375 net calories. The men came to Boston for experi- 

 ments in the group respiration chamber on January 13, 19, and 27,
