212 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



nearer a 10 per cent than a 12 per cent loss. It was found that 2,380 

 calories practically sufficed to hold the weight at this level. The 

 post-diet increase in body-weight was striking, that is, from 69.3 kg. on

February 3 the body-weight rose with hardly a break to 80 kg. on 

 February 21. This represents an increase of 10.7 kg. in less than three 

 weeks. The tendency at the end of the observations was for the body- 

 weight to be slightly higher than the initial weight, our last record for 

 this man being 81 kg. or 1.25 kg. greater than the first record. 



BODT-WEIGHT CURVE OF KON (FiG. 59). 



From the statistical records for Kon, it will be observed that he did 

 not begin the reduction in diet until some time after the other men in 

 Squad A, as he was originally a member of Squad B. His body- 

 weight as noted on October 7 was 67.25 kg.; during the next three 

 weeks it rose to 69 kg., at which point he began the reduced diet. The 

 basal energy values found for this man were unfortunately confined 

 to only two days, but averaged at this time about 3,000 calories. He 

 readily consented to the proposition to make a sharp reduction in the 

 diet in the attempt to have him reach the 10 per cent lower weight- 

 level about the same time as the other members of Squad A. Conse- 

 quently he was given only a little over 1,500 calories, which, as the 

 curve shows, caused a rapid fall in the body-weight.
