214 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



But one post-diet record of weight was obtained for this man, 

 showing that in 4 days the body-weight increased nearly 6 kg. This 

 rapid increase in body-weight must have been due in large part to an 

 increase in the water content of the body, for an addition of 6 kg. of 

 organized muscle or fat would have been impossible during this short 

 time. 



Body-weight curve of Gar (Fio. 60). 



The weight for Gar prior to the restricted diet was 71.25 kg. With 

 the reduced diet there was a consistent and steady fall in the curve 

 until the first record after November 11, which showed the rise com- 

 monly found after the unrestricted Sunday meal. The weight then 

 continued to fall and showed no increase during the Thanksgiving 



Kgs.

recess. A great increment appeared when higher feeding was resumed. 

 During the Christmas recess there was a gain of 5.8 kg. This 

 was followed by a rather rapid fall incidental to an extremely low 

 ingestion of food on the return to college, varied by one or two sharp 

 rises. The last 15 days the weight fluctuated around 64 kg., which 

 was evidently Gar^s lower limit of weight. During the post-diet 

 period there was the usual rapid rise in body-weight, with a total gain 

 of 9.5 kg. When the measurements ceased, the subject was somewhat 

 more than 1 kg. heavier than at the beginning of the observations.
