 for the last date being actually 4.75 kg. greater than at the beginning 

 of the experiment in September.

Pec was one of the subjects who was definitely under the normal

 trained man, 44 years of age, and found great difficulty in losing weight. 

 Even on a very restricted diet the weight curve did not fall so rapidly as 

 one would expect. When at home, and also on a free Sunday, he found 

 difficulty in limiting the amount eaten, as may be noted subsequent 

 to November 11, when there was the usual gain of weight following a
