As the loss is not great, and indeed quite within the range which is 
observed in the weight of persons under normal conditions during a 
period of equal duration, it would seem fairer to give the diet much 
credit for being able to carry an active, energetic, healthy man through 
a period of unusual strain, both physical and mental, attendant upon 
some' special work in addition to his regular college duties. 
DIETARY STUDY OF A FRUITARIAN (NO. 363.) 
The study eommeneed April 23. 1902, and continued for ten days. 
The subject was a man who had been experimenting with the fruitarian 
diet for several years. He was 25 } T ears old and did not gain or lose 
weight (without clothes), the weights for the different days, with the 
exception of the third and ninth days, when no weight was recorded, 
being 151.1, 153, 151.3, 153.1, 118.1, 150.3, 150.8, and 151.1 pounds. 
On the fifth day the subject ate no supper and on the ninth day no 
lunch. On other days three meals were eaten. The total number of 
meals taken was therefore 28, which in this case was assumed to be 
equivalent to one man for ten days. 
The details of the studv are shown in Table 13.

This diet furnished practically 68 grains protein per da} T , or about 
two-thirds the amount called for by the commonly accepted standards 
for a man at light muscular work. The fuel value, however, slightly 
exceeded the limits of the standard. 
Notwithstanding the variety of foods in this diet which were selected 
b\ T the subject, it did not furnish as much protein as did the diet limited 
by the experimental conditions and consisting of bananas, oranges, 
and almonds, used in a digestion experiment (No. 116, Table 19) with 
the same subject.
