Comparison of these figures shows that six of the men were practically of

the same body-weight at the close of the experiment as at the beginning.

Of the others, Oakman, Fritz, Cohn, and Bates lost somewhat. Bates,

however, was quite stout, and the work in the gymnasium as well as the

change of diet tended to reduce his weight. In fact, with the possible

exception of Oakman, the slight loss of weight these latter men underwent

was a distinct gain to their bodily condition. The most significant

feature, however, is to be found on scrutiny of the tables of results for

each man, where is seen the body-weight for each day of the six months.

Here it will be noticed that, as the experiment progressed, there was, as

a rule, a tendency for the body-weight to increase; this was followed by

a decline, after which the weight remained practically stationary. This

is well illustrated in Oakman’s case. Starting with a body-weight of 66.7

kilos on October 4, he reached 67.6 kilos on November 29, then declining

in weight to 62.3 on January 18, after which he remained practically

stationary, or varied only within narrow limits.

Finally, it should be said that the low proteid metabolism on which these

men were apparently maintaining body-weight was not associated with any

increase of non-nitrogenous food. At no time did the fuel value of the

daily food reach 3000 calories; in fact, about January 12 the average

fuel value of the food was only a little over 2000 calories per day.
