because we have been tempted by
dainties in the past and have formed
the habit of eating too much. To
prove these statements the professor
has made experiments. He tried the
theory on mental workers, on, men
doing moderate physical work, and on
athletes.
Statistics made under the govern
ment authority, and with $4,000 per-
sons contributing, show that the daily
consumption of protein, or tissue
forming material, ranges from LOO
grams in the case of man at seden-
tary work, to lis grams by man
doing hard manual labor. The Gallo
ries or heat units required to sup
ply heat and bodily energy by oX1da-
ton range from 200 to $500 a day.
These statistics nave been taken to
show that men need such amounts or
food because the appetite Graves them
and the average subject is found to
eat them in such quantities. Prof.
Chittenden's experiments have been
made to show that these quantities
of nutriment are determined by habit,
which may be easily broken, and are
not required to sustain bodily weight.
health and energy.
Six Yale professors and instructors
were the subjects under his first class,
the mental workers. Regulation and
study of their diet for periods from
six months to two years showed that
an average intake of SO grams of pro-
ted was sufficient, with fats and car
bohydrates enough to yield fuel
value of 1000 calories. They MAIN
tanned this rate Of eating without los
ing in weight, after the first few days,
and all reported a gain in their gener-
al health, mental vigor and energy,
indicating that removal of the over
load was benefit. Within few days
they ceased to crave larger quantities
of food, showing that they were not
needed but called for by habit.
A detail of thirteen men from the
army hospital corps were subjects for
the second experiment, to show the
amount of nutriment needed by men
doing moderate muscular work. These
men performed their daily duties,
largely manual labor, took systematic
with a food intake of SIS grams of pro-
ted, and a fuel value Of $500 calories.
They saved half their former con-
sumption of heterogeneous food, and a
good share of the fat and carbohy-
drate.
squad of Yale athletes were sub
jects Of the third experiment. They
had labored under the idea that men
must be stuffed with muscle build
ing food, and had taken $50 grams
of proteid daily, with a total fuel
value of 4150 calories. They reduced
their food supply to Sc grams of pro-
teids in one case, and Y in another,
with a fuel value Of $500 to 5000 cal
cries. During five months of this diet
they felt no i'll effects, and one man
gained an intercollegiate champion
ship while on the restricted diet. A
marked feature of the experiment was
that both soldiers and athletes gained
| in bodily strength during the test,
according to careful experiments.
| The main features of the restricted
| diet, as arranged by Prof. Chittenden,
| are a reduction in the amount Of
meat, and an increase in the vegeta-
BILE diet, which will give equal bulk
without an excess of proteid. This
diet, he maintains, will reduce the
strain On the organs of the body, re-
lieve it of unnecessary combustion
and make for better health and better
minds. The success of the expert
ments ought to give support to the
| theory, and the promised results are
desirable enough to make it worth
| trying.
