e to handle a reasonable amount of
carbohydrates as well as other foods which have given more or less
trouble in the past.

The following schedule, after Joslin,[142] is included, and a careful
study of it is advised in order that the nurse may intelligently carry
out the Allen Treatment.

~Schedule.~--Fasting in many cases begins at once and the patient
experiences no ill effects from it. However, in severe, long-standing
cases many patients do better if the fats are omitted at once and the
rest of the diet left unchanged for two days. Then the proteins in the
diet are omitted and the carbohydrates cut in half. This halving of
the carbohydrates is continued daily until only 10 grams remain, after
which they too are omitted. The fast is thus made complete and remains
so until the urine is entirely free from sugar.

~Carbohydrate Tolerance~ is determined by giving, as soon as the urine
has been sugar-free for twenty-four hours, 150 grams of 5% vegetables.
This is equivalent to from 8 to 10 grams of carbohydrates. After this
5 grams of carbohydrates, or 75 grams of 5% vegetables, are added
daily to the diet until the patient is taking 20 grams. Then the
addition of 5 grams of carbohydrates is made every other day, using
the fruits and vegetables belonging to the 10% and 15% carbohydrate
group, until potatoes and oatmeal and finally bread can be tolerated
unless sugar appears in the urine before this or the tolerance reaches
3 grams to each kilogram of body weight or, in other words, until a
man weighing 150 pounds is consuming 225 grams of carbohydrates per
day.

~Protein Tolerance.~--In making the test for the protein tolerance it
is necessary to wait until the urine has been sugar free for
forty-eight hours; 20 grams of protein is then given. This is
equivalent to 3 eggs, and daily additions of 5 grams protein are made,
usually in the form of meat, until the patient is receiving 1 gram of
protein to every kilogram of his body weight per day unless his
carbohydrate tolerance is zero, in which case it is wise to add only
three-fourths of a gram of protein per day.

~Fat Tolerance.~--A determination of the fat tolerance is made
coincidently with that of the protein. No additional fat is allowed
until the protein tolerance reaches 1 gram per kilogram of body
weight, unless the patient's tolerance for protein is less than that.
After which 25 grams of fat per day are added until there is no
further loss of weight, tak
