On successive days advances can be made from Test Diet 1 to Test Diet 5, and if on the fifth day the patient is not sugar free, fasting can be employed for one or more days. The Maintenance Diets are for use so soon as the urine of the patient is free from sugar. If this occurs as a result of Test Diet 5 the patient begins with Maintenance Diet C1PF1. The actual articles of food representing the carbohydrate in the diet for the first day are given under the heading of carbohydrate, for convenience described C1, 2, 3, etc. The articles referred to under protein and fat are under that heading, which for the same reason is described as PF1, 2, 3, etc. Certain cases of diabetes can proceed steadily day by day from C1PF1 to C12PF12, without showing sugar. If sugar does appear in the urine, drop back two days in the carbohydrate group, wait till sugar free, then advance in the protein and fat group until sufficient calories are obtained. Thus, if sugar shows on C7PF7 the diet prescribed would be that included in C5PF7 and thereafter progression could be made in the PF group until twenty-five to thirty calories per kilogram body weight were furnished the patient. Occasionally the patient becomes sugar free on Test Diet 2, 3, or 4. It is then unnecessary to begin with Maintenance Diet C1PF1, but instead with a maintenance diet which contains a value for carbohydrate similar to that of the test diet upon which the patient became sugar free. If the protein and fat are too high for the individual on a given day it is easy to advance the carbohydrate and decrease to an earlier day on protein and fat. The plan is arbitrary and the majority of cases will demand some modification. It is arranged to enable patient or nurse to see in advance the general plan of treatment.

If the case is a mild one, this may be sufficient to free the urine from sugar, but the diet is given primarily to enable the physician to find out by means of urinalysis just how great is the functional impairment. In some cases, which are mild in character, the urine is made free of both sugar and acetone without further dietetic measures. However, when a severe diabetes is manifested and a high percentage of glucose and in some cases acetone bodies are found in the urine a more rigid treatment will be found necessary.
