When the three days of dieting after the last injection are over, the patients are told that they may now eat anything they please, except sugar and starch provided they faithfully observe one simple rule. This rule is that they must have their own portable bathroom-scale always at hand, particularly while traveling. They must without fail weigh themselves every morning as they get out of bed, having first emptied their bladder. If they are in the habit of having breakfast in bed, they must weigh before breakfast.
It takes about 3 weeks before the weight reached at the end of the treatment becomes stable, i.e. does not show violent fluctuations after an occasional excess. During this period patients must realize that the so-called carbohydrates, that is sugar, rice, bread, potatoes, pastries, etc, are by far the most dangerous. If no carbohydrates whatsoever are eaten, fats can be indulged in somewhat more liberally and even small quantities of alcohol, such as a glass of wine with meals, does no harm, but as soon as fats and starch are combined things are very liable to get out of hand. This has to be observed very carefully during the first 3 weeks after the treatment is ended otherwise disappointments are almost sure to occur.
