How long should a fast last? Until its object has been accomplished. It is rarely necessary to fast a month, but sometimes it is advisable to continue the fast for forty days, or even longer. If the fast is taken on account of pain, continue until the pain is gone. If for fever, until there is no more fever. In chronic cases it is not always necessary to continue the fast until the tongue is clean. When the patient is free from pain and fever and comfortable in every way, start feeding lightly. People who are thin and have sluggish nutrition, one symptom of which is dirty-gray mucous membrane in mouth and throat, should not be fasted any longer than it is absolutely necessary, for they generally react slowly and poorly. If people would miss a meal or two or three as soon as they begin to feel bad, no long fasts would be necessary, because when the system first begins to be deranged it very quickly rights itself when food is withheld. It is impossible for a serious disease to develop in a fasting person, unless he is in an exceptionally bad physical condition at the beginning of the fast, for when food is withheld there is nothing for disease to feed upon. No new disease can originate during a fast. Fasts often bring people back to health, who can not recover through any other means known to man, unless it be eating almost nothing--a semi-fast. Occasionally a patient dies while on a long fast or immediately thereafter, but please remember that millions die prematurely on this earth every year who never missed their meals for one day. Also remember that those who go on prolonged fasts are generally "hopeless cases," who have been given up to die by medical men. People who fast generally become comfortable, so why envy a few men and women an easy departure when they are no longer able to live, and why heap undeserved censure on those who are doing their best to ease the sufferers by means of our most valuable therapeutic measure, fasting? There is much prejudice against fasting, but a calm study of the facts will remove this. Typhoid fever, conventionally treated, often proves fatal in 15 per cent. or more of the cases and those who survive have to undergo a long, uncomfortable illness which often leaves them so weakened and with such degenerated bodies that the end is frequently a matter of a few months or years. Pneumonia and tuberculosis find a favorable place to develop and in these cases prove very fatal. On the other hand, cases of typhoid treated by the fast, and the other hygienic measures necessary, recover in a short time, there are no evil sequels and the body is in better condition than it was before the onset of the disease. I have never seen a fatality in a properly treated case, and the mortality is conspicuous by its absence. It is the same in curable chronic diseases. Where feeding and medicating add to the ills, fasting with proper living afterwards brings health.
