If a meal causes distress, omit the next one and continue omitting meals until comfort and ease have returned. If the digestion is very weak, or if the illness has been protracted, do not feed solids as soon as recommended above. In all cases it is necessary to exercise self-control, moderation and common sense.
The meals must be moderate. Gradually increase until the amount of food taken is sufficient to do the necessary bodily rebuilding. The longer the fast, the more care should be exercised in the beginning. It is no time to experiment.
If the fast is to be of permanent benefit it is necessary to learn how to eat properly afterwards, and to put this knowledge into practice. This is the most important part to emphasize, yet all the books I have read on the subject have failed to pay any attention to it. In nearly every case the fast is necessary because of repeated mistakes in eating and drinking. Those mistakes built bodily ills in the first place and if the faster goes back to them they will do it again. The disease does not always take on the same type as it did in the first place, but it is the same old disease. During a fast there is recuperation because the body has a chance to become clean, and a clean body can not long remain unbalanced, provided there are no organic faults. By making mistakes in eating after the fast is over, the body again becomes foul and full of debris and that means more disease. Perhaps it may not require more than one-third as much abuse to cause a second break-down as it did to bring about the first one.
Some people fast repeatedly, and are somewhat proud of it. They should be ashamed of the fact that they must fast time after time, for it shows either ignorance or a weak, undeveloped will power. The fast should teach every intelligent being that it is an emergency measure, and emergencies are but seldom encountered in a well regulated life.
Food debauches following fasts should be avoided. A little will power properly applied will prevent them. Gross eating may compel another fast. We must eat and it is better to eat so that we can take sustenance regularly than to be compelled to go without food at various intervals. He who is moderate in his eating, uses a fair degree of intelligence in the selection of his food, is temperate in other ways and considerate and kind in his dealings with others will not be ill.
A fast is efficacious in clearing up a brain that is unable to work well because it is bathed in unclean blood. It is remarkable how well the brain works when the stomach is not overworked. Overfeeding the body causes underfeeding of the brain. On a correct diet the brain is efficient and clear and able to bear sustained burdens.
There is no question but that a fast, followed by a light diet, containing less of the heavily starchy and proteid foods and more of the succulent vegetables and fresh fruits, with their cleansing juices and health-imparting salts, would result in the recovery of over one-half of the insane. Most of them are suffering functionally and here the outlook is very hopeful. Christ cured a lunatic "by prayer and fasting." Proper feeding would work wonders in prisons. It would also be very beneficial for wayward girls and young men who are passion's slaves. St. Peter recommended fasting as an aid to morality, which is another evidence of the profundity of his wisdom.
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?
