The faster loses weight, at first often as much as two pounds a day. This is mostly water. After the first ten days the loss may be but one-half of a pound, or less, per day. The loss of weight is greatest in heavy people and in those who have high fevers.
The tongue becomes badly coated, and the breath foul, showing that the mucous membrane is busy throwing out waste. The tongue remains coated until the system is clean, and then it clears off. Most people feel weak when they attempt to walk or work, but they feel strong when resting. Others, who are badly food-poisoned, gain strength as the system eliminates the harmful substances from the body. For a day or two the craving for food may be quite insistent and persistent. Then hunger generally leaves and does not return until the tongue is clean. The mind becomes clearer as the body becomes cleaner. This benefit to the spirit, or the soul, has been recognized by religious organizations for centuries.
A little discharge of blood from the bowels at first should cause no alarm. In some cases a great deal of yellow mucus is thrown into the lower bowel. The liver at times throws off so much bile that it makes the patient alarmed. This should cause no uneasiness. When the bile is forced upward into the stomach it is very disagreeable. The discharges from the bowels are often very dark.
There is a tendency toward chilliness, especially to have cold hands and feet. Skin eruptions and heart palpitations are occasional symptoms. Nervous, irritable and fearful people have symptoms too numerous to mention. The more they are sympathized with the worse they become.
Many medical men have misinterpreted the symptoms of the fast, and hence they have condemned the procedure. They see the foul coating on the tongue, the loss of weight and at times peculiar mental manifestations. They can smell the foul breath and the disagreeable odor from the skin and from the bowel discharges. These they interpret as signs of physical deterioration and degeneration. These manifestations indicate that the entire body is cleansing itself, throwing out impurities that have accumulated, because the system has had so much work to do that it has lacked the power to be self-cleansing. Nothing is needed to prove this fact except to continue the fast until the odors disappear and the tongue becomes clean.
The bad odors given off by the body resemble the odors in severe fevers with much wasting, and hence they alarm those who have had little or no experience with protracted fasts. These odors are often bad at the end of about one week of fasting, though there is no fixed period for their appearance. They should cause no alarm for they simply indicate that the body is cleansing itself, and that is exactly what is desired. Under proper conditions I have neither seen nor heard of a fatality coming from a short fast. Those who are in such physical shape that they will die if fasted from five to ten days would die if they were fed.
Another symptom that may alarm the attendant is the lowered blood pressure. This is natural and should cause no anxiety. Eating and drinking keep the blood pressure up. When the food intake is decreased, the blood pressure is reduced. When the food intake is stopped, the blood pressure is still further reduced. This fact should give the intelligent healer the hint to reduce the food intake in such abnormal conditions as arteriosclerosis and apoplexy. During prolonged fasts the blood pressure generally becomes quite low.
Some fasting people can continue with light work, and when they are able to do this, it is best, for it keeps them from thinking about themselves all the time. If there is a lack of energy, dispense with work and vigorous exercise. In acute diseases there is no choice. One is compelled to cease laboring. In chronic diseases it depends on the patient and the adviser.
Dismiss fear from the mind and do not discuss the fast or any of the symptoms with anyone except the adviser. It is best not to tell any outsiders about the fast, for the public has some queer ideas on the subject. If you are afraid, or if you have to fight with neighbors, friends, relatives, or perhaps with the health authorities, as sometimes happens, it is better not to take the fast.
Drink all the water desired. At first the more one drinks the more quickly the system cleanses itself. A glass of water every hour during the day, or even every half hour is all right. The water may be warm or cold, but it should not be ice-cold nor should it be hot. Both extremes produce irritation.
