Prolonged fasts should not be taken unless necessary, and then they should be taken under the guidance of someone who has had experience and is possessed of common sense. If a person is fearful or surrounded by others who instill fear into him, he should not take a prolonged fast. The gravest danger during the fast is fear. It takes many weeks to die from lack of food, but fear is capable of killing in a few days, or even in a few hours. The healer who undertakes to direct fasts against the wishes of the patient's friends and relatives, who have more influence than he has, injures himself professionally and throws doubt upon the valuable therapeutic measure he advocates. The indications that a fast is needed are pain and fever and acute attacks of all kinds of diseases. Some of the more common diseases that call for a complete cessation of eating are: The acute stage of pneumonia, appendicitis, typhoid fever, neuralgia, sciatica, peritonitis, cold, tonsilitis, whooping cough, croup, scarlet fever, smallpox and all other eruptive diseases; colics of kidneys, liver or bowels; all acute alimentary tract disturbances, whether of the stomach or of the bowels. Sometimes it is necessary to fast in chronic diseases, especially when there is pain, but as a rule chronic diseases yield to proper hygienic and dietetic treatment without a fast, provided they are curable. Here is where many people who advocate fasting go to extremes. A fast is the quickest way out of the trouble, but it is at times very unpleasant. By taking longer time the result can be obtained by proper living and the patient is being educated while he is recovering. In chronic cases it is especially important to eat properly. The only disease of which I know that seems to be unfavorably influenced by fasting is pulmonary tuberculosis in well advanced stages. Such patients quickly lose weight and strength on a fast, and they have great difficulty in regaining either. Perhaps others have had different experiences and have made observations that do not agree with this, for cases of tuberculosis have been reported cured through fasting. It is well to bear in mind that every case that is diagnosed pulmonary tuberculosis is not tuberculosis. Many supposed-to-be cases of tuberculosis, some of them so diagnosed by most reputable specialists, are nothing more than lung irritation due to the absorption of gas and acid from the digestive tract. When the indigestion is cured, the so-called tuberculosis disappears. These are the only tubercular cases that I have seen benefited by fasts, and the improvement is both quick and sure.
