A lot of energy is spent during the fast in the process of eliminating accumulated poisons and toxic waste materials. It is, therefore, of utmost importance that the patients gets as much physical rest and mental relaxation as possible during the fast.
In cases of fasts in which fruit juices are taken, especially when fresh grapes, oranges or grapefruit are used exclusively, the toxic wastes enter the blood -stream rapidly, resulting in an overload of toxic matter, which affects normal bodily functions. This often results in dizzy spells, followed by diarrhoea and vomiting. If this physical reaction persists, it is advisable to discontinue the fast and take cooked vegetables containing adequate roughage such as spinach and beets until the body functioning returns to normal.
The overweight person finds it much easier to go without food. Loss of weight causes no fear and the patient's attitude makes fasting almost a pleasure. The first day's hunger pangs are perhaps the most difficult to bear.
The craving for food will, however, gradually decrease as the fast progresses. Seriously sick persons have no desire for food and fasting comes naturally to them. The simplest rule is to stop eating until the appetite returns or until one feels completely well.
