The only exception to this would be a person who has already significantly detoxified and healed their body by previous fasting, or the rare soul that has gone from birth through adulthood enjoying extraordinarily good nutrition and without experiencing the stressors of improper digestion. When one experienced faster I know finds himself getting "run down" or catching a cold, he quits eating until he feels really well. Instead of feeling weak as most fasters do, as each of the first four or five days of water fasting pass, he experiences a resurgence of more and more energy. On the first fasting day he would usually feel rotten, which was why he started fasting in the first place. On the second fasting day he'd feel more alert and catch up on his paper work. By his third day on only water he would be out doing hard physical chores like cutting the grass, splitting wood or weeding his vegetable garden. Day four would also be an energetic one, but if the fast extended beyond that, lowering blood sugar would begin to make him tired and he'd feel forced to begin laying down. After a day of water fasting the average person's blood sugar level naturally drops; making a faster feel somewhat tired and "spacey," so a typical faster usually begins to spend much more time resting, further reducing the amount of energy being expended on moving the body around, serendipitously redirecting even more of the body's energy budget toward healing. By the end of five or six days on water, I estimate that from 40 to 50 percent of the body's available energy is being used for healing, repair and detoxification. The amount of work that a fasting body's own healing energy can do and what it feels like to be there when it is happening is incredible. But you can't know it if you haven't felt it. So hardly anyone in our present culture knows. As I mentioned in the first chapter, at Great Oaks School I apprenticed myself to the traveling masters of virtually every system of natural healing that existed during the '70s. I observed every one of them at work and tried most of them on my clients. After all that I can say with experience that I am not aware of any other healing tool that can be so effective as the fast.
