William T. Jarvis, Ph.D.

Fasting involves voluntary total food deprivation (water only or distilled water only), juice-fasting which permits fruit juices or distilled water and lemon juice. Fasting has a long history as a symbolic demonstration of religious devotion, act of protest, or commitment to a political cause. Various so-called "natural health" or "hygienic" practitioners advocate fasting to "cleanse the body" or as a cure-all. Herbert Shelton, advocate of "natural hygiene"[1] and originator of the erroneous idea of "food combining" popularized by the best-selling pseudonutrition book Fit For Life, was an influential advocate of fasting.
