Présentation de l'éditeur
Arnold Ehret was a founder of vitalism in dietetics, and pioneer of Ehretism.
This book contains the famous work "Rational Fasting" as well as additional chapters by Robert A. Miller, Fred Hirsch and "A Message to Ehretists" by Arnold Ehret.
Ehret asserted that the body was an air-gas engine, not dependent on food for energy, and that the body was not designed to utilize mucus-forming foods, offering the equation Vitality = Power − Obstruction (V = P − O) to demonstrate this.
Around 1909, Ehret engaged in a series of public lectures and fasts. Within a period of 14 months, Ehret fasted for a total of 126 days without food. He had completed a fast of 21 days, one of 24 days, one of 32 days, and one of 49 days. In 1909, he fasted in total, for 105 days.
