This publication is the first comprehensive and authorized chronicle of the Buchinger Wilhelmi family. In unprecedented detail and openness, both the family history and details of the emergence of modern therapeutic fasting are presented in an informative and entertaining way. Modern therapeutic fasting had a shadowy existence at the beginning of its application by Otto Buchinger. Not least due to years of scientific research by the Buchinger Wilhelmi family, it has become an indispensable part of modern lifestyle. At its two locations in Überlingen (Germany) and Marbella (Spain), Buchinger Wilhelmi offers its guests an internationally recognized therapy and fasting concept with the aim of bringing body and soul into harmony. The book provides an instructive introduction to the company's history and therapy components. Large-format photographs (photographed by Olaf Heine, among others) look behind the scenes and provide unpublished insights into the extraordinary world of Buchinger Wilhelmi.
