Written in the form of Socratic dialogue, the book of Gisbert Bölling is very enjoyable to read, and read again ... It can be opened at any page and peck few random questions! Nothing to do with the mini-guide I read there about ten years. This book is aimed at people who have already practiced fasting and those who hear about it for the first time. I recommend it to everyone as a first approach to fasting because Gisbert not only knows what he's talking about, but it is also a very good teacher who does the "play" at all. I have personally followed internship Léoux week this year, "Fasting" was my bedside book for several weeks. Read urgent for those who want to rebuild their health and see more clearly in their life! No need to go a week in a center of Fasting and hiking to begin fasting. Anyone can follow a daily or weekly fast at home thanks to this book.
