The current book is purely empirical. It contains a historical summary of more than five decades of clinical experience of the first two authors, as well as advice on how to handle certain clinical problems within the context of a lifestyle-clinic with focus on water-only fasting. The book however is not to be regarded as a general recommendation to follow that approach, nor does it reflect current clinical practice of all authors.   About the Authors Alec Burton received his degrees in Chiropractic and Osteopathy from the Northern College of Chiropractic in Manchester and the Osteopathic College in London.
