This book provides numerous anecdotal examples from the mid-1900's of people who have recovered from various illnesses and obesity while fasting on juice. It gives some guidelines or "to-dos" for juice fasting and different methods and settings for doing a fast. It discusses the vital importance of exercise and rest. It does not incorporate nutritional information, scientific breakthroughs or medical insights from the past three decades. It does not give a lot of detail about potential risks of fasting for different people. The reader will need to balance the directives of the book with current health information and her knowledge of her own body.

The book is rather short. As the title indicates, it is a guide for fasting. It is not a guide for healthy eating when not fasting. There is some information in there about that, but if more nutritional detail is desired, the reader will have to look elsewhere.

The author's writing style is very enthusiastic and easy to read. It is clear that he had a passion for the subject matter and believed in the power of juice fasting.
