I have read several books on fasting but I preferred it to the others. It informs and makes the synthesis of certain books and research, while remaining simple and affordable to anyone not initiated into fasting. It reads easily and even offers some entertaining anecdotes through the experience of a jeûneuse, making it more fun than just reading the manual fasting. There is some repetition but I have not been embarrassed in the sense that it helps to retain certain information and be well prepared before embarking on a first fasting. It is a book that prepares for a total fast, not as a diet are actually some books on fasting (diet fruit juice, broth, 1 meal per day ...)
