The authors, after we made a small reminder of the history of fasting, we describe the effects of fasting on the body, the preparation phase, the period of fasting and refeeding phase. Also included is complementary holistic means that can be practiced during a fast such as bowel enemas (or irrigation), massages, sunbathing, emotions, Bach flowers, Amaroli (or urine therapy).
A chapter is also dedicated to those who feed on light, this chapter may seem inappropriate, but I think it has a place insofar as these people do not feed at all, a bit like a fast, except that the Fasting does not last. This is an interesting topic even if it is highly contested, and it is difficult to believe, in the meantime, we talk more and more and there was even a documentary that came out in the cinema there a few months on this: "Light."
