Ten-day preventive fasting is a natural and most effective way to cleanse the body and mind, unleash creative potential, balance one's state, hear the voice of intuition, and distinguish truth from falsehood. This conclusion was reached by Oleksandr Suvorov based on his own nearly eight-year experience of periodic fasting, which he practices two to three times a year.

Fasting is not only a physical but also a powerful spiritual practice that is accessible to almost everyone. In his diary-style book, Suvorov shares step-by-step recommendations with the reader on how to properly prepare for fasting, qualitatively live through each hungry day, and then come out of it correctly with maximum positive effects for mental and physical health.

The text is complemented by comments from people who practice fasting according to the author's system, and their own experiences confirm its effectiveness.
