History and Evolution of Fasting
Fasting has deep historical roots and has been a part of human civilization for thousands of years. It has been practiced for religious, spiritual, and health reasons. Ancient civilizations, such as the Greeks and Romans, believed in the therapeutic benefits of fasting. In religious texts, fasting is often mentioned as a means of purification and spiritual enlightenment.
Throughout history, fasting has evolved from a spiritual practice to a scientifically recognized health regimen. The renaissance of fasting in modern times can be attributed to the rise of scientific research that supports its health benefits.
