Fasting has deep roots in human history. Ancient civilizations, including the Greeks, Egyptians, and Romans, practiced fasting for both spiritual and health reasons. Philosophers like Hippocrates and Plato recognized the therapeutic potential of fasting, and religious traditions across the world, from Islam's Ramadan to Christianity's Lent, have long acknowledged its significance. In recent decades, modern science has begun to validate these age-old practices, revealing the remarkable benefits of fasting for physical and mental well-being.
