The term for the avoidance of food is "fasting." Fasting is often undertaken for various health, spiritual, or religious reasons. In many spiritual traditions, fasting is seen as a way to purify the body, enhance self-discipline, and foster a deeper connection with one’s beliefs. It may involve partial or complete abstention from food and drink and can vary in duration from a few hours to several days. While fasting can have health benefits, such as improved metabolism and mental clarity, it is essential to approach it carefully, as prolonged fasting without medical supervision can be harmful.
