According to Healthline, it generally takes about two to four hours for food to move from your stomach into your small intestine. The phrase 'empty stomach' isn't a fixed rule, but a guideline that varies significantly depending on the purpose, such as taking certain medications or preparing for a medical procedure. Several physiological factors, including the meal's composition and volume, affect this process.

This practice of abstaining from food or drink for a set period is used for a variety of health, spiritual, and medical reasons.
