Fasts, commonly understood as periods of complete or partial abstinence from food, is a practice that has been observed by individuals and communities across the world for centuries. There are various synonymous terms used to describe different types and durations of fasts. For instance, intermittent fasting, an increasingly popular health trend, refers to a pattern of eating that cycles between fasting and non-fasting periods. Another common term is dry fasting, which involves abstaining from both food and water for a set amount of time. Other synonyms for fasts include juice cleansing, water fasting, spiritual fasting, and selective fasting, each of which may vary in duration, dietary restrictions, and underlying reasons for practice.
