'''Fasting''' is the willful refrainment from [[eating]] and sometimes [[drinking]] (see [[Water fasting]] and [[Juice fasting]]). From a purely [[physiology|physiological]] context, "fasting" may refer to the [[metabolism|metabolic]] status of a person who has not eaten overnight (see the "[[Breakfast]]"), or to the metabolic state achieved after complete [[digestion]] and [[Nutrient|absorption]] of a [[meal]].<ref>{{Cite web|title=fasting {{!}} Definition, Description, Types, Benefits, & Facts|url=https://www.britannica.com/topic/fasting|access-date=2021-10-28|website=Encyclopedia Britannica|language=en}}</ref> Several metabolic adjustments occur during fasting. Some [[diagnostic test]]s are used to determine a fasting state. For example, a person is assumed to be fasting once 8–12 hours have elapsed since the last meal. Metabolic changes of the fasting state begin after absorption of a meal (typically 3–5 hours after eating).

A [[diagnostic fast]] refers to prolonged fasting from 1 to 100 hours (depending on age) conducted under observation to facilitate the investigation of a health complication, usually [[hypoglycemia]]. Many people may also fast as part of a medical procedure or a check-up, such as preceding a [[colonoscopy]] or [[surgery]], or prior to certain medical tests. [[Intermittent fasting]] is a technique sometimes used for [[weight loss]] that incorporates regular fasting into a person's dietary schedule. Fasting may also be part of a [[#Religious views|religious ritual]], often associated with specifically scheduled fast days, as [[#Religious views|determined by the religion]].
