Fasting

Willing abstinence from, or reduced consumption of, food and/or drink

Fasting is the act of refraining from eating, and sometimes drinking. However, from a physiological context, "fasting" may refer to the metabolic status of a person who has not eaten overnight (before "breakfast"), or to the metabolic state achieved after complete digestion and absorption of a meal. Metabolic changes in the fasting state begin after absorption of a meal (typically 3–5 hours after eating).
