Froma purelyphysiological standpoint, "fasting" can refer to a person's metabolic state after not eatingovernight (see "Breakfast"), or it can refer to the metabolic state achieved after completedigestion and absorption of a meal.
In the fasting state, metabolic changes begin after a meal is digested (typically 3-5 hours after eating). A diagnostic fast is a period of fasting lasting 1 to 100 hours (depending on age) that is done under medical supervision to aid in the investigation of a health complication, most commonly hypoglycaemia. Many people fast before a medical procedure or check-up, such as a colonoscopy or surgery, or before certain medical tests. Intermittent fasting is a weight loss technique that is sometimes used.
