How Long Should You Fast. Your doctor may recommend a certain time period for fasting; however, the standard amount of time is about eight to 12 hours of no food before having blood drawn. Schedule your blood test for early in the morning so youâll only need to fast overnight to meet requirements. Fast for eight hours before a glucose test. The test is typically conducted in the morning while your body is still in a resting place for a more accurate reading. You must fast at least 12 hours before taking a cholesterol blood test to get an accurate reading on triglycerides.
When do I fast? Catholics, as a group, are required to fast on only two days of the year - Ash Wednesday and Good Friday. On these days, fasting means something very specific and limited. It means that one eats only one full meal in a day, with no food in-between meals.
