What we call fasting blood sugar or blood glucose levels is usually done six to eight hours after the last meal. So it's most commonly done before breakfast in the morning; and the normal range there is 70 to 100 milligrams per deciliter. Now when you eat a meal, blood sugar generally rises and in a normal individual it usually does not get above a 135 to 140 milligrams per deciliter. So there is a fairly narrow range of blood sugar throughout the entire day.
