The problem with fasting before the 1 hour test is that it doesn't give accurate results. You will basically be skewing the results incorrectly if you fast and you aren't supposed to be.
I should have clarified my own post. I was told by the nurse practitioner that what I did or did not eat or drink would not affect my results. She said some doctors even recommend having patients fast for four hours before the test. Also, when I say I "basically fasted," I should have not been so casual in using that term. I meant that I hadn't eaten much that morning (mine was in the morning) except a handful of Pringles and two vitamin waters (not the zero calorie ones).
People who have these one hour glucose tests first thing in the morning are not expected to have already eaten lunch-sized meal.
Anyway, I ended up passing with a 102, so I was well in the clear.
