I think so, I ate a breakfast sandwich and drunk oj b4 my test and the results had my glucose high. So I had to go back and take a 3 or 4 hr test and that time I was informed not to eat.... I strongly suggest not eating b4

I didn't eat before mine, just drank water

I ate before all three of my tests. It's the 3 hour test (if u fail one hour) that you can't eat.

and alot of hot sauce

I ate before. 2 eggs and toast

My Dr told me nothing two hours prior to my appt but water

I passed by eating almonds/veggies

they always tell me no food after midnight the night before

no you just can't eat during the test.
