You have a better chance of passing if you eat veggies and protein. Toast isn't a great idea because carbs are sugar. So no bread or cereal no milk or yogurt. Eat eggs with cheese sausage stuff like that
Eggs and toast but make sure you eat i didnt feel like eating that day was a little nauseous and failed the test and had to do the 3hr test
My doctor told me to eat my regular breakfast which consists of eggs and sausage so the test could accurately examine my levels.
Plain toast is ok, i didnt eat before mine since it was early
