Gestational diabetes test

Has anyone not eaten sugars/carbs the day before their GD test and had better results? Or is that even a thing?

A little background - my first pregnancy I failed the 1 hour test (super common and I’m convinced they need a better way to test🙃) anyway of course I did the 3 hour one next - passed that and all was well, I don’t mind the drink and all that but I really really do not want to have to take the 3 hour one this time. So I’ll try anything to avoid that.
