What can I eat before a glucose test?

Hi mamas! 
I'll be 24 weeks when I have my 1 hour glucose test on Friday and there's no specific instructions on if I should fast or not. Unfortunately for me, my glucose test is at 12:15 in the afternoon so I need to eat something. 
I did some research and it says to eat a lot of protein and stay away from sugars but I've also read a lot of things that say to eat as you normally do and don't try to trick the rest. 
Has anyone taken it recently at Quest Diagnostics (where they're sending me) and know if fasting is required? If so, for how long? And what should I eat/drink before?
