I play the "Borderline high blood sugar card". If they persist, I tell them that my doctor says I'm at risk for diabetes (we ALL are, if we continue to eat this garbage), and that I'm only allotted a certain # of carbs per day and I have a big dinner planned tonight (or lunch, or whatever is convenient) that will use up all my carbs. I then stare longingly at the food they want me to eat and say, "Oh my gosh, I SO wish I could eat that. You enjoy!"
I did this just today with cupcakes. They looked amazing, but I brought up the blood sugar issue, and it was quickly dismissed.
