I've tried breaking my potato chip habit with "lower calorie" popcorn puffs, but like Kathyp says, I would end up eating the whole bag at one time! My instinct is the higher the Glycemic Index number of something, the faster you're going to finish the bag off :-D
I've tried eating the frozen potato quarters seasoned with olive oil and herbs. They're about as fulfilling as the chips, but they just take longer to wait for. Who has the time to wait in today's society :-D
