I don't have just one. it changes from time to time. I used to be able to eat small amounts of peanut butter, but lately I've wanted to eat the whole jar so I have to stay away.
Any kind of crusty, yeasty bread turns in the human vacuum cleaner. Dense whole grain breads like Ezekial and whole rye don't set me off. Also this week, I seemed very successful with eating lentils on torillas. (successful in that I lost this week)
And also lately, potato chips. There is one particular kind that I crave. When I buy some, I eat the whole bag in one sitting--even the big bag!
After eating the whole bag, I turn into the human vacuum cleaner. if I DON'T give in and buy the bag, I eat everything in sight trying to take my mind off the chips. They are EVIL! But the last week or so, I've been doing OK. No chips! No binges! Repeat after me: salty fat bombs, salty fat bombs, salty fat bombs
