The Dan John Peanut Butter Jelly Sandwich

During Passover, you're not supposed to eat leavened bread. You can eat like matzo, which is like this sort of dry unleavened bread with even less taste. So rather than eating like peanut butter and matzo sandwiches, he just didn't eat anything. It wasn't until he started eating the peanut butter jelly sandwiches again that he would see another pound here or there. He was stunned. Never would have guessed.
