That's what bugs me about the idea of cheat days when people talk about wanting to eat better. Six days isn't long enough for most people's tastes to change. It just sets up a cycle where they're miserable with the food they're eating most of the week instead of giving their body a chance to adapt to the new tastes and textures. It really isn't any different than trying to beat a drug addiction by just using it every other day instead of every day.
