Your theory on eating cheeseburgers to stop craving cheeseburgers is interesting, but have to be tested, since your lean, whole wheated, no fat cheeseburger is not really junk food, it is just a healthy alternative .You may spend all this time eating the lean cheeseburger and still crave tha greasy, lard fried Mac Donald´s one...
I once tried this with pizza: Covered a Pita bread with tomato sauce ( home made, just the tomatoes), non fat cheese or ricota, oregano( sp) and after a while I was dying for a Peperonni from Pizza Hut.
Craving is very complicated and involves both emotional and chemical/neuroendocrinal aspects.
But that is just my opinion;
Your idea is original and worthy, thanks...
