I've lost nearly 30 lbs that way. LOL! Don't knock it until you try it, besides it isn't like the burger bun adds anything to the burger itself other than empty calories.
If I want empty calories, I'll have cheesecake, not cardboard masquerading as a burger bun. LOL! But it's lent now so there probably won't be much demand for cheesecake in the near future. LOL!
