Paleobird, my daughter moved out of the house and in with her boyfriend while I was in the States in April....(little stinker she is) so the Food Patrol ain't gettin' anywhere near my house! There'd be some sort of revolution if I had to serve tofurkey. And rightly so!
My friends' son did this last year and combined it with intense gym and really did well...but he suffered. I had a conversation with his lovely English grandma about the whole process and she said "Imagine....vegetables with NO GRAVY." That's what it was all about. Deprivation.
