I did specify a doctor who isn't earning money from the stuff you have to buy... and completely replacing ALL food with the substitutes sounds totally over-the-top to me, no matter what the regulations are... The counselling and behaviour therapy is however a good thing, and I suppose better than nothing, especially in such a drastic situation... Be very careful in the reintroduction phase, totally cutting out any "real" food at all will make this much worse than a normal diet, and that's very risky even at the best of times. Good luck, whatever !
