Hi Charlotte
I have the new Inch Loss Plan, and to be quite frank I am not very impressed. She sets out daily menus for you to follow, but you can interchangesay a lunch from the Monday menu if you did not like the Thursday menu. It's not very veggie friendly and there is very little fish, so if you are a big meat eater you are well away. I have, however, found her TV channel a god send as Dean does tell you if you can change any of the meat menus for quorn or fish. If it was me I would not waste your money and just keep to the Hip and Thigh. I am assuming you mean the new one. I am, I must admit an avid fan of the old one, but most of her recipes seem to be repeated in most of her books.
Whichever diet you choose, good luck
April
