I read and enjoyed the India Knight book; very funny and I liked the fact that they have been there and eaten the scone. They are not skinny food fascists and are understanding of cravings. But.....I cannot and will not give up caffeine as I could see no good reason in the book for doing so. Coffee is my one vice ( apart from fattening food, obviously), I don't smoke, hardly drink alcohol, just the odd glass when out for dinner, and I take my coffee black. I love a good pot of coffee, fresh ground and have read that the process involved in de-caffeinating coffee and tea is quite toxic, rather like people eating low fat petroleum by-products masquerading as butter like spread, rather than have the real thing. So, shall cut out bread, pasta, rice, vegetables grown below ground ( higher carb content) and see how I get on.
