I am on induction too. For me, the weight seems a bit slow in coming off, but mentally and physically i feel great and have no desire to binge on the forbidden foods. The book is well worth your time and money..its an extra reinforcement for support and understanding the whole thing helps too. i had started off with the older version (i had already had the book) and just picked up the new version this past weekend. They are basically the same, with just some new alterations.
Are you keeping a journal and gym log? (on this site). I find it extremely helpful..and with the gym log, it makes me feel good to see how much i am doing every day.
Either way..good luck to you...we can do this!
