Welcome to the forum Vicky. If you're looking for a plan have you thought about joining weight watchers or slimming world? Or maybe buying or borrowing a GI book from the library?
Welcome, Vicky!
There are all kinds of great sub-forums here... Veggie suggested some, and there's also the South Beach diet, etc. http://www.3fatchicks.com/forum/index.php
Take a good look around... I'm sure you'll find a plan that you're comfortable with.
Good luck!
