hey Lisa!!
it's hard to start any formal diet plan without the book but you can read the stickied threads that give a good starting reference point

Probably the first thing you should do is clean out your house, car, desk, etc of all junk food-anything processed, sugary, etc, etc give it away, throw it away, just get it out. Check out the recipe links and look for items that say wave 1. Make yourself a good grocery list and go buy whole grain breads, pastas, lots of fresh and frozen veggies, fish and chicken. Don't worry about fruits or dairy right now.
And just start eating this way til you get your book and give it the real official start. Good luck!!!
