I strongly recommend that you read this book:
You don't need to buy all the other stuff...the book has all the info you need. It's worked for me. I follow it about 85% of the time... I was diagnosed with Type II diabetes last October. I was on metformin for 3 months, but the Eat to Live regimen took my H1b from 11 down to 4.6, and I was immediately taken off metformin. I've dropped 30 lbs, and I've never eaten so much in my life. I feel great!
Time for my Saturday walk (6-9 miles), it'll wipe out my trangressions of this morning, i.e. a couple bowls of cereal...lol
BTW, my next goal is to get off Crestor. That will be a tougher nut to crack, I think.
