A few I have found helpful:
The Four Day Win by Martha Beck. A book about re-training your mind. thought it a bit "new-agey" for me personally, but the ideas were intriguing.
I'm currently reading The Longevity Diet by Brian Delaney and Lisa Walford. They are advocates of calorie restriction. I'm not sure I ever want to do that--but they do know their food! They made the distinction between satiety and fullness for me which I'd never thought about before.
And I love Dr. Andrew Weil: Eight Weeks to Optimum Health. It's just so sensible and intelligent. It's the first book that really motivated me to want to become healthy.
The Best Life Diet by Bob Greene. Another one of those sensible books. I have actually based my weight loss plan on his program in this book.
There was a video a few years back by Oprah called "Make the Connection." It was fairly inspirational as well.
Thanks for this thread. I'm making library requests like crazy!
