Oprah and Bob Greene launch Best Life Weight Loss Challenge tomorrow

Oprah -- who I like to think of as one of the great ombudspeople of healthy living (because let's be real here, you can chide yourself for liqui-diets and martinis all you want, but eventually all the stuff your on-call personal trainer's beating into your head sinks in, right?) -- is teaming up for a weight loss challenge that premieres tomorrow.

Will this be just another televised scale-fest? Or will Oprah and her team, including fitness expert Bob Greene (*love*) inspire the audience à la Biggest Loser and Dr. Phil's Ultimate Weight Loss Challenge?

If you'd like a sneak peek, check out the Best Life Diet site, with articles, a hunger scale, fitness ideas and inspiration, recipes (mmmm....sugar-crusted salmon with grapefruit. I'm in!) and Oprah's own food diary, and a place to share your story and find community (a hallmark of the Oprah-marketing machine and a great way to stay connected and committed if you like this idea).

Tune in and see for yourself! I will be watching and then waiting to hear what you think: Is this just another show or is Oprah's newest weight loss endeavor motivation for you?
