Earlier in the month, Bob and Oprah launched their Best Life Challenge 2008 to inspire and motivate millions of Americans to lose weight and get fit for life. Now, Bob is traveling the country along with registered dietitian Zonya Foco to spread his get-healthy message and encourage people to sign the Best Life Contract. "What you're signing is a commitment to live a healthier life—for sure in 2008, but my dream is that you continue to do that for the rest of your life," Bob says.
