Media megastar and Mississippi native Oprah Winfrey was at MSU's Riley Center in Meridian late last week to tape a portion of her daily television show that airs today. Meridian was chosen to launch the Best Life Challenge 2008, a national weight-loss and fitness campaign organized by her personal trainer Bob Greene (r). The city is being praised for its own version of the better-health program called "Just Lose It." A federal report last year listed Mississippi as No. 1 in obesity.
