The parent company of Animal Planet, the Discovery Channel and other major cable television channels calculates it saved $5 million since opening a corporate wellness center with a clinic and other wellness programs five years ago. About $4 million of that is from lower medical claim costs. As Democratic lawmakers in Washington inch ahead with plans to overhaul the U.S. healthcare system, companies like Discovery are striking out on their own -- whether through on-site doctors or diet plans -- to rein in soaring costs in a nation where employers still pay for the bulk of medical care.
