Confronting a weighty kids' issue

Childhood obesity expert Dr. Joanna Dolgoff says parents of obese children would rather talk to their kids about anything — even sex or drugs — than weight. But ignoring it could set a child up for a lifetime of health problems and emotional heartache, she said. The issue of childhood obesity, and Dolgoff's work, will get a national airing Sunday as the new season of the NBC reality weight-loss show "The Biggest Loser" adds three kids — two 13-year-olds and a 16-year-old — to the cast.
