Saturday's Best Bets on TV

"Childhood Obesity: Danger Zone" (9 p.m., Food Network): This special addresses a growing epidemic that grips more than 12 million U.S. children and teenagers. In the past 40 years, childhood obesity has quadrupled, affecting 17 percent of the youth population with what could be the silent killer of a new generation: According to the program, half of the youngsters diagnosed with obesity suffer from hypertension, gastrointestinal problems and other health threats. Besides highlighting the problem, the hourlong special also shows how parents can serve as agents of change in their child's life, and what communities can do at a public health level. Produced by Al Roker.
"This Film Is Not Yet Rated" (11 p.m., Independent Film Channel): Directed by Kirby Dick, the acclaimed documentary "This Film Is Not Yet Rated" asks whether Hollywood movies and independent films are rated equally for comparable content; whether sexual content in gay-themed movies are given harsher ratings penalties than their heterosexual counterparts; whether it makes sense that extreme violence is treated more forgivingly than extreme sexuality. The film -- which in part is about Dick's own efforts to get a rating for this film -- has its television premiere on the Independent Film Channel.
"Independent Lens: Race to Extinction" (11 p.m., PBS): The stories of two death row inmates, Robert Tarver in Alabama and Madison Hobley in Chicago, form the heart of this documentary, which looks at the elements of race, justice and the media that can surround the path to execution.
