OWN: The Oprah Winfrey Network has added another new unscripted series to its primetime lineup: Inside Rehab. The 8-episode hourlong docu-series, from Harpo Studios and Tijuana Entertainment’s Troy Searer and John Foy (Obsessed), follows eating disorder patients at a treatment facility as they undergo an intensive 42-day recovery program. The announcement comes a day after E! said it has ordered “What’s Eating You?,” a six-episode docu-series about eating disorders to air in the fall. OWN is set to launch in January.
