Oprah Winfrey is expanding her TV empire by launching a new rehab TV series, about people who suffer from compulsive eating disorders.

Inside Rehab will air on the TV queen's new U.S. cable network, OWN: The Oprah Winfrey Network.

The one-hour documentary series will follow one group of patients as they undergo an intensive 42-day recovery program.

Network executives say the programme "gives viewers a rare look inside an eating disorder treatment facility where patients face their demons and struggle to come to terms with what’s behind the food. This is what happens after the intervention"

The OWN network is projected to launch in 2011.
