TLC renews 'One Big Happy Family'

Network picks up 12 new episodes of the reality show

TLC has renewed its reality show "One Big Happy Family" for a super-sized second round.

The network has picked up 12 episodes of the show from RDF USA, double the first-season order.

"Obesity is an epidemic in America, so it's no surprise that viewers fell in love with the Coles family as they began their weight loss journey," said Mike Duffy, senior vp at RDF USA. "With four different perspectives, every viewer has someone they can relate to but, ultimately I think people root for them because they're refreshingly sweet, funny and honest."

The series, a docu-drama about an obese family of four that weigh a collective 1,400 pounds, premiered in December. Its second season is expected to debut in June.
