'My Big Fat Diet Show' heading to C4

Channel 4 has commissioned a new series titled My Big Fat Diet Show.

The four-part programme, fronted by Anna Richardson, will see women of all shapes and sizes attempt to rid their Christmas excess with a two-week 'drop a dress size' diet.

Additionally, Supersize vs Superskinny - also hosted by Richardson - has been renewed for a third series comprising 11 hour-long episodes.

"In our body-obsessed world it's brilliant to have two heavy-weight series for 2010," said Channel 4's Andrew Jackson. "To welcome Supersize vs Superskinny back for a third series firmly establishes it as the ultimate body dysmorphia magazine show.

"It's double satisfying to commission the mother of all diet shows too as My Big Fat Diet Show will not only see Anna Richardson challenging the nation [to] shed those Christmas pounds, but it will explore the often extreme and fascinating ways people try to get and keep slim. They will be must-see series for the body conscious."

Both shows are due to air in January 2010 on Channel 4.
