NEW YORK -- Chowdown champ Joey Chestnut has done it again -- this time proving he's a pizza powerhouse.

Joey "Jaws" Chestnut

He downed 45 slices in 10 minutes Sunday to win the first Famous Famiglia World Pizza Eating Championship in New York's Times Square.

The 24-year-old from San Jose, Calif., says he fasted for more than a day to prepare.

He folded and squeezed the slices to make them easier to swallow.

Chestnut became a competitive-eating celebrity when he won Coney Island's July Fourth hot-dog eating contest in 2007. He took the title again this summer by gulping down 59 dogs in 10 minutes.

He won a contest in Tennessee last month by wolfing down 93 Krystal hamburgers in 8 minutes.
