All the good shit's on The N this summer. Along with Queen Bees, I also really enjoyed this show.

Description:
Host Laila Ali challenges twelve out-of-shape students from rival high schools to change their bodies, their nutrition, and their attitudes. Getting healthy isn't the only incentive -- the winning school and the winning individual each take home $25,000.
I liked these kids, except for the two whiny girls. They're all so young to be so overweight. I hope they see some results.
