Looks like Kate Gosselin isn't the only one shaping up. Jon Gosselin was photographed on the beach looking much slimmer than he did earlier this year. Gosselin's beer belly even appears to be more toned! In a new InTouch Weekly interview given exclusively to PopEater, his friends reveal what's behind Jon's dramatic weight loss.

"Jon's made time for himself," Gosselin's friend tells the magazine. "Jon's own dad never took care of himself and died at an early age, so Jon is doing whatever he can to ensure he'll be around for his kids as long as possible."
