PHOTOS: Jon Gosselin... Health Nut?

Jon Gosselin loaded up on low-calorie fare while shopping alone at a Reading, Pennsylvania grocery store Monday, and RadarOnline.com has the shots for you.

The divorced reality TV dad's cart was full of products like Diet Coke, Healthy Choice TV dinners and Jiffy Pop butter-flavored popcorn (cut the guy some slack, he's trying.)

Perhaps Gosselin is spurred on seeing his ex-wife Kate display a toned, tan figure on Dancing With The Stars. Or maybe he's trying to avoid being a shoo-in for the next cycle of Celebrity Fit Club.
