The premise of "16 and Pregnant" is disturbing enough, but this week it hit an all new low. Kayla is pregnant -- and anorexic. The teen constantly covers her belly in public because she feels "fat, not pregnant," she says. "I hate the way it feels."

"Is it possible to lose weight during pregnancy and have that be ok?" she asks her mom, Deb.
