Carnie Wilson may have lost 20 dress sizes following gastric bypass surgery, but the new mom picked up some pounds when she got pregnant with daughter Lola. She has lost 65 of the pounds she gained, but with 40 left to get rid off, Carnie seeks professional help by being on the fourth season of "Celebrity Fit Club," Entertainment Tonight reported Tuesday. "I may be this person known as the spokesperson for gastric bypass, but I have struggles and challenges too. I'm only human," said Wilson. "It took me nine months to lose 15 pounds," she said. "That was really frustrating. Then you just want to give up. It was one step forward and two steps back." When she was approached about doing VH1's "Celebrity Fit Club," she decided it might be the answer to her weight struggle.
