Carnie Wilson's Weight Struggle

In 1999, Carnie Wilson famously underwent gastric bypass surgery to cut 150 lbs. off her 300-lb. frame. Her struggle with her weight wasn't over, though, as she gained back the pounds carrying daughter Lola, now 2. But after a stint on VH1's Celebrity Fit Club, Carnie shed another 22 lbs. That was two years ago. Now, a month away from her 40th birthday, Carnie weighs 208 lbs. and wears a size 16. Opening up to OK!, the singer says she has hit "rock bottom" with her weight.

"Everyone can see that I'm bigger, but I cannot hibernate," she tells OK!. "I've never lied or been dishonest about what's going on in my life. Even all these years later, having had such a great weight-loss story, being back in this place is so familiar. And it hurts. I don't want to feel this way anymore. It doesn't feel good when you have to struggle to get your pants on."

The source of her tremendous weight gain is snacking. Since having her daughter, the former Wilson Phillips star says she turned all her focus on her little girl, leaving little to no attention to her weight or diet.

"I had anxiety, started snacking and gained it all back and more," she says. "I have a weakness when it comes to snacking. For me, it's a tortilla with cheese, popcorn and graham crackers, all in one night."

Now Carnie is determined to get back into shape -- and get pregnant.

"I'd like to lose 45 to 50 pounds and then try to get pregnant again. I know I will do it! I don't consider myself a failure. I just got off track."
