At 208 pounds and a size 16, singer Carnie Wilson has revealed in a recent interview details about her gastric bypass surgery and how she is struggling to lose weight – again.

What was your biggest diet downfall before gastric bypass surgery? Doughnuts. You don’t get to 300 pounds by eating diet pie. Ice cream. I would go through McDonalds drive-throughs and have a Big Mac, Super Size fries, a 20-piece Chicken McNuggets, a pie and a shake.

That would be one meal for me – horrid! Now, if I start my morning out with a piece of toast, I’m doomed for the day. It’s like, give me carbs! Surgery or no surgery, I’ve gotten to know who I am with food and how my body reacts.

Any regrets about having the gastric bypass? No, it was the best thing I ever did. If I didn’t have the surgery, I’d probably be dead. My liver was enlarged; it was toxic. I had sleep apnea – I was waking up choking 10 times a night. My cholesterol and blood pressure were high.

I was pre-diabetic and had circulation problems, slipped disks in my back, acne and chronic headaches. The surgery taught me to be accountable for what I put in my mouth. The truth is that the weight loss happened so fast that I couldn’t absorb it. Everyone was watching and there was so much pressure.

What was life like after the surgery? In 2003, I was drinking heavily. Maybe I couldn’t handle feeling that great. I remember driving down Coldwater Canyon [in California] and thinking I could just turn this wheel and drive right off a cliff. In 2004, I reached a bad low and stopped drinking cold turkey. Thirteen days before I got pregnant, I got sober.

Would you ever have plastic surgery? One day, I’d love to have the skin on my arms removed. It just hangs there. [via]
