(PEOPLE.com) -- The former Sports Illustrated cover girl is back in modeling shape -- but not because she wants to retake the catwalk.

"I switched up my unhealthy eating habits for healthier eating habits, and I haven't had a tummy attack since December '08," she said.

Banks is now revealing how she lost almost 30 lbs. since her famous "Kiss My Fat Ass" incident in early 2007.

"I feel good about my curves and my imperfections -- my booty, my boobs, my thighs -- I embrace it all," she said. "Now I really can say ... kiss my fat -- and still fat -- ass."

Nutritionist Bauer suggest that to "get your shape in shape" like Banks, the first step is to keep a record of what you eat. "You have to write everything down," she said, explaining that this will let you identify what foods make you feel good and which do not.
