"It Mom", Gwyneth dishes about her vices and losing weight in V Magazine:

"I put on 40 pounds with Moses. And I found it really hard to loose the last 20 pounds," Paltrow, 35, admits. "I didn't mind having the big boobs. But it was the stomach roll, the back fat, and the post-pregnant butt. And it was so hard to get rid of."

She did it with by eating "organic, seasonal food that isn't processed."

"I haven't eaten meat for about fifteen years. I eat fish, a little bit of dairy – not much milk – but I love cheese," she adds. "We'll make chocolate chip cookies and eat them, but sugar makes me feel pretty bad. I have coffee and wine. I've got lots of lovely vices!" SOURCE

She must be doing something right, because her body looks amazing.
