It's hard to believe that Kristin Cavallari just had a baby in August! The reality star is already showing off her slim figure and revealed to E! News at the Bing It On Halloween Costume Challenge just how she's getting back into shape so quickly.
So what's her secret?
"Breastfeeding burns 500 calories a day and I read somewhere that it's like running six miles a day. So I'd say if you can, stick with breastfeeding," she said.
The 25-year-old also confessed she was strict with her diet while pregnant.
"I'm a healthy eater in general. And I stayed that way during my pregnancy. I didn't gain more than I was supposed to and I just have a healthy lifestyle, so that helps."
The new mom to Camden Jack chatted about upcoming wedding plans as well.
Kristen is engaged to NFL star Jay Cutler, but as of now, the two have not set a wedding date.
"At first I was thinking a big wedding, and now I think we want it smaller and just close friends and family. I say that now, but it might change," she said. "I mean, I've definitely thought about everything but we haven't put wheels in motion. Like I know what colors I want, I think we know where we're going to get married but we don't have a date."
Everything's just sort of up in the air and our world is just based on Camden right now. So it depends on how that goes," she added.
