How Did Jessica Simpson Lose Her Baby Weight?

Jessica Simpson is sharing the weight loss secrets that helped her slim down after giving birth for the second time in two years.

The style maven and fiance Eric Johnson welcomed daughter Maxwell in May 2012 and son Ace in June 2013. In a new interview with USA Today, the Weight Watchers spokeswoman said she used the program’s two-week Simple Start plan to get back on track following Ace’s arrival.

Simpson, who gained more than 70 pounds during her first pregnancy, vowed to do things differently the second time around by staying active and eating healthy.

“With Maxwell, I vegged out and laid around. I knew I didn’t have to watch what I was eating for the first time in my life. I kind of let loose and I gained a lot…”

Jessica says she lost more than 50 pounds on Weight Watchers after Maxwell was born. So how does she keep the weight off?

Well, for starters, The Dukes of Hazzards star has a chef to prepare healthy family meals. The sometimes singer also works out four days a week with personal trainer Harley Pasternak (he also trains Rihanna). And, of course, there’s just being a mom:

“With both kids I’m running up and down my stairs a million times. Kids can keep your metabolism going.”

With a healthier lifestyle has come clarity about criticism, she says:

“It does get old having people harping on how much you weigh or your body after pregnancy. I need to feel comfortable in my own skin. People are going to pick me apart no matter what I do. I’m always going to have critics out there who will make a story out of something.”
