Christina Applegate's Fried Cheese and Cupcake Pregnancy Diet

(CBS) Pregnant Christina Applegate, 38, told late-night TV host George Lopez that she scarfed down red velvet cupcakes and fried cheese soon before going on air last week.

Applegate, most famous for her role as the pretty-but-ditzy working-class daughter in the long-running sitcom "Married With Children," appeared healthy and vibrant, but doctors warn that pregnant women shouldn't follow her lead.

Research shows that overweight pregnant women significantly increase their chances of producing a baby who will grow into an overweight child.

A recent study shows that children born to overweight mothers were 1.4 to twice as likely to be overweight compared to their peers who had mothers who were at healthy weights.

There goes the ice cream and pickles.

"This study adds to the body of current research that points out how important it is for women of childbearing age to develop lifestyle habits that promote a healthy weight before they become pregnant," study co-author Panagiota Kitsantas, an associate professor in the department of global and community health at Mason College of Health and Human Services, said in a George Mason University news release.

The study was published in the European Journal of Pediatrics.
