Isla Fisher Shows Off Post-Baby Body, Talks Diet (PHOTOS)

A new baby means lots of joy -- and a few less snacks.

Isla Fisher, who gave birth to her second daughter six months ago, has had to change up her diet a bit to get back to her famous Hollywood figure. So she says.

Speaking to Us Weekly, Fisher said, "I used to say that I could eat anything I wanted and it was true and now I can tell you that I can't eat whatever I want."

Fisher, who is married to comedian and actor Sacha Baron Cohen, hasn't released the name of her new daughter; the pair has a three year old daughter named Olive. After Olive's birth, Fisher seemed to have little trouble getting back to her old body, as you can see from these photos.

Here's how Fisher looks post-birth the second time around, at the premiere of her new film, "Rango." Eating fewer snacks, it seems, has done the trick.
