Breastfeeding, a great workout: Mila Kunis

Actress Mila Kunis, who welcomed daughter Wyatt Isabelle in October, credits the breastfeeding routine for her post-baby body.

During an interview on "The Late Late Show", the host Craig Ferguson complimented the actress on her svelte shape, reports people.com.

To that, the 31-year-old said: "Breastfeeding is a great workout."

To keep her energy up, Kunis said she just "eats a lot - that's what keeps me going through the day".
