Jessica Biel has revealed the secret behind her slender frame – besides healthy diet and regular workout sessions, she sends half of her meal back while in a restaurant. 

The stunner makes sure she doesn't overdo her portion size when she eats out, reports Contactmusic.

She says, "You have to find a balance, especially with what you eat. I don't live by the idea that you can't allow yourself a treat.

"I say, ''Eat things you like, but eat them in smaller portions''. I always cut things in half and send them back.  “I'm not perfect, I don't always do those things, but that's the goal."
