Molly Ringwald's dieting rule of thumb

Molly Ringwald, 42, turned out at the Oscars in a slender, Trojan-style gown that made the recent birth of her twins seem eons away.

But the actress laid her fine form to working out and a simple rule of thumb. Always choose something green.

She told People Magazine: "I try to make sure that I eat something green. I think that's just a really good rule of thumb. I love all different kinds of vegetables, but the green ones are generally the best for you and the best for your diet."
