If you think Whitney Port is a typical food-phobic fashion chick — think again. Her attitude toward her body, fitness and diet are refreshingly healthy. The star of MTV’s The City tells OK! that she’s not one to go hungry. “I’m a really big snacker!” Her favorite snacks: popcorn and frozen yogurt.

“If I don’t constantly have energy from food then I get in a bad mood.”  Whitney, 25, even allows herself one day a week — usually Sundays — to eat “what I want… Everything in moderation,” she says.

“There are times when I’ll look at someone and say, ‘I totally wish I looked like that,’” but Whitney swears she doesn’t stress about being a certain size.

To find out what Whitney does in the gym to maintain her lean physique, buy a copy of the new issue of OK! on stands everywhere! She is also  featured in our What I Ate Today weekly diet special where she tells us exactly what she  ate all day!
