You're standing in line at the grocery store, and there she is: A woman with an amazing body (she's undoubtedly wearing yoga clothes -- maybe she even has a mat strapped to her back), glowing skin, and a cart full of vegetables. You contemplate hiding your pint of Ben & Jerry's behind an "Us Weekly" as you're overcome with guilt and the realization that healthy grocery shopping has never been your forté.

Sound familiar? Whether you're on a diet or just trying to eat healthier, the grocery store can be an intimidating place, rife with temptations. However, there are certain women -- namely slim women -- who seem to float through the aisles picking up the ripest fruits and most pristine-looking vegetables. They grab a piece of wild salmon, maybe a jar of almond butter, and they're on their way.

Skip ahead to learn the healthy grocery shopping tricks of slim women.

These superhuman shoppers have a secret: a set of healthy grocery shopping guidelines they follow no matter what. While the key rule used to be "focus on the perimeter" (meaning you should shop the produce, meat, fish, and dairy sections to get the healthiest, freshest ingredients), that's no longer the ultimate rule to shop by. "I love grocery shopping," says celebrity yoga and fitness instructor Kristin McGee (who epitomizes the gorgeous shopper described above). "But it's important to go with a plan -- supermarkets are getting so tricky."

McGee and women like her have mastered the art of healthy grocery shopping. Follow their rules and you won't even want to pick up the Chunky Monkey.
