When it comes to staying healthy, Ashley Greene does it the old-fashioned way. Staying active and watching what she eats!

The 27-year-old actress wows on the November cover of Women's Health, flaunting her toned figure in a blue mini-dress. In the magazine, Greene dishes on how she maintains good nutrition and an active lifestyle, despite a guilty pleasure snack every once in a while.

"I grew up in Jacksonville, Fla., on the beach we always had water around us. I actually grew up the first 14 years of my life in Middleburg, Fla., and we grew up on dirt roads and my dad built our house," explained Greene. "My neighbor had horses. I got to have a little bit of that lifestyle and enjoy nature. We went outside to entertain ourselves and play. I was selling mud pies and playing football with my brother."

The "Twilight" actress acknowledged that she learned to love the outdoors at an early age.

"My brother is a year and a half older, so I was a tomboy as a result of us being so close. It's transferred over to my adult life. I think being athletic as a child and always being competitive in sports and martial arts definitely transferred over to my adult life. Now for me it really is this kind of lifestyle choice. I feel like I really need to be outside. I need to have nature. We go up to Big Bear all the time because it's such a different world than it is being in the midst of everything."

As for her diet, Greene has an impressive amount of self-control but admit to one not so healthy weakness.

"I try to eat relatively clean. That being said, part of the benefit of being active is that I kind of can eat whatever I want from time to time. Before photo shoots, I have to cut back on the sodium. I'm not really a sweets person, but I love pickles. They're always sitting in my fridge," said Greene.

"I was talking to my friend, I was like, 'I don't have a problem with anything else, but I really just want to eat one of those pickles and I can't do it.' I'm probably going to have one tonight," the actress told the mag.

Aside from a good kosher dill, Greene confessed to a few more favorite treats. "Pinkberry has this new peach flavor. I'm pretty sure I ate the whole tub of it," she said. "And Cheese-It's. I can't keep them in the house because I love them."
