Give Ashley Greene credit for this at least:

When asked how she stayed in shape, the actress didn't pull a Kim Kardashian and start to shill for a dangerous weight loss product.

Still, the Twilight Saga star's publicist actually nudged his client after she gave the following response to Us Weekly:

"It was really easy. We were working 12 hours a day, so it didn't leave too much time to eat."

Kids, don't try that diet at home.

Greene added that the (hot!) cast had a personal trainer on set that put each star through four hours of training per day.

To stay in shape these days, she also told the magazine she does Pilates about six days per week.

"I do it early in the morning. It wakes you up, and it's kind of refreshing," she said. "And that is basically it. Sometimes cardio. I am not a big weight person because when I do weights I build muscle mass."

Much to the delight of women everywhere, Taylor Lautner can vouch for that. Can he ever!
