Diet and Exercise? Whhhhat?!

Diet, exercise and healthy living? The Proof is in the fact that this fab 40 is stopping traffic.



Regardless of what you may think of Jennifer Aniston, you have to admit, her body is amazing! Insiders spilled some of her secrets to maintaining her figure to Life & Style magazine.

"Whenever she wants to look her best, Jen does this strict diet so she's able to lose 5 pounds in five days," an insider on the set of The Baster... tells Life & Style. "She did it during her past few films and doesn't find it hard at all. I saw her eat pasta only once!"

But the yoga devotee -- who flew her instructor, Mandy Ingber, from LA to her NYC set -- always eats enough to keep up her energy. "She routinely gets up at 5 in the morning to run before filming starts," says the insider, who was on set with Jen as she filmed The Bounty at Monmouth Park race track in Oceanport, N.J., on Aug. 17. "We were filming from 6 a.m. until almost 11 at night, and she had a great energy level the whole time. She was upbeat and smiley and never flubbed a line -- and her body looks amazing!"

The article adds that Jennifer "incorporates" a good diet and fitness into her lifestyle rather than "making them the enemy."

It sounds so easy, doesn't it? Too bad we can't all get her results!
