Even "over the hill," Aniston is still looking fabulous. Recently, Gerard Butler, her co-star in "The Bounty Hunter," said that Aniston "has the best legs in Hollywood."
Aniston credits a mixture of the Zone Diet and regular exercise in the form of cardio and yoga for her figure.
In the GQ article, she said that by sticking to the Zone Diet, with occasional splurges, she keeps her body photo-spread ready.
The Zone Diet, created by Dr. Barry Sears, tells followers to eat a 40:30:30 ratio of carbs, proteins and fats.
Lawrence believes the zone diet is too high in proteins.
"You don't need more than 10 percent of your diet to be proteins," Lawrence said. "Bringing it up to 30 percent is unnecessary. There is also a big difference in plant-based proteins and animal-based proteins. The plant-based proteins like nuts and beans are superior to the animal-based proteins. It has been proven multiple times that cultures with high animal-based protein diets have an increased risk of heart disease."
