Jennifer Aniston Is 'Really Comfortable' at 110 to 113 Pounds

"If I was being super picky, I would love to drop five pounds," she said.

— -- Jennifer Aniston has always been svelte. However, even she would like to change a few things about her body.

"These days, if I was being super picky, I would love to drop five pounds," she told Yahoo. "That is just where I have always been really comfortable at about 110 to 113 pounds. But it is harder at this age."

Aniston, 45, explained that to stay in such great shape, she tries to "strike a balance," with her diet. (For example, weekends, she said, are the time when she lets herself have bread.) The actress also chalks up her looks to genetics, among other things.

Jennifer Aniston: I Wash My Hair Every Three Days

"My dad is 100 percent Greek; he turned 81 and he barely has a wrinkle. And neither does my grandmother, who was 95 when she died," she said. "But it’s also just water, drinking a lot of water, using really nice good products for your face. Don’t overproduct, that’s the other thing. Getting proper sleep is always important."

Still, when a wrinkle does crop up, don't expect Aniston to run to a plastic surgeon. The actress said that her fiancé Justin Theroux would "put a gun to my head if I touch my face in any way."
