Despite being known for her toned figure, Aniston also revealed she doesn't like wearing skinny jeans.
"I don't try and follow trends because it just always feels inauthentic somehow. You know, like a skinny jean and me don't really get along.
"My husband loves me in skinny jeans, that's like all he wants me to wear. And he loves it. I personally love a nice flared option, kind of a '70s vibe or a ripped-up jean or something that's kind of loose."
The 46-year-old actress allows herself to cheat on her healthy diet once a week.
She told Yahoo Beauty Editor-in-Chief Bobbi Brown savory foods are her weakness.
"Whether it's a pasta or a burger or Mexican food, whatever my guilty pleasure is in terms of a greasy meal or some sort of saucy, salty or savory.
"I'm not much of a sweets person, so my treat would never really be sweets. And for my workouts, I've been doing this crazy spin class and then a yoga class."
