Zoe Kravitz ate what to lose 20 pounds?!
The already slim Zoe Kravitz dropped a shocking 20 pounds to play an anorexic and bulimic character in her new film The Road Within, and opened up to Us Weekly recently about how she was able to drop the considerable amount of weight off of her petite frame.
"I ended up drinking clay," she surprisingly revealed, "because it cleans out your body and fills you up. I was eating like a Mason jar of pureed vegetables a day and running."

The 25-year-old X-Men: First Class actress also did a cleanse.
"I tried to do it the healthiest way as possible, even though it's not healthy to do," she admitted.
But Zoe of course, wouldn't recommend the extreme diet to anyone.
"I was a space cadet," she said of her mentality during the "awful" experience, also admitting that she's struggled with eating disorders in the past.
Though Zoe isn't the only slender star who's recently copped to eating clay -- her Divergent co-star Shailene Woodley famously raised a lot of eyebrows when she explained the benefits of eating clay on the Late Show with David Letterman in May.
"Clay binds to other materials in your body and helps your body excrete those materials – that are not necessarily the best for you," Woodley explained about her unusual food of choice.
