Zoe Kravitz says she shed 20lbs for movie role by eating clay!

I've heard of all types of diet tricks but this is a new one! Say what now Zoe Kravitz?!?

The 25-year-old daughter of rocker Lenny Kravitz & 'Cosby' actress Lisa Bonet plays an anorexic and bulimic character in "The Road Within" and she recently opened up about how she shed 20 pounds to play Marie.

"I did a cleanse," she told Us Weekly at the premiere Wednesday during the Los Angeles Film Festival. "I tried to do it the healthiest way as possible, even though it's not healthy to do."

"I ended up drinking clay," she admitted. "Because it cleans out your body and fills you up. I was eating like a Mason jar of pureed vegetables a day and running."

OMG! Clay?!? Hayi no! 

Kravitz went on to dish to Us that while the diet worked, she said it was "awful" and would "never encourage anyone" to do it.

Dr. Roshini Raj, a gastroenterologist and TODAY contributor says "there probably isn’t any harm in eating clay, as long as you only do it occasionally. (Done in excess, it could cause constipation)

Hmmm would you do it? I don't know!
