All fruit diet lands Ashton Kutcher in the hospital

Ashton Kutcher might think twice before trying method acting again.

While preparing to play Steve Jobs in Joshua Michael Stern's biopic, "Jobs," the actor said he adopted the late Apple co-founder's fruit-only diet.

"First of all, the fruitarian diet can lead to like severe issues," Kutcher said after the "Jobs" screening at the Sundance Film Festival, via USA Today. "I went to the hospital like two days before we started shooting the movie. I was like doubled over in pain. My pancreas levels were completely out of whack."

In 2004, Jobs announced that he was being treated for pancreatic cancer.

In addition to eating like the tech titan, Kutcher said he watched 100 hours of footage to capture his walk and talk, according to Entertainment Weekly.

Josh Gad stars opposite Kutcher in the biopic, which is due out on April 19, as Apple co-founder Steve Wozniak.
