Khloé Kardashian says that her brother Rob Kardashian, who has long struggled with weight problems, is a whole new man since he was told he has diabetes.

The 31-year-old Kardashian sister says she thinks a phone call "intervention" she had with her brother that aired on Keeping Up With The Kardashians helped him start to turn things around.

"We didn't mean to film [it] — it just happened," she told E! News. "It was, like, over the phone. We just needed to really address a lot of stuff with Rob. And it came to be that I'm an enabler because I baby him too much, but I can't kick my brother out, that's never gonna happen."

Rob, 28, was hospitalized the week before New Year's, and that's when doctors informed him that he is diabetic. The health scare was a "wake-up call," sources have said.

"I've seen such a great transformation just mentally right now," said Khloé. "It's only been a week, but I hope that sticks and I'm always praying and rooting for Rob."
