rob kardashian weight loss sock line launch Rob Kardashian's weight loss on display at sock line releaseRob Kardashian recently unveiled his Arthur George sock line at Neiman Marcus — but he unveiled a svelter figure as well.

The youngest child of Kris Jenner and the late Robert Kardashian was showing off a trimmer waist line at the sock launch party in Las Vegas. He recently revealed that he put on a lot of weight in the last year after his break-up with Rita Ora and he’s been really down on himself.

However, now Rob is looking like the weight has started dropping, though he says he still has a ways to go.

“I still have to lose like 40 to 50 pounds, believe it or not,” Rob tells US Weekly. “Six months, I should be there.”

He also reveals he’s been working with the trainer his brother-in-law Lamar Odom uses.

“I’m kind of doing my own thing with Lamar [Odom’s] trainer. He’s on salary since he was 19 years old, so he works for us. I’ve been spending time with him,” says Rob. He’s also been cutting down on the drinking, which is a lot of empty calories.

“I’m trying to get in a healthy direction,” Rob finishes.
