Rob Kardashian's weight gain battle appears to have been a lost cause as the former "KUWTK" star was snapped on a burger run in Woodland Hills on Wednesday night.

The sock mogul is still shying away from the limelight as he took advantage of the dark to go out and avoid the paparazzi.

"Rob sported basketball shorts, high tops, and a baggy shirt for his outing at burger chain In 'N' Out, and then headed to a friend's house in Encino," Daily Mail said. "The former reality star's mother recently admitted she fears 'he is going to die' if she doesn't intervene with professional help."

According to various reports, Rob Kardashian's weight gain has already reached over 100 pounds.

This new photo effectively debunked previous rumors that he will join the "Dancing With the Stars."

Celebrity Dirty Laundry pointed to rumors that have been going the rounds that Rob Kardashian was approached by ABC to join "Dancing with the Stars" 2015 again and he's seriously considering it despite his weight gain.

"He desperately wants to lose the weight that he has gained, and he thinks that another round on Dancing With The Stars would do the trick," it said. "We're sure the fact that he is virtually broke and was cut out of his family's multi-million dollar reality TV deal could have something to do with it as well."

In an episode of "KUWTK," Kris Jenner sat down with Khloe Kadashian and Kim Kardashian with a specialist to find a way to address Robert Kardashian's weight gain.

"If I don't help him do something drastic, he's going to die," the "KUWTK" matriarch said. "I'm just waiting for this horrible thing to happen and there's nothing we can do about it."

Since Robert Kardashian's weight gain, he has been living in Khloe Kardashian's mansion.
