Camera-shy reality TV star Rob Kardashian has just offered some proof that he is on his way back to fitness. On Sunday, he posted a selfie, which shows a much slimmer face.

“Gnight,” he said, in the simple caption for the close-up photo. He posted the selfie in black-and-white and the rest of his body is not shown. However, the close-up on his face reveals a much slimmer look. This is the first time he has revealed a recent photo after he started speaking up about his weight.

Last week, he joked about gaining weight due to his consumption of milkshakes. He also marked his return to Instagram by posting a throwback photo of himself enjoying a pulled pork sandwich. He returned to Instagram a month ago after posting and deleting occasionally in the past two years.

Since his latest comeback, he has posted mostly just throwback photos of himself or photos of family members and memes. Sunday’s post reveals the results of what is said to be his newfound commitment to getting back in shape.

Rob’s sister Kim Kardashian has also been vocal about working out with her brother. In the past two weeks, she has spoken about going hiking and working out with him.

Rob has been struggling with his weight in recent years and Kim recently confirmed in an interview with Rolling Stone magazine that he has stopped appearing on “Keeping up With the Kardashians” due to his weight.

It remains to be seen if he will be able to get back in shape and choose to appear in the show when it resumes airing this fall. “Keeping Up With the Kardashians” is scheduled to return in November on E!.
