Following his very public split from Blac Chyna, Rob Kardashian is in hiding — and has gained more weight, according to sources. The reality star is back to his old ways when it comes to his diet, and insiders told Life & Style earlier this year that the father-of-one is “eating his feelings.”

“He’s sitting at home, watching TV and spending thousands of dollars a month on Postmates [food delivery] and bingeing on Burger King, McDonald’s, Subway, and Taco Bell,” a source said. “He’s lonely, but he doesn’t want to face the outside world at all.”

Rob Kardashian’s weight loss was going well for a while.

During his relationship with Chyna, 29, the KUWTK star proudly flaunted his weight loss on social media, dropping from 298 pounds to 248 last year. However, the source revealed that he “ballooned back up to 300 pounds.” To make matters worse, Rob, 30, suffers from Type 2 Diabetes and has been hospitalized in the past for health issues related to the condition.

Last year, the sock designer opened up about his struggle to lose weight, and how he reacted to his diabetes diagnosis. “It was a big-time scare,” he told People. “I had found out I had type 2 diabetes six months before, but I stopped taking my insulin. I didn’t enjoy the routine. So I ended up non-stop throwing up and I couldn’t even swallow because my mouth was so dry. I felt like I was going to die.”

In an exclusive interview with Life & Style, celebrity personal trainer Gunnar Peterson also revealed that Rob was struggling to balance the gym and raising his daughter Dream. “[Rob’s a] devoted dad guy now,” he said. “He’s in that chapter, so it’s harder to get out. Anybody with kids, who’s doing the hands-on parenting approach understands that — it’s the hardest thing.”

Meanwhile, his family is concerned for him, especially sister Khloé Kardashian, who has been encouraging her little brother to be more active. “Everyone worries,” adds the insider, “that unless Rob changes his lifestyle, his health could take a serious turn for the worse.”
