Rob Kardashian Weight Gain: 'KUWTK' Star Gained 75 Pounds In One Year

Kris Jenner discussed Rob Kardashian's shocking weight gain on a recent episode of Keeping Up With The Kardashians.

While explaining why her son didn't come along for the family's vacation in Taiwan, Jenner revealed Kardashian had gained a whopping 75 pounds in one year's time.

Speaking to her step-son Brandon, Jenner claimed Kardashian "wants to be a little bit private. Over the course of the year, he’s gained 75 pounds. It’s devastating.” Also during the episode, which was recapped by In Touch Weekly on Aug. 4, Jenner explained, "Robert isn't in a strong place right now."

In recent months, Kardashian, a sock designer, has done his best to keep his struggles private. In addition to cutting back from filming his family's reality show, Kardashian is rarely seen in public. In fact, he's only been photographed a handful of times in the last year -- one of which was during a trip to Europe for his sister's wedding to Kanye West.

Still, despite his removing himself from society, his family has stuck by him, namely his sister, Khloe, whom he lived with for a number of years.

On Sunday night's episode of Keeping Up With The Kardashians, Khloe was extremely concerned for her brother's mental state discussed catching a flight back to Los Angeles from Taiwan to be with him.

Unfortunately, Kim hasn't been so supportive.

"We've all been here to offer him help and he won't take it," she said during a recent episode. "So I don't have sympathy."

Keeping Up With The Kardashians airs on Sunday nights at 9 p.m. on E!
