Rob Kardashian seems to be gaining more weight instead of shedding pounds as his momager Kris Jenner has revealed just how much weight he has picked up within the last year on Keeping Up With the Kardashians.

The family tried to enjoy their trip to Thailand without Kardashian, but Jenner couldn't help but speak on her son's absence.

She told her stepson, Brandon Jenner in the episode that aired Sunday, "Rob wants to be a little bit private. Over the course of the year, he's gained 75 pounds. It's devastating. Robert isn't in a strong place right now."

Still, Kim Kardashian also seemed to back away from trying to help Rob after he shut her down so many times. In a sneak peek of the episode to air August 10, the family discusses Rob's decision not to come on the family trip, after missing other major moments like Christmas.

"We've all been there to help him and he won't take it. So I don't have sympathy."

But his number one supporter Khloe continued to say that he has been through too much lately for the family to leave him hanging.

Kim told the cameras, "Khloe wants to fix everything and fix the situation but she can't. I think I'm just a little bit more of the tough love kind of person. My personality is like, 'You complain you don't like it. Get up and do something about it.'"

But Khloe also revealed how her brother's issues has put her life on pause and stated that "tough love" is much easier to claim but not so simple to execute.

Keeping Up With the Kardashians airs Sundays on E! at 9/8c.
