Although her brother Rob is still trying to get over his weight problems, Kim Kardashian is done with feeling sorry for him.




During the most recent episode of "Keeping Up With the Kardashians," the 27-year-old Rob was MIA for the Kardashian family trip to Thailand.




While Khloé showed compassion, Kim didn't have much to give.




"We've all been here to offer him help and he won't take it, so I don't have sympathy," said Kanye West's wife during breakfast one day on the vacation.




When conducting her solo interview on the reality show, Kim said, "I think I'm just more of the tough love kind of person. My personality is like, 'All right, you complain, you don't like it, get up and do something about it.'"




However, Khloé is sure that her brother's issues are way deeper than his weight problem.




Rob, who also failed to show up at the Kimye wedding, is currently working out with infamous trainer Gunnar Peterson. The fitness guru claims the Kardashian is making great strides.




"Rob works out in beast mode," Peterson told PEOPLE last month. "I know he can do this."
