If you can't handle the heat, get out of Rob Kardashian's kitchen!

In a sneak preview of Sunday's new Keeping Up with the Kardashians, Khloe Kardashian finally makes the decision to move in with family.

But with Kris Jenner's house a bit full (Kim Kardashian, Kanye West and North West are just a few lucky guests), Khloé decides her brother's new bachelor pad is the best place to stay.

Unfortunately, Rob is having a bit of trouble adjusting to a new houseguest.  "All I want to do is stay focused on my plan," he confesses. "I need to do things my way and Khloé is interfering with that."

Between lighting candles all over the house and placing cheese in the refrigerator, Khloé is testing Rob's patience.

"When I live alone, all I have in my fridge is water, my protein powders and that's it," Rob says.

"Why are you getting so mad over cheese," Khloé asks after graciously making chicken and Mac & Cheese for dinner.

"It's not about cheese," Rob argues. "It's about this being my s---!" Uhoh!

With a goal to lose 60 pounds as soon as possible, Rob is making it clear that health and fitness is his top priority.

"I've been the most unhappiest person for about a year and a half and it's very, very easy to just fall off the wagon," Rob says. "I need to literally dedicate my whole life to my fitness."
