Rob Kardashian Has Lost ‘More Than 15 Pounds’ Training With Gunnar Peterson, Shares New Instagram Photo [Report]

Rob Kardashian has reportedly lost more than 15 pounds. According to an Us Weekly report on September 9, the Keeping Up with the Kardashians star and creator of the Arthur George sock line is determined to make a comeback and has already made some serious progress.

Rob Kardashian, who the magazine claimed gained 100 pounds in one year, has “already lost more than 15 pounds,” said the magazine’s source.

“[Rob Kardashian] has been sticking to the plan Gunnar [Peterson] created for him, and is getting meal delivery from a chef.”

Rob Kardashian has been struggling with his weight, as well as depression, for the last couple of years, and during an earlier season of Keeping Up with the Kardashians, he opened up about his struggles. Unfortunately, however, it took Rob Kardashian a while to truly get motivated to make a positive change.

The magazine alleged Rob Kardashian hadn’t stepped out publicly since he ditched Kim and Kanye West’s May 2014 wedding in Europe, but he has been spotted by the paparazzi in Los Angeles a couple of times at In ‘N Out Burger in the year-and-a-half since.

While Rob Kardashian has a ways to go before he’s back to his previous size, Us Weekly claims the reality star and designer has already began filming for season 11 of Keeping Up With The Kardashians, which is expected to premiere sometime next year. The magazine also noted Rob Kardashian’s financial motivation behind filming.

“[Rob Kardashian]’s not getting paid if he doesn’t film. He has a $2 million-a-year contract. He realized he couldn’t give up this huge opportunity.”

Throughout filming, Kanye West has allegedly been “a great motivator” for Rob Kardashian to lose the alleged 100 pounds he gained after starring on the 13th season of Dancing with the Stars.

On September 5, Rob Kardashian shared a new photo with fans on Instagram, along with the caption, “Way off.” In the photo, Rob Kardashian was seen from the side, enjoying what looked to be a salad and some sort of tea. In just four days, the photo received over 105,000 likes and over 2,000 comments.

While Us Weekly claimed Rob Kardashian lost more than 15 pounds, a Radar Online report claims he’s actually lost 20 pounds.

“[Rob Kardashian] is constantly working out with Gunnar Peterson who helped Khloe and Kourtney shed all of their weight. He’s lost 20 pounds so far!” a source close to the family told Radar earlier this week.

“[Rob Kardashian] is working out almost every single day now and he is doing lots of cardio. He’s been hiking, jogging and walking.”
