Kanye West Is Behind Rob Kardashian's Weight Loss—Find Out How The Rapper Has Been Motivating Him!

Watch: Kanye West Is Behind Rob Kardashian's Weight Loss

Kanye West may have released his hit song “The New Workout Plan” back in 2004, but it sounds like Rob Kardashian has finally decided to jump onboard! It turns out the rapper has been a huge motivator for the reality star, and now he is starting to shed the pounds after gaining nearly 100 pounds in the past year and leaving the spotlight.

“It’s Kanye working his magic,” a source tells Us. “He’s been a great motivator for Rob. He told Rob how he got into shape after his accident and at a time when he was down in his life."

Back in 2002, Kanye got into a serious car accident that resulted in a broken jaw and left him in the hospital for weeks.

Coincidentally, Rob secluded himself after infamously leaving Paris last year right before Kim Kardashian and Kanye walked down the aisle, but it sounds like Kanye isn’t too peeved about that.

And so far, Rob is headed down the right track, as he is reportedly 15 pounds slimmer! “He’s always in and out. He makes it work with his schedule and he’s on his path,” his trainer Gunnar Peterson told Us.

In addition to Kanye being a big motivator for the 28-year-old, it sounds like returning to the small screen is also pushing Rob to lose the weight for good.
