Rob Kardashian Weight: How Much Did He Lose and Who Keeps Him Motivated?

Since finding love with now fiancee Blac Chyna, Rob Kardashian is looking noticeably slimmer and he is now down to 248 pounds in short order. The Arthur George socks owner took to Instagram to flaunt his weight loss so far, but also revealed that he’s pushing to drop another 50 pounds.

“Looking from where I started 298lbs to my current weight now 248.4lbs,” Kardashian, 29, captioned a photo of a heavier version of himself standing next to a bikini-clad Chyna, 27, on the beach. “I'm focused and determined to reach my goal weight 200-205lbs.”

The former Keeping Up With The Kardashians star then gave a shout-out to his lady love, writing, “Happy I found my motivation,” accompanied by Chyna’s signature emoji, the smiling devil face.

Despite rumors that his family is unhappy about his recent engagement to Chyna, the 29-year-old seems to be doing well as he continues his quest to lose weight and get back to a healthier lifestyle.

A HollywoodLife source previously claimed that “Rob’s favorite machine to lose weight has been the elliptical. ... He has been on it every day trying to get in his low-impact cardio. He hates running on the treadmill.”

It's no secret that his famous family doesn't approve of his romance with Tyga's baby mama, but it seems like the Arthur George socks owner's relationship with Chyna have done more good than harm to him health wise.

"He has been eating much healthier with Blac, lots of chicken breast, fish and veggies," the source continued. "Besides the cardio, he has been doing some weight lifting, and Blac has even turned him on to yoga.”
