Rob Kardashian is continuing his weight loss efforts. The 26-year-old "Keeping Up With the Kardashians" star was recently photographed heading to a meeting in L.A. after hitting the gym on Jan. 27.

Kardashian covered up his body in a black sweatshirt and long black workout pants. The reality star looked noticeably heavier than he did back in May when he chatted to Us Weekly about the diet and exercise plan he started last February. "I still have to lose like 40 to 50 pounds believe it or not," he told Us at the time while promoting his Arthur George by Rob Kardashian sock line. "Six months I should be there."

In a February 2013 episode of "Kourtney & Kim Take Miami," Kardashian blamed his weight gain on his break up with singer Rita Ora. "It's crazy how this whole year, my whole relationship was only negative," he said. "All I did was gain f------ 40 pounds and lose so much money."

His struggle to keep the weight off is taking its toll. "Rob is really depressed," a source tells Us. "He's not as close with his family right now, and he won't answer a lot of texts and calls from friends."

"Rob has a trainer he's supposedly working out with," an insider adds. "But Rob rarely shows up for their sessions. He's not losing any weight. The family is very concerned about him."
