Rob Kardashian Blames Milkshakes for Weight Gain: See the Pic

Where's Rob?
Why Rob Kardashian didn't attend the ESPYs.

Oh, so that’s why Rob Kardashian gained so much weight. 

The reality star has recently become on a mission to lose weight, so it’s only normal that he’d open up to his millions of followers about what caused the dramatic weight gain. He’s blaming it on drinking too many milkshakes.

The 28-year-old posted a #throwbackThursday picture of himself drinking a milkshake on Instagram. “Started right here with these milkshakes hahaha👅👅 👿👿… #throwbackthursday,” he caption the pic, poking fun at himself.

During a recent episode of Keeping Up With the Kardashians, Kris Jenner revealed that Kardashian had gained 100 pounds in over a year. “I cry myself to sleep literally every night worrying about [Rob]. It’s breaking my heart.”

But he has been open on social media about his effort to get back in shape. Earlier this week, he wrote, “Spotted these fools on the morning workout,” next to a picture of his sister Kylie Jenner and boyfriend Tyga.

Even Kim Kardashian has tweeted about a couple of workout sessions with Rob.

You go, Rob! Just stay away from In-N-Out burgers too.
