Since we were first introduced to him on Keeping Up With The Kardashians years ago, there is no hiding that Rob Kardashian has been gaining quite a bit of weight.

His struggles with his weight gain are also no big secret, either. However after months and months of being MIA, Rob is finally starting to come out from hiding and he’s even beginning to poke fun at his larger physical appearance!

For #ThrowbackThursday, he posted up a photo chugging down a milkshake with a caption that reads, “Started right here with these milkshakes hahaha… #throwbackthursday.”

So I’m guessing THAT’S what happened – makes sense! Milkshake looks super good though *hops in car and runs to McDonalds*

Check out his before and after photos in the gallery.
