Rob Kardashian's weight loss is now more evident as shown by recent photos of the former "KUWTK" star.

Recently, Rob Kardashian posted on Instagram a photo of him with a half-eaten plate of Zucchini as he dined with friends. In the photo, the sock mogul hid his face from the camera but he did show his leaner arm. He wrote, "Way off."

One fan wrote, "Hey @robkardashian looking great sweetie but your fans love no matter what your size is!"

Another fan ranted, "What kind of sick world do we live in that being big is a bad thing!? HOLLYWOOD is all messed up!! @robkardashian if you are losing weight for you to make you self (sic) happy then I am happy for you.. but if you choose to stay big and your happy with that, then am (sic) happy for you as well!!"

A third added, "I'm very happy for you. I don't think the media should be making such a big deal about your weight either way. I would like to say it's awesome seeing you post and getting back to your happy self!!!"

Radar Online also noted Rob Kardashian's weight loss progress by publishing some snaps of the sock mogul.
