The 'Keeping Up With The Kardashians' star took to Instagram to reveal to fans that he has been working hard on his body over the past months and is looking forward to sharing his progress.

Posting an old picture of himself on Instagram, he captioned it: "I don't look like this anymore #thetransformationiscoming #staytuned #nosurgery #putinwork (sic)"

Back in October, a source claimed Rob is finding it "very difficult" to get motivated to lose weight despite trying to ditch the pounds for the sake of his daughter Dream.

The insider shared: "It's like Rob is finally realising the seriousness of being overweight and not taking care of himself. His family has been pushing very hard for him to work on himself. They keep telling him that he has no choice because Dream needs a healthier dad.

"It's very difficult for Rob to get motivated, especially when it comes to his diet. He is very much addicted to junk food. He is now working with a nutritionist to make healthier choices. Rob needs someone to be held accountable to. Someone that he sees on a regular basis and that won't accept bad food decisions. His family is hoping he will finally change."

Rob found himself hospitalised for a few days in December 2016, where he was

treated for complications related to his Type 2 Diabetes.

A source said at the time: "Rob wasn't feeling well and recognised that his symptoms were diabetes-related. Rob has made some changes to his lifestyle, but all the latest drama with Blac Chyna has made him depressed. And he has been on a terrible diet. He hasn't been taking care of himself, and that's why he's now sick again."
