Slimmed-down Rob Kardashian poses in front of healthy meal in new Instagram snap as he continues his return to social media

He's taken himself out of the limelight to focus on his weight-loss.

And it seems that Rob Kardashian, 28, is finally feeling more confident about his image as he took to Instagram to share the first photo of his leaner look on Saturday.

Other than a recent selfie, the only photos that Rob has shared of himself have been 'throwback' pictures, displaying his former svelte self.

But in the snap, the Keeping up with the Kardashian star's arms are clearly visible, and they certainly look a lot more toned than before.

His tattoo sleeve is also seen in the picture, along with his slimmed-down face, which he partly conceals behind a baseball cap.

Rob is pictured next to a plate of unfinished healthy food as stares down at the table.

He simply captioned the snap 'way off', which could suggest he feels a long way off from his target weight, although a number of fans in the comments believe this refers to him feeling hungover.

Rob's struggles with his weight have been well-documented in the E! reality show, which he starred in alongside sisters Kim, Kourtney and Khloe, but stopped appearing in in 2013.

And family friend Malika Haqq recently revealed that the youngest Kardashian is doing well. 

The 32-year-old television personality, who stars in the Keeping Up With The Kardashians spin-off show, Dash Dolls, updated fans on the progress Rob has made in a recent interview with E! News as she said: 'Rob is doing very well.

'He has been working out and taking care of himself. I think Rob shares what he wants to share. I think that's how it should be for everyone.

'When you're ready you post, post. When you're ready to be seen, be seen. When you don't, leave him alone.'

Last week, Rob shared a black and white selfie showing a more slimmed-down face and a confident pose.

Momager Kris Jenner even recently confirmed that her only boy - the younger sibling of Kourtney, Kim and Khloe and older half-brother of Kendall and Kylie Jenner - has been making some positive changes in recent months.

Go Gothic in Kris' black gown by Givenchy

The MTV VMAs was just another girly night out for the Kardashian/Jenners.

Kim was of course there to support Kanye West, but she brought sisters Kourtney and Kylie along too. And when it comes to red carpet style, anything they can do, momager Kris can do even better!

Her daughters all looked beautiful in Balmain, but Kris opted for another family favorite. Her dress is by Givenchy, the label behind Kim's wedding gown, and we love the halterneck wrap strap. The long silk-trimmed sleeves add Gothic vibes, while the plunging neckline adds a racy element. And when teamed with a Bottega Veneta bag, Kris was definitely among the best dressed guests on the night.

But the best news is that you can actually buy this exact dress. And it's on sale! Click the link (right) to get it now at Farfetch, then save it for a big night out during party season.

Or kopy Kris with a little help from the edit below. Forever Unique's halterneck dress is too hot to handle!

The proud matriarch told ET: 'He's doing terrific. Robert's good. He's working out and eating [well], so he's on a good path right now.'

Rob, who missed their summer getaway to St. Barts, was last seen on Keeping Up With The Kardashians in 2013, struggling with his weight gain and self-confidence issues, as well as battling depression. 

Rob recently proved he had got his spark back, showing off his sense of humour with a throwback snap of himself sipping on a milkshake, with two empty glasses on the table in front of him.

Making light of his current fitness situation, Rob joked: 'Started right here with these milkshakes hahaha... #throwbackthursday.'  

It seems as if Rob is getting the family support he needs as even older sister Kim Kardashian has helped whip him back into shape as a workout buddy.

'Just went on the hardest hike every today with @robkardashian,' the expecting 34-year-old wife of Kanye West tweeted - which Rob posted a screenshot of on Instagram a few weeks ago.

And he proved he's been maintaining his morning workouts. Just a few days ago, he wrote, 'Spotted these fools on the morning workout,' with a picture of his sister Kylie Jenner and beau Tyga. 

Things certainly seem to be headed in the right direction as a source told E! News earlier this week that: 'for the first time in a long time Rob is committed to changing his diet habits.'

Rob has also been working with celebrity trainer, Gunnar Peterson, as the insider added: 'His regimen involves more than just cardio and weights.'

A rare sighting: Rob, seen here in May 2014, became a recluse over a year ago when his weight ballooned. He went from a fit cover boy to an out-of-shape man teetering on the edge of obesity after a painful split with British songbird Rita Ora in December 2012
