He is reportedly 'really depressed' and is still attempting to lose weight amid reports his family are putting pressure on him to slim down.

And now, Rob Kardashian has deleted all but two photographs on his Instagram account.

It is not clear when the 26-year-old reality star erased the snaps, but the only pictures which remain are a grab he posted on Friday advising his fans to sign up to video service Keek and a snap of himself with sister Khloe Kardashian in their younger days.

The only son of Kris Jenner and the late Robert Kardashian Sr has struggled with his weight since his split from British singer Rita Ora back in

'Rob is really depressed,' a source told Us Weekly. 'He's not as close with his family right now, and he won't answer a lot of texts and calls from friends.

'Rob has a trainer he's supposedly working out with,' another insider said. 'But Rob rarely shows up for their sessions. He's not losing any weight. The family is very concerned about him.'

Last year, sources claimed that Rob relocated to Florida three months ago in a bid to escape the intense media spotlight that surrounds his family.

'He finally realised he needs to focus on himself and not do things the way his sisters do. He feels he needs a clean break,' an insider told In Touch in January.

'Rob feels like his family can't see anything beyond the spotlight. But he wants more for himself than fame.'

The reality TV star has had a tough time over the past two years. He gained more than 60lbs after his split from singer Rita Ora, and has since made headlines for his fluctuating weight. On top of that he's also been grappling with premature balding.

In addition, he is said to have struggled with the breakdown of sister Khloe's marriage with his close friend Lamar Odom as well as his mother's separation from Bruce - his stepdad of 22 years.
