He has receded quite a bit from the public eye lately.
And Rob Kardashian has been concentrated on self-improvement during his period of relative privacy, a source told Entertainment Tonight.

The younger brother of Kim Kardashian has apparently leaned on professional assistance to trim his weight down.
Rob, who underwent an explosive breakup with Dream's mother Blac Chyna last year, 'needed to completely change his life, things were spiraling out of control for him and his health and relationships were suffering. He needed to refocus.'
The insider said of Rob, who is off of Instagram: 'Getting out of the spotlight was so important for Rob,' and also noted: 'His life is completely different now.'
The star has focused his attention on getting his life back on track for himself and for his daughter's sake.

This includes his younger half-sisters Kylie and Kendall Jenner, as well as his elder sisters Kourtney, Kim and Khloe Kardashian.
Kourtney, Kim, Khloe and Kylie all have children now – Khloe and Kylie having become mothers just this year – and their tykes have had quality time with Dream.
When Kim and Kanye West married in Florence in 2014, Rob was absent from the festivities, and his concern about his weight played a part, he recalled to People.

'I was doing my suit fittings in Paris right before the wedding and I just wasn't comfortable. I'm 6'1″ and at my most I probably weighed 300 lbs.'
Rob has famously had a close relationship with his elder sister Khloe, who has also had struggles with her weight over the years.
Last year, in fact, she began starring in a reality series called Revenge Body With Khloe Kardashian in which she helped guests achieve the figures they wanted.
