The youngest of the Kardashian siblings has been in seclusion since he skipped sister Kim's wedding to Kanye West in 2014. He also hasn't been seen on the family's reality show, Keeping Up with the Kardashians, since 2012.
Kardashian, 28, has reportedly been battling depression and gained more than 100 pounds in the span of a year. But he's now on a weight-loss plan that includes exercise and meals prepared by a chef and delivered to his home.
He will reportedly be seen in the upcoming season of Keeping Up with the Kardashians, which is currently in production. On Aug. 31, Kardashian posted a photo of himself on Instagram. Check it out here:
