Rob Kardashian’s Battle With Fat Sends ‘KUWTK’ Star To Treatment Center? Momager Kris Jenner’s Son Enters Rehab In Arizona

Rob Kardashian's battle with fat led the "Keeping Up with the Kardashians" star to a treatment center as momager Kris Jenner's son enrolled himself in a rehab program in Arizona.

Rob Kardashian's weight gain is supposedly weighing down on the sock mogul that he's now battling depression for several months now, according to Star magazine. Now, the only boy in the Kardashian brood has entered The Meadows trauma and addiction center in Phoenix.

The publication said that because of Rob Kardashian's battle with fat, he struggled with substance abuse not just with alcohol but also weed and prescription cough syrup as well.

It was earlier reported by Us Weekly that Khloe Kardashian reached out to and open up her home to Rob Kardashian.

"Living alone isolated him. Rob needs to be around people who love him," a source told Us Weekly.

Among all the sisters, Khloe Kardashian was the one who remains supportive of Rob Kardashian's battle with fat, while Kim Kardashian and Kourtney were very critical and momager Kris Jenner was very harsh even to the point of telling him that he has no say in family matters until he's earning his keep, according to Star.

"Rob has never been in such bad shape - emotionally or physically. Rob was drinking a lot of Sizzurp, and that's one of the reasons he gained so much weight," the source told Star, citing the high sugar content of the syrup.

Because of Rob Kardashian's weight gain, the "Keeping Up with the Kardashians" actor is "well past the point of desperation and now is just flatout miserable."

The Star earlier reported that Kris Jenner has been very harsh of her criticisms over Rob Kardashian's weight gain.

"She called him a fat slob and said he's losing out on business opportunities because no one wants someone as huge as him representing their products," the source told Star.
