Is Kendal Jenner throwing hints at Rob Kardashian for him to start his weight loss?

Kendall Jenner posted on his Instagram a spliced clip of Rob Kardashian's old antics on "KUWTK."

In the clip, a visibly thinner Rob Kardashian can be seen laughing uncontrollably, at one point he was putting his face on his fist while giggling; then he is dancing goofily and playfully slapping his face. The model wrote, "This makes me ridiculously happy. @robkardashian."

A fan noted, "Been missing that goof on the show..."

"Rob Kardashian hasn't appeared on the reality show for a while, secluding himself after gaining weight and battling depression, sources have told PEOPLE. His mother Kris Jenner revealed in an April episode of KUWTK that he gained more than 100 lbs. this year," People said.

In an earlier report from the tabloids, Kris Jenner is reportedly going through extreme measures to help Rob Kardashian achieve some weight loss.

According to the July 27 edition of the National Enquirer, as shared by Celebrity Dirty Laundry, Rob Kardashian is set to undergo a gastric bypass surgery to achieve weight loss in record time.

The article alleged, "It's no secret that his monster momager Kris Jenner is embarrassed of her son's weight, and has been hounding him to stop binge eating and to get himself together for over a year now. According to a new report, Kris is actually forcing Rob to get gastric bypass surgery, and footing the bill."

The source added that Rob Kardashian really let himself go and achieving weight loss on his own volition would be very difficult.

"Rob has been living like a slob and gorging on food and drink to self-medicate," the source added. "His life has become unmanageable. He's reached a point where his health is at serious risk unless he does something drastic."
