Go Rob Kardashian! The reality star is looking sexy yet again—and we have Blac Chyna to thank!

Rob put on approximately 100 pounds after splitting from Rita Ora, but Blac Chyna has been working hard to get him back to his goal weight.

The 27-year-old frequently shares Snapchat videos of the meals she cooks for him—and of course they are all healthy!

And the results are evident! Blac Chyna must have the key to something we don't know about because Rob looks happier and more confident than ever!
