We’ve all been there, Rob.

On Tuesday night, Rob Kardashian vowed (in front of all of social media) that he will finally lose the weight he’s been struggling with for the past few years.

The reality star took to Instagram and shared a couple throwback snaps of himself and fiancΓ©e Blac Chyna in their prime.

Kardashian essentially went into hiding about four years ago and struggledΒ with the weight and depression. Since meeting Chyna, he has somewhat come out of his shell, and has even returned to reality TV in his own spin-off, “Rob and Chyna.”

At one point, it was rumored that Kardashian had gained 150 pounds. He was hospitalized in December and diagnosed with diabetic ketoacidosis.

Might want to put this motivation on the fridge, Rob. That always worked for us.
