Chumlee has proudly showcased his incredible weight loss - leaving him difficult to recognize.

The reality TV star from hit show Pawn Stars shed an astonishing 160lbs after undergoing gastric sleeve surgery, TMZ reports.

Admitting that he was struggling with his weight and body image, Chumlee decided it was time for him to switch up his lifestyle for a healthier one.

Chumlee - real name Austin Lee Russell - said his weight constantly fluctuated 100lbs at a time, and admitted that the heaviest he's been was 350lbs in January 2019.

It was the following month he decided that enough is enough and went ahead with the surgery, per TMZ.

The popular weight-loss procedure sees a large portion of the stomach be removed to create a smaller stomach pouch.

This reduces the quantity of food one can eat while making them feel fuller even when consuming less food.

Chumlee was inspired to lose weight after his friend Corey Harrison did it first back in 2014 - going on a diet an intensive diet and exercise regime.

The TV star told of how he lost almost 100 pounds by "eliminating all processed foods".

"It was time for me to get healthy. I started at 320 [pounds] and now I'm down to 225," he said in 2014.

Chumlee added that "everything in moderation" became his motto before he turned to the surgery in order to keep his weight down.
