Following his win as Australia's sole Survivor, Jericho has shared pictures from before and after he was on the island, comparing his shocking weight loss!
This definitely isn't the first time that castaways have shared pictures of the dramatic amount of weight they lost from competing on the show - but Jericho almost looks like another person!
Taking to Instagram, the 25-year-old shared the photos side by side with his 17.4K followers.
"Before and after survivor #nofilter," he wrote.
"Fitness peeps Help me get back into shape! TAG A PT!! #55days #transformation #survivorisreal #sunblackskin #hairgrew #healthylifestyle to #fooddeprived #gym to #nogym."
We're sure it won't take too long for Jericho to get back to his old crazily buff self!
