The last time Jared Lorenzen had a spot on an NFL roster, he weighed in at 285 lbs as a backup quarterback for the Indianapolis Colts. That was back in 2008.

Nearly a decade later, the former quarterback—who set records for the Kentucky Wildcats—has ballooned to 500 pounds.

That significant weight gain has inspired the now-36-year-old Lorenzen to get himself in healthier shape, which he will document with cameras in “The Jared Lorenzen Project.”

The project kicked into gear when Lorenzen linked up with filmmaker Anthony Holt, who previously chronicled the financial rise and fall of former Kentucky and NBA star Antoine Walker in the documentary Gone In an Instant, according to the Lexington Herald-Leader. In a preview of his project, Lorenzen said he hadn’t stepped on a scale since 2008 and the shock of seeing the number hit 500 pounds inspired him to lose weight.

Lorenzen released a video preview on Facebook:

Lorenzen, who won a Super Bowl ring as a backup to Eli Manning in 2008, last played organized football in the Continental Indoor Football League for the Northern Kentucky River Monsters, weighing in at 320 pounds in 2014.

Holt later connected Lorenzen with trainer Gunnar Peterson (who works with the Lakers and has worked with pro athletes and celebrities), and nutritionist Philip Goglia (who has previously worked with actors like Chris Pratt, Chris Hemsworth, Channing Tatum, Jai Courtney, Emilia Clarke, and Ryan Gosling).

“I’m lucky to have the team surrounding me right now,” Lorenzen said in the Facebook video. “It’s going to be a long journey, but on the other side, there’s a whole new, call it 'life,' on the other side.”

Here’s how Lorenzen looked throughout his football career.
