'Extreme Makeover: Weight Loss Edition' Chronicles Jarvez Hall Shedding Nearly Half His Body Weight (VIDEO)

In quite possibly the most impressive transformation yet, Jarvez Hall took the reigns of his own future on "Extreme Makeover: Weight Loss Edition" (Sun., 9 p.m. ET on ABC). The 28-year old husband said he agreed to take on this journey of change for his wife.

"I don’t want my wife to watch me die. I want her to look at me as her hero," Hall said. "And I can’t be that hero if I’m letting this weight stop me."

He didn't let his weight even slow him down. Hall started his weight loss adventure clocking in at 548 pounds, and after a year of working out with trainer Chris Powell, he dropped nearly half his body weight. That's enough to win almost any season of "The Biggest Loser."

In the end, Hall weighed in at a practically svelte 281 pounds, down 32 inches on his waistline. Even more exciting for him, he and his wife are now expecting their first child: a daughter.
