Watch the week-by-week slideshow of Koli's transformation on The Biggest Loser Season 9. He may have drawn criticisms for what some believe to be arrogance, but no one can deny he's worked his butt off, to go from 403lbs to 188lbs. Let's congratulate Koli for winning the at-home prize of $100,000, and losing the greatest percentage of all contestants (53.35%) this season. Keep it up, Koli!
