"Biggest Loser" crowned John Rhode its Season 12 champion during Tuesday night's live finale. The 40-year-old special education teacher and football coach from Mesa, Arizona began the competition at 445 pounds and weighed-in at 225 pounds during the finale, giving him a 220-pound weight-loss. With the highest percentage of weight-loss on-campus this season, John bested former NFL player Antone Davis and tattoo artist Ramon Medeiros on the scales and claimed the $250,000 grand prize. "I made the most of every moment on the ranch because I knew (my wife) was at home struggling like a single parent, and with our two boys -- and our youngest is autistic," John revealed.NBC/Trae Patton - Wednesday, December, 14, 2011, 7:14 AM
