Jackson Medical Mall founder Dr. Aaron Shirley came up with plan last year to help tackle Mississippi's obesity problem after watching 3 On Your Side's Commit to Be Fit series of reports.
He challenged churches to compete against each other in a weight loss battle.
Winners were announced during the 2012 Community Reinvestment Awards program at the Jackson Medical Mall.
There were five finalists, but it was True Light Missionary Baptist Church that took the top prize of $5,000 and bragging rights.
Lori Greer, deputy director and CFO of the Medical Mall Foundation, said she hopes bragging rights won't be the only benefit.
"Hopefully, it will continue on. they will teach their children the activities that they learned to keep the weight off and we hope it will go statewide," Greer said.
Second runner up was Greater Bethlehem Temple Apostolic Church. Anderson South United Methodist Church was third runner up.
In all, the churches have shed 3,500 pounds since the competition began in January.
