Bree Boyce used to weigh 234 pounds and wore a size 18.
She lost a dramatic 112 pounds over the course of three years through healthy eating, regular exercise and with the help of a nutritionist.
At last month's Miss Carolina pageant, she wowed the audience during the talent portion, won the swimsuit round and went on to win the crown.
Now she wants to inspire others to live healthier lives.
"And it was through hard work and determination and perseverance. And I'm just so happy to say that i did this for no one else but for myself."
Bree will compete for the Miss America crown in January.
