He was promoted to black belt in Brazilian jiu-jitsu by Cesar Gracie on May 8, 2007.
Prior to his debut professional mixed martial arts fight, Diaz's girlfriend, Stephanie died by suicide by walking in front of traffic. After her death, Diaz would run to his girlfriend's grave every day to tell her he would become the fighter she always wanted him to be.
