As we reported back in May, Fiddy posted a shocking picture of his extreme weight loss on Twitter showing a gaunt looking Mr.Cent as the star prepared for his role as a US footballer who is hit with cancer in new movie, Things That Fall Apart.
Now, the Baby By Me rapper has revealed that he looked at previous interviews with legendary actor De Niro, Bale and Hanks to see how they attempted to shed weight for similar roles.
Fiddy told US TV show The View: "I read [Robert] De Niro's interviews during Raging Bull, Christian Bale's during The Machinist, and Tom Hanks with Philadelphia."
The Candy Shop hit maker also revealed the very first meal he ate when filming for the flick had ended, telling the show: "I remember specifically what the first thing was, because I was starving,"
He continued: "I had a steak. It was 12 ounces, but I got about four ounces in before I started getting sleepy."
Earlier this year, the rapper claimed to a Cleveland newspaper that he went to huge lengths to achieve his extreme weight loss because the project was close to his heart.
The star, real name Curtis Jackson explained: "It's a project that I wrote, produced and financed myself. It's about a Heisman hopeful who could possibly be going to the league and everyone is assuming he's gonna make it, and then he's hit with an illness."
"I had a friend of mine who actually experienced cancer, and it's what motivated me to write this screenplay. You don't have to make everything personal, but that project was."
He added: "That's why I committed to playing a role where I lost 54 pounds. I had to discipline myself enough until I achieved it but ... I got it."
