Rocker Rick had auditioned for the show (as seen on Saturday), where he revealed to the judges that by the age of 22 he peaked at 26 stone.
Rick, who will be coached by Paloma Faith on the show, hid away at home for more than four years because of his weight, but it was also during this time that he found his love for music.
His audition over the weekend was a hit with the judges, and his new rockstar look also made him a hit on social media.
Speaking on ITV's Good Morning Britain, Rick said: "I didn't expect that. I'm not complaining, like. The feedback from men and women has been incredible."
However, despite the weight loss, Rick said that he wants the focus to be on his voice.
"I didn't ever want the whole focus to be on [that]," he continued. "I mean, I'm proud about losing the weight but I wanted the focus to be on being a singer.
"I'm happy to inspire people, hopefully. I was always looking for ways to lose weight. I think the best way to do it is to send out a good example."
