As Adam has realized, stardom isn't a quick fix for all your problems. Since high school, Adam says he's struggled with self-esteem issues.
"I think as you get older, you learn to just kind of live with them. You're like, 'Oh, I'm kind of self-conscious about that,'" he says. "[In high school], I was much heavier. I was just awkward. I was in the closet, all sorts of things. I didn't feel attractive at all."
At his heaviest, Adam says he weighed 240 pounds. Today, he says he's down to 175, 15 to 20 pounds lighter than he was during Idol, thanks to a meal-delivery program that helps him control calories and portions.
