may have recently won American Idol
, but she has also lost something, too – 30 lbs.!
"Over the course of the show, from January to May, I probably dropped 20 lbs.
And I've lost about 10 more since the finale," Glover, 23, told PEOPLE Tuesday while rehearsing for the American Idol Live! 2013 Tour.
"It is always good to be healthy, so I am happy about it."
But her weight loss hasn't come from time in the gym. It's a byproduct of Glover's busy lifestyle as she rehearses for the tour and prepares her debut album, set to be released Oct. 8.
"I've always – well maybe I haven't always
– been comfortable with who I am. This weight is just dropping off because of my crazy schedule," the season 12 winner said. "I just walk a lot in the airports, and then we are rehearsing the choreography. I call [the rehearsal room] the gym, to be honest."
While Glover has not been actively losing weight, one of her fellow Idols is working extra hard to make sure he's fit before the tour launches July 19.
"When I went back home [after being eliminated], I wanted to lose more weight so I had some wiggle room just in case I decided to go crazy with the food," said season 12 finalist
Burnell Taylor, who initially lost 40 lbs. in a month
after his first audition.
Taylor lost the weight without a trainer and only a treadmill.
"I look at old pictures of myself and try and stop myself from crying because it is just amazing," Taylor says of his weight-loss transformation. "After the tour, I want to get a six-pack because I have wanted that since I was fat. I want that to be how I am for the rest of my life."
