"I want to eat a burger," the Disney actress, 22, told PEOPLE backstage. "I am eating excessive amounts of food. I eat a doughnut a day, easily."
Kane, who explained that her rehearsal space is right next to a doughnut shop, added with a laugh, "Whenever we take a break, we usually wander over and get a Red Bull and a doughnut. This is, of course, the perfect combination for what any dancer needs."
All kidding aside, Kane, who is partnered with pro dancer Mark Ballas, admitted, "I've been using this show as an excuse to eat whatever I want and not feel bad about it."
But judging from the way she sounds – and looks – Kane's current eating habits aren't hurting her.
"I haven't lost or gained weight necessarily, but stuff is definitely shifting around," Kane said. "There are muscles where there weren't any [before], and it's been fun to kind of see the transformation."
