Michelle Aguilar is at Peace

Michelle Aguilar feels peaceful.

The winner of this season's The Biggest Loser told Us Weekly that she's calmer than ever.

"It's funny, but I feel at peace," she said. "I mean, I'm excited on the outside, but I also feel a real calm, like I'm fulfilling something that I was meant to fulfill -- and that feels great! I feel like this world is now my oyster, and I'm just going to go after it!"

Aguilar added that she isn't worried about packing on the pounds again now that she's off the show.

"I've got the greatest support team back home in my family. They serve as a constant reminder to me every day... I'm so lucky to have such a great family. I truly cherish them."
