Kelly Clarkson's Magical Weight Loss Secret Revealed: Harry Potter and the Shape-Shifting Spanx!!

Kelly Clarkson is finally talking about her apparent weight loss, which she dodged discussing in recent months."I literally read this book, and I did it for this autoimmune disease that I had and I had a thyroid issue, and now all my levels are back up," she explained to "Extra." "I'm not on medicine anymore because of this book, it's called 'The Plant Paradox (by Steven R. Gundry, MD).' It's basically about how we cook our food, non-GMO, no pesticides, eating really organic …"

She didn't reveal the autoimmune disease or provide further details on the thyroid issue.Surprisingly, however, the "Meaning of Life" songstress hasn't lifted a dumbbell in her efforts to shed the pounds, despite people insisting she has.

"I'm not working out! I think people think I'm working out and I'm like, 'Don't think I'm going to come play some sport!'"

She added, "Literally, I haven't worked out at all!"

Clarkson had been playing coy with her weight loss recently, crediting her glam squad with transforming her."I have to shout out my whole glam squad," Clarkson joked of her svelte appearance at "The Voice" finale last month. "I literally hired Harry Potter and Spanx; it's all like a sausage."
