Kelly Clarkson Reveals How She Lost Weight

Kelly Clarkson has revealed the secret behind her recent weight loss.

“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 told Extra on Wednesday. “I’m not on medicine anymore because of this book.”

Clarkson is referring to The Plant Paradox by Steven R. Gundry, MD. 

“It’s basically about how we cook our food, non-GMO, no pesticides, eating really organic,” the 36-year-old singer and mom to four kids, explained. “Literally, I haven’t worked out at all!”

Clarkson said people who notice her new figure assume she’s been hitting the gym. “People think I’m working out and I’m like, ‘Don’t think I’m going to come play some sport!’”

Clarkson recently took to Twitter to thank Carrie Underwood for sending her clothing from her CALIA activewear collection.

“Thank you as well because I’ve lost weight since you sent this. So it’s all too big for me which made me feel really thin,” she said. “But I’m gonna find someone that loves it.”
