We Can’t Get Over These Before And After Photos Of Kelly Clarkson’s Weight Loss

How Kelly Clarkson Lost Weight Healthily, In Her Own Words

Clarkson's beauty has remained consistent throughout the years, however, her fans couldn't help but take note of her notably slender physique in 2018. The "Since U Been Gone" hitmaker attributed her weight loss of 37 pounds in 2018 to the "lectin-free" diet outlined in Dr. Steven Gundry's book, The Plant Paradox, following her two pregnancies.

"I did it for this autoimmune disease that I had and I had a thyroid issue, and now all my levels are back up. I’m not on medicine anymore because of this book," she told Extra at the time. She also sat down with Redbook and noted that while she is looking and feeling great now, her size never affected her success and self-love.

"It’s when I’m fat that I’m happy. People think, 'Oh, there’s something wrong with her. She’s putting on weight.' I’m like, 'Oh, no! I’m sorry, but that represents happiness in my emotional world,'" she said.

Clarkson continued: "If you gauge your life on what other people think, you’re going to be in a constant state of panic trying to please everyone. People should just concentrate on their own lives and their own health and their own happiness, and whatever that looks like for you, be happy with it."

During an interview with Glamour UK in 2020, Clarkson shared her strategy for managing criticism about her weight as her career flourished. She emphasized that developing a positive and healthy mindset was her top priority before addressing her physical health and weight loss.

"I felt more pressure from people actually when I was thin, when I was really thin and not super healthy because I just was worn out, just working so hard and not keeping healthy habits. But I felt more pressure," she noted.

The "Breakaway" singer added: "It was more of magazines shoved in front of you and, 'This is what you're competing with and we've got to compete with it.' I can't compete with that. That's not even my image. That's not who I am. That's who they are."

She went on: "I fought more when I was thinner than I do now, because now I just walk in and I just look at them like, 'I dare you to say something. I'm happy in my life. I'll work on me in my time!'"

In 2023, Clarkson is certainly crushing it, from epic style moments to releasing a rock-tinged, moving record Chemistry (written about her tumultuous divorce from Brandon Blackstock) to playing sold-out residency shows to wowing fans with her "Kellyoke" cover segments on her eponymous talk show!
