Kelly Clarkson has been incredibly open about her changing appearance ever since she entered the spotlight in 2002.

During her time on American Idol, the singer faced undue criticism with regard to her weight. "I was the biggest girl in the [American Idol cast] too. And I wasn't big, but people would call me big … I've kind of always gotten that," Kelly revealed on The Ellen DeGeneres Show in 2015.

How did Kelly Clarkson lose weight?

The 'Stronger' hitmaker credits Steven Gundry's Plant Paradox book as the secret to her incredible transformation. Speaking on NBC's Today show, she explained: "I had an autoimmune disease and a thyroid problem that started in like 2006.

"I read this book... it might not work for you but it worked wonderfully. Here's the best part, ya'll, it's not even the weight - I mean, I know the industry loves the weight gone, but I mean, for me, it wasn't really the weight. For me it was like, I'm not on my medicine anymore. My bloodwork came back and I haven't been on my medicine since like February."

Kelly Clarkson's daily diet

The mother-of-two doesn't restrict her diet. Whilst the star has introduced new items such as tapioca and almond flour, she still enjoys some of her favorite foods such as fried chicken and cake.

Since making the shift, Kelly has been incredibly candid about the added expense of eating healthy. Speaking on the Today Show, she explained: "And honestly, I'm gonna be real with you, it's really expensive to do. I wish the government would really back humanity on this, 'cause it's really hard to find. 

"I was poor growing up and there's no way my family could have afforded this. It helped out so much with health. My autoimmune disease is like, gone and I'm like 37 pounds lighter in my pleather."

Kelly added: "It's like understanding food and understanding what we do to our food, like spraying and pesticides and genetically-modified and like hormones we pump in and it's also about how pharmaceuticals have kind of like ruined our body, our flora, like everything and so, I don't really take medicine unless I absolutely need it."

Does Kelly Clarkson work out?

Whilst Kelly hasn't publicly spoken about her current fitness regime, the singer has previously opened up about how she used to visit the gym "all the time."

"It was a very dark time for me," she revealed. "I thought the only way out was quitting. I like wrecked my knees and my feet because all I would do is put [on] headphones and run. I was at the gym all the time."

Whatever it is that Kelly's doing, she's clearly managed to find an exercise routine that works for her.
