Inside Kelly’s Weight Loss

Kelly Clarkson has always been comfortable in her own skin whatever dress size she wears. But in recent months the music star, 36 has looked decidedly trimmer than she has been since winning the American Idol way back in 2002. Fans noticed Clarkson’s new look as she wrapped up her first season as a judge on The Voice and stepped out at the Billboard Awards, but it wasn’t until June 6 that she explained her transformation.

“I did it for this autoimmune disease that I had and a thyroid issue,” Clarkson said of her weight loss in a red carpet interview with Extra. The singer began a new eating plan that advises cutting certain types of whole grains, dairy products, nuts and vegetables such as tomatoes after being diagnosed with a problem relating to her thyroid (an endocrine gland that stores and produces hormones and can affect energy and weight). “She had already lost a ton of weight by the time I saw her in March. Weight loss wasn’t the goal. This was an overall health approach.”
