Gary Barlow reveals he did not leave his house for about six months after his weight rose to 109 kg

Singer Gary Barlow has revealed he did not leave his house for about six months after his weight rose to 109 kg.

During his appearance on the "Lorraine" TV show, Barlow said he "was trying to kill off the pop star" in him amidst his weight issues and rivalry with former bandmate Robbie Williams, reported dailymail.co.uk.

He said: "Nine years (I stopped singing). Just turned my back on it. I was trying to kill off the pop star, that's what I was doing.

"I was eating away what a pop star looked like. I was just killing him off. Stopped dying the hair, stopped buying nice clothes, just wanted to look the opposite, physically and mentally."

Years later, the "Back for good" hitmaker managed to shed the weight, after meeting diet gurus Melissa and Jasmine Hemsley.

"It was the day when I just went, 'No, I'm not having this anymore, I'm going to change. I want to change and I'm determined that this is not who I've become.'

"It only took a few years to get that low, but it took me years to get back to who I wanted to be. 10 years probably," he added.
