A man who lost sixteen stone is to run his first half-marathon today to raise money for a hospital that he says helped change his life.

One-and-a-half years ago Ash Begg weighed 28 stone.

Ash, 30, who lives in Sparkhill in Birmingham, says a lot of his weight gain was from the stress of his brother being detained in Guantanamo Bay.

Moazamm Begg was wrongly suspected of being a terrorist and Ash says he looked to food for comfort.

In 2010 Ash underwent a gastric band operation at Heartlands hospital and says his life was transformed.

"I feel like I've been reborn. I'm a completely different person to what i was before."

To mark his achievement Ash decided to compete in the half-marathon and give the money raised to the weight management team at the hospital.

"It's nice to do it for the NHS because I feel they have helped me tremendously giving me this opeation and there's a lot of stigma attached to this operation."

Once he has completed the race Ash is looking forward to his next goal - to become a personal trainer so he can show others how to lead a happy healthier lifestyle.
