The 43-year-old actor, who plays Big Bob O'Hara in the BBC Scotland soap, revealed that he has conquered alcohol and cigarette addictions in the past, and now plans to address his weight.
"Those things got out of control and now this [weight] issue has as well. So I'm treating this the same way. People have been on at me about my weight since I was a wee boy," he told the Daily Record.
Urie, who is getting help from a therapist, dietician and physiotherapist to lose weight, will also tackle the issue in an upcoming River City storyline when Bob has a heart attack.
He added: "In the west of Scotland it's a huge issue, yet it is only really ever written about from a comedy viewpoint. We wanted to do it with a sympathetic west of Scotland character, an everyday guy whose mother feeds him steak pies. And I felt I could do that because that guy's me.
"What I'm trying to do now, as an older and wiser guy, is figure out why I behave the way I do with food. A lot of it is psychological, comparable with alcoholic behaviour.
"I don't want to be thin. I just want to lose a few more stone and be comfortable. That's a realistic aim for me. It's coming off really slowly, but that's the best way according to the people I'm working with."
