John Harding was asked to move seats on a flight to Australia to 'even up the weight' - and that's when he knew something had to be done about his sizeable frame.
John, of Cawthorne, weighed 17 stone but after just three months at a gym he has managed to drop four of them.
The 44-year-old joined Royston Leisure Centre in September after the embarrassment of being asked to move to the other side of a plane on a flight to Australia.
Just three months down the line from his first gym session and John hasn't looked back.
He now weighs 13 stone, has lost four inches off his waist and is enjoying life to the full.
"I've almost reached my ideal weight now, but I'm still going to continue visiting the gym at least three times a week. I really enjoy the atmosphere there and it's great to be feeling so much fitter and healthier.”
