James was an inspiration to his wife, Joyce Quinn ,who also followed the strict diet to reduce weight to six dress sizes.
Their teamwork is commendable and they were recently felicitated as the Slimming World's Couple of the Year.
James became obese and weighed a terrible 27-and- a-half stone. Though he was a fitness instructor in the past, James lost control of what he was eating and began to gorge on fried breakfasts, crisps and chocolate. His waist was a massive 62 inches.
The couple signed up to weight loss classes and has shed a remarkable 20 stones between them.
Mr Quinn, 45, said: "I had given up on life. I genuinely thought my family would be better off if I went to sleep one night and did not wake up.
"I was so tired I didn't do anything around the house. Joyce did everything for me and it was affecting our relationship."
Mrs Quinn, 47, said: "I was so worried about James that I did not give my own weight any thought. It was only when I saw a photo of myself that I realized I needed to lose weight too."
Mr Quinn experienced a remarkable weight loss. He lost 30ins from his waist, while his wife has dropped 4st 5lbs to 10st 13lbs.
Mr Quinn added: "I asked Joyce, 'How long do you think our marriage would have lasted if we had not lost weight?' She said, 'How long do you think you would have lived?' "We have a second chance - and we love every minute of it."
