It started as what is probably the most embarrassing moment of their lives, but something good came out of it. When a flight attendant approached Jan Coupe and her husband, she thought that the stewardess was going to check on their seatbelt. Instead, she told them that they were too heavy for the plane to take off!
That spurred the couple to go on a diet - between them, they have since lost 172 lb (78 kg):
Following the plane ordeal, and also to help with her MS, Mrs Coupe joined a Slimming World club. She persuaded her husband to attend and in the first week Mrs Coupe lost 8lb and Mr Coupe lost 9lb.
Instead of takeaways at night, the couple had pasta, vegetable curries or steak salads.
Now Mrs Coupe has lost 6st 5lb and her 54-year-old husband 5st 13lb. Mrs Coupe, who has also dropped six dress sizes to a 14, said: 'I don't feel embarrassed about getting on a plane anymore - we all feel so great we could fly around the world now without a hitch.'
