It is a common basis for a newspaper feature – ‘person loses X stone after ride embarrassment’ – or something similar.
But how did this specific type of situation come to be a crucial motivator for so many people to lose weight?
The answer has to be partly to do with how a day out at a theme park is supposed to be about escapism from the realities of life.
Being told that you cannot ride a rollercoaster or other attraction because of your size would be an extremely traumatic and embarrassing event for many people.
The situation is exacerbated because it has taken place in an environment of escapism and fun.
An issue that is frequently a source of unhappiness in daily life coming up on a day out to a theme park has been the inspiration numerous people have needed to finally take losing weight seriously.
“All I could feel was the sniggers. I tried to laugh it off but inside I was crying with shame,” Donna McCann said after being rejected from an M&Ds rollercoaster in Scotland.
She weighed around 18 stone at that point.
“I was embarrassed to the core. I cringed at the thought of being humiliated in front of a crowd of people again,” Donna, now 10 stone added.
Another reason that has been cited for people losing weight as a result of ride rejection is seeing their young children miss out on fun experiences.
Hayley Donaldson was approaching 20 stone when she was told that she was too big to ride the drop tower while accompanying her daughter at Gullivers Kingdom.
“I was too big for the safety bar to come down and so had to do the walk of shame off the ride,” she said.
“It made me realise my child had to miss out on something because of my size.”
In the United States, rides are increasingly being fitted with seats capable of accommodating those with larger girths, but these customisations have only been seen on a limited scale in the UK so far.
