An embarrassed mum lost eight stone in 12 months after the shame of getting jammed in a climbing tunnel at a children's soft play centre.
Size 24 Emma Kingston, 29, was playing with her 18-month-old son Freddie at Crazy Knights soft play centre in Oswestry, Shropshire.
She followed him through a tunnel from the ball pit but then became stuck fast. To her utter humiliation, she had to scream for two staff members to haul her out.
Emma, who weighed 18 stone at the time, said: "We got to the rollers which normal-sized adults can fit through. I started and knew there was no way I could get through them.
"I suddenly got stuck. I was with my cousin and she had to carry on with Freddie while two members of staff helped get me out.
"It was so embarrassing having to go back the way I had come against all the people coming through the play centre.
"It was then that I signed up to Slimming World because something had to be done."
Emma had piled on the pounds after getting hooked on Big Macs and pizzas, washed down with litres of cola. But has slimmed down to a trim 10 stone in just 12 months.
Emma added: "I had been a size 18 since after I had left school and got a job, because I think when I left home I didn't have mum's cooking.
"I never had breakfast so I just got so hungry by lunch time and would gorge on food then.
"My fiance Mark is a chef so people think that was why I got so big but it was the junk food I'd eat.
"I got so big I couldn't sit on the floor because it was so uncomfortable and worried I wouldn't be able to get up on my own so I just couldn't play with Freddie.
"I had been a size 18 since after I left school and got a job. I never had breakfast, and so gorged at lunch."
Emma, who lives with fiance Mark Jones, 33, in Shrewsbury, aims to drop below 10 stone before summer.
She added: "We go back to Crazy Knights now regularly and I don't get out of breath like I used I can keep up with Freddie. "Before it was exhausting but I didn't know anything else."
