Annabelle Stemp always struggled with her weight and as a child was referred to a slimming group.
By the age of 19, she was wearing size 20 clothes.
Annabelle said: “I had lots of friends but never had a boyfriend.
“I didn’t really want to go out because I was called the fat one or the ugly one.”
It was when Annabelle moved to Market Rasen that things changed.
“I decided to join the local Slimming World group and I have never looked back,” she said.
“It isn’t a diet, it is a change of lifestyle.
“Now, I can walk into a shop and pick up a size 10 or 12 dress and it is amazing.
“Losing the weight has boosted my confidence as well.”
Annabelle, who celebrates her 25th birthday today (Wednesday), has trained as a Slimming World consultant and opens her own group in Market Rasen this Saturday.
She said: “I want to help people and give them a new lease of life, no matter what their age.”
The group will be held in the Methodist Church schoolroom at 8.30am.
