Lisa Riley’s transformation has prompted a wave of reaction online — but what changed, and why is the Emmerdale star celebrating it now? See the before-and-after images she posted and the surprising reason she credits for the change.
Mandy Dingle: A long-running part of Emmerdale
Lisa Riley is best known to viewers as Mandy Dingle, a character she first played in 1995. Mandy arrived in Emmerdale alongside Zak and became a familiar face at the Woolpack, later running a short-lived burger stall called “Mandy’s Munchbox.” Over the years the character has been at the centre of several dramatic story arcs, cementing Riley’s place in the soap’s history.
In the show’s timeline, Mandy’s relationships — including her marriage to Paddy Kirk after an earlier marriage to Butch — have allowed the storyline to explore both comedy and heavier drama. Most recently, Mandy played a supportive role when the family faced the fallout from Bear’s disappearance, a plot that touched on issues such as modern slavery and criminal cover-ups.
What the transformation shows
Away from the soap, Riley has been sharing updates about her personal life. On social media she posted a pair of images that chart her change in appearance and fitness. Her captions were measured and upbeat: she used clapping emojis, described taking a moment to appreciate herself, and said she could now see what others have been seeing when looking at older photos.
Riley publicly thanked Village Gym, noting she is proud to be an ambassador for the chain. She framed the change as part of staying active and preparing for a milestone birthday — she turns 50 in July. Her tone on social media was one of quiet pride rather than dramatic boastfulness, and she invited fans to celebrate the progress with her.
How has Emmerdale’s Lisa Riley lost weight?
Lisa first decided to overhaul her health almost ten years ago.
Back in 2017, she began keeping a detailed food diary, noting everything she ate and drank each day.
She cut out snacks completely and stuck to a healthy breakfast, lunch and dinner, which helped her lose 12st within a year.
At the time, Lisa explained: “I decided to lose weight for me. I just did it for me and I was patient. It is down to consumption.”
During her time on I’m A Celebrity…Get Me Out Of Here! last year, Lisa opened up further about her journey.
She told Jack Osbourne she had stopped drinking alcohol after previously consuming up to three bottles of wine a night.
“I genuinely could not cope when my mum died. I got to the point I couldn’t turn my brain off and the wine suffocated everything,” she said.
Lisa is now more than ten years sober.
While in the jungle, she admitted her weight had increased again, revealing in November 2025 that she was a size 16 to 18.
Since then, she has once again slimmed down.
In recent weeks, Lisa has shared updates about her routine, including swimming, Zumba classes and personal training sessions.
“I love the gym!” she said.
Her dedication has clearly paid off!
