Fern Britton’s weight loss secrets: How life-changing steps helped the This Morning legend, 68, drop five stone after years of dieting struggles
For most of her adult life, Fern Britton has spoken candidly about her struggles with weight — fluctuating between a size 22 and a size 12 while trying almost every diet under the sun.
But something quietly changed.
After stepping away from her decades-long role on This Morning and embracing a slower, calmer life in Cornwall, the 68-year-old TV icon has finally taken control of her health — and the results have left fans stunned.
Last year, amid swirling rumours about Ozempic, Fern put the speculation to rest.
“People often wonder when you’ve lost lots of weight whether you’ve done it naturally,” she told Woman&Home.
“And I can look at you and say, ‘Yes, I have.’”
So what really happened behind the scenes?
The Wake-Up Call That Changed Everything
A couple of years ago, Fern underwent shoulder surgery — a moment she now describes as the turning point.
“I thought, ‘I need to get my life back on track,’” she admitted.
“I need to stop smoking, stop drinking, get eating under control and stop lying in bed feeling sorry for myself.”
That brutal honesty sparked a complete lifestyle reset.
From the Sofa to 6.5K Runs
Fern signed up to the NHS Couch to 5K app — a gentle programme designed to turn beginners into runners.
By September, she proudly revealed she had run an astonishing 6.5 kilometres.
“I just did 40 minutes of actual running, with a five-minute warm-up walk and a five-minute cool-down,” she shared online.
“So 50 minutes all together, but 40 minutes running. I covered 6.5K — I can’t believe it!”
Lifting Weights, Not Excuses
Running wasn’t her only weapon.
Fern has regularly posted snaps from her home gym, lifting dumbbells and barbells with a beaming smile. In April, she posed in a pink long-sleeved top and fitted black cycling shorts — fans barely recognised her.
The Health Scare That Refocused Her Body
In a previous interview with HELLO!, Fern revealed that her determination to build strength followed a terrifying battle with sepsis in 2016 after a hysterectomy.
“My legs and arms are much stronger. My tummy is much stronger after four children and everything else my body’s been through,” she said.
“I was really close to dying — and yet you can still get up, go out, run and be strong again.”
The Sugar Cut That Changed Her Diet
Alongside running, cycling, walking and weight-training, Fern quietly overhauled her eating habits.
She cut out 80 per cent of her sugar intake.
“I started to think about what I was eating, which I had never done before,” she admitted.
Three sensible meals a day became her rule — especially while enjoying cycling holidays in Italy, where she shared sun-soaked snaps with her “Bike Buddies.”
“A glorious week in Italy with the Bike Buddies! Friendships spanning 20 years. Love you ladies,” she captioned one post.
Fans Left Speechless
The transformation sparked an outpouring of praise.
“Looking fire, Fern,” wrote one follower, while dozens more marvelled at her age-defying glow.
A New Chapter in Cornwall
Five years ago, Fern moved permanently into her Cornish holiday home, renovating it slowly “bit by bit.” The peaceful pace has also fuelled her writing career.
Her latest novel, A Cornish Legacy, is her 11th book — taking two years to write, double her usual time. Since the pandemic, she has released Daughters of Cornwall, The Good Servant, and more, proving her second act is only just beginning.
