A mum-of-two who shed more than 10 stone after joining a Barbican slimming group has just completed her first extreme fitness event – and says she’s never been healthier.

Rebecca Sadigh, who weighed 24 stone in 2016, took on a 5km Tough Mudder challenge on Saturday, scaling a huge cargo net and crawling through muddy tunnels along the way.

“It was really good,” she said. “I’m still aching from it.”

The 30-year-old, of Old Street, decided she needed to lose weight after her youngest daughter got stuck in a play area at the Sobell Leisure Centre in Finsbury Park.

Rebecca said she was unable to climb up to rescue the one-year-old and was embarrassed to have to ask another parent to step in.

Since then she’s twice won the “greatest loser” award at her Slimming World branch in Lever Street, which goes to the slimmer who has lost the most weight in a year. She’s also won a variety of peer-nominated awards, including “woman of the year”.

She told the Gazette: “They all look at me for help and I’m always happy to help anyone.

“I’ve been big my whole life and I’ve been bullied my whole life for my size, so if I’m able to help one person then I would do it in a heartbeat.”

Rebecca hopes her success story will inspire others make healthier lifestyle choices. Cancer Research has just launched a national obesity campaign, saying excess weight is the second biggest avoidable cancer causer in the UK, accounting for an estimated 22,800 cases per year.

“I would never have expected to be able to do anything like this,” she added. “A couple of years ago I could barely walk, let alone run.

“My fitness levels have gone through the roof and I love exercise. It’s crazy.

“I’m now able to run around after the kids, my energy is up and most importantly my health has improved. I’m no longer on any medication.”

Meanwhile, her BMI has dropped from 60 to 27.6.

“My blood levels are all normal,” she said. “Before, I was on the verge of diabetes and I had really high blood pressure.”

Rebecca’s Slimming World consultant Maxine Smith, 45, said: “Everybody is so immensely proud of her. It’s incredible what she’s done.

“I actually remember the first day I met Rebecca. She was really quiet but now has so much confidence. She helps so many other people, passing on good advice, giving people healthy recipes and tips.”
