Inspired by Dr Mosley, Lorraine lost over 6 stone (38kg)

55-year-old Lorraine Kerr began her weight loss journey with The Fast 800 last summer. She was compelled to act after learning of Dr Mosley’s passing in Symi, the Greek Island she had returned from on holiday just days before. Now, less than a year later, she feels like a whole new person, losing 6 stone 5 pounds (40.3kg), reaching her target weight and fully embracing her healthier lifestyle.

Lorraine’s inspiration

Lorraine had always been an emotional eater and the sad loss of her mother and sister in a short space of time led her to turn to sugary food for comfort. It had started to take a toll on her health and she was told by her GP that she was on the path to pre-diabetes. Also suffering from IBS and fibromyalgia, Lorraine knew she needed to do something about her health. She had first heard about The Fast 800 when she listened to Dr Michael Mosley’s podcast, however Lorraine didn’t feel ready to make the step towards weight loss until hearing the news about Dr Mosley.

In June last year, during a Greek island-hopping holiday, she had just returned from visiting Symi, the same island where Dr Mosley had been staying when the news broke about the tragedy that unfolded. “It kind of galvanised me to stop dithering”, says Lorraine, “and in a way I felt like I wanted to honour him and all the work he and his team had done. So, I began The Fast 800 just a few days after that holiday.”

I found myself turning to sugary foods. It took a toll on my health and my GP said it had put me on the path to pre-diabetes.”

Lorraine’s journey on The Fast 800 Programme

Lorraine began with The Very Fast 800 aiming for rapid weight loss, and in the first 12 weeks alone she went from 14 stone 7lb (92kg) to 12 stone 5lb (78.5kg). This complete change of her eating habits kick-started her incredible weight loss journey. Before The Fast 800, Lorraine’s typical day consisted of:

  • Breakfast: Extra large Danish pastry from a bakery, coffee with cream and artificial sweeteners
  • Lunch: Steak pie, a packet of crisps
  • Snacks: Several chocolate bar snacks, biscuits, more coffee
  • Dinner: Homemade pizza or spaghetti Bolognese

The Fast 800 inspired Lorraine to embrace more vegetables, and specifically greens. “I always loved the kale recipes, in particular the Harissa Greens and Halloumi, which featured largely during my 12 weeks and since. I didn’t think I’d enjoy it, but I absolutely love it,” she says adding: “I found the first 12 weeks difficult at first. I was very hungry but absolutely determined and I knew there was an end to the very low calorie restriction.”

Now Lorraine’s moved onto The Way of Life approach and a typical day on her plate now looks a little more like this:

“I use The Fast 800 app to make sure I’m getting enough protein,” she stresses.

Turning her health around

Perhaps the biggest motivation for embracing her new lifestyle permanently is the huge improvement in Lorraine’s IBS symptoms. “The amazing thing was that within three days of starting the programme, my irritable bowel syndrome, which I’d suffered from for a couple of years, had vanished, and it’s never returned.”

Similarly, Lorraine has also found that her fibromyalgia symptoms have improved along with back problems caused by Coccydynia – permanent inflammation of the coccyx. “I used to get explosions of pain; sometimes so horrific I needed morphine. I haven’t had one since around the six month mark, so my weight loss has really helped with that too.”

Alongside her healthier eating, Lorraine also began regular exercise. She started slowly, trying out resistance training, HIIT (High Intensity Interval Training) and Pilates. “My fitness was very poor and I was struggling to walk anywhere because of my weight. I’m only 5ft and 1.5 inches with a very slight frame, so that was a lot of weight to be carrying around on a small person.”

It’s had a massive impact on my wellbeing and health, so I’m really looking to make this a way of life because the changes have been so good. That’s the whole point, isn’t it?!

Where is Lorraine now?

Today Lorraine has reached her goal weight of 8 stone 2 pounds [51.7kg]. After pushing through the initial effort, Lorraine felt motivated by the impressive weight she lost in the first couple of weeks. From there, she’s found that she has not only improved her chronic illness symptoms, she’s also now sleeping and moving better. She’s swimming in the sea regularly and finds the 15-minute walk to and from the beach, including a steep hill on the way home, easy. “I’m walking really quickly now. My body feels clearer and brighter. There are so many benefits,” she says.

Her family and friends have cheered her on from the beginning, including her husband and father, and she’s not looking back. Lorraine is now adamant that the dramatic changes The Fast 800 has brought to both her body shape and health are not something she wants to reverse. “It’s had a massive impact on my wellbeing and health, so I’m really looking to make this a way of life because the changes have been so good. That’s the whole point, isn’t it?! I will be sailing past Symi at the end of next week so will give a silent nod to Dr Mosley and his lovely family – I can say I did it, I feel great, thank you.”
