Jake Caldwell: From low mental health to marathon mindset
After struggling with his weight for most of his life, dad-of-two Jake Caldwell reached a point where his mental health was suffering and everyday activities became difficult. From playing with his children to socialising with friends, his confidence had hit an all-time low.
Following years of yo-yo dieting, Jake turned to The 1:1 Diet and lost more than seven stone in just nine months. Since then, he was shortlisted for ‘Man of the Year’ at the 2025 Slimmer Awards, started running half marathons and is now preparing to complete his first marathon in aid of mental health charity Mind.
"Inactivity, poor diet and weight gain are all associated with a greater risk of mental health issues. Also, mental health problems inactivity, poor diet and weight gain are all associated with higher levels of inflammation. Two excellent studies show significant improvements in inflammation on The 1:1 Diet."
Aidan Pritchard: From struggling paramedic to proud groom
At more than 25 stone, paramedic Aidan Pritchard knew he needed to make changes for both his health and his family. Having struggled with a complex relationship with food from a young age, his weight gradually increased over the years.
Determined not to be the exhausted dad watching from the sidelines, Aidan started The 1:1 Diet. From the very first step, things began to change, and within seven months he had lost nearly seven stone.
Now, Aidan describes his journey as completely life-changing and is excitedly planning his wedding with a much brighter future ahead.
Barry McCann: From losing his driving licence to regaining his health
Following a life-changing motorbike accident in 2001, 60-year-old Barry McCann was left weighing just five stone. As he battled chronic pain and reduced mobility, the weight gradually returned, eventually leading to type 2 diabetes and severe sleep apnoea that resulted in him losing his driving licence.
Determined to regain control of his health, Barry joined The 1:1 Diet. In just nine months, he lost more than three stone, reversed his diabetes diagnosis, won the ‘Wellbeing Award’ at the annual Slimmer Awards in 2025, and no longer relies on a night-time breathing machine.
"Weight gain is one of (if not the) biggest risk factors for poor sleep, and poor sleep is a risk factor for weight gain, so there is a spiral people can get into here which is difficult to reverse. In fact, excess fat in the tongue and neck are thought to be the key physical cause of sleep apnoea.
We know that weight gain, followed by excess fat being stored in the liver and pancreas (and other visceral fat being stored in the body) is literally the cause of type-2 diabetes (as shown by further work from the DiRECT study). We also know that not only can The 1:1 Diet reverse prediabetes, so that people can stop the progression in its tracks and never get full-on type-2 (as shown in the PREVIEW study), but if you do find yourself diagnosed with type-2 diabetes, by far the best nutritional solution is The 1:1 Diet, with an average of 54% of subjects in studies able to reverse the disease (according to the DiRECT and DIADEEM-1 studies)."
Raymond Cunningham: From out-of-control habits to new lease of life
At nearly 25 stone, Raymond became breathless walking upstairs, struggled with aching joints and felt constantly low on energy. With his confidence affected and his health declining, he knew it was time to make a change. He started Step 4 of The 1:1 Diet in January 2024, and within a week his energy levels began to improve. With support from his Consultant, WhatsApp group and Facebook community, Raymond went on to lose an incredible 9 stone.
Seeing others on the same journey and sharing their ups and downs helped Raymond realise he was not alone. If he had a setback, he simply got back on plan. His Consultant regularly reminded him that success is not about perfection, but consistency.
Dropping from a size 5XL to a medium was life-changing. Raymond had more energy, no joint pain and, most importantly, renewed confidence. His wife, son and daughter were delighted to see him take control of his health and transform his life.
"Support has been shown in multiple studies to improve outcomes when pursuing any kind of behaviour change, including weight loss. We also accredit our Consultant support model with leading to long-term weight loss maintenance. In fact, no other diet has demonstrated such prolonged maintenance of 100% of weight loss over several years."
Mark Elliott: From crippling knee-pain to endless opportunities
Mark Elliott had lived with severe knee pain since childhood. The condition affected his confidence from school through to adulthood, leading to isolation, weight gain and poor mental health. By the time he needed knee surgery, he weighed nearly 21 stone and felt he had run out of options.
After years of unsuccessful diets, Mark began working with a 1:1 Consultant who helped him make lasting changes. As he lost weight, his mobility improved, his pain reduced and his confidence returned.
A year later and following successful knee surgery, Mark is pain-free for the first time in decades. He has rediscovered his love of golf and motorcycling, joined a gym, earned a promotion at work and found happiness in his personal life. What started as a mission to improve his health has given him a renewed sense of confidence and opened up opportunities he never thought possible.

Nathan Ranklin: From health scare to Man of the Year
Nathan found himself trapped in a cycle of drinking vodka and eating takeaways. By the age of 20, he was struggling to breathe at night and barely sleeping. His health became so serious that his doctor warned he might not reach 30 if he continued with his lifestyle.
Inspired by a colleague, Nathan began The 1:1 Diet and lost an incredible 17lbs in his first week alone.
After one year on the plan, Nathan had lost half his body weight, an astonishing 18 stone, and went on to win Man of the Year at the annual Slimmer Awards. Today, his life has completely changed and he’s looking ahead to a healthier future.
Joshua Storey: From comfort eating to confident mechanic
At 25 stone, mechanic Joshua Storey struggled with daily tasks at work, often unable to fit comfortably into the cars he needed to move. His weight also affected his personal life and confidence, something he had battled since childhood.
After experiencing bullying at school, Joshua became socially withdrawn and found himself trapped in a cycle of comfort eating. A family friend eventually recommended The 1:1 Diet.
With the support of his Consultant, Joshua quickly began noticing changes in both his energy levels and confidence. After 11 months, he had lost an incredible 10 stone and described joining the diet as the best decision he had ever made.
"Comfort eating is generally the result of daily habits around eating behaviour and associations between the smell and appearance of food stimulating the desire to eat, even when the person isn’t hungry. Getting the support to become aware of the difference between physical hunger and cravings (appetite) is the key to successful, long-term behavioural change* "
Mark Barry: From 4XL to M in nine months
Man of the Year winner Mark Barry avoided baths and showers when he was at his heaviest because it meant walking past a full-length mirror. His weight was having a major impact on both his confidence and his relationship with his partner, Wayne.
Mark started The 1:1 Diet in October 2021 and by July 2022 he had lost more than 10 stone with the support of his Consultant throughout the journey. His transformation inspired Wayne to join the plan too, and the couple are now looking forward to a happier and healthier future together.
