A man who had been diabetic for 23 years put his condition in remission after losing almost three stone in just 12 weeks.
David Williams' health had suffered in recent years having undergone triple heart by-pass surgery in 2007 and having a pacemaker fitted.
The 67-year-old had always struggled with his weight, saying when he was a child he comfort ate and in adolescence he began to smoke and did not exercise.
Knowing he had to do something, over the years David gradually stopped eating red meat, gorging on sweets and gave up alcohol and also took up swimming.
But after not seeing any results his GP referred him to the Low Carb Program, the Liverpool Echo reports.

After joining a "12 Week Bootcamp", David saw remarkable results and was clinically diagnosed as being in type 2 diabetes remission.
When he took on the challenge, David weighed roughly 13 stone.
Just a few months later, he weighed nearer 10 and a half stone.
He said: "I began to get into the habit in my twenties of excessive drinking, leaving the pub at night and getting a takeaway, to munch watching the TV before bedtime.
"As a chubby, friendly type I had lots of friends but no serious girlfriends, as my overweight appearance and attitude led to being not taken too seriously, by myself and others.
"I have also been on umpteen weight management programmes that have had some impact but never enough to bring me below the 'obese threshold."
He added: "For the first time, through the Low Carb Program, a paradigm change has occurred, I am no longer 'obese', and I feel that, for me, permanent change is possible.
"I eat a great variety of food, including lots of leafy vegetables, chicken, cheese, berries and cream and fish that I do enjoy. I have learnt to cut down carbs to a low level and, remarkably, this works.
"In conclusion, if you do recognise any of my traits and life journey within your own experience, please do look for the signposts and follow them before you become diabetic, need major surgery or have to live with huge bags of medication or daily injections.
"Life can be much richer and more satisfying without the carbs. After all, life can be so much richer with fewer carbs and less medication. Do also be kind to yourself. There will be blips along the way, but they are just blips."
David now lives a full and active life, going ballroom dancing twice a week with his wife Angela, 68, and competes in crown-green bowling leagues four times a week in the spring and summer.
He also works part-time at a local educational institution supporting students towards a career as primary school teachers.
