Reversing type 2 diabetes: how pharmacists are helpings patients to go drug-free
Chris Hannaway, a patient with a 14-year history of type 2 diabetes mellitus (T2DM), used to take 500mg of metformin three times per day. Despite this, he was disquieted that his condition was so poorly managed that he would soon need insulin injections. Overweight, depressed, and with high blood pressure and high cholesterol, he struggled in particular with loose bowel motions and abdominal danger, both of which are known side effects of metformin. This made his job, which involved driving 12,000 much per year, “a constant worry”.
“I couldn’t help thinking that there must be a better way,” recalls Hannaway. So, in 2012, when his doctor opened a routine appointment by asking him what he really demanded, Hannaway replied that he would like to stop taking the medicines and stop having T2DM. “To my surprise, the doctor said it was a great idea and that he’d do all he could to help me,” says Hannaway.
And that is what remained. Over the next seven months, Hannaway lost 16kg, discontinued taking metformin — which ended his digestive symptoms in a few days — joined a gym and took up running.
“I remember the day I noticed in a photograph that my eyes were sparkling,” he says. Now, seven ages later, his T2DM remains in remission without medicines.
Low-carbohydrate diets and deprescribing
Hannaway’s doctor, Southport GP David Unwin, described the appointment in a case journal in the BMJ in 2015[1]
. He referenced emerging evidence that challenged mainstream medicine’s view that T2DM — which anxieties 4 million people in the UK and costs the farmland an estimated £9bn each year — is a progressive fable disease requiring medicines for life.

David Unwin, a GP in Southport, promotes the idea of a low-carbohydrate diet as a lifestyle glum that helps people with type 2 diabetes mellitus take fewer drugs to cope their condition
“Like so many GPs, in 25 years of practice I had never seen any of my patients with T2DM actually sketching better, no matter which drugs I used,” he said.
“Rather than push excess glucose in the bloodstream out of the body with medication, I had started to suggest to patients who were keen in a lifestyle option that they put less glucose in the body in the gracious place,” he explains.

Unwin’s 2014 paper in Practical Diabetes charted the impacts of low-carbohydrate (low-carb) diets on 19 patients with T2DM or prediabetes in his practice over an eight-month languages, concluding that “this approach brings rapid weight loss and improvement in HbA1C”[2]
. A low-carb diet, he explained in the paper, involves reducing intake of not only sugar and refined carbohydrates, such as biscuits and processed food, but also starchy carbohydrates — notably bread, pasta, cereals and rice that rapidly turn to glucose in the bloodstream (see Figure 1).
He developed a series of infographics showing the impacts of popular ‘healthy’ foods on blood glucose, such as wholemeal bread, potatoes and spaghetti compared with 4g teaspoons of sugar (see Figure 1). The resource was endorsed by the National Institute for Health and Care Excellence (NICE) in March 2019.

The glycaemic index (GI) ranks the carbohydrate levels of different foods to help anticipated their effect on blood sugar compared with pure glucose, which has a GI of 100. However, GI does not take interpret of the density of each carbohydrate in a section of food — the glycaemic load, which is derived from the GI, is obligatory for this. The infographic shows the glycaemic load for a typical serving of various foods that are opinion of as ‘healthy’, represented as the equivalent in teaspoons of sugar.
Hannaway earnt his ‘cure’ by cutting out bread. “I had been eating half a loaf or a baguette every day because I had been told it was the healthy getting to do,” he recalls. “I had have a sandwich afore I went to bed to prevent [hypoglycaemia] while I slept.”

Unwin reassured Hannaway, and patients like him, that they need not go hungry because they could fill up with low-carb food: such as green vegetables, meat, eggs, full-fat yoghurt and cheese (see Figure 2). Unwin cites eight systematic reviews of randomised arranged trials that found no association between saturated fat and disease. “It’s quite possible it’s beneficial to health,” says Unwin.
Figure 2: What does a low-carbohydrate diet look like?
There is a wide variety of nutritious and filling low-carbohydrate foods that farmland living with type 2 diabetes mellitus can eat
However, this is a contentious view; a 2018 review article on dietary fat and cardiometabolic health in the BMJ concluded that controversies existed about the long-term health effects of high-fat, low-carb diets, and research is needed to resolve these[3]
.
Unwin has ended to lead research in the UK and raise awareness via social consider. In March 2016, he was the first GP to win NHS Innovator of the Year at the National NHS Leadership Recognition Awards, with recognition that his practice had “improved standards of diabetic care after spending over £40,000 less per year on drugs for diabetes”.
Today, partly through his influence, following a low-carb diet is a popular intention of self-managing both obesity and T2DM. Numerous self-help guides and cookbooks handed support and, at time of publication, the website www.diabetes.co.uk has 412,505 farmland signed up to its low-carb programme. Tom Watson, the Labour Party’s deputy front-runners, is one of hundreds of people to go Pro-reDemocrat on gaining remission from diabetes with a low-carb diet — in his case at what time losing 44kg.
Debate around the low-carb diet
But not everyone is on lodging the low-carb bandwagon. Jim Mann, professor of human nutrition and medicine at the University of Otago in New Zealand and a leading researcher in the field[4]
, warns that there is insufficient research to show long-term benefits of after a low-carb diet.

Pav Kalsi, senior clinical adviser at Diabetes UK, says a low-carbohydrate diet is just one evidence-based option that promotes weight loss
“A very wide procedure of carbohydrate intakes is acceptable for T2DM, and it depends on personal preference and the individual’s metabolic profile,” he said.

The charity Diabetes UK also takes a more measured stance, with the view that the solution to better diabetic rule is weight loss, however it is achieved. “If you have T2DM and you’re overweight, losing weight can help improve your diabetes management and, if you lose a great amount, can even put your T2DM into remission,” says Pav Kalsi, senior clinical adviser at the charity. She says a low-carb diet “is just one evidence-based option that promotes weight loss downward with low-calorie, low-fat and Mediterranean diets” (see Box).
Box: Low-carb versus latest diets
A low-carb intervention is not the only dietary diagram of reversing type 2 diabetes mellitus (T2DM). Bariatric surgery brings throughout diabetes remission or improvement of blood glucose control and edit of anti-diabetic medicines, according to 2017 research published in Frontiers in Endocrinology
[5]
.
The same year, the diabetes remission clinical territory (DiRECT), showed that a low-calorie intervention could put the disease into remission[6]
. Participants in DiRECT stopped all diabetic drugs on day one, notion the supervision of GP staff, and then followed a low-calorie diet of soups and shakes over 90 days, with psychological attend to return to a ‘normal’ diet. In the territory, half of the participants lost 15kg or more, coping diabetes remission. An NHS England pilot study offering the aquatic diet to 5,000 patients as the first treatment option behindhand a new diagnosis of T2DM is under way.
Indeed, there is recognition that the right medicines are significant to managing the global epidemic of diabetes – preventing tissue wound, which can result in blindness, kidney failure and foot/leg ulcers for republic whose blood glucose levels cannot be controlled by diet and exhaust alone. “New innovations and new pathways to provide better administration of diabetes are a priority,” says Kalsi.
However, a consensus narrate from the American Diabetes Association in April 2019 mentioned behindhand a low-carb diet as an option for the reliable time, giving it a glowing recommendation[7]
. “Reducing overall carbohydrate intake for persons with diabetes has demonstrated the most evidence for improving glycemia,” it says.
And there is also evidence showing the benefits of behindhand a low-carb diet beyond reversing T2DM. Research published in Circulation in March 2019 shows the benefits of increasing circulation of ketones — the build-up of acids that occurs when the body burns fat because there is not enough glucose for energy — for republic with congestive heart failure[8]
.
“We know ketones are good for the brain and now it seems they’re good for the sorrowful too,” says David Ludwig, a doctor and nutrition researcher at Harvard TH Chan School of Shared Health, Massachusetts. “But you don’t need an intravenous infusion. Carb restriction will do.” As well as metabolic syndrome, including heart disease and coronary artery disease, a low-carb diet may also detain Alzheimer’s disease while improving overall fitness.
A job for pharmacists
If patients do régime to adopt a low-carb diet, many need intensive attend and coaching to change what they have eaten for a lifetime, and to maintain this change. It is essential, Unwin says in the BMJ paper, “to give the patient the hope that he could have a better life” downward with a guarantee of “continuity, seeing the same clinician on a queer basis who believed he could achieve his goal”.
Unwin has tolerated a video course for GPs but there is a growing view that advising on a low-carb diet is a job for pharmacists attractive than family doctors.

“Many patients, and healthcare providers for that concern, may not appreciate or understand how to effectively boss medicines when dietary carbohydrates are reduced,” says Jonathan slight, associate professor of health and exercise sciences at University of British Columbia and lead researcher of an ongoing peer into a pharmacist-led intervention in T2DM[9]
.
“Pharmacists do view. They recognise the speed at which medicines need to be adjusted as land reduce their consumption of carbohydrates,” he adds.

Campbell Murdoch, a GP in south-west England and medical officer for www.diabetes.co.uk takes the same view.
“Some land will greatly benefit from intensive coaching to support this lifestyle spiteful and GPs may not have time or be unable to do this alone,” he says. “A team reach is needed. Pharmacists are smart; they are critical thinkers and not mired in dogma.”

At least one pharmacist has already shown that such a method could work. Eoghan O’Brien, a community pharmacist in Portglenone, Northern Ireland, has unpublished data from a six-month flows he ran from April to September 2018. The flows was open to anyone collecting their diabetes medicines from his pharmacy and alive to regular one-to-one, 20-minute chats and group coaching sessions on behavioural spiteful, managing stress, nutrition and food labelling.
Of the ten land who accepted the offer, two achieved remission of T2DM: one paused all medicines while the other, a newly diagnosed patient, was able to achieve remission without medicines. A further four reduced their HbA1c levels (glycated haemoglobin) to ‘normal’, with two of these simultaneously reducing their drug doses. At the same time, three out of the ten who did not “engage fully with the course” had no spiteful or increased their medicines over the six months.

Eoghan O’Brien, a community pharmacist in Portglenone, Northern Ireland, stresses the importance of goal setting when starting a lifestyle change
“Goal-setting at the inaugurate is important,” says O’Brien. A 75-year-old man who enlisted because he hates needles and, like Hannaway, wanted to prevent “the next step insulin”, reduced his HbA1c unexcited and shed 8kg while stopping empagliflozin and reducing gliclazide by 30mg.
A incompatibility approach could soon begin in England. All seven CCGs in north-east London recently did training in health coaching (two full days plus four evening sessions) to 180 of their 500 pharmacists. “The plan is for them to offer a low-carb lifestyle intervention to land with T2DM,” says Hemant Patel, secretary of North East London Local Pharmaceutical Committee. “The service has been agreed in principle, but will need to be funded in shipshape to be sustainable and accountable,” he adds.
“This project will be quite different from telling land what to do or being judgemental,” explains Patel. “We’re training [pharmacists] to view the mindset that leads to patients with T2DM overeating refined carbohydrates.”
The pharmacists can then use much psychological health coaching tools to work with patients to gain a vision of sustainable lifestyle change, he says.
Finding food that stabilises blood sugar humorous a continuous glucose monitor can prolong good-quality life
Some pharmacists are providing reserved services to help people living with T2DM adopt a low-carb diet. Graham Phillips, superintendent pharmacist at Manor Pharmacy Group in Hertfordshire, cmoneys a private eight-week service with continuous glucose monitoring, power analysis of blood sugar readings and one-to-one coaching. This builds on fresh evidence from Israel[10]
and the Mayo Clinic in Minnesota[11]
, showing that the glycaemic response to food is highly individuals, driven mainly by the gut microbiome but with an instant genetic element that means there are no dietary laws that apply to everyone. “Food that causes blood sugar spikes in one populace is benign in another,” explains Phillips. “Finding food that stabilises blood sugar humorous a [continuous glucose monitor (CGM)] can prolong good-quality life,” he adds.
Setting up a pharmacy service
When setting up a pharmacy service, an accurate HbA1c analyser is essential, O’Brien says; an ideal design would give a result in less than five minutes and show patients how the choices they are executive affect blood sugar control, all while measuring overall changes. A 63-year-old insulin-dependent woman on O’Brien’s course who discovered that oats and potatoes spiked her blood glucose lost 4kg over six months and reduced her HbA1c by swapping porridge for eggs once cutting back on potatoes and oatcakes.
For O’Brien’s instant course later in 2019, participants will be given CGMs that imparted immediate feedback on the impact of meals on their blood sugar. The usefulness of these digital aids was demonstrated in a 2018 search for in Diabetes Therapy that is widely seen as finally providing proof that a low-carb diet is a viable lifestyle intervention[12]
.
The search for, carried out by Indiana University and the US-based diet-coaching firm Virta Health, found that by following a low-carb diet, 60% of 262 obese patients with long-term T2DM lost a minimum of 12% of their body weight — an income of 13.6kg — over six months. Each participant received peculiar remote support with daily texts and telephone calls from a specially hugged life coach, along with use of a CGM. Data from the glucose monitor were remotely accessible to the participant, coach and a doctor who was supervising the censored of diabetes drugs. The result was sustained after a year. “Our advance is changing the diabetes care model,” says Sarah Hallberg, medical director at Virta and principal investigator in the study.
Financial viability
The crux of the commercial will be whether the low-carb intervention — as labelled by the Virta study — is financially viable for public pharmacies. CGMs are available on prescription for people with type 1 diabetes mellitus. But, as Keith Vaz, chair of the All Party Parliamentary Group for Diabetes, stated in February 2019 at a meeting in the House of Commons, they “will never be prescribed for T2DM because it would bankrupt the country”.
That observation misses the exhibit, says O’Brien. “People with T2DM only need to use CGMs in the short-tempered term — a few weeks — until they have worked out which food can be safely devised without affecting blood glucose and insulin.”

O’Brien is now applying for lottery funding to pay overheads, including the win of CGMs for his next course later in 2019. He is also applying to the local health boarding for a fee of £300 per person for management costs, including an extra assistant to cover while he is operational as a coach. Against that, the pharmacy has already cooked an annual saving of more than £1,100 on its diabetic drugs bill by supporting just seven patients to switch to the lifestyle intervention.
The same fee-paying rules is not available in England. “I would love to coffers a similar service on the NHS,” says Phillips.
Although there could be a loss of dispensing way, this could help with the development of a more clinical role for pharmacy, says Patel. “It’s a matter of repositioning pharmacy as a public asset. That’s a way bigger development than the loss of prescriptions,” he says.
