Open Future HealthDavid Unwin, FRCGP, NHS Innovator of the Year (UK)

Your sense of wellbeing is much better if you can make sense of your illness and have some control over it. Then you can be optimistic about the future.

Dr David and Dr Jen Unwin

Dr David Unwin has been a partner at the Norwood surgery in Southport since 1986 and a GP Trainer since 1992. He was elected to Fellowship of the Royal College of General Practice for his work in using hope as part of the consultation.

More recently, the Fellowship of the Royal College of General Practice list David Unwin, as both a RCGP National Champion for Collaborative Care and Support Planning in Obesity and Diabetes; and a RCGP Clinical Expert in Diabetes.

David was a finalist in the 2014 BMJ National Awards for Diabetes Team of the Year due to an innovative and collaborative approach to using a low-carbohydrate diet in type 2 diabetes, and mixing this with a positive, solution-focused psychological approach.

In December 2015, David was awarded the NHS North West Innovator of the Year.

Mature Onset Diabetes

I have looked after the same community for 30 years now. When I started in practice we called Type 2 Diabetes ‘maturity onset diabetes’ because it affected people in their 60’s and 70’s.

There were none under the age of 50, in our practice in 1987. Now in the same population we have 21 cases of Type 2 Diabetes in younger people – with an average weight of 245 pounds (111kg).

“For many years I followed the advice given by PHE (Public Health England) and Diabetes UK. “It didn't go well. - Patients really struggled to lose weight and their blood glucose remained high and many relied on medication.”

Five years ago I would have said the future for diabetes care in the UK was ‘hopeless,’ but now I have seen how much my patients can achieve with lifestyle change, that has totally changed my view of medicine, and the future treatment of diabetes.

Seeing the Light

Breads and cereals break down into surprising amounts of glucose as predicted by the Glycaemic index. I was surprised how much.

Even after I realised the glycaemic index of wholemeal bread was high, and that was a source of some diabetic problems; after 25 years of believing that wholemeal bread was good, I found it difficult to change my advice. So I can really sympathise with others struggling with change, and adapting to new ideas.

I spent 25 years nagging my poor patients about cholesterol in their diet and for whatever reason the results were very disappointing for all concerned. Now I concentrate on helping them radically cut back on all sources of sugar, whilst eating far more green vegetables. I have over a 100 patients with weight loss averaging 19 pounds (8.5kg).

"Three years of treating people with diabetes."

I ask new patients what they understand about Type 2 diabetes. I tell them the there is nothing about the disease that they can't be sort out for themselves, with a little bit of help. They have to be in control.

We ask they what their best hopes are for future? We talk about improving their well being and reducing to a minimum any medication.

It possible for diabetics to visit the doctor much less often, to have excellent control of their disease, and to have many extra healthy life years.

Each patient needs to decide, where they are now? Then, what's the next step to improved health, or to some other important goal they have in mind. That might be breathing better or walking better.

The Patient Tool Box

The best tool on the tool box is Hope, but hope supported by correct knowledge and understanding. That give people control over their disease.

Many people have no ideas where the sugar in their blood comes from. We give them a modified glycemic index, with all the carbohydrate foods lists as teaspoons of sugar. Suddenly they see what the problem is.

To succeed in the LCHF programme they need to do a lifestyle change. We put them into an 8 week educational programme. They need to learn how to shop differently, new ways of cooking, new ways of thinking about food, new ways of measuring what they are eating, and new ways of measuring their own health.

We encourage them to keep a chart of their progress.


Winning NHS Innovator Of The Year in March meant a great deal to me, I'm not sure a GP has ever won it before.

It was partly because our GP practice has improved standards of diabetic care while spending over £40,000 less per year on drugs for diabetes.

Dr Unwin commented: “This great result helps show what a rewarding job general practice can be when we work together with our patients for better health. Diabetes is a national emergency, my patients have shown that many will choose healthy living over lifelong medication and that the low-carbohydrate diet is one way to achieve that goal”

Much of this was by offering our patients dietary alternative to starting medications. An extra ‘innovation’ was helping people in groups of 20, assisted by ‘patient experts’ a newish thing in general practice.

Impact of the study

Reversing type 2 diabetes is challenging, but possible, and a low-carbohydrate diet requires less insulin to be produced, taking the strain of insulin-producing cells and reducing insulin resistance. Entering remission from Type 2 Diabetes is much more likely through a low-carbohydrate diet than eating moderate and high carbs, which necessitates further insulin production.

The impact of this study remains to be seen, but Dr. Unwin is optimistic regarding its significance. “The very fact that the BMJ agreed to publish shows great progress,” he wrote on the DCUK Forum. “On top of which partly because of the world wide low-carb community the article itself is currently ranked in the top 5% of published articles. It’s being read from Argentina to New Zealand.”

However, most medical guidelines in the UK do not recommend the diet. The NHS advocates eating relatively high-carb and low-fat foods, while Diabetes UK highlights a lack of evidence regarding the “long-term safety” of the diet


NHS and NICE say there is no cure for type 2 diabetes. This study is yet another example of how the low-carbohydrate diet can be influential in helping patients come off medication, usually completely.

While this study alone is unlikely to result in dramatic U-turns from Diabetes UK and the NHS, it is additional evidence that the low-carbohydrate diet benefits for people with diabetes.

Support from Other Doctors

Other doctors are watching what we are doing. Some are conducting their own studies. Some are concerned that the higher fat content of the diet will increase cholesterol and could potentially cause a heart attack. They are cautious. Nobody wants to do any harm.

I'm our own clinic, most of the staff are now also LCHF, and one obvious difference is that no biscuits are served at morning tea anymore.

The low-carbohydrate diet is continually gaining backing, especially through success stories posted in the DCUK forum. It was these accounts that originally left Dr. Unwin “impressed and moved” before his own experiment began.

"I try very hard to help all the doctors, dietitians and nurses who email me for information and estimate there must be well over 80 now in the UK trialling this approach. At a broader level we just finished filming for a TV documentary to come out in the New year."

In May 2016, Dr. Sarah Hallberg told us to ignore the guidelines and eat low-carbohydrate high-fat foods. “Carbohydrate intake is the single biggest factor in blood sugar levels and therefore the need for medication,” she said. “We are essentially recommending that they eat exactly what's causing their problem.”

A year ago launched a 10 week low-carbohydrate on-line programme. Amazingly so far 160,000 people have done it and the results are looking really good.
