Reversing Type 2 Diabetes

Reversing Type 2 Diabetes and ongoing remission

Public Information

Hear all about from Professor Roy Taylor the 5 minute summary.

Our research has shown that:
•   Type 2 diabetes is caused by a small amount of excess fat inside the liver and inside the pancreas
•   It is a potentially reversible condition
•   If a person has type 2 diabetes, they have become too heavy for their own body (nothing to do with the arbitrary concept of obesity)
•   Weight loss of around 15kg is necessary for most people
•   This can be achieved using a simple 3-step method: the 1, 2, 3 of diabetes reversal
•   Type 2 diabetes is most easily reversed to normal in the early years after diagnosis
•   How and why type 2 diabetes happens can now be understood

It is now being put into practice by both NHS England and NHS Scotland. The American Diabetes Association recognises remission of diabetes as an appropriate aim of management.

NHS England takes the research forwards

As a result of the new understanding of type 2 diabetes, NHS England is conducting a pilot scheme to determine the most cost effective way of delivering remission of type 2 diabetes: https://www.england.nhs.uk/diabetes/treatment-care/low-calorie-diets/

Preparing your own 800 calories per day diet is possible but challenging and time consuming. More information on this is given in the book ‘Life Without Diabetes’. Ready prepared fresh food providing a balanced diet of 800 calories per day can be ordered:

Background

All this work has depended upon a breakthrough in understanding.

We now know that type 2 diabetes is caused by excess fat inside liver and pancreas.

It all started with sudden coming together of research results from Newcastle and elsewhere. The Twin Cycle Hypothesis described how it might be possible to explain the cause of type 2 diabetes in a very simple way. Click here Reversing the twin cycles of Type 2 diabetes to read the description of this once the story could be told of what happened next. The highest scientific award from Diabetes UK – The Banting Lecture – was awarded for this, and this paper described what was said in the lecture, delivered at the Annual Professional Conference of Diabetes UK in 2012.

In 2008, Diabetes UK had given a grant to test the twin Cycle Hypothesis of the cause of type 2 diabetes. Proof of the hypothesis was published in 2011 as the study Counterpoint. The slides you will see on clicking the Counterpoint link show the data both from this, the most important study on what causes type 2 diabetes as well as the following study.

It was clear from that time onwards that type 2 diabetes is caused by too much fat building up within liver, then overspilling to the rest of the body - including the pancreas. This starts up a second vicious cycle inside the pancreas, with the fat actually switching off normal insulin production.

This second study – CounterBalance - showed that once the vicious cycles of type 2 diabetes had been reversed, the remission of diabetes was durable – as long as weight was not regained. Here is the scientific paper, published in 2016 in Diabetes Care: very low calorie diet and 6 months of weight stability in Type 2 diabetes

One of the most important discoveries is that of the Personal Fat Threshold. Type 2 diabetes is not caused by ‘obesity’. Different people have different levels of tolerance of fat within liver and pancreas. But if you have type 2 diabetes, you have crossed your ‘personal fat threshold’. If you lose weight and go below your personal fat threshold, type 2 diabetes is likely to disappear providing that you have not had diabetes for too long. Most people can get back to normal in the first 6 years after diagnosis, but it is never too late to try.

DiRECT

DIabetes REmissions Clinical Trial – understanding why significant weight loss results in remission of Type 2 diabetes is at the heart of DiRECT.

Once we had shown that type 2 diabetes was a simple condition of too much fat inside liver and pancreas, we needed to move on to discover whether this knowledge could be used for routine treatment of the condition. To run the large required, Professor Roy Taylor collaborated with Professor Mike Lean of the Professor Mike Lean, University of Glasgow to carry out the Diabetes Remission Clinical Trial (known as DiRECT). It showed:

  • One third of all people taking part were free of diabetes at 2 years.
  • Around three quarters of everyone who were in remission at 1 year stayed in remission at 2 years.
  • The group who embarked on rapid weight loss had fewer serious medical problems in the second year of DiRECT.

DiRECT results: Direct results at 2 years (PDF: 627KB) full paper and the online DiRECT Appendix (PDF: 499KB) are now available.

Scientific Information

The information on this page is for doctors and scientists. It includes slides on various aspects of the reversal of Type 2 diabetes as well as published papers.

  • Newcastle research has established that type 2 diabetes is caused by excess fat in liver and pancreas.
  • If this fat is removed in the first ~6 years of diabetes, functional beta cell mass gradually returns to a completely normal level over 12 months in most people.
  • The immediate loss of fat from the pancreas following weight loss is from a labile pool, and this is observed only in those with type 2 diabetes and not non-diabetic people.
  • The small, irregular pancreas typical of type 2 diabetes returns towards normal volume, and returns to completely normal shape over 2 years of remission.
  • Provided weight loss is maintained, beta cell function does not decline over the following years.
  • The UK consensus definition of remission of type 2 diabetes [link to https://doi.org/10.15277/bjd.2019.221] is an HbA1c <48mmol/mol (<6.5%) off all diabetes medication, achieved by weight loss and maintained for 6 month

Further information

In 2008, we published the Twin Cycle Hypothesis to explain the cause of Type 2 diabetes. This hypothesis predicted that diet could entirely reverse Type 2 diabetes. Read the scientific review, Pathogenesis of type 2 diabetes (PDF: 471KB) on the US National Library of Medicine website.

The Counterpoint study designed to test the hypothesis was funded by Diabetes UK. The results were very clear. Weight loss averaging 15kg (2 stone 5lb) achieved over 8 weeks caused two distinct sets of changes. Within seven days, liver fat had fallen by 30%, liver insulin sensitivity had returned to normal and fasting blood glucose had become normal. By eight weeks, pancreas fat content had returned to normal and insulin secretion by the pancreas had returned to normal. Read the full scientific paper, Reversal of Type 2 diabetes (PDF: 195KB) and the related Newcastle University Press Release, Diet Reverses Type 2 Diabetes.

This new understanding of what causes Type 2 diabetes and how it can be completely reversed has been used by individuals worldwide, a report has been published documenting practical management of Type 2 diabetes in respect of reversal (PDF: 85KB).  A review describing the beta cell de-differentiation (PDF: 1081KB) explains why the condition is reversible. Under the endoplasmic reticulum stress caused by excess intracytoplasmic fat, the cell goes into a survival mode and switches off specialised gene expression. Removal of the fat permits re-differentiation.  Scientists and doctors with access to the journal Diabetes Care, can read a full review of the science underlying this matter: Type 2 diabetes: etiology and reversibility (PDF: 363KB). See the more recent reviews:  Diabetologia Review 2017 a discussion of practical aspects of achieving remission. The most recent reviews are in Lancet Diabetes & Endocrinology and in Journal of Internal Medicine
