Information for your doctor
It is important that you discuss the management of your diabetes with your own doctor. It will take years for this new knowledge to become incorporated into textbooks and guidelines, so your doctor may be wary of information from the internet. Therefore, here are some notes for you to take to your doctor.

Our work has shown that type 2 diabetes is not inevitably progressive and life-long. By identifying the cause of the condition it has been possible to design appropriate management. We have demonstrated that in many people who have had type 2 diabetes for up to 10 years, major weight loss returns insulin secretion to normal.

It has been possible to work out the basic mechanisms which lead to type 2 diabetes. The Twin Cycle Hypothesis of 2008 has been tested and found to be correct. Too much fat within liver prevents normal insulin action and too much fat within the pancreas prevents normal insulin secretion. Both defects are reversible by substantial weight loss.
A crucial point is that individuals have different levels of tolerance of fat within liver and pancreas. Only when a person has more fat than they personally can cope with does type 2 diabetes develop. In other words, once a person crosses their personal fat threshold, type 2 diabetes develops. Once they successfully lose weight and go below their personal fat threshold, type 2 diabetes will disappear.
Some people can tolerate a BMI of 40 or more without getting diabetes. Others cannot tolerate a BMI of 22 without diabetes appearing, as their bodies are set to function normally at a BMI of, say 19. This is especially so in people of South Asian ethnicity.
Award of major grant
In October 2013, Diabetes UK announced the award of its largest research grant ever. It builds upon the breakthrough in understanding the pathophysiology of diabetes and the related demonstration that short term Type 2 diabetes could be reversed to normal. This is brought together with work conducted in Glasgow on use of low calorie liquid diets in primary care.
The study aimed to answer two main questions:
- Can type 2 diabetes be routinely reversed in Primary Care?
- Is the long term effect of this intervention better than conventional treatment?
The study is known as DiRECT (DIabetes REmission Clinical Trial). Participating general practices in Tyneside and Scotland will be randomised either a) to use the low calorie diet followed by an intensive weight maintenance phase, or b) to best possible care according to current guidelines. In order to deliver the low calorie diet, together with the critically important backup and support, primary care staff will be trained by the study team (8 hours structured training followed by ongoing support).
The expertise of academic staff at Glasgow and Newcastle will be combined. Counterweight was formed as a company in order to keep together the expertise developed during the Counterweight Project which has been highly successful in achieving and maintaining weight loss in the primary care setting.
Study volunteers in the Newcastle area will also undergo detailed magnetic resonance investigations coupled with metabolic tests to examine further the basic mechanisms which bring about the return to normal blood glucose control. Additionally, detailed psychological assessments will be carried out to understand the response of individuals to this management approach and identify factors which effect adherence.

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.
A clinical 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.

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.

The first year results of DiRECT were presented at the International Diabetes Federation (IDF), (5/12/17) meeting in Abu Dhabi and have been published in The Lancet. DiRECT Year 1 results and supplementary appendix
The study shows that around half of people with type 2 diabetes of duration less than 6 years can reverse their condition and remain in 'remission' after 1 year.
The pathophysiological basis of reversal of type 2 diabetes is described in a major paper: Taylor R et al.
