Yes, that's right, and it's the same for any weight loss any T2 diabetic achieves. Put it all back, as often happens after a diet (as in yo-yo dieting), and your T2 will return.
As you know the DiRECT approach was to study the feasibility of rolling out a managed programme based on the Counterpoint study that proved that T2D was a reversible condition. It is not so well known that, after publication of the Counterpoint results, the Magnetic Resonance Centre at Newcastle University received a thousand or more people interested in reversing their condition. Many succeeded on their own initiative and Professor Taylor and his team published a Short Report on the outcomes.
Here is the opening paragraph:
Publication about reversibility of Type 2 diabetes using avery low energy diet (the Counterpoint study [1]) was followed by over 1000 enquiries from people with diabetes. The overwhelming sentiment expressed was profound relief at the possibility that the condition was not inevitably permanent. The extent of public interest prompted the authors to make available on a website general informationabout reversing diabetes, both for people with Type 2 diabetes and healthcare professionals [2]. In this, it isexplained that a very low energy diet was chosen in the research study to mimic the effects of gastric bypass surgery. However, steady but substantial weight loss achieved by reducing portion size was recommended as the preferred method. The focus was on the need to achieve substantialand sustainable weight loss through the best approach for that individual. All individuals were advised to discuss their plans for energy restriction with their own doctor, particularly with a view to adjusting anti-diabetic medication. A separate document with information for doctors was available. No alterations to habitual physical activity levels wereadvised. Within a few months individuals began to feed backtheir personal experiences of attempting to reverse their diabetes. We have collated this information, which provides a unique demonstration of what is achievable by energy restriction in motivated individuals outside a research setting.
... and the concluding paragraph:
These data demonstrate that intentional weight loss achieved at home by health-motivated individuals can reverse Type 2 diabetes. Diabetes reversal should be a goal in the management of Type 2 diabetes in these individuals.The durability of the effect on glucose metabolism requires further study. Long-term avoidance of weight gain must be the top priority after reversal of diabetes, and the dietary regimen best able to achieve this must now be established.
Establishing the 'dietary regimes best able to achieve long-term avoidance of weight gain' not only for the New Dawn managed programme but also the many T2 diabetics and pre-diabetics who want to do it themselves. I'd suggest a 'concerted action' drawing together all interested agencies and experts could achieve this.
