As the learned judge said, it always pays to spell out the obvious.
Some things are better left unsaid. There may be good reasons for adopting a lower calorie diet for few weeks before switching to a sustainable way of eating for the long term.
I did. The
science page says this:
In 2014, some research was undertaken, (the DIRECT study), which showed that people who followed a rapid weight loss regime based on this low carbohydrate/high fat way of eating not only lost weight fast, but in doing so, cleared fat out of their pancreas and livers and were able to actually put their type 2 Diabetes into remission. A number of the study participants were able to stop their diabetes and blood pressure medication as a result of their weight loss and healthier lifestyle and the majority of them managed to keep the weight off longer term as well.
That statement is problematic.
The DiRECT study [managed programme]
This was a follow up to the Counterpoint study, c.2008, by Prof Roy Taylor and his team at Newcastle University. The Counterpoint study showed many overweight people could put their T2D into remission by losing around 15 kg or more following a very low calorie diet
[not a low carbohydrate/high fat way of eating] . The aim of DiRECT was to demonstrate that shakes like those used in the Counterpoint clinical trial would work in a managed programme delivered through primary care. This led to the current NHS Pathway to Remission which aims to treat 20,000 people a year. The latest results show 50% of those losing 15-20 kg achieve remission, and 55% of those losing more than 22 kg. I do not know what guidance on maintaining weight loss is provided.
The CounterPoint study [clinical trial]
Vounteers were required to stop medication on day 1 of the trial, to avoid hypos.
Key findings of the clinical trial included:
- Some volunteers were 'responders', typically the recently dagnosed; 'non-responders' tended to have been diagnosed several years ago.
- Blood glucose levels came down to normal levels in 7 days (responders)
- Excess liver fat reduced by about 30% per week (i.e. week zero, baseline, =>100%; week 1, 70%; week 2, 50%; week 3, 35%; week 4. 25%)
- Liver insulin resistance was much reduced after one week.
- After three months beta cells in the pancreas were waking up and starting to produce insulin again.
- Most responders achieved remission (<= 42 mmol/mol)
The CounterPoint study [self managed weight loss]
When the CounterPoint results were published, the Newcastle team received over a thousand emails from people who wanted to put their T2D into remission. Prof Taylor recommended a 'portion controlled diet' not the shakes
[and not a low calorie high fat diet]. Subsequently 77 people reported back on their success in sufficient detail to be included as subject in a published paper.
[The CounterPoint study, rather than DiRECT is relevant to Freshwell's target group, people who want to manage their T2D and pre-D for themselves.]
Optimum weight loss and maintenance strategies
After Counterpoint Prof Taylor called for research into optimum weight loss and maintenance strategies. It may well be low calorie/high fat strategies, possibly coupled with some form of Time Restricted Eating, are one such group. To my knowledge there has been no such research to date. However the latest dietary European and American advice for diabetics are probably good enough for distilling into media we can all understand.
[Have Freshwell collated any evidence to show their low carb/high fat approach is optimum in any sense?]
DiRECT [weight maintenance]
Recently published results show only 25% or so of participants
[not the majority] maintained their lower weight/state of remission after 5 years. Prof Taylor has reported a failure in primary care support as envisaged at the outset.
Self managed remission and weight maintenance
Self managed loss of 15kg plus 7 kg is hardly an experience I will ever forget.
[Nor do I intend to end up where 'I started or worse'. Time will tell as it will for all of us who have got their numbers back to normal or near normal]
