So if somebody had a height of 188 cm, and weighs 70 kg with little muscle, but still have genetic dispostion for diabetes, aged, slept terribly and never exercised and ate a terrible diet, with lots of stress but as long as this weight is maintained with not to much percentage of the weight slipping into visceral fat,
as I understand the science he would not get diabetes in the future, and I cannot think of others factors that might contribute, except for of course some rare diseases medications and so forth, and the type 1.5 diabetes people are a whole other ballgame, but to me it is a reason why we have hundres of millions of diabetics today compared to 30 millions in 1980, and that is excess bodyweight.
As for data if the newcastle diet is a definitive cure, I agree with your sentiment, but the Michael Mosley book was packed with telling statistics and good anecdotes, I read it on kindle so I do not have all the references but I did 94 small noting points in my obesity notebook. and some were about durability of diabetes remission .Many people in the book have had a remission going into several years now, Mosley himself, just rounded 3 years, and Richard Doughty was still cured after his diagnosis in 2011 in the interview in the book, but the most telling this is the scientific paper that made Roy Taylor think about the link about weightloss and diabetes.
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1234815/
it is a follow up of 600 patients 15 years later, since their bariatric surgery, and by the roughly 150 people with diabetes, 120 were still cured,such a long time later. 98 percent of those prediabetic at start of operation were normal still 15 years later. If they had done a bmi and bodyfat scan case by case for those who still were in remission and those that got diabetes again, my guess woould be that weightloss and bodyfat would have been the single most important factor in determining who got it back and so forth.
You also have several others bariatric surgeries telling the same, especially swedish ones. Since bariatric surgery is more effective for weightloss than the standard scientific advise given about weightloss by the normal medical commnunity, You will find more batriac surgery papers having positive longterm results for diabetics, than either lowcarb studies or lowfat studies for the most part, so Roy Taylor is kind of unique in showing the great effect of weightloss, since he actualy made people lose weight, over a very short period of time.
Also I belive if you lose lot of weight you can live a very healthy life on either a very lowcarb, or a lowvegan diet, for life, but I have not really seen the scientific papers that it will never cause diabetes again, I just belive it according to the all the medical diabetes evidence I have seen, as long as weight is kept below.
And on a personal level, I have seen to many people having gone the lowcarb route, lost some weight, but not as much as they should, and as the years have gone by, 10 for instance, they need metformin and others drugs to control the bloodsugar who slowly creeps up. So I am not against lowcarbing, but I do belive the weightloss part is the more important part of it, so when somebody says you do have to eat lowcarb if diabetes is given, I disagree ,point out what I think is the evidence, and then let people decide for themselves. People should eat lowcarb if they want, but people should know it is not the only way( not saying you have portrayed it as such)
Also lastly twin studies with an nice anecdotal evidence to round it up.
http://www.diapedia.org/type-2-diabetes-mellitus/3104085122/genetics-of-type-2-diabetes an excerpt from this article.
However, the twin studies performed for type 2 diabetes provide very different estimates of concordance in twin pairs. For monozygotic twin pairs these estimates range from 36% in a study of Finnish twins
[2] to 83% in a Japanese study
[3]. Equivalent figures for dizygotic twins were 16% and 40% respectively. One of the most robust studies used 44 pairs of identical twins where one twin had developed type 2 diabetes. After following up for 15 years 76% of the initially non-diabetic twins had developed the condition
[4]. It is this contributor’s opinion that studies of heritability in type 2 diabetes are just too variable to provide a meangingful figure – it could be as low as 20% or as high as 70%.
In the last study 25 percent of the twins still had not developed it, and they were in old age then, if i Remember correctly. Had they performed bodyweight and bodyfat analysis again, this would have been the link between those who gained it and not.
Anecdotal evidence, meet the Daley twins from Boston, first article is from 2010, the second from 2015. In 1996 one of the twins, Paul, got diagnosed with diabetes at a weight of 220 pounds. The same year the other one, Tim, weighed 200 pounds, that is just 20 pounds difference between a diabetes diagnosis and not between monozygotic twins! He was pre-diabetic however, and he then lost 14 pounds more, which normalized his bloodsugar. In 2010 the first article they were 60 years old, so they got diagnosed at 46, 14 years later, one still has it, the other not.
The other articles is about the twins 5 years later, the diabetic twin now uses insulin, the non-diabetic is still non-diabetic having lost 25 pounds when he learned about his brothers diagnosis, and they are 65. To me this shows it is possible to keep diabetes away, despite age, but I think his fat threshold would be lower when he got to 75 than 65 as he is now.
So in my mind all the science points towards diabetes being curable, getting under the personal fat threshold is by far the most important, I do not belive a Lowcarb is a necesarry for diabetics, even though it is a totally healthy choice for people to have it as a lifediet if they are at a good weight, and I belive diabetes can ke kept away for life as long as you keep your weight under the personal fat threshold. This is against what many preach here, but I am going to say it regardless, because that is how I view the science, and also despite the fact that it may hurt the feelings of many. Diabetes and obesity are two of the conditions people probably feel most shameful about, and even if people technically brought it on themselves, most people do not know enough about the science of either, to be blamed,shamed or riduculed for having it, as well as living in a society that is primed for making people get both conditions, pushing you into it from all kinds of directions. My hope is just that I will be allowed to say these things, despite all of this, and then people can make up their own minds, forexample, is this post helpful for them or is just the ramblings of a mad man, and then they can decide for themselves, but I am going to say what I mean is right about diabetes in the most civil, respectful, unhafetul way I can, so people have the option to decide for themselves.
