Merely guessing that the top ones are carb bound is meaningless. If that guess is correct along with the theoretical position that you appear to be aligned with then the list should reveal a progression from top to bottom of demographics that have dwindling carbohydrate consumption. Of course, this is nonsense. Carbohydrates in dietary makeup is available.

Under scrutiny you will find a great deal of variation between carbohydrate consumption and the relative list of diabetes prevalence. One of the highest cohorts, Indonesia is well down the list while meat heavy Spain has double the incidence of diabetes than spud loving Ireland. Obviously, other factors are at play.
You're welcome to stick with the Youtubers. You are fully entitled to take that position. However, one must be careful when using the relativism argument. I may disagree with you but, if I'm with the data and you are not then the disagreement stands and you are wrong. Data at least has an anchor to reality that withers relativism and for this reason it should always be presented and then only the interpretation of the data should be debated.
Not really I have seen plenty of graphs of say America which show the progress state to state decade after decade. In the programme on fixing diabetes the 20% at risk of Type 2 is hardly to be sniffed at alongside the 1 in 16 already disagnosed. I'm afraid I respect your opinion but this for me does not compete with the YouTubers: Lustig, Hallberg, Fung, Phinney, Knoakes, Cumins, Fung, Erdosi, Bell, Berg, Teicholz, Mutzel, Stapleton, Stoppani, Zinn, Einfield for the sake of brevity I have stopped listing, safe to say this is where I trust what I believe, some are Doctors and Scientists who have studied tens of thousands, so I trust this education - your points are contrary to theirs (I am only quoting the ones I can remember who have videos online with the views I have learned). Again I invite you to search for the Change for Life UK Government advert, it admits that too much sugar turns to fat and can lead to Type 2. If carbs are not the root cause, why was it that on Type 2 Patient Conference course I attended yesterday out of 4 diabetic educators who discussed carb amounts one said the range per meal was 30 to 60 grams over 3 meals and another said 30 to 50, why would there be a new guideline minimum of 90 grams of carbs if there were no problems with the previous figure.
In addition for me it makes sense, to reverse Type 2 you restrict carbs and sugar, carbs and sugar stress the system more that the other macros and cause the biggest insulin response, so it is logical that carbs and sugar are the root cause. We can back on forth on studies and observations such as the prevalence in India and China . I could list real anecdotal accounts of persons in my wife's clinic of whom I type up the notes for, so have built up a mental picture of what they were eating pre-diagnosis, not to mention my own orange juice, grape and banana significant increase over the period of a month just prior to falling off the diabetes cliff.
As for Spain (and I will add Portugal), I have business interests out there and certainly in Valencia and Barcelona, in the mornings the locals open food places are mainly sweet pastries - obviously Spain is large so this might not be typical. I also go to Ireland a lot (I am not making this up, my wife's Mum and Dad live there), so I have been going there for around 10 years, every time we go out for a meal, chips tend to be offered with another carb on the plate. In the past just like in the UK meals were 2 times a day with hard yucker included, in this context I believe the body can handle moderate carb in take up to perhaps 65, which is the circa age persons used to get diabetes.
To say I am wrong, is strong, my view I that I have put forward is a heavily backed position - not my own, put your money where your position is and call out some of the names I have mentioned, perhaps Ivor Cumins. I have not seen one alternative for the correlations I have put, or reason for the causality of Type 2 from yourself, I am aware of inputs from steroids, statins etc. If you are correct then it should be possible to reverse diabetes on potatoes, rice, pasta etc. I have made enough points, so this is where I stop on this thread. It is not a position of rudeness, I am guessing your views have been honed over several years like mine, so you are just as convinced.
