Good job
@Jo_the_boat I've read the lot and commend you. Well done for you 2 stone loss and lowered HbA1c. A few understandable typos (sorry I didn't think to note these, but I think 2 or 3). Love your points on the symptoms especially the technical names in brackets. Great reference of the huge (in a good way) Dr Sarah Halberg.
I agree with
@Bluetit1802 that Type 2's can also produce too much insulin which is basically ineffective due to "rusty" receptors on the cells.
Your point on not requiring carbs is fair enough, but I am not sure if you covered our body will make what is required in terms of glucose, even from protein. And that running on FAT (becoming FAT adapted is a viable alternative, that supports all bodily functions), perhaps a reference to Ketosis - Professor Noakes might be worth a mention here.
For me the jury is out on whether the NHS choices are good for the majority of non-diabetics after a full days meals and snacks. Take for example persons in the 40's and 50's who have "normal" blood sugars and HbA1c's, their pancreas have taken a battering on the current guidelines for decades and no doubt require greater levels of insulin to cover the "hit" compared to when they were in the 20's and 30's. Judging by the number of overweight, obese and persons with abnormal blood sugars but not yet diagnosed diabetes, I think it is logical that these persons are close to the diabetic cliff - Just my opinion - you might want watch these 2 (although gut bacteria is discussed so is insulin response with surprising results that all non-diabetics should watch):
I am not sure you covered that berries are low carb and the best fruit for a Type 2, along with lemons and limes.
Small point but my HbA1c was 134, you say up to 120.
Where you mention fasting, it might be useful to put a couple of links to the one and only Dr Jason Fung.
Where you mention Metformin issues, can you consider including the contra-indications with Kidney issues (very important as Metformin can lower function for some).
In your section on the millions with diabetes, you might want to point out that circa every 17 seconds someone across the globe is told they have diabetes.
I agree that all Type 2's are different, but I think it is possible to produce a dietary list that Type 2's can cherry pick from which could work for around 85%; I agree that some can't tolerate for example diary or might be allergic to a specific food, or don't like fish; but I feel we know enough to have a broad list.
Mainstream advocate Metformin, Sulphonylureas, Insulin, in any combination, sometimes Gastric Bands if very obese and rarely diet and exercise. Whereas the alternative routes are LCHF (or variations such as PALEO) with or without exercise (I think it is important to state that exercise is around 15 - 20% compared to diet and it good at the maintenance of weight and general health), Intermittent Fasting, Keto (explain the differences in carbs) and Newcastle Diet
