Reading all your responses makes me so despondent for diabetics. In the UK they believe there are possibly 4 million with diabetes, and maybe 1 million are undiagnosed. This is costing the health service billions. So surely it is in the interests of the medical profession to get as informed as possible to ultimately reduce the numbers. But ... it is not in the interests of the drug companies who will lose billions if people become informed and use diet to put their diabetes in remission. So I think that perhaps drug companies put pressure on doctors to prescribe - and of course doctors do not have the time to give lifestyle advice, it is quicker to prescribe. But this is not moral or ethical.
My other point is that many people do not want to change their WOE and/or do not have the knowledge they need to make informed choices. This chap that I spoke to yesterday didn't have a clue, and didn't want to (or couldn't comprehend) consider a different WOE. "Potatoes are a big part of my diet, meat and two veg man, me". So what can you do with people like that? Well, I believe if doctors told diabetics that they are "carbohydrate-intolerant" (just as they tell coeliacs they are gluten-intolerant) and that eating carbs could ultimately kill them, perhaps more people would make the changes necessary. But then it comes back to Big Pharma again .....
