I am afraid this is the norm, not the exception. It is basically the NHS Eatwell Plate and is not far removed from what I was told. Much depends on the type of T2 course and who is running it, and that depends on the surgery/local commissioning group directives/ and what is available in the area. The X-Pert course is more enlightened and does cover low carb with extra fats in addition to other diets.
On diagnosis I was given a very glossy NHS magazine with pictures of the Eatwell Plate. I was told I could eat anything I liked in moderation as long as it was low fat and easy on the sugar. Moderation being portion size, not frequency. The only bit I remember about portion size was protein, which was about the same size on a plate as a clenched fist. Jacket spuds featured heavily, as did baked beans, as did fortified breakfast cereals. I went away with the magazine, no medication, and was absolutely delighted! I'd never had much of a sweet tooth so cutting down on sugary stuff was easy. I already ate breakfast cereals, wholemeal bread, baked beans and jacket spuds. I needed to change very little. I was not at any time told that carbs were the reason for raised BS levels. But for this forum and learning to eat to my meter I am convinced I would be on shed loads of meds by now, and probably insulin.
I am afraid there are many, many T2s out there exactly the same as your friend.
