Most nhs nurses (who do most of the treating if t2 diabetics) have no clue as to how to actually deal with the disease at little cost to the NHS, I.e. To go low carb.
Just moved, so annual check at a new surgery, nurse asked how I managed it as she saw I wasn't on medication. I said I did low carb, she was impressed. Ten I found out that she thinks that low carb means to eat a fistful of low GI carbs with EVERY meal. That will just make someone with diabetes get worse diabetes as it is carbs that are the problem!
So if the nurses follow the NHS advice they have to give patients 3 monthly blood tests (at cost), give them medication (at cost) and deal with their worsening symptoms (at cost), plus the patients don't lose weight.
Surely if it's as simple as eat hardly any carbs, you will lose weight and get back to normal sugar levels they need to see this and give this advice. If I had followed the NHS guidelines I would be the same weight and still be properly diabetic, not 5 stone lighter and with normal blood sugars.
