As a T2 (with family genetics against me, but happy to accept that lifestyle probably caused earlier D than would have occurred anyway), the nutritional sid eis something that the medics cant seem to agree on, so it is no surprise that some folks get confused and give up checking.
I have been told various things to include:
Follow a low fat diet - with low fat meaning 10% fat or less
Most prople should have a plate that is half full of veg, 1/3rd carbs and 1/6 protein, but as a T2 I can swap the carb and protein potion round
Dont worry too much about carbs, just eat a balanced meal
Eat fewer carbs, but include them in every meal
Eat wholemeal rather than white (bread/pasta/rice)
The one thing I have never been advised to do is count carbs in anyway.
I have through DSN appointments, reading and this forum adopted a broadly lower carb diet, (except when running), and mostly kept the fat content sub 10%, excpet for the odd 'sod it day' of course.
If this dissertation leads to anyone becoming better educated, then it can only help, so crack on (but agree try to avoid the more tabloid headline style)
Good luck
