Xyzz is always mentioning the Swedish guidelines so what do they say ? Unless you can read Swedish, you have to put up with the translation and formatting errors though.

They specify 4 diets for which there is long term scientific evidence of effectiveness ( glucose/lipids/weight loss)
The Traditional diabetic diet. composition: fat :25-35%, carbs 50-60%, protein 15-20%
Moderate carbohydrate restriction composition:fat >40%, carbs 30-40%, protein>20%
Mediterranean diet, composition: fat 35-40%, carbs 45-50%, protein 15-20%
Traditional diabetic diet compostion with low glycemic index. fat :25-35%, carbs 50-60%, protein 15-20% (low GI carbs)
They also mention the 'Extreme low carbohydrate diet' for which there is as yet (this is what they say) no good long term evidence. They describe the diet mentioning that it may reduce post prandial spikes. They include with caveats (watching kidney function, using non saturated fats
Extreme low carb diet: >50%, carbs 10-20%, protein<30%
Now I like to use an 1800 calorie diet as an example. It was often used in the past for a 'typical' diabetes diet and as a post menopausal woman is about right for me. Others may need more or less, depending of gender and activity level.
For carbs this works out as
traditional and traditional low glycemic 225-270 g carbs
Moderate carb restriction 135 - 180 g carbs
Med diet 202- 225g carbs
Extreme low carb 45- 90 g carb
Remember this is not just starchy carbs and includes carbs from all sources including those in vegetables , dairy and fruit. Quite often I notice that people who don't have to count these carbs for dosing purposes forget that they exist.
The swedish diabetes plate (slightly modified in Idaho but can't find the original) looks something like this... and is incidently what they used in the diabetic education I had in France (though the low GI version) . My own diet at 40-45% carb seems to fit somewhere between a Med and a Moderate carb restricted diet with low GI! (definitions will vary :lol: )
I can tell you of at least one T2 on here that also sucessfully uses a similar model.
None of these diets would be normally labelled
high carb diets, diets with much higher levels of carbs have been tried including the legume diet mentioned by Hana. ( Theres a man on diabetes stories, started that one in the Oxford trial in the seventies, continued successfully with it for 20+ years... until his wife died and he didn't know how to cook the beans!)
These diets obviously have very low protein/fat content. Such a diet has been used in parts of India for many years ( mainly vegan high carb (67%)/high fibre )

Neal Barnard's vegan diet also has some evidence of effectiveness and that is 75% carbohydrate
