From my understanding it's following a healthy diet but the trouble is most of the population don't, we're bombarded with temptation and adverts. So, when we meet a diabetic nutritionist they label a healthy diet as a diabetic one like it something different. This for me just complicates stuff and then once confident in eating semi healthy you're given a new word game and led into doubt. For me, it is un-necessary and complicated and tries to address the lowest possible point of comprehension of approaching healthy eating. Finally, the food offerings and diets given to diabetics just seem tempting like a bad airline meal.
To make it easier they give us a Thali like dish to measure meat (protein) and veg. So now it's portion based too
I personally don't go with ultra processed foods nor sugar dense (simply creating a hypo with absorption rates is doable but harder to calculate). A lot of weight gain is more associated with ultra processed vs. processed and natural products and high carb low exercise isn't the best way
But let's say that's common sense. If you can't exercise etc, then cut the carbs
Many have said there's no-one diet to fit them all. Indeed this rings true for me. With insulin resistance and planning a diet to fit metabolism changes, I can eat the same thing three times a day and inject less or more depending.
Another interesting thing is diet studies over a long period. There's only been 1 or 2 studies over 8 years ever published (I'll get the source later it's a recentish book I've not got to hand). Most have been 4.
So where does that leave diabetics if so called normal diets haven't been fleshed out as 'healthy for life'. Then there's the fatty French food diet which flies in the face of all other diets. So from what point of authority are nutritionists speaking from, or even us
Another thing is that with a lot of diets, after people relapse they end up putting on more weight and having more fat than when they started the diet. (I'll get the source and study)
Finally, the last factor is diet is one of happiness. Most forced diets fail with this factor, hence relapses and mortality and happiness seem to be more intrinsic to longer life than an un-happy one
All in all, there's a lot more unknowns than knowns for a long term diabetic diet as there's no study over the time I've had diabetes. I know for sure it's more of a personal rather than a holistic diet we'll be pursuing and also, more studies need to be done!
