I currently think it does matter what the type of diabetes is.
There are two types essentially: Type 2, where there is plenty of insulin, at least at the beginning, but that insulin can’t be used well.
Type 1 (slow or rapid onset), where there is inadequate insulin.
The line may blur between the 2 in some cases. And then there is MODY… which is a different and variable kettle of fish.
If type 2 is a disease of very high, but ineffective insulin, then the approach should be to find ways to increase the insulin sensitivity. Simply forcing even higher levels of insulin (though drugs or injected insulin), may compound the problem as the insulin levels are still high. To put it simplistically, reducing insulin resistance involves a combination of insulin sensitisers. exercise, low-carb/keto diet, weigh normalization. I used to believe that just normalizing blood sugars should be enough for type 2, now I believe that normalizing blood sugars and insulin levels should be key.
For type 1, the appropriate treatment is replacing the absent insulin, and making sure it is used well and insulin resistance is prevented (insulin sensitisers, diet, exercise, etc, etc.).
The general lifestyle approach for both is similar , but the underlying rationale and focus is different. Medications may be different, though not always.
My 2c. I’ve been reading a lot of Dr. Fung, The Art and Science of Low Carb, keto literature etc. lately, and my way of thinking has changed.
I have also seen some very dramatic reversals of type 2 diabetes, when major lifestyle changes were made, and weight loss also achieved. We have people with a1cs in the double digits reduced to normal levels, and medications being stopped / reduced. Not all see such dramatic benefits for type 2, but I’ve seen enough cases in the last few months to be totally convinced of the importance and probable efficacy in most cases, of aggressive lifestyle measures.
