I’ve been reading this thread for a while now, and totally understand
@Q007 ‘s need for some solid science, as a former research scientist, current science teacher and soon to be medic myself. Most of it seems anecdotal, doesn’t it? All these n=1 stories...
I’d really recommend reading Dr Bernstein’s Diabetes Solution, Q -
https://amzn.to/2HR4Yy5 Now while he is type one himself, he is a diabetes specialist doctor and treats all types of the condition. In his 80s now and still working with patients full time; his method has reversed most of the complications his 60-odd years of diabetes has caused. I’ve reversed all mine (there's that n=1 again!). His method involves eating low carb, high protein and moderate fat - 30g carbohydrates daily (split 6g breakfast, 12g each at lunch and dinner, mainly from green vegetables, which provide essential phytonutrients), plenty of protein and whatever fat naturally comes along with it - he’s not suggesting eating slabs of butter or blocks of cheese. I’ve improved my HbA1c from 89 to 40, and high glucose levels are thought to be much more dangerous to heart health than pretty much anything else.
Hope this helps.
