You are right to illustrate that I should have specified my fears are mostly relevant to Type 1’s and otherwise insulin-dependent. I too broadly use the term “diabetic”, when I mean other people metabolically like me.
I actually have no issue with nutritional ketosis in people not already prone to ketoacidosis. It is possible, but exceedingly rare to proceed to ketoacidosis just though a keto diet in HEALTHY people. I’ve only known one person, personally, (not Diabetic of any type) to do so, but he didn’t actually eat real food. He lived off of body-building shakes alone, with a single can of tuna once a week as a “treat”.
I do cringe every time I read about our ancient ancestors being in ketosis, though. For one, we have limited information on them, and “experts” can only speculate. They don’t even agree on estimated lifespans. How long do you think a diabetic could have lived then, anyway? Mortality rates of the youth were astronomical, only the fittest had the privilege to die of old age. It is unlikely that any humanoid ever existed on meat alone, either. Dental relics show we’ve always evolved as omnivores. They gathered nutrient dense fruit, nuts, ancient grains, and roots when they were available Ketosis is likely what got them through the winter and early spring. We’ll never be able to really know, only speculate.
You can’t cherry-pick data of ancient hominids, though, to draw a correlation to modern humans. None of us live in a hunter-gather society. They still exist, but not with the technology and internet access to join our discussion here. We have 12,000 years of evolution following the development of agriculture and a more heavily grain-based diet. We didn’t take well originally to agriculture, there is significant evidence of evolution to adapt and thrive on the new food sources. We have very different chemistry from our woefully-referenced predecessors. I’m happy to embrace the choices that improve the quality of you life, but please don’t defend those choices with misrepresented “fact”.
But again, I’m not disputing the use of keto in healthy people. I’m definitely NOT supporting a grain-based diet, either. I think it’s probably great for many type 2’s. Though I do think it’s popularity will fade in the near future as we learn more about insulin resistance and it’s causes and learn how to treat THAT rather than the symptoms.
So yes, I’m rephrasing my earliest sentiment to “keto for Type 1s scares the crap out of me”.
