All good but I think you’re somewhat missing the point of my post & the fact that I went out of my way to state I am not promoting a vegan diet. Let me boil it down a bit.
I could not explain why both long term vegans eating a “well formulated vegan diet” (as best as one can be formulated) and long term LCHF people eating a well formulated ketogenic diet, both looked similar in terms of BMI, body fat and metabolic health (see Loma Linda link/reference above) given the large amount of carbs in the vegan diet. This would at least seem to be in conflict with our hormonal theory of IR, which is the cornerstone of LCHF diets.
That caused me to look into possible ways to explain this conflict. Randle Cycle, while a possible contributing factor did not seem to explain it fully. This led me to the growing body or work regarding the impact on dietary nitrates upon metabolic health. Research like this:
Nitrate and Nitrite in Health and Disease%20through%20non%2Denzymatic%20synthesis.)
The rest you can get from the extensive info above.
Bottom line, as I’ve already said, I’m not telling anyone how they should or should not eat, only sharing what I’ve found which I think is both very interesting and well supported.
