Low-carb researcher Amber O'Hearn studies evidence emerging from covid-19. People are asking "Can low-carb diet help?", but interestingly she instead argues that we can learn something from covid-19 — not just the standard low-carb theory. mostly-fat.com/mostly-fat/202…
Disclosure: I helped a little with the research and writing.
Disclosure: also we used to be married.
I think the answer to the original question is, Yes, there are several reasons why low-carb/keto/carnivory might help with covid-19, and in any case it wouldn't hurt.
But, those reasons are obvious-in-retrospect to someone familiar with the topic. RQ! Of course! And metabolic syndrome comorbidity, of course! My read on Amber is that she's more interested in pushing the boundaries of human knowledge, so she spends the bulk of the article …
trying out explanations that would explain why people with metabolic syndrome *and* African-Americans are at higher risk, and arguing that both the mainstream auto-immune theory *and* the standard low-carb diet theory aren't sufficient. ៚
