Ok, but it doesn't actually say it causes a DHA deficiency, just that
conversion of ALA to DHA is reduced. Only in vegans is the suggestion
made that there *may* be a shortfall in DHA.

Again it doesn't say that. As described, it's not a negative feedback
mechanism where increased AA inhibits the enzymes, it's a feed-forward
mechanism where the precursors i.e. LA and LNA inhibit their own
conversion to AA or EPA/DHA.

Yes, but the blogger attributes the health to cutting out the carbs.
That was what his aim was.
