Mary, here is a guess: I think that the problem may be low blood
sugar, causing an increase in adrenal activity, activating the
"fight or flight" response.
With paleo and other low-carb diets, we try hard to keep blood
glucose levels low, so that insulin levels will not rise. I think
it is possible that in some people, blood glucose levels can
occasionally fall *too* low on this kind of a diet. I have no
idea whether this is a matter of individual variability or
something more systematic. To speculate: if the diet makes
extensive use of saturated fat, and saturated fat increases
insulin resistance, and ketones also stimulate insulin release,
then insulin levels could become elevated, pushing blood glucose
levels *way* down.
I have experienced some symptoms of increased adrenal activity
while on a ketogenic diet recently, such as hot flashes and
palpitations.
But this is sheer conjecture.
