The glycerol in the fatty acids make
only a very small carbohydrate contribution
if it is converted by the body to glucose.
(5-10%), far less than actually needed, even
if the body happens to cut down expenses
whereever possible.

But if Kathleen had problems to stay in
ketosis as she or her husmand intended
the main problem may be that there isn't
enough protein to be converted to carb energy.
Especially if in the first days the actual
requirements are much bigger than these
40 gms, 180 gms.
So i just wanted to have checked if there is
enough protein eaten, which i doubt.
Or to include enough carbohydrate for the
brain and blood cells directly.

From time to time they may have been in

ketosis - since
body has this option it'll be working.
But not *stayed*. Inuit yes, homo erectus no.

I don't think that Inuit are a good example
for the millions of years humans and humanoids
emerged in tropical parts of africa.
Because zebras and gnus and antelopes are
*low* in fat.
And some carbs should always
be available in the tropics,
cancelling ketosis.
No snow in olduvai.

Nevertheless it seems that parts of humanity
went through the inuit-like bottleneck
of ice-convered europe (in winter)
for the years from about 35000bc to 10000bc.
IMO this is maily why ketosis works, and
why it is a valid paleodiet.

Fortunately we have good fat sources
(Inuit have too, !Kung have mongongo)
to nourish most of our body.
If not diabetic , i still can't see *why*
we shouldn't take up
our brains food *directly*.
We know how much it needs, if we don't try to
cut it down.

The necessary amount if protein in ketosis
looks rather high to me.
But not wrong... Whoever decides so.
