Yay for neurologically challenged people. What does that have to do with evolution and ketosis which was the original question i responded to that you glossed over.

Did I go too fast for you?
No, i was responding to MEversbergs question about evolution and ketosis. You brought up her book and i called her what she is and nowhere did i use the word "only". My comment about what does that have to do with MEversbergs question was in response to your reply that she deals with neurologically challenged people (you).

As for the majority of our evolution being in severely cold climates, thats just complete bull. Listen PB, i know your personality and facial features may suggest a hard life in the arctic but im quite certain not you or anyone else here has Inuit ancestry.
Now what about the original question. Would these ancestors living in severely cold climates be in ketosis or would that not be possible without downing sticks of butter and lard?
Quick question. Would not significant caloric deficit even in the presence of "excess" protein lead to a ketotic state? Seems likely to me. That may not have much to do with what is being discussed now, but there were some thoughts on harsh environments and the need for lots of fat to be ketotic.
I've never tried measuring my ketone levels so I don't really have an N=1 to tell me what protein does at different levels when I'm LC.
There is a reason why people naturally gravitate towards warmer tropical climates. It's ideal for sustaining of all life. Have you forgotten there can be no life without the sun? Ketosis = darkness, stress, winter, opposite of the sun. You age terribly due to that fact(Jimmy Moore anyone?)
Ketosis symbolizes starvation; the human body is resilient and does not want to die so easily, so it gives you all these neat tricks in order to keep you alive a little longer. It's not meant to be anything other than that though, and no one has ever proved otherwise. Random trials and abstracts that show the benefits of ketones does not prove the benefits of ketosis and until something shows me that beyond a shadow of a doubt ketosis is superior for longevity, beauty, cognition, I'll keep eating like a "hummingbird".
If they're only eating one major meal per day, then fat metabolism is already activated,
Even lean animals have quite a bit of fat if you eat the whole animal, marrow, brain, skin etc., which they most certainly did.
If pickings are slim, plant wise, minimal fruits & tubers and they had to rely on edible vegetable matter, which is fermented in the lower intestine to short chain fatty acids.
Then highly likely they would be in Ketosis even in a warm climate without the aid of butter or lard.
Even though their overt intake may be lower in fat, this is compensated by the aditional fat derived from bacterial fermentation of vegetable fibres.
This makes me wonder about mountain gorillas who ean mostly leaves and grass, which is low in sugar content anyway, do they experience ketosis.
You can be in ketosis without eating extra fats. You can be in ketosis with eating nothing at all.
Being in ketosis means the body is using fats as a fuel source, be it dietary or body fat. So to answer the question, yes you can be in ketosis without downing sticks of butter and/or lard.
High PUFA fat intake is a good way to make a stressful state even more stressful.
