    Seems counterintuitive. Difficult for me to believe that over millions of years, evolution provided humans with the ketogenic "safety valve" - enabling us to survive even in a paucity of food resources (i.e., no plant based food available); yet paradoxically, the "safety valve" is so inefficient that the human machine requires substantially greater number of calories to keep going when in the ketogenic state??? :s

    Surely, such a poorly equipped creature would have died out long ago, right? :'(

    This is a perfect example of people not understanding keto. A balanced keto plan includes plenty of healthy plant-based foods. Replacing glucose with ketones as fuel, one needs to eat much less and can go much longer without food. If you are doing it right you eat when you are hungry and stop when you are full. After you are completely adapted the need to eat every few hours is gone.

    As per the bolded. This can't be exclusive to keto. I eat when I am hungry. I stop when I am full. I don't need to eat every few hours. I do not do keto...

    Same here.

    Granting that as true for arguendo, that would have the evolutionary implication that keto has some strong disadvantage that selects against being in it. Saving energy can get pretty cut-throat, having an economy mode that isn't killing the acceleration as the default seems odd.
    There's even evidence in Arctic people for a selection sweep against ketosis - yes, despite all the talk of Inuit diets by keto fans, Inuit rarely are in ketosis. Most of them have a gene SNP that encourages their body to stay out of ketosis, and this trait is highly retained in the population even though it looks like it tends to increase infant mortality rates.

    Do you know if the mongols had that too? I'm curious.

    Is there a Keto support group on MFP anywhere? I need ideas for snacks that won't undo my efforts.

    I'm only aware of the selection sweep for the particular SNP existing for Arctic populations.
    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4225582/
    In a recent genome-wide SNP genotype study of 200 Siberian individuals,3 the strongest signals of positive selection detected by tests for haplotype homozygosity and allele differentiation mapped to a 3 Mb region containing 79 protein-coding genes at chr11: 66–69 Mb in Northeast Siberian populations. Because of the limited density of markers in the SNP data, it was impossible to pinpoint the causative locus for the selection signal. Here, we sequenced the genomes of 25 unrelated individuals from the Chukchi, Eskimo, and Koryak populations (Figure S1, available online) with a mean coverage of >40× by using the Complete Genomics platform (Tables S1A and S1B).
    It seems that it is prevalent in their neighbors. I would think it reasonable for it to exist in populations living in the more frozen ranges of the Mongol population, but I don't have the empirical evidence to make a claim.

    It is interesting. I've read about this before. I wonder if it applies to first nations and mongols where the temps aren't as low - the grasslands - where they may get a bit more plant but still live as carnivores for part of the year.
