I agree with peers. Doesn’t Keto (for part of the year) worked for millennia for our ancestors?

  Most of our ancestors lived a fraction of the lifespans we do. So any argument based on “it worked for our ancestors” is flawed. “It worked for our ancestors” could be the beginning of an idea for research, but certainly does not take you much further than that.

    I agree with all you said but I also guess our ancestors mostly die from infection, hypothermia, viruses… certainly not from brain stop working because carbs deficiency. "You have to have carbs for your brain to run" doesn’t make sense. You have to have sugar in your brain to run, but that sugar surely can comes from fat as well.

  Some of our ancestors might have done keto some times, but I'm not sure most of them did most of the time? Humans are decidedly omnivorous, and most of them would eat whatever they could get their hands on, including plants and mushrooms (and sometimes honey!) etc.

    iirc the inuit had a diet mostly consisting of meat and fish, but - according to wikipedia - not even they were usually in ketosis.

  They also had carbohydrates in their diet. Meat naturally contains carbs. Pretending that the human body is misunderstood and that it worked very differently is a common pitfall of these discussions. Largely it was the same, with the amounts differing.

    Meat contains only insignificant amounts of carbs. The human body can convert protein to carbs (glucose specifically) but the rate at which it can do it is limited, and my guess is that if it can't burn glucose, a metabolically-healthy body will burn fat (rather than glucose made from protein) until the diet has been quite deficient in calories for at least 3 days.
