Haha made me chuckle, but you are onto something in that the problem can be narrowed down.ducknald_don wrote: ↑Thu Jul 15, 2021 9:31 amI wonder how much weight hunter gatherers put on in good times and lost in lean times. My guess is not very much compared to the strategic reserves most modern people seem to accumulate.
I am conducting a personal experiment now where I try to go down from BMI 24 to BMI 21 and see what the difference in general performance and well-being is (not a very controlled experiment and largely based on introspection, but nevertheless). I guess the 1kg fat reserves for someone with BMI 21 are different from fat reserves for someone with BMI 24. And maybe the well being and performance difference of have/not have the 1kg fat are going to be much greater that carrying 8000kcal on one's body 'just in case'.
