second thing is how does this account for pregnancy right now maybe now the latest data from john speakman and colleagues in science with all the double labeled water about three months ago maybe suggest that during pregnancy women's energy intakes don't need to go up that much but they still go up and so if humans have been reproducing for millennia where did all that extra energy come from if we were on the brink of starvation all the time and then the last thing i'll say is anybody who ever goes fishing knows that the idea that every animal is hungry all the time and is going to gripe grab every bite of food you throw in front of it is never been fishing
