If that did happen, those people would've died off and not bred, hopefully. (Sorry not-quite ancestors!) Since you can live easily 30-60 days without food the body would need to be REALLY sparing about burning muscles and hopefully wouldn't go ripping up muscle to make extra energy it didn't need, just to release insulin and store it as fat.


But since insulin raises muscle synthesis bigtime, if the burning of muscle spikes insulin it could be a feedback loop that assures when dietary intakes don't provide enough protein, the body does everthing it can to boost muscle building and retention along with fuel storage... carbs into fat cells.
