> Curious on your take here - whenever I am very hungry I notice that my sense are acutely aware of any smell and are generally sharper (outside of the hunger part). Wouldn't that similarity translate to after a post fasted run that your brain is also much more acutely aware since it has been starved of food and is now trying to (in a historical sense) forage or hunt for food on a short term need? This seems to be normal and common when fasting. It happens to me personally and I’ve read comments from other people who experience it too.
