This is somewhat related and quite interesting. http://www.nytimes.com/2010/07/20/health/nutrition/20best.html?ref=health http://www.nytimes.com/2010/07/20/health/nutrition/20best.ht... I have a similar issue. From what I can tell using my layman's understanding of the nutrition involved, fat or protein will give you steady energy throughout the day, but sugar or refined carbs (like white bread) will just temporarily spike your blood sugar and lead to much unhappiness a little later. Either way, if I don't pay attention to my energy intake, I don't necessarily get hungry - I just end up slouched in front of the computer accomplishing nothing without the energy to even get up and move. My thinking falls into repetitive ruts - I'll attack a problem from the same direction over and over, neglect any sort of creative solution, or even fail to execute a basic troubleshooting routine I should know applies. The article still seems to apply, though: being too full is really terrible for maximum motivation and really getting things done. It may be best to eat good, solid meals, but none of them too massive, and not just before you need to do hard work.
