You’ll make poor choices and turn in awful intellectual performances on an empty stomach.  Psychologists at Scotland’s University of Dundee put 50 participants to the test either 2 hours after eating or following a 10 hour fast.

 

Test results revealed that hunger triggers impatience, impulsivity, and a need for immediate gratification .  The well-fed were willing to wait over a month for a substantial reward while the hungry could only manage 3 days.

 

If you want and need consistent mental performance, start with a good breakfast and eat regularly.  The researchers add, of course, that you shouldn’t food shop when you’re hungry.
