Hanger and decisions don’t mix

Expert insight:

When you’re due for food, your blood sugar levels drop and hormones like cortisol and adrenaline are released, says Jennifer MacCormack, doctoral candidate in the psychology department at the University of North Carolina, Chapel Hill, who was not associated with the study. In turn, you're more likely to experience hanger, the perfect storm of stress, frustration, and anger.

Together, these effects may keep you from thinking clearly about the short- and long-term implications your decisions will have on relationships, work, finances—everything.

The bottom line: 

Try to avoid important meetings and big decisions on an empty stomach, including pre-breakfast. When you are hungry in those situations, even recognizing that it could impact your choices may minimize the effects, MacCormack says.
