Neuroscientists often report that, although we have only one brain, we have two minds: one that works impulsively and seeks immediate gratification and another one that controls our impulses and delays gratification until we meet our future goals. When these two minds have competing goals, we face challenges related to the strength of our will. The writer and health psychologist at the University of Stanford, Kelly McGonigal, says strategies from her book entitled "The WillPower Instinct: How Self-Control Works, Why It Matters, and What You Can Do to Get More of It" and her themes include diet and weight loss, health, addictions, smoking cessation, temptations, procrastination, stress, exercise, self-remorse and shame. I will continue my essay by indicating some studies and their results.
People behave differently when they 've ingested calories recently as opposed to when they haven 't. Less hungry organisms might be more patient, less punitive, and better able to concentrate on a task before them, for instance. This should seem intuitive to all of us who get really grouchy when we haven 't eaten in a while (as in the hungry people in commercials from the clever series of Snickers ads) and makes a lot of sense from the standpoint of thinking about how to design an organism that has many possible priorities. Hungry organisms should be expected to behave differently from full ones, generally shifting their attention and energy toward getting food, to the exclusion of other priorities.
