Neuroscience research has come up with reasons why 88% of all resolutions fail as explained by Jonah Lehrer, the author of “How We Decide”. The part of the brain that keeps us focused, handles short-term memory, and solves abstract problems is called the prefrontal cortex. In general, willpower is weak, so when the prefrontal cortex is overwhelmed, the brain starts to give way to temptation. As you probably know, the more tired you are the harder it is to resist what you want.
Not only does overloading the brain make willpower difficult but also a brain not properly nourished. Studies show that self-control tasks require more energy through caloric intake than those activities that do not require willpower. Since weight loss is such a popular resolution it is important to not starve the brain as it may impact behavior. Smart eating is better than not eating.
(Did You Know? Many individuals with better willpower do so not by showing restraint but by focusing their mind on something other than the activity that they are to avoid according to Walter Mischel at Columbia University.)
Lastly, there’s hope for all of us because the prefrontal cortex can be exercised. Practicing mental discipline in one area can improve others. Ultimately, this makes it easier to resist temptations including holiday sweets!
