Eat (and Sleep) Your Way to Willpower

This post is based on the book “Willpower:  Rediscovering the Greatest Strength” by Roy Baumeister and John Tierney.  Glucose depletion can turn the most charming companion into a monster.  The advice of eating a good breakfast applies all day long, particularly when you’re  physically or mentally stressed.  If you have a test, an important meeting, or a vital project, don’t take it on without glucose.  Don’t thrash out serious problems with your partner just before dinner.

Don’t skimp on calories when you’re trying to deal with more serious problems than being overweight.  If you’re trying to quit smoking, don’t try quitting while your also on a diet.  You might even consider adding some calories, because part of what seems to be a craving for a cigarette may actually be a craving for food once you’re no longer suppressing your appetite with nicotine.  When sugar tablets were given to smokers trying to quite, sometimes the extra glucose has led to higher rates of success, particularly when the sugar tablets were combined with other therapies such as the nicotine patch.

When you eat, go for the slow burn,  The body converts just about all sorts of food into glucose, but at different rates.  Foods that are converted quickly are said to have a high glycemic index.  Included here are starchy carbohydrates like white bread, potatoes, white rice, and plenty of offerings on snack racks and fast-food counters.   Eating them produces boom-and-bust cycles, leaving you short on glucose and self-control, and too often unable to resist the body’s craving for quick hits of starch and sugar from doughnuts and candy.

To maintain steady self-control, we’re  better off eating foods with a low glycemic index.  Included here are most vegetables, nuts (like peanuts and cashews), many raw fruits (like apples, blueberries, and pears), fish, meat, olive oil, and other “good” fats.

When you’re sick, save your glucose for your immune system.  Before driving to work when you’re sick consider this:  Driving a car with a bad cold has been found to be even more dangerous than driving when mildly intoxicated.  That’s because your immune system  is using so much of your glucose to fight the cold that there’s not enough left for the brain.

Sleep when your are tired.  We adults routinely shortchange ourselves on sleep with the result of less self control.  By resting we reduce the body’s demands for glucose, and we also improve its overall ability to make use of the glucose in the bloodstream.  Sleep deprivation has been shown to impair the processing of glucose, which produces immediate consequences for self-control, and, over the long term, a higher risk of diabetes.
