THE SURPRISING ROLE OF BLOOD SUGAR
Psychologists have found that when people’s blood sugar levels fall, their willpower falls, too. Similarly, people who have hypoglycemia—the predisposition to low blood sugar—are predisposed to have chronically low willpower.
Example: A Finnish study found that prisoners’ glucose (sugar) tolerance levels predicted with 80% accuracy whether the prisoners would commit violent crimes again after release.
Sugary foods provide a quick spike in blood sugar and willpower, but this soon wears off. To boost willpower over a longer term, regularly consume foods that are low on the Glycemic Index, such as vegetables, nuts, raw fruits, fish, lean meat and poultry.
