Keep Your Belly Full
It’s not that you don’t have enough mental fortitude to pass on that bear claw; the need for willpower may be driving the craving. Although there isn’t consensus, some scientists believe sugar is willpower’s fuel, pointing to the crazy amount of energy—in the form of glucose—the brain uses for smart decision making. Don’t start a challenging task on an empty stomach. Keep blood sugar stable by eating carbs, including grains, beans, and fruit, throughout the day.
