NPR Books exercises a bit of willpower to look at a new book by John Tierney and Roy F. Baumeister:
The power to resist temptation — to pass up dessert, to endure an unpleasant experience, to defer satisfaction — is our “greatest human strength,” argue psychologist Roy F. Baumeister and science writer John Tierney in their new book, Willpower. The book delves into the science of our age-old struggle with self-control.
“The Victorians talked about this vague idea of it being some form of mental energy,” Tierney tells NPR’s Audie Cornish. “In the last 15 years we’ve discovered that it really is a form of energy in the brain. It’s like a muscle that can be strengthened with use, but it also gets fatigued with use.”
Whether you’re resisting a favorite food or completing a dreaded task, exercising self-control in different areas of your life saps the same mental energy source. Many dieters employ the out-of-sight-out-of-mind technique of hiding desirable food — and studies show there’s something to it.
