The article states that the link between will-power and blood sugar is weaker than commonly accepted. "What about the glucose idea, which seems supported by so much science? Dr. Baumeister and Mr. Tierney describe studies showing that giving people glucose (in the form of a sugar drink) restores their willpower.

Sugar helps people only when they think that willpower is sharply limited. It’s not sugar we need; it’s a change in mind-set."
