We're a week into 2014. How are your health-related New Year's
resolutions holding up?
If you're already off-track, you may want to consider some tips
from the field of behavioral economics. In recent decades, research
has shown that putting our money or our reputation (ego?) on the
line makes it much more likely that we'll achieve our goals,
including those for improving our health.
Last week, several behavior economists offered lists of their
favorite tips. If you're having difficulty sticking with your
resolutions, you may want to peruse those lists for ideas.
Fruit and friends
For example, Dan Ariely, a professor of behavioral economics at
Duke University, includes these two recommendations in his list for
Order an annual subscription to the Fruit Guy. By committing to a
weekly service that delivers fresh fruit, we make having healthy
food a reality. This approach has the added sweet side effect of
urgency. Every week when the fruit is delivered, we know all too
well that if we fail to consume the fruit in the next week, more of

with friends or co-workers for workouts. This kind of social
obligation is likely to hold you, and them, accountable to show up,
and once you have shown up, you might as well start sweating.
The importance of social support for following through on health
goals is also emphasized in a New York Times commentary by Dr. Kevin
Volpp and Katherine Milkman, who teach behavioral economics at the
University of Pennsylvania's Wharton School.
"You can achieve more by pursuing goals with the help of a
mentor," they write. "In a study co-authored by one of us and
reported in the Annals of Internal Medicine, patients with poorly
controlled diabetes were paired with patients who previously had
poorly controlled diabetes but had since achieved mastery over their
disease. The improvements in glycemic control achieved by those
mentored in this study were larger than those produced by many
Volpp and Milkman also recommend that you put some money on the
In an article in the Journal of the American Medical Association,
a team of researchers (including one of us) reported that over the
course of a 16-week study, individuals who were given the
opportunity to set aside money for forfeiture if they failed to lose
weight lost 14 pounds more than those in a control group. …
