In my recent Food Management editorial column, In Praise of the Quantified Selfie, I commented on the increasing use of the digital tracking devices people are using to manage their diets, exercise and other aspects of their personal health. Apple Computer is also rumored to be working on a wearable device, perhaps one that adds new capabilities beyond those presently available (see link to the story about that rumor, also below).

This trend has clear implications for onsite foodservice programs: the larger contract management companies now often offer their clients systems that integrate the use of these devices with menu offerings, especially when clients have HR departments with well-developed wellness programs.

FM has reported on some of these uses several times (you can find the links to some of those stories below). But for those looking for more information on the technology and theory behind the so-called "Quantified Self" movement, we assembled the following set of additional readings.  If you have opinions or observations to make about the technology, we welcome them: if you are a registered user of the site, you can submit your comments at the bottom of the page...


A Road to Self Discovery

Gary Wolf, who worked with colleague Kevin Kelly to found the website Quantified Self back in 2008, contributed The Data Driven Life to The New York Times magazine in 2010. The movement has gained a lot more attention since then, but his lengthy article— Data Tracking: A Road to Self Discovery—remains one of the best introductions to the subject in that it delves deeply into the principles and psychology of self-tracking:

A Somewhat More Cautious Point of View 

Not everyone sees tracking technology as taking off as fast as the early adopters believe it will. This article from The Economist looks at both the technology's promise and its impediments going forward: Health and appiness.

How Feedback Loops Can Assist in Behavioral Change

If you look more deeply into why self-tracking technology works when it comes to changing behavior, it helps to consider the theory behind “feedback loops,” which are key to everything form the systems used to land commercial airplanes to the way psychologists use behavioral to help clients address bad personal habits.
In 2011, Wired magazine contributor Thomas Goetz explained how the four key stages of a feedback loop apply to efforts of managing personal behavioral change in Harnessing the Power of Feedback Loops.
More recently, Michael Traylor looked at how the concept can be applied to population health management on WebMD.

And Speaking of Behavior Modification Therapy...

It’s also useful to consider how rewards fit into the picture. While many people associate this idea with B. F. Skinner’s pigeon-pecking experiments, later theory in operant conditioning underscored some key principles that could bear on the way the most effective “loyalty rewards” programs are structured.
One of these is the idea of “extinction,” which, simply put, describes how long reinforced behavior lasts after the rewards are taken away. Psychologists exploring this discovered that stronger habit-forming behavior is formed if rewards are given out in a somewhat unpredictable way, using a variable schedule. Here’s a blog article by  Nir Eyal that touches on some of the implications this has for retail purchase behavior: Want to Hook Your Users? Drive Them Crazy.
