Re:  louisgray.com: Fitbit: Virtual Badges Influence Real Behavior - http://blog.louisgray.com/2012...
"I have had two Fitbits and two Jawbone Ups since they came out. I lost the first Fitbit and broke the first Jawbone Up. I got tired of the Fitbit when I realized I walked the same number of steps and ate the same stuff, wrong or right, every day, and slept at 98% effectiveness most nights.  The Jawbone Up is easier to wear, but you have to tell it when you are sleeping, photograph your food, and it doesn't count movement that isn't walking (biking, yoga). Nothing produced behavior change, because I am impervious to social pressure. But then I went to a nutritionist, found out I was sensitive to dairy and beans and quit eating them. And I lost nine pounds easily. I geeked out over all those numbers for a while, but at the end of the day you don't change until you are ready." - Francine Hardaway
