Part of the deal on the Cooking Light Food Lover's Social Diet, as I'm pompously calling this little effort, is that the MyFitnessPal and UP apps share progress with friends (or, in my case, with the board of advisors). At least they do if you allow that sharing. Folks can see not just whether you made your calorie goal today, but also exactly what you ate that led you to succeed or overshoot the mark. They see whether you ate 1,600 calories of balanced whole foods or stopped by Hardee's at midnight for a Thickburger and shake (not that any of us have done that).
I can go into Erin Clinton's diary and see that she had fat-free Chobani yogurt for breakfast, along with some Kashi cereal and nonfat milk, for a total of 278 calories -- and also that she walked 27,000 steps, which is halfway from New York City to Buffalo, I think. However, until five minutes ago she could not see that I ate two 
slices of 100-percent whole-grain bread with a tablespoon of American Spoon sour cherry preserves and a teaspoon of butter for, coincidentally, an identical 278 calories. Her breakfast had more protein (from the yogurt) and was probably better balanced.
I basically felt shamed into sharing my diary: If Erin's sharing, don't I have to? But it creeps me out a little bit. One person considering joining our effort said she was simply too private -- both regarding food and fitness -- to possibly share.
But, of course, a food diary is like any other diary that you know will be read by others: You can always lie to it. So far, the UP band does not contain a lie-detector algorithm... but I'm sure that's coming.
