Dr. Daily, what do you think about this new iPhone app, which calculates the calories in food you're about to eat based on a photo you take, then lets you share the info on Twitter and Foursquare and also acts as a visual food diary? – Jessica, Natick, Mass.

Eat less. Exercise more. And spend less time staring at your iPhone.
