"yes it's not as simple as calories in/calories out, but calories are still the most important" : http://physiqonomics.com/calories/ http://physiqonomics.com/calories/ tl;dr: outrunning your fork is _prohibitively hard_. In my personal experience, weight loss and fitness are not orthogonal, but they aren't the same vector, either. In agreement with the NYT link, I exercise because I want to be fit, because I want to prevent injuries, because I don't like being depressed, and because I want to do the previous items until I'm 90. Personal vanity is real, but secondary.
