I'm not really sure from this comment what your objection to counting calories is. Is it that you can't do it accurately? That seems to be implied by the second two questions. I haven't found that accuracy actually matter that much; mostly what's important is nominal calories over time vs. weight/other health indicators over time. If the number's not technically accurate, I kind of don't care. All I know is I roughly ate so many calories, my weight changed by x amount, and I can walk x far without getting tired. Over time, I can have a pretty good guideline for the number of "back of the box" calories I should be eating to reach my targets (which addresses your first question of "what range to target") You mention explicitly that most people won't do it over the long term, which is definitely relevant. But even doing it for a little while can give you a good baseline so you can at least make educated guesses as to what you're eating, which is especially helpful in the "food truck burger" scenario. I guess my point is that we all agree knowing roughly how many calories you're eating is good, but the only way I know to figure that out is to, at least for a while, literally count them. There's still a huge margin for error, of course, but if I didn't keep tabs on it by looking at the back of the box, I'd have no idea at all.
