I think you hit on the key issue at the end there, the ammount of activity people have in their lives. I dont have a problem with fast food as long as one's lifestyle can accomidate it. Also, not all of us are in highschool and have access to school lunch. for my money, something off of the dollar menu is about as cheap as it gets. As with anything, we need to practice moderation in all things. Hell, even water can kill you if you drink too much.
