I've always figured NEAT burns more throughout the day since 1 hour lifting burns like 200 kcal, and 3 mile run burns roughly 300 kcal.  Yes, you get some EPOC, but that varies depending on intensity.  Just standing vs sitting burns a bit more since you're having to flex at least your thighs.  The metabolism bit is just ignorance on nutrition and biology. Metabolism is just the change of one chemical to another, and everyone does it at the same rate, despite what fatties tell you.  A skinny person just has less mass to keep warm, so the fire burns smaller than the fat who burns twice as much to keep twice, or more, times the mass alive.
