Possibly, but the implication here is that you aren't specifically exercising - you're just being more active as a byproduct of being in a different environment. The impetus to "reward" yourself for that behavior would seem to be lower. On days that I go to an office, I don't (consciously) base my lunch decisions on whether I walked, took the train, or used a car service that morning, know what I mean?
