You've got a great sense of humor. And besides giving us free feel-good drugs and maintaining whatever we do to our weight through diet, we have to acknowledge that it does burn a few calories too, so negates a little bit of what we eat.
My friend walks everywhere, refuses to own a car even though we live in a public transportation dessert. She gains 10 pounds every summer eating the same, doing the same amount of walking, but in winter she has to walk in cold weather and so it burns enough calories that she loses the 10 pounds she gains in summer.
So it is part of the whole equation. I think the hardest thing to realize in a world where we have more than enough delicious choices of food, and need to do so little physical labor, we lose track of how efficient our bodies are, and how few calories we actually do need to maintain health.
