You were talking about thermogenesis, now you're talking about different activity levels. Not the same thing at all, really.

You seem to be talking about some sort of very narrow non-motion definition of thermogenesis and I am not. I guess according to you, shivering because one is cold is not thermogenesis.

If you want to know more about what I'm talking about with drastic changes in calorie expenditure, do a google search on "non-exercise activity thermogenesis".
