Anyway....I seem to be experiencing something unexpected.....
I'm cold ! My wife is comfortable and the room temperature is 21 degr (first time I turned on the heating today).
But I'm cold. Cold hands. Cold feet.
Could this be due to the diet ? I mean, I'm not burning anything....and of course I have a little less "isolation" 
I think i does, i mean a am not on diet, but also i dont have "the isolation" and i am always cold
warm your feet is the advice i can give, when your feet are warm, your whole body will feel warmer..
it sounds girly, but a footbath helps really good, and after that put on "geitenwollen sokken"

sorry dont know the english word for that (see the pic below for the non dutch people)
something like this i use, and it massages too
