    Funny story.

    I lost 50lbs and gained 50 lbs within a year.

    I can say, without a doubt, being fat definitely makes the air feel warmer. I don’t even think it makes sense, since your skin senses it. But hot damn if my house goes above 72F I have to keep towels around when I’m heavy

      It’s not just a fat or muscle thing. Those both contribute of course; fat insulates and muscle produces more heat. But the real player is the surface area to volume ratio.

      A bigger person has a lot more volume than they have a bigger surface area, and since heat is lost through the skin this has a major impact.

      Could it just be a weight thing? So not necessarily fat, muscle could also help.

      If you’re body is heating your whole body, the amount of heat added will increase linearly with volume. But your surface area, i.e. the skin, increases sublinearly with volume. So you get more heat per surface unit?
