Do fat people have lower average body temperatures than thin people?

We know that there's a great deal of individual variation in resting metabolic rate. One figure I've heard (sorry, no source handy) is 8 calories per day per pound at the low end of the range and 14 calories per day per pound at the high end. On average, people with low resting metabolism are likely much fatter than people at the high end of the range.

As far as I know, those at the high end of the resting metabolic rate range would be generating more body heat.

It could be a complicated topic, though. Fat people might have more insulation. That could raise core body temperature. It's also possible that people with high resting metabolic rate circulate blood closer to the skin surface, to radiate more heat. I suppose that could be detected with infrared body heat measurement. Like I said, it's a complicated topic, much more complicated than most people realize.

If possible, please help me understand this difficult topic better. If the basic research has not yet been done, please say so up front.

Comrades! This is a great question which many of you might have personal experience with, however our rules are strict. Please keep to scientific answers, preferably from people with some expert knowledge.
