And I wonder if it can be altered. I recall some work a while back done by researchers in the Antarctic, where they exposed themselves to extreme cold for short times each day (10 minutes I think). They found that after some weeks of this, their body changed in the way it dealt with cold, and they were able to be more comfortable in cold environments than their colleages. I seem to remember the effect lasting about 6 months. I always thought this sounded like a physiological change rather than a metabolic one. I wonder if the type of fat had any bearing. And I wonder how you'd find out. It's kinda impractical to cut someone open to check out their fat. Biopsies are not a great solution either, because it may change preferentially in certain places in the body. The poor subject would end up feeling like a pin-cushion.
