I believe it probably has that affect both purely psychologically,
but also through neurotransmitters - seratonin? not sure. I read
something about this awhile back.
But beyond that, exercise affects the insulin/glucogen axis
(lowering insulin, a promoter of fat storage, and raising glucogen,
which stimulates fat to be released from storage), in fact, some
people hypothesize that the hormonal affects are much stronger than
any calorie-burning ones when it comes to weight loss.
Here's a quote from a medical school metabolism handout I found on
the Web:
***
Nonetheless, the goal of identifying methods for tissue-selective
regulation of insulin effectiveness remains an intriguing
possibility. Exercise may accomplish this goal. If so, then the
effect of exercise to cause loss of adipose mass may arise in part
from regulation of insulin action, and not calorie consumption.

I'm interested exploring, among other things, the way
hyperinsulinemia and hypothyroidism interact, because it appears I
have both (among other things).
Sorry for barging in without an intro, I'll try to get to that
tomorrow. :-)
