When I took Psych 20 at the University of Western Ontario 31 years ago, we
learned that exercise helped you to lose weight but not primarily because of
the calories burned.  The theory was that your body's "thermostat" or
feedback mechanism stops you from eating when you have had enough to eat.
If you don't exercise, the thermostat stops working and you overeat.
Exercise then, helps the body to know when to stop eating.   As I recall the
Psych course, there was quite a lot of research to back up this theory.

It makes sense from a Paleo perspective.  Eating a lot allowed hunter
gatherers to put on few extra pounds as insurance against the inevitable
shortage which would come.  But a few too many pounds would make it hard to
run after your next meal.  So a sensible evolutionary rule would be: (1)
when food is plentiful without running it down, get fat; (2) when you have
to run around a lot to get your food, stay thin so running is easier.  In
other words, your body thinks you are exercising to bring home your food.
Generally, hunter gatherers sit around and talk when they don't need to hunt
or gather.
