waider | maybe I'm just a medical oddity

There was something-or-other - more than one something-or-other, if I recall correctly - floating around in the last few months about how all the "exercise to lose weight" advisories were based on some utterly flawed research in the first half of the 20th century. To be honest, I forget the specifics, but the key argument was that if you go and do some exercise, you burn energy, and your body raises the HUNGRY flag in order to get some fuel to replace that energy. And once you start eating, you'll probably overdo it, and thus Exercise Makes You Fat (or so went the something-or-other, at least).

Which fails to account for the fact that on gym nights I often find myself with no real appetite for any food, much less more food than usual.

Mind you, anyone who watches the dial on the treadmill will be aware that your non-professional exercise isn't particularly great at burning off calories anyway. I'll typically burn 300 in 25 minutes of cardio, which is replaced by a pint and a half of guinness...
