It's also the case that your metabolism is regulated based on how much food
is available, how likely you are to be eaten by a tiger, etc. I've seen
studies where people imagined being in danger and (over time) lost weight,
and the doctors doing the study figured it was because your mind was
preparing you to run away.

To optimise your muscles for speed, you need low load, repetitive,
sustained and fast exercises.
Doing the classic biscep building routine WITHOUT weight at about 50 to
60 flexions/extentions per minutes would be a nice example.
Then, whatever you do that use your muscles, will initialy burn fat.
Then, in the long term, you'll start to gain weight as you build up
muscle mass faster that you burn fat. And remember: muscle dencity is
larger than 1 (sink in water) while fat dencity is less than 1 (float in
water). That's why I don't float, I don't have enough body fat and my
muscles and bones have a somewhat above average dencity. It makes it
prety hard to learn to swim...

Seems reasonable.
Note that stress makes you ill. (I'm not talking about having a naff day
at work. I'm talking about being /really/ stressed out.) Thing is, when
humans evolved, the only reason for being "stressed" was that you're
about to be attacked by something, and you should either kill it or run
away from it, really fast. So either the threat would be killed, or
you'd escape, or you'd die. Either way, the situation would be resolved
pretty quickly.
So the stress reaction is only supposed to be used for a short time. But
today, a "threat" isn't necessarily something you can resolve in a few
minutes. It can go on and on for months. Meanwhile, your body is
prepared for imminent physical conflict 24/7. Gradually that screws
everything up.
I'm wondering whether stressing yourself to try to provoke weight loss
is actually a good idea. I suppose it depends on the degree. And hey, if
you only need to do that until you reach your target weight, maybe
that's not so bad...

Ironically, I can't swim for the opposite reason: After about 2 meters
or so, I'm too exhausted to continue.

You're doing it wrong, is all. It's really, really easy to learn how to swim
however far you want to go.

It's really super-super easy.

How to learn to swim properly:
1) Buy swimming goggles. They are *essential*. Don't bother trying without
them. (When you buy them, it's extremely important that you check that they
are watertight and don't leak water when on. They should act like suction
cups.)
2) In the pool, before starting any swimming, learn to immerse yourself
under water and exhale air from your nose at a normal breathing rate
(ie. not too fast, not too slow, just the normal rate of breathing).
Do this repeatedly over and over (iow. when above water, inhale, then go
underwater, exhale air from your nose at a normal pace, come up, repeat).
3) Look up some pros swimming using breaststrokes. (There are some
animations in wikipedia as well.) This is by far the easiest form of
swimming. Swim like that. Pace your breathing with the swimming strokes,
just like in step 2: When your head is above water, inhale, when it's
underwater, exhale from your nose. Try to maximize the time your head
is underwater and minimize the time above (no need to exaggerate, of
course).
Don't rush to other swimming styles. Breaststrokes are by far the
easiest and most economical.

In all the years that I've been alive on this Earth, I have never, ever,
even once, found a pair of goggles that don't leak like a sieve. As far
as I can tell, goggles just flat-out don't work. (Or maybe it's that
only the incredibly expensive ones work, I don't know.) Every pair of
goggles I've ever owned has been a total waste of money.
Also: People who open their eyes underwater. OUCH! >_<

You just have to search. Go to the shop and try every one of them
(as said, try them on, and if they act like suction cups and don't fall
off even without the strap, they will probably work). If you can't find
good ones in one shop, try another.

I used to speed swim - never had a problem with inexpensive goggles
leaking - but the problem that I did tend to have was that they fogged
up. Even the anti-fogging ones would give me trouble.
> Also: People who open their eyes underwater. OUCH! >_<
I'm with you on that. Especially chlorinated water. That just stings,
and I never could get used to it.

There's a lesser-known trick to help that: Before starting to swim,
spit on the inside of the goggles (and rub the spit on the inner surface).
It's not as gross as it sounds, and it helps surprisingly well. In my
experience you might still get a slight amount of fogging, but considerably
less.
(I'm assuming human spit creates a protective "layer" that stops
fogging.)
