Fun thing #1: When people say "only fifty calories", apparently they
/actually/ mean 50 kcal - i.e., 50,000 calories. This weirds me out
slightly.
Anyway, at the end of last year, I joined a gym. I didn't actually visit
very much, to be honest. But now I've signed my dad up too, and for the
last two weeks we've been going to the gym together almost every night.
Because, let's face it, we both need the calorie burn!
It would be nice to walk around with an impressive set of bulging
muscles. But obviously that's impossible. (I mean, unless you quit your
job and become a full-time body-builder - and how has the money to do that?)
More importantly, I love to dance, and it frustrates the living hell out
of me that I can only dance for about 45 seconds before I'm so utterly
dead that I can barely stand up any more. That being the case, stamina
is something I want to work on.
The gym has all manner of machines you can play with. I did try using
the cross-trainer. But it forces you to take unnaturally large steps,
which make my legs really hurt. More recently I've been hitting the
treadmill.
Dancing is complicated. It takes a lot of mental focus to do it right.
You can't dance when you're too tired to think straight. But running is
simple. You just need to keep putting one foot in front of the other.
And there are no peaks and troughs to it. You just switch the machine on
and start running.
There's a lot of psychology to exercise. If you get on the treadmill and
start running, it's all too easy to just /stop/ when you start getting
tired. So what I do is program the machine for a specific duration at a
particular speed. That way I can watch the timer ticking down, I have a
goal to aim for, and I can't move the goalposts if I get bored or tired.
Right now I have a cold. But for the last few days, I've been running 1
mile every night. That's 10 minutes of running at 6 MPH. Sounds easy,
right? Well let me tell you, by the end of those 10 minutes - no, wait,
*before* the end of those 10 minutes, I am absurdly exhausted. One night
I made the mistake of running a mile, and then an hour later trying to
do a second one. That nearly killed me.
Fun thing #2: I used to think you could eat whatever you like and then
go down the gym and just burn it all off. But that, apparently, is quite
impossible.
The treadmill (and several other machines) attempts to estimate the
number of calories you've expended. It seems to do this based solely on
the selected speed and whatever you lied to it about your weight. (I
would expect the /real/ energy usage to vary wildly based on a huge
range of other parameters...)
According to this machine, my flabby 180 lbs pounding the treadmill at 6
MPH burns about 15 kcal per minute. So a 1 mile run burns off a 150 kcal.
So far so good.
Now look at that bottle of coke in my hand. "47 kcal", it says. So just
by having a drink when I'm done, I've completely negated 30% of that
mile. No, wait a sec - that's 47 kcal per 100 ml! But this isn't a 100
ml bottle - it's 550 ml. So that's... uh... 258 kcal! o_O Yes, this
small bottle of sugar-water contains /drastically/ more calories than
what I just half-killed myself burning off. (And trust me, after that I
*need* a drink!)
150 kcal sounds like a lot - 150 is a big number. But when you realise
the calorific value of some common everyday foods, you discover that
this is peanuts. (Incidentally, peanuts have a lot of calories.)
For example, if I eat a 500g bar of chocolate, that's 1,000 kcal. Then
again, that's a pretty big bar, so maybe it's not so surprising.
Sucrose is apparently 400 kcal per 100g. Butter (depending on which
brand) is something like 600 kcal per 100g. Of course, nobody sits down
and eats 100g of either of those things. But how about the bag of rice I
had with my supper? Apparently that's 300 kcal - and that's just *rice*!
People tell you that stuff is healthy.
Fun thing #3: For reasons beyond my comprehension, the rice gives me a
figure per 100g, and also per "serving". Apparently the idea is that
you're supposed to microwave this individually-packed rice and then eat
only half of it. WTF?
Similarly, I pick up a 36g packet of crisps and it tells me the
nutritional values "per 12g serving". Serously? Who THE HELL buys an
entire bag of crisps, opens it, and then eats only one third of it? I
mean, if we were talking about one of those big over-sized packets then
sure. But the little hand-sized ones? I've seen plenty of people buy two
and eat them both. There's hardly anything in them, after all.
It seems crystal clear to be that the /only/ reason the manufacturers
would possibly do this is so that they can print smaller, less
frightening numbers on the packet. Nobody eats a third of a packet of
crisps; that's, like, 4 individual flakes!
Perhaps my next project should be to sit down and compute the calorific
value of those lemon cakes I keep making. (I doubt the value changes
significantly due to cooking...)
Fun thing #4: Apparently I can lift 100kg with my legs. Notice that *I*
weigh less than 100kg. Weird, eh?
I can also left 45kg with my arms. It's taken me a while to work up to
that. I doubt I can lift any more than that, not because my arms won't
do it, but because my wrists can't take the load...

Some randomly-selected food items, sorted by calorific value per 100g:
126 kcal White rice.
147 kcal Eggs. (~70 kcal per egg.)
256 kcal Blackcurrant jam.
263 kcal Minced beef.
302 kcal Lemon curd.
313 kcal Brown self-raising flour.
335 kcal White self-raising flour.
400 kcal Sugar (doesn't appear to matter which kind).
410 kcal Cheddar cheese.
410 kcal Flora margarine.
680 kcal Stork solid butter.
I also managed to find out that the milk we buy is 207 kcal / 100ml.
Now, if I know how many ml there is in 100g...
Anyway, based on the above data, we can compute the total calorific
value of one of my lemon cakes:
250g flour = 837.5 kcal
250g sugar = 1,000.0 kcal
250g butter = 1,700.0 kcal
3 eggs = 210.0 kcal
3,747.5 kcal for the cake mix
1 jar of lemon curd is 400g, so half a jar is 200g.
200g lemon curd = 604.0 kcal
400g icing sugar = 1,600.0 kcal
5,951.5 kcal final total
If each person eats a 1/12th slice, that's 496 kcal per slice.
Now compute how many months you would have to run non-stop to burn that
many calories. Yeah, exactly.

I believe I may have miscomputed here.
The layer of buttercream in the middle is 100g butter and 200g icing
sugar. It probably takes another 200g icing sugar to do the top. So that
gives us
200g lemon curd = 604.0 kcal
400g icing sugar = 1,600.0 kcal
100g butter = 680.0 kcal
6,641.5 kcal for the whole cake
553.5 kcal per slice

In a similar vein of questionable advertising/labeling:

Rule #1 - Never say anything that isn't true, but.. never actually say
what **IS** true either.

I think we have had this conversation before, and back then you didn't
seem to believe me (or want to believe me, or whatever.)
If you want to get in good shape and gain stamina, so that you can dance
for more than 45 seconds, what you need is about 1 hour of aerobic exercise
5 or 6 times a week.
If you are in horrible shape, you achieve this by walking every day about
7 to 10 km at a good pace in one go (you have to end up sweating). You need
good shoes for this.
After 3 to 6 months you might be able to start jogging, and that's the
perfect continuation to this regime.

Go slower and further - once you have built up to 3 or 4 miles at a
slower pace you'll find if you go back to 1 mile you can do it a lot
faster without much effort. Get a heart rate monitor watch that beeps
above a certain limit, it helps to control your speed and stop you
getting worn out too quickly.

But when compared to what your body burns off anyway during the day
without any exercise (around 2500 kcal) running 1 mile doesn't really
allow you to eat significantly more than if you didn't run.

That's why there's a million diet options available - the 600 ml bottle
of pepsi max here on my desk has 100x less calories :-)

That reasoning doesn't explain then why they put the values per 250 ml
serving on the front of drinks, when they could put the values per 100
ml instead. I wonder if there is a set of "standard" serving sizes?

Yes, nobody in the world ever built muscles without being a full-time
bodybuilder. m-/
(I have a former boss who was a distance runner - he had something like
5% body fat, ran marathons, but it wasn't his full time job.)
What have we said before about these absolutist declarations that
something must *obviously* be impossible except/unless one makes the goal
the only thing in their life?
Oh, yeah - that that's usually entirely false.

I have a crazy guy who sits next to me in our office (so again training
is not his full time job). He's going to run the London marathon this
year, but for him that is just a warm up for the iron man triathlon he's
doing later in the year. In case you don't know (I didn't until I looked
it up) it's 2.4 miles swimming, 112 miles cycling and then a full
marathon running. That probably will burn a few days worth of calories :-)

My spinning coach is going to try to run 30 ironmans (ironmen?) in 30
days, next fall. In 2008 he completed 10 ironmen in 11days 6 hrs and
last oct, he did 5 in 73 hours 40mins. He's currently the 2nd
utlratriathlete in the world.
http://www.iutasport.com/?page=worldcup
And that's on top of his full time job in a hospital and his part time
job as a spinning and running coach.
But of course, that's impossible.
