By the numbers

We had a health-themed party at work yesterday, and they gave out little Zillian-branded pedometers! So cool. I got an extra one to give to the Leaning Tower.

My body fat is, according to one of those electrical capacitance thingies, about 16%. I've been trying to bring that (and my total weight) down a bit lately... I think it's working, although my weight seems to depend a LOT on how the pooping goes. Today: not much, and I drank lots of water, and I weigh 4.5 pounds more than this morning. Weighing twice a day is really, really interesting in terms of showing how much variation there can be over a normal day/week.

Today it's raining and thunderstorming. Every instinct says it's a day to stay on the couch. Off to work.

1) That's awesome about the pedometers.

2) I have a capacitance bf measurer and it varies so much I don't use it anymore. I'm tempted to do a dunk tank.

3) My body weight definitely fluctuates according to poopage. I'm always excited to hop on the scale after a really good one. Ha, this is just going to lead you to mention my poop-talk in line at sebastian's again isn't it?

That's cool that you own one. They're more accurate than calipers, as I understand, and it's hard to have a dunk take at home, so I still sorta want one.

I will wait until we're in a classier place than Sebastian's next time. :)

On a related note (body mass, not poopage), I heard lately that we lose a non-negligible amount of mass through exhaling carbon. It makes some sense, 02 comes in and CO2 comes out so we're adding an atom to the molecule, but I haven't done any research into this. Do you know if it's true? I'm a bit fascinated by the concept, even though it has no practical application besides planning shuttle payloads.

Like any of the bf measuring devices they're affected by the testing condition consistency, so I've heard that in well-trained hands calipers can be more accurate. Honestly every time I look into it I get annoyed because there are so many conflicting reports out there. I just want the damn number. The impedance ones are really thrown off by hydration changes, I've seen .04 swings over one day, which bugs me because that's 5+lbs of lean mass difference. They're more accurate for people with lower body weight and body fat though I believe so it might be more effective for you. In fact, you're welcome to borrow mine for a couple of weeks if you like and track it's consistency. I have one of the better hand-held models.

As far as CO2, never heard that. I guess I could see it being somewhat true, I don't have any real data to share there though.

I would really love to borrow it for a while and play with it. Maybe I could borrow it on Sunday when we do the coffee? I promise to do some experiments with it, like try it, chug a bottle of water, try it again. And post the results.
