How much does poop weigh?

Frankly, I'm surprised that this question has not been definitively answered by Cecil yet as it seems vitally important to humankind.

After lunch today I sat down on the toilet and unleashed a big ol' poo, pardon my grossness

So then I got to wondering if this might have affected my morning weigh-in, which was higher than expected.

Searching on the Internet did not seem to be very fruitful. 2 sites I found:

http://seattletimes.nwsource.com/htm...ortrait29.html
Average daily weight of human poop: 2.5 pounds

http://www.susangoodmanbooks.com/edu...poopguide.html
Each day, on average, people produce 1 ounce of poop for each 12 pounds of their body weight

(which would be closer to 1 lb)

Now I realize that poop weight is extremely variable, so I'm just looking for a range, but 1-2.5 lbs seems like an awful big range, especially considering that 2.5 is supposed to be an "average"

Any thoughts / wisdom / insight?

I suspect that on average it's a little denser than water (1 kg/dm3). I base this on the fact that itusually sinks. So, if we know the volume typically ejected in one session, we'll know how much it masses.

I'm sorry, but I'm not willing to do an experiment to answer this question.

I'm 5'8'' and weigh 163 lbs.

After my morning BM, I weigh 161.5- 162 lbs.

I take Metamucil every night at 9:30, or after heavy meals.

You want info, I give info. And hope it is useful.

What we need is a few people who are regular and have a very accurate scale in their bathroom of choice.
1. Weigh yourself before your BM and then again after your BM.
2. Plot results over a set length of time.
3. Compare results.
4. Profit?

Well, I can tell you that on even an innaccurate scale, one does weigh noticably less given a substantial deposit (don't ask how I know this.) Now one needs a way to measure volume.

Several years back we had a pretty accurate "spirit level" scale in our bathroom, and my wife and I regularly weighed ourselves before and after. As I recall, it took a pretty impressive dump to exceed 1#, and I don't think either of us ever attained a 2-pounder. Obviously, YMMV.

Sorry. If you want anything like an accurate weighing, the container has to weigh less than what you're weighing.

But I suspect there are medical tables out there for this sort of thing. Hospitals sometimes check on output.

I am having a hard time believing that just the US dogs produce almost as much poop as all humans on Earth.

They don't - read that more closely - the people figure is per day - the dog figure is per year.

Word.

You've also got to take in to account the weight of the the #1, if you normally hit the Exacta.

We've got a digital scale that's accurate to a fifth of a pound. Being a guy, I've often used it to check the weight of my daily constitutional.

My normal output is in the 1-1.2 lb range. I'm a 150lb male who eats like a horse and probably drinks too much coffee.

If for some reason I've held it for a day, I get in the 1.4-1.8 lb range. The non-linear distribution is probably due to my large intestine doing its job and making jerky, so to speak.

My most impressive achievement to date is 2.2 pounds, after a three day camping trip where I didn't go for nearly four days.

I had to look into this….

From http://snunes.blogspot.com/2004_08_01_archive.html
Quote:
the band was using five different tour buses in Chicago at that time and we provided the license plate numbers of all of them, we provided photographs of any of the buses they requested and we offered to supply DNA evidence to determine if one of our buses was the bus involved.
I‘m at a loss for words…

No shit! Er, uh I mean...

Even if the Dave Matthews entourage crapped like a pack of barnyard ungulates, one suspects the band bus waste tank did not actually contain 800 lb of pure dookie. More likely the contents were composed of...shall we say...exacta.

I wasn’t questioning the weight of the poop. I was wondering exactly how they went about testing a busses DNA.

You laugh - but on Channel 4 last night during some real-life medical dreck (Embarrassing Medical Conditions) the doctor host collected stool samples from a bunch of students to determine their bowel condition. They were all sitting around a table with translucent tupperware containers while he comments on their crap - he even uses one container as a rattle to demonstrate a lack of fibre in the student diet.

I know that Channel 4 is mostly shite, but I thought that this went a bit far. Then again, this is a show that has shown penile pimples in-situ on a previous show, so what can you say...

One of my great joys in life is trying to best my personal heftiest poop (I know, I know). This is going to get gross quickly, and I recommend hiding the children.

I have gone to great lengths to try and increase the mass of my excretion. Iron and fiber are crucial, as they both serve to increase the density of the drop. Cheese is also good, as it has the notable effect of binding one's bowels up, thereby allowing one to (pardon the phrase) stuff ten pounds of crap in a five-pound bag. The simplest course of action is also the most important: eat a lot and hold it in. This does result in a methodological flaw in my personal studies, however. Since the deuce is, at the time of the blow, so anxious to be free, it's really rather impossible to take the time to urinate, weigh, and then defecate. As a result, I'm forced to weigh myself (very uncomfortably, but oh man there's a good feeling coming) and then hit the pot. My personal record (remember, combined urine and fecal matter, having gone to great lengths to increase the total weight by specific eating habits and by drinking a load of Coke Zero -- the caffeine acts as a diuretic and the liquid itself fills up the ol' bladder) is, if I do say so myself, a rather impressive eight pounds. IANAD, but I'm sure that can't be healthy. I haven't tried this for a while, but if science calls...

My favorite is "major transaction." Chick McGee has used it. Not sure if it originated with him, though.

While I don't have a scientific measurement to provide, I can safely say that it's the only time I've ever stood up, turned around, and frozen in slack-jawed awe.

Why, why, why would you open your mouth in front of such a thing?! The smell wasn't enough for you? Did you need to have all 5 senses involved?
