How does it work that we eat few times a day, but usually we poop only once?

Is the colon somehow programmed to buffer the waste until the time is up and then dumps it all further?

Got this thought when observing my dog who eats twice a day (morning and evening) and more or less poops twice a day (morning and evening).

Cuz we're generally more full of shit than we like to admit.

[-] MTK@lemmy.world 15 points 5 days ago

Science time!

Fast for 24 hours then use an anal douche. This should completely clear your digestive track.

Now eat for the next 24 hours while measuring everything you eat. Every time you poop make sure to measure it, either my measuring the poop directly (poop in a bowl?) Or by measuring the difference in weight after you poop (be sure to first pee as to not measure liquids)

Now fast for another 24 hours while continuing to measure your poop. By the end of it you should have to total weight you eat and the total weight you pooped. For most foods you can probably reduce the weight by half to account for liquids (most will be pee, some will be in your poop, this will depend on the liquidness of your poop)

Now you will probably notice a few things:

  1. you poop a lot less mass than you consume, this is because you turn a lot of it into energy.

  2. there is a lot of water in food

  3. you probably poop more than you think (one dump can be quite big in comparison to a meal when removing liquids)

Enjoy!

OK, but I'm using your bowl.

[-] untorquer@lemmy.world 2 points 5 days ago

You could also just measure without fasting over a full week and compare averages. Assuming your diet is consistent.

I'm planning to use mine on my 40th birthday. It should make for a really special day.

[-] victorz@lemmy.world 5 points 6 days ago

Imagine the dump saved up for 40 years. The relief. Hnnng.

[-] ivanafterall@lemmy.world 7 points 6 days ago* (last edited 6 days ago)

But first the pain of delivery.

[-] victorz@lemmy.world 4 points 6 days ago

Oh... God...

In fairly certain there are days I lose track of many shits I took.

some people poop 3 times daily, others 3 times a week, both are considered normal.

[-] Dasus@lemmy.world 37 points 6 days ago

I don't usually eat more than once or maybe twice a day but often still take more than one shit.

Everyone's bowels are bitty different.

[-] Nemo@slrpnk.net 36 points 1 week ago

Yes, your colon is a poop buffer.

[-] rekabis@lemmy.ca 20 points 6 days ago

The rectum is considerably larger than your mouth, and can hold a lot more shit.

[-] TomAwsm@lemmy.world 8 points 6 days ago

You only eat a mouthful per meal?

[-] Atemu@lemmy.ml 10 points 5 days ago

I generally prefer to not get shit in my mouth at all but you do you.

[-] tiredofsametab@fedia.io 19 points 6 days ago

I'm 2-3 times a day. it was 5+ until we figured out my body hates gluten

[-] Routhinator@startrek.website 7 points 6 days ago

Unless you are celiac, its likely FODMAPs your body hates. There is a correllation between the amount of gluten and FODMAPs in food that makes watching gluten get part of the picture, but you're missing the whole picture and thus likely not completely regular yet. FODMAPs are in most things. Onions are concentrated FODMAPs and so is tomato sauce.

My doc gave me this initially https://www.ibsdiets.org/fodmap-diet/fodmap-diet-chart/ but there are others you should cross reference for more food item coverage.

I have to admit. Onions, garlic and mushrooms were haaaaard to remove. Ive turned to Miso and a lot of japanese and thai food with the onions removed from any recipes to get this right.

But now I'm down from 5 poops to 1 poop a day.

[-] paige@lemmy.ca 2 points 5 days ago

I’m about to try this diet to get to the bottom of it, but I think onions/garlic seem to be a problem. It’s not that bad a condition, but I’d like to at least be able to know when I’m signing up for indigestion.

[-] Corkyskog@sh.itjust.works 3 points 5 days ago* (last edited 5 days ago)

Additionally "FODMAP" is a huge umbrella.

Most people don't have issues with every type in that umbrella. A full FODMAP diet is usually too restrictive for people to get the most out of their diet, and isn't recommended for most. Ideally you go full FODMAP for a month, then start reintroducing foods until you know which kinds bother you.

Sometimes it can be as simple as eliminating sugar alcohols for the lucky.

I'd be more miserable without that food than I am with gastro issues. Fuck that.

How much you poop is going to vary based both on your body and your diet. Ive read anywhere from 3 times a day to once every 3 days can be normal.

[-] potentiallynotfelix@lemmy.fish 7 points 6 days ago

3 times a day is normal? that sounds torturous!

[-] bitchkat@lemmy.world 7 points 6 days ago

Pooping is one of life's simple pleasures.

Well, Dr Goldstein clearly doesn't own a smartphone...

[-] nondescripthandle@lemmy.dbzer0.com 6 points 6 days ago* (last edited 6 days ago)

Id agree. Swapped all my carbs to higher fiber carbs a bit ago and I'm still upset when I have to shit twice a day, I could be happily wasting that time instead of having to shit again.

no poop knife for this guy, amiright?!

I would guess (without knowing for sure) that it's because your body absorbs a part of the food, so you poop out less mass than you eat.
