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).
Everything from 3 times a day to once every 3 days is normal. It depends on how much you eat, how much of it your body can absorb, your fiber intake and some genetic variance too.
Your intestines aren’t a conveyor belt, things don’t constantly move. There are multiple muscles acting as a valve between different sections. Based on the factors above your body decides when to push stuff to the next section including the exit.
