You don’t just poop out food well you actually poop out old bacteria, your intestine as you know are very long and hold quite a bit, poop will have general waste being produced from the body old cells, old bacteria all sorts. They will become less and less but the body will still produce them
Weird isn’t it 🤣 cuz u think no food no poop right?
Have done fasts that were longer then 2 weeks.
Even those you eventually poop. It’s not much, and isn’t “solid” but it happens.
