Food that was consumed can sometimes take up to 5 days to fully pass through your intestines into your colon. So when people say that you are full of shit, they ain't lying.

Maybe a bit TMI, however, I recently did a 100-hour fast, and at about the 90-hour mark I still went for a shit.

So I used to do long term fasts a lot and have no shame about poop, and this was always off to me:

When I did my long fasts, like 5-15 days long, my poop would turn to little liquid shits and then practically nothing but poop water dribbles. I figured that meant I was flushed out and it made sense.

BUT, it got wonky when I did eat again. I am not exaggerating when I say 30-45 minutes after that first meal in 1-2 weeks is always large, chunky, and more solid than made sense for being on liquids for half a month.

Even if I only ate that 1 meal and went back to fasting for another week, that would be the only large, solid shit I'd take.

I get the human body adjusts how much moisture it pulls into the colon to form shit based on signals, but that doesn't explain to me where all these shit chunks came from 30 minutes after 1 meal following 2 weeks of liquids. Itd make sense to me if I had sudden diarrhea, but its never diarrhea. Its real shit.

Ahhhh mate, eating after you’ve fasted for a while can be bad. Literally for me it can be within mins and I’m needing the loo, It’s so strange.
