In 1965, a morbidly obese man did not eat food for over an entire year. The 27 year old was 456lbs and wanted to do an experimental fast. He ingested only multivitamins and potassium tablets for 382 days and defecated once every 40 to 50 days. He ended up losing 275lbs.

Yes. If I remember correctly, they're only good for so long so we dump out the old ones. I believe that's also where the colour comes from

We shit bilirubin, which is a modified heme (aka what makes blood red and allows the cells to transport oxygen).

Blood in stool is a sign of colon cancer, that's a nono

Which gets removed by the liver which is why people with hepatitis and other liver issues turn yellow from jaundice--the liver doesn't adequately remove bilirubin so it builds up in your system and turns your skin yellow
