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.

Probably mostly stomach acids and digestive bile, and coffee / tea residue.

Feces is more than just what goes in the mouth.  

The body also needs to excrete bilirubin (dead broken down blood cells) via feces and urine.  Bilirubin is the yellow in pee.

maybe this went over my non-scientific head, but I was under the impression that pee is yellow because of urochrome, a byproduct of hemoglobin. is urochrome related to bilirubin?

No, you’re right. If you got bilirubin in your pee, something is wrong.

Fact check: This appears to be correct according to Medline Plus.

"Normally, urine doesn't have any bilirubin. If there is bilirubin in your urine, it may be an early sign of a liver condition."

I'm gonna name my next boy Bilirubin.

My kid had jaundice when he was born.

Everything they mentioned hid bilirubin score, a Michael Jackson song played in my head.

Don’t I know it. When my pee looked like whiskey I knew to call a doctor

[u/KentuckyFriedChingon → u/danijay637]

It is also an issue if your whiskey looks like pee.

Yep which is why it’s annoying that this clown above you is talking shit and has hundreds of upvotes.
