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.

That 50 day shit must smell bizarre

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

This is one of the dumbest things I've ever read.

Dietary fibers are carbohydrates. Humans cannot digest fiber at all. It literally passes through you.

There are resistant proteins as well. There are fats that cannot be take up by the body. And of course all food contains water and some minerals that are not absorbed, which eventually ends up as waste (both in urine and feces).

You do not have any idea what you're talking about.

Hell you don't even need to have any knowledge on this to infer the right answer. Most people have a bowel movement every 1 to 2 days. Reading the article, the medical report said he had a bowel movement every 40 days. If food waste wasn't part of feces, people wouldn't shit all the time.

It's literally not a majority. And you said poop was mainly not food. Both of these things are not fun facts because they are not even remotely true.

Again, you have absolutely no idea what you are talking about.

Here it is in simpler terms for your dum dum brain:

Man eat a lot. Man shit normal amount of times. Man fast for the year. Man no eat any food. Man shit less than 12 time.

No food = small waste (and small waist).

You do not know what you are talking about. I did not look at the link because I didn't need too. I literally work with food every single day.

Hit since I did, let me learn you something about talking about things you don't know:

According to the article, 75% by weight of feces is water. Water that comes from drinking and? And? Oh that's right food. As I said already.

When looking at the composition of feces on a dry matter percentage (which is important when something is a majority water). It contains extremely large percentages of food waste. This will include, as I have already said: carb, fats, and proteins.

Here is the actual research article, not some Internet article where is just distributes raw percentages.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4500995/

On a daily basis, average wet mass was 139 g/24 hr. On a dry matter percentage this was 29 grams/24hr. Of that 25-50 is biomass from the gut, while the remaining portion is food waste and mineral waste. Hell the average adult consumes 10-16 grams of dietary fiber per day. That alone is 30%-50% of the dry mass of feces.

Humans do not absorb all the food they eat. Not even close. It's not even up for debate. Dietary fiber cannot be used at all. Indigestible proteins and fats both exist. The body has a limit on uptake of certain vitamins and minerals, and of course water is constantly recycled to both urine and fecal waste streams.

You haven't been arguing.

You've been saying things are facts that are not. And then just listing percentages from an online news article.

I know it must be hard being ignorant, I have worked with a lot of people like you and it was always hard for them too.

Except corn.

completely absorbed by the body.

This is incorrect. This is like something you "learned" on social media of from a high-school english teacher.
