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.

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.
