Do you intentionally try to drink x cups of water per day?

That's interesting. I always thought that neurons were the most energy hungry.

It's a pain to drink that much water daily, I definitely wouldn't do it if I didn't have to.

That's what I used to think but, but nature has energetically prioritized clearing nitrogen wastes. How great would our civilizations be without a sewage system?

the human kidneys constitute only 0.5%of body mass, they consume 10%of the oxygen used in cellular respiration

While the brain represents just 2% of a person's total body weight, it accounts for 20% of the body's energy use

Though if you look at this paper

https://www.ncbi.nlm.nih.gov/pmc/art...0and%20tissues.

Ranking of energy by density is 1. Heart. 2. Kidney. 3. Brain. 4. Liver

Ranking of total energy usage by organ 1. Liver. 2. Brain. 3. Heart 4. Kidney.

I think most people wouldn't guess that the by organ, liver uses the most energy.

It takes energy and Na for the kidney to clear free water, but if that's what you have to do to not have stones, then you gotta do what you gotta do. BTW, my understanding is that nephrons require more energy than any other cell even beyond neurons and hepatocytes. That's why CKD is prevalent when your bioenergetics becomes dysfuctional(ie. IR and DM). If you kidney energy demands aren't met, well it starts to fail.

A nephron isn’t a cell.

I have the "eating disorder" where I when I work I only eat and drink(2-4 cups of water/tea/etoh) during dinner, nothing for the rest of my day. Been doing this for almost 4 years. 3-4/wk. While I work I still urinate throughout the day. It's not voluminous, maybe 3-400cc. Mouth is never dry, I go outside to spit throughout the day. The urine is a light yellow. Never dark. I can always see the toilet bowl stains through the urine, even after housekeeping has cleaned it. When I first started doing this, my UA had ketones, but those are gone as of 2 years ago. I think I have renal resorption of ketones as to not waste energy.

Huh?

Huh?

Don't MD's always document "moist mucous membranes" as code for not being dehydrated? Also, mitigates sialolithiasis. And if one isn't drinking, the H in the spit H20 is coming from fatty acid metabolism. The O is coming from air.
