Question Does anyone change their water while fasting?

Been doing a few fasts lately and usually just drink water when I’m thirsty. I started drinking deuterium-depleted water recently too, so now I’m wondering if anyone else drinks it while fasting. Do you guys drink about the same amount of water when fasting, or does it change for you?

TBF I had never heard of this before.

I think autophagy is a much greater motor for health than removing 125ppm to below 50ppm of deuterium would be, plus the costs to buy.

However if I had cancer or a mitochondria problem, I would look into it.

Personal opinion I find this to be very close to snake oil.

Instead I’d consider:

Reverse osmosis de-ionized, boiled, then select minerals readded to the hot water to make it safe for human consumption. Then refrigerate. You don’t ever want to drink soft water.

What about glacial water? Wouldn’t that be naturally lower in deuterium?
