I've been dry fasting for many years now, going over 100 hrs dry more times than I can count now. It helps get the body "fat adapted" to go on a "fasting mimicking diet" for a few days on either side of going dry. Myself, I'm going thru that process at the moment, on day 3 of nothing but liquid fats for fuel, i.e. bulletproof coffee in the mornings, bone broth in the afternoons, and a non-caffeinated Dandy-Blend hot drink with some coconut oil added in the evenings.

Tonight at midnight, after properly hydrating and mineralizing with plenty of water, baking soda, and some fresh squeezed lemon juice, I'll stop all fluid intake at midnight. Consuming nothing but air over the next few days at least, it gets easier when I wake up the 2nd day, about 32 hrs dry, as I generally feel great and have no desire to consume anything at all. After 3-5 days, depending on my activity level and local temps, I'll start back on the liquid fats diet for a few more days.

Going "dry" lowers all inflamation throughout the body, resets and boosts the immune system, and eliminates many of the fats that may have been storing toxins. Breaking down bodyfat for water provides the highest quality "living water" we can find anywhere and regularly using the ketone energy pathway helps make me "metabolically flexible". My relationship with food/hunger and water/thirst have changed drastically, as my Will now rules over my Body, rather than the other way around as for most of the human population. The impacts on my personal discipline, immune system, and overall health have made this a lifetime practice that needs no outside sources to validate the benefits of to my health.

This does tend to have an impact socially, though, as so much of socializing revolves around food and drink and we tend to not notice until we stop altogether.

Good luck. Fear not, trust your ability to listen to your body, we are not nearly as fragile as we're made out to be. Unless you're under 10% bodyfat, there's little risk of dying after 3 days with no water as we're taught. Muscle cramps and potentially kidney stones are the main risks and proper preparation and discipline manage those easily.
