I do 72 hour fasts periodically, 3 or 4 times a year. I feel they are beneficial and help “reset” things from an eating standpoint. These fasts are typically preceded by a period of gluttony (holidays, vacations, business trips)
I do drink a cup of black coffee each morning when I fast [Reply]

Yeah, I'm no doctor and haven't read up on water fasting in particular, but my first thought would be that you better be exercising as well as at least replacing the water you're losing from food.
From what I've read on simple dieting, after water weight comes muscle mass if you're not working out... I can easily lose 10+ pounds of water weight alone after a week or three of holiday-type of gorging and a few days on keto (and I'm not overweight, besides a little skinny-fatness), which is of course the same reason people come back to these types of things. And then on top of that, there's probably muscle loss and then maybe some fat.
Your liver and kidneys can take care of the "toxins". [Reply]

This is a fallacy of losing muscle mass. Once in ketosis, your body only burns stored fat.
You never want to keep exercising on a water fast as your body will crave fuel and there is none.

Walking or hiking are fine but no gym!
Your body requires protein for several metabolic processes. If you're not taking in protein, you're still burning protein. If you're reaching ketosis by eating literally nothing, your body will absolutely break down muscle to get protein. [Reply]

Again, I'm no doctor, but that really doesn't seem to make sense and there are studies that state otherwise.
Ketosis obviously works from a fat burning perspective because you're not giving yourself enough carbs to live off, but there's no magic of ketones that I've ever read that protects muscle mass by itself.
Even on a normal keto diet, everything I've read/listened to (and backed up by studies as much as possible) says to make sure you're eating enough protein and working out, and there's a ton of stuff out there on muscle loss on a high fat/high protein diet, much less no protein at all.
And the older people get, I would think it becomes even smarter to consult doctors about it and do research, as people will generally lose muscle mass as they age regardless of diet.
And for a week a year... probably not a big deal. Just pointing out that the perceived benefits of this seem to either not exist at all ("toxins") or are masked by something else (water weight and muscle loss).

Yet the folks on keto did lose more leg muscle.
