On the water fasting side of things, there seems to be a general agreement that 50-100 calories during a fast doesn’t “break” the fast.
Is there a similar amount of water that would hold true for a dry fast? like 1-2 oz. of water?
Idk what the technical thing would be. On my first 5 day DF, at day 4 I was in the sun and pushing a little too hard and almost passed out. Would always carry a hydroflask with cold high ph alkaline water with electrolytes for emergencies. So I allowed myself too small gulps of that water, then drenched my shirt and put it on. Then continued the DF and didn’t take another sip till the end. I’d say you’re fine to take it if you absolutely can’t do without it, and then go right back into dry fasting. Now if you do this continually or for too much, it’ll send signals to your body that you’re receiving water (so it stops producing its own metabolic water for a bit) and you’ll have to waste a couple hours getting back to that depleted state. So yes you can have some but keep in mind it knocks ya back a day or a bit less I think if it too much.
I don’t think there is general agreement that 50-100 calories doesn’t break a fast. I think that some people think that it is better to have the small amount of calories if it allows you to go ahead and fast for longer. Also it can depend a lot on what your goals are, if it is to just be in ketosis and lose weight, then 50-100 calories of fat won’t detract from that goal. But there really isn’t a controversy here, 50-100 calories does break a fast.
So I’ve heard people say they do rinse their mouth and maybe take a tiny bit of water, I’ve heard people call it a damp fast, which is clearly not a dry fast.
So the real question is, will it be OK if it helps, you dry fast for longer? For some people that water in the mouth brings some immediate relief. However I have read that it might actually make it more difficult to dry fast for the long run. It messes up the systems that will get your body producing its own water. However you’re probably still getting a lot of benefits of dry fasting.
