It’s not so straightforward as it depends on so many things. For example, your eating window, macros, electrolytes, physical activity, etc.
I would rather do a longer dry fast every week or every other week and on the rest of the days have a normal eating and drinking routine without such restrictions.
I have a feeling it would actually be good for you, but since this is a pretty new area of science we don’t know for sure. Thing about it evolutionary wise, people wouldn’t have had access to on-demand water 24/7, so it makes sense we can do without it and function perfectly for longer periods and/or on a regular basis.
I’ve been doing dry omad since just before Christmas and apart from the odd day where it was clear I needed to drink in a bigger window I’d say 99% of the days I’ve been drinking all my fluids in a 1-2 hour window and I feel great
I feel like that’s exactly my average day on adhd meds (It stops my appetite until it wears out) so I think many people prob live like that. idk about healthy - Obvi my psychiatrist recommended I eat throughout but hey, I felt fine!
