This thread has given you a few you can use it as a starting place and Google it to do your own research. I have spent hundreds of hours of research on keto and fasting so that I can understand the studies and research and how it applies and can extrapolate one to another. Its clear you don’t trust the research of others so you should do your own research.
Google ‘dry medical fasting’
See, the title of this thread is “Dry Fasting. Is there any science to this?” You are claiming there is. Is it truly impossible for you to provide even one link to a scientific study? I’m going to conclude, after having asked you directly three times, that it is impossible and you have no solid evidence to back up your claim.
LOL There are both videos and links to several sources of studies and research on this thread all it takes is a click and some reading 
Youtube videos and a link to an article on a site called “Interstellar Blends” lol. Guess what, I watched the video & read the Interstellar site. It had 2 links to studies on dry fasts, neither of which showed ANYTHING about the effectiveness of dry fasts compared to water fasts.
And to be clear, of those 2 studies, one was on mice and petri dishes. and the other was on “water deprivation” meaning a restricted water intake, not a dry fast.
The studies in question (and please note the direct linking to facilitate a discussion, instead of begging people to google it lol)
First study on water restriction:
https://www.karger.com/Article/Abstract/357718
Conclusion: The intervention of 5 FWD days in 10 healthy adults was found to be safe, decreased weight and all measured circumferences, and improved renal function considerably.”
FWD is food & water restriction, not dry fasting. And the conclusion doesn’t say anything about effectiveness compared to water fasting. And it’s just 10 people.

The present study explored the possibility that dehydration influences Klotho expression. Klotho transcript levels were determined by RT-PCR, and Klotho protein abundance was detected by Western blotting in renal tissue from hydrated and 36-h-dehydrated mice as well as in human embryonic kidney (HEK293) cells. Dehydration was followed by a significant decline of renal Klotho transcript levels and protein abundance, accompanied by an increase in plasma osmolarity as well as plasma ADH, aldosterone, and 1,25(OH)2D3 levels. Antidiuretic hormone (ADH; 50 nM) and aldosterone (1 μM) significantly decreased Klotho transcription and protein expression in HEK293 cells. In conclusion, the present observations disclose a powerful effect of dehydration on Klotho expression, an effect at least partially mediated by enhanced release of ADH and aldosterone.
Interesting, but again not relevant to human dry fasting compared to water fasting.
Most of our theorys come from animal studies
Did you read the research and studies on dry fasting and then compare them to water
Did you research the doctors and clinics that perform medical and therapeutic dry fasting
Keto has little research and its efficacy has to be extrapolated from similar studies and research.
Keto has a ton of research, which I am more than happy to link if you like. I found 1 study on dry fasting in mice lookng at downregulation of klotho expression. How is that supposed to be compared to anything?
I’m not begging I’m asking you to do your own research for your own bennift
I don’t have to prove anything to you or anybody my n=1 and my research is all I need 
I was trying to help you but you repay my kindness with rudeness and insult 
My bad for caring and sharing 
I’m sorry you found this discussion insulting. I feel that you have dodged the question. You said there was science. I said “show me the science”. You said “go google it for yourself”. I did, although that is beyond the call of duty as normally the burden of proof is on the person who makes the claim, and showed that the science you claimed was linked is not relevant.
Ball’s in your court. If you make a claim and can’t back it up, and feel it is rude of me to point out this out, I’m sorry.
I did but you ignored it because it did not fit your standards which is your right.
As I said the science for dry fasting (animal, metobolic,starvation, water deprivation, other fasting) is similar to that of Keto (animal, metobolic, low carb) in that most of the science is in similar studies and research and its efficacy has to be extrapolated along with current pratice
You didn’t link a single study, Dan.
There’s lots of studies of keto, and of intermittent fasting. Randomized controlled trials in humans, even.

@Jennifer_Kleiman and @Dan_Dan, I’m loving this discussion, just remember we’re all on the same team. According to most doctors we’re all nuts. 
If we weren’t open to challenging commonly held ideas, none of us would be here.
I still question the benefits and validity of a dry fast, but a couple years ago I would have said the same thing about a water fast, and now that’s something I do regularly.
The absence of evidence is not the evidence of absence. But I think we must agree that there is an absence of evidence.
‘A Comprehensive List of Low Carb Research’
Thank you for proving my point the majority are low/moderate carb high protien research and only a few are ketogenic so most of the science has to be extrapolated
I did several videos and links with sources you choose to ignore them because they don’t fit your standards and thats your right
I am happy and confident in my research and n=1

WHY NO WATER?
The ketogenic diet (KD) is traditionally introduced with an initial period of fasting and fluid restriction. *Since the 1930s it has been known that fluid restricted fasting accelerates ketosis which in turn has positive effects on preventing epilepsy.

There is a mechanistic theory behind fasting humans needing less water.
Firstly we make a little water when we respire, water and C02. fat-oxidation (eg during fasting) generates more metabolic water, than mixed-fuel oxidation.
If you are a zebra finch you can make 6x the water when fasting.
Secondly when fasting we spare protein by not only reducing the rate we use it, but we also scavenging nitrogen from urea to make new amino acids (denovosynthesis). So with fewer waste products, we need less water to make urine.
This was elucidated in George Cahills starvation in man
The fact that we may be able to get by with less water when fasting has, I suspect, been conflated with taking in less water increasing some specific benefit of the fast.
I’ve not seen any studies to support that.
BTW: Before going keto I had already seen hundreds of papers on ketogenic diets, and there may have even been almost 100 in the 4 years since.
There is a medical doctor in Russia who leads cancer patients through dry fasting; here is a .pdf of his book (badly translated, apologies: https://spiritsciencecentral.com/wp-content/uploads/2017/07/Dr.-Filonov-Dry-Fasting-Translated.pdf
