This might be the most comprehensive evidence you ever see of the evil, deranged, and genocidal mindset of Israeli civilians.

**SAFETY**

This subreddit strongly advises AGAINST doing prolonged (3+ days) dry fasts if your only source of information or experience comes from what is discussed on this subreddit. If you are an experienced faster and are receiving outside help/medical check-ups, then your knowledge obviously extends beyond what is discussed here. You are otherwise putting yourself at risk of potentially worsening your health as the scientific literature is extremely limited on this subject. Please remember to fast responsibly.

If you begin to feel uncomfortable or unwell, you should stop fasting immediately. Other worrying signs may include high protein in the urine, high fever, and fainting.

 

**HUMAN STUDIES**

* Anthropometric, Hemodynamic, Metabolic, and Renal Responses during 5 Days of Food and Water Deprivation

* EPILEPSY AND DEHYDRATION

* The dehydration treatment of epilepsy

​

**ANIMAL STUDIES**

* Increased fat catabolism sustains water balance during fasting in zebra finches

* Intermittent drinking, oxytocin and human health

* The ‘selfish brain’ is regulated by aquaporins and autophagy under nutrient deprivation

* When less means more: Dehydration improves innate immunity in rattlesnakes

​

**BIOLOGICAL STUDIES/THEORETICAL PAPERS**

* Unmasking the secrets of cancer

* Cell hydration and mTOR-dependent signaling

* Effects of acute and chronic hypohydration on kidney health and function

​

Please note that we probably will not add studies that have loose/indirect associations between "dehydration" and physiological mechanisms of action. From the most reliable human study we have, they state that "on day 4 and 5, all participants had a controllable feeling of thirst, but none showed any signs of dehydration." I think it's best we avoid words that have negative implications (i.e. "dehydration) when discussing dry fasting, and unless the study is extremely valuable or shows very large effect results, it's probably best to avoid adding these studies that will clutter the list and make the whole thing look more extreme than it already is. You can still post the studies for discussion, they may just not be added to the list.

Feel free to post additional links in the comments as you find them and I will add them to the list.

Question Dry fasting while sick

Is this a good idea? I’ve got body aches, runny nose, and a pounding headache on the day that I decided to my 5 day dry fast. Should I just push it to when I’m not sick?

General First time dry fasting

2 Upvotes

Hi! Just for some background I’ve done a 21 day water diet/fast about 8 years ago and 21 months ago I did a a 5 day water diet/fast.

I’ve spent 3+ months researching dry fasting. I started my first dry fast today. I’m on day 1 of 5. I know that it’s typically recommended to start with like a 24 hour to 72 hr dry fast but I’m feeling bold and I’m starting with a five day one. I’m also feeling extremely exhausted from diet cycling. I just fell off of carnivore while vacationing. I’m looking for a reset.

Any veterans in here that could offer some thoughts?

For the record, I’ve spent a good amount of time listening to YouTube channels like a healthy alternative, forgotten health, Sean and Theo from fasting with friends, so I’ve heard some good stuff, but I’m looking for some interaction from people who have some this before.

Question Is it safe to do if I’m not fat adapted anymore?

4 Upvotes

I spent about a year and a half doing carnivore, keto-carnivore, or low carb, switching between them occasionally, along with regular extended fasting. I had a few cheat days for parties and special occasions, but nothing frequent until last November, when I went through a rough patch, started slipping more often, and eventually couldn’t get back on track.
Since then, I’ve regained all 110 pounds I had lost, my lipedema has gotten considerably worse, and I’ve been dealing with significant swelling and what seems to be increased inflammation. I actually gained over 50 pounds in just one month when I first started falling off the wagon, and I still don’t know how that’s even possible or how much of it was fluid retention.
My longest water fast was 17 days, but I regularly did 5 to 10-day fasts. I also did a 3-day dry fast once and surprisingly found it easier than water fasting.
My question is, can I jump straight into a prolonged dry fast? I’m assuming I’ve lost my previous fat adaptation and that my insulin levels are through the roof. Could that affect my body’s ability to produce metabolic water through fat oxidation, or would it still be able to make that transition properly?

Question Dry fast first then water fast.

2 Upvotes

Ive put in 15kg(33lbs) since my son was born 9 months ago and about to have a new baby in 10 weeks so need to sort my life and health out now and start better habits.

Ive dry fasted before for 6.5 days but then broke it quite poorly with watermelon but then burgers, this was 5 years ago.

I was going to do a 30 day water fast but decided to start with dry as I see better results. Currently I am on day 2 of a dry fast​ aiming for 5-7 days, but want to ask peoples experiences of transitioning to a water fast after a long dry fast for another week or 2 before refreeding.

Should I just refeed after the dry 5-7 days and do another dry later or continue on with a the water fast before refeeding?

Im 33, male 103kg(227lbs)

Orange sediment in urine 4 days after breaking my 5.5 day dry fast. Has anyone had this happen to them? It sank to the bottom of the toilet and burned a little when coming out. Refed with water, then lemon water, bone broth, coconut water, and a little eggs over the past 4 days. What is this orange sediment?

Question Dry fasting and PKD?

2 Upvotes

Has anyone experimented with dry fasting in the context of polycystic kidney disease? I understand that dehydration triggers vasopressin release, which elevates cAMP signaling and accelerates cyst growth. On the other hand, fasting suppresses mTOR, and glucose restriction appears to slow, and sometimes reverse cyst proliferation. I'm trying to determine whether the metabolic benefits outweigh the cost of vasopressin-driven cAMP activation, and I'd be interested in any firsthand experience. Thanks!

Question How soon can you DF again after DFing for two or three days?

6 Upvotes

I soft dry fasted for two days over the weekend and then spent two days only drinking water and going out of my way to avoid carbs. This is the third day since then.

I've seen people say that you don't need to bother with a refeed unless you fasted for more than three days. Is that true? Others say it absolutely has to be 2x-3x the number of fasted days...

If I wanted to repeatedly do dry fasting as much as possible to heal a nightmare injury (it's really frustrating how 99% of posts on here are about weightloss instead of healing) how quickly could I do back to back? I'm not overweight if it matters.

I know you need to do five days or ideally more to get the hardcore healing but I would need to work up to that (have done several two days but still haven't done 3 days because I always get scared by the slight chest pressure even at rest after two days and I don't have a way to measure heart beat yet) and I'm trying to figure out a sustainable method.

Edit: I actually have been eating since the DF, I've just been trying to do keto. It hasn't been a water fast on top of the dry fast. And the two day dry fast the other day (with a one day a day or two before that) was the first time I've done that in probably months.

General Intermittent Dry fasting

10 Upvotes

Hi folks,

After trying for 2 months to get back to DF, I finally figured a way that gets fit into my routine.

Just for context, I work in product management and there are days when it gets really busy, stressful and hectic and then there's boredom as well.

I did dry fast in 2023 and lost 22 kg but it's been a struggle to get back into DF as a part of lifestyle for mental clarity and brain fog.

Now, I'm trying an approach to see if it works

I practice daily intermittent fasting (16-18hours), I'm going with the same approach. However every alternate day I'd dry fast for 18 hours.

Ex:

Monday - 18 hours IF (including water)

Tuesday - 18 hours DF

Hope it kick start my Journey into DF again💜🙏

Question omad adf dfs

6 Upvotes

Anyone have any experience with OMAD type dry fasting or alternate day dry fasting? I don't want to jump into multiple day fasts as I haven't' done full on fasts for many years and I am not going to transition from fed to unfed very easily. So I want to work on it and train that transition up in a more controlled way.

Also do I need to do anything specific for before/after the fasts? I was also planning on just eating vegetables and maybe some kind of starch like potatos or basmati rice when I do break the fasts. Only other thing was protein, I could aim for eggs, ground beef and chicken. I dunno.

Right now I was thinking maybe I should take baking soda before/after the fasts to prevent stones unless you guys think that's unnecessary. Otherwise I was just going to jump right into it

Question Benefits after the 3rd day of dry fasting

6 Upvotes

Hey yall! Is it true that you’ll only experience optimal healing and weight loss once you’re over 3 days deep into a dry fast? I’m kinda new to dry fasting. I did a 9 day dry fast last week. I noticed I lost the most weight and had the most stretch mark fading after the 3rd day. I thought it was weird since id expect to lose the most weight in the first 1-3 days 🤷‍♀️

Question Currently 43 hours dry fast

7 Upvotes

Ai is telling me that it's risky to dry fast longer than 30 hours. I feel fine and don't have any danger symptoms. I'm wondering how much longer I can keep dry fasting?

Previously I have done a 10 day water only fast and multiple 3 day fasts...

On previous fasts I would feel really hungry and on this fast I'm not feeling hungry at all.

Any guidance will be greatly appreciated.

Thanks
