Dry Fasting. Is there any science to this?

(Doug) #133

I’d say yes - figuring there’s a little bit of water in bacon, if it hasn’t been heated enough to drive it off. Probably would have to press fairly hard.

There definitely are liquids in the body that are not water. I thought of this when reading your first post, where you mentioned fat-soluble fluids. Then I wondered about emusified fluids, and thought, “Uh-oh, this is going to get messy.” :slightly_smiling_face: If we’re really looking for the water content of the body, then we need to separate the water out from the other stuff in emulsified fluids.

The one emulsifier I know of is bile. Rhymes with chyle, formed in the small intestine with bile’s help when fats are digested. Chyle goes into our lymph fluid along with a bunch of white blood cells, and a LOT of water - just learned that today. Are we mistaking other fluids for water when we talk of the body’s water percentage?

(Bunny) #134

Yes! Bile is like the bodies laundry detergent (emulsifier) to break down fat (another Dr. Berg analogy)!

I think where the confusion comes in, is that we think when we drink water that we are simply water thus we are a certain % water but not so simple, water is in constant ingress and regress through out the body but not it’s primary composition! Like a cup, water does not become part of the cup, it is simply a vessel that can hold a fluid!

(Doug) #135

Okay, I think… :slightly_smiling_face: We’re definitely the sum of many parts, not just one part. There are certainly practically endless non-water things without which we’d be dead. Still, when we’re talking about fasting or dry fasting and refeeding, electrolytic balances, etc., then water is a huge deal.

I think I’ve got a “lot” of water in me, i.e. still a pretty big boy, and I’m tempted to try dry fasting for a day or a very few days. What appeals to me is the notion of “mixing things up,” and some of the possibilities raised by the study - that an increasing osmotic gradient between fluid in tissue and in the bloodstream could cause extra fluid movement out of the tissue, relieving congestion and improving circulation therein. I’m guessing that this almost never happens if we’re totally hydrated or nearly so at all times.

Also: "Among the 6 circumferences measured in this study, WC (waist circumference) changed most dramatically. The total decrease in WC during FWD corresponds to a huge decrease of the abdominal volume within 5 days. Such a massive and rapid volume decrease can hardly be attributed to the reduction of visceral fat. In view of the total weight loss, urine discharge, and the additional insensible water loss, this volume decrease could be mainly attributed to elimination of edema fluids from the abdominal organs. According to these results, the terms ‘visceral fat’, ‘central obesity’, and ‘abdominal obesity’ or ‘adiposity’ used in various reports may need reconsideration. The risks related to increased WC might be related rather to the edema than to the fat tissue of the abdominal organs."

That last sentence - wow. Some serious speculation there, and this is probably the place where people are thinking, “All right, Doug, put down the Crack pipe…” But I do like screwing around with stuff.

I think I understand it, but I can’t get over why someone would pour water on perfectly good bacon.

Here’s my n=1 for a dry fast.

I did a 24 hr dry fast Tuesday morning until Wednesday morning. I was 189 lbs Tuesday morning and 185.5 lbs Wednesday morning. A loss of 3.5 lbs. I consumed nothing for the full 24 hours. No food or liquids. I then broke my fast in the morning with a leftover double chicken bowl from Chipotle with sour cream and cheese. Had a plate of ham and cheese for lunch. I topped the day off with dinner: a 16oz hamburger steak pan seared in bacon drippings, lard, and its own “tallow”. I then added heavy cream to the leftover fat in the pan and deglazed the fond to make a sauce and poured over the steak turning it into this amazing, creamy Salisbury steak type meal.

This morning (Thursday) I was 187.

So even after my day after of feasting and fluid intake, I can assume my 1 day dry fast netted a 2lb weight loss.

During my fast I had a few food/drink cravings that were more habitual than anything. I ended up just going to bed at 9 PM (which is early for me) so I didn’t have to deal with any more cravings!

Overall it was a great experience for me. If you do try a dry fast, just listen to your body. I didn’t experience any negative effects, but that doesn’t mean you won’t. If you feel bad during a fast, break it.

(TJ Borden) #138

I have a pound of hamburger in the fridge I was trying to decide what to do with. Problem solved, because that looks AWESOME

(Justin Roberts) #139

You need to find some of this if you don’t have some…


It’s fantastic on just about all meats.

But the gum can spike your insulin level.


Did my second dry fast went 30 hours before I felt the need for a few sips of water (I talk a bit for work and my throat was dry.) Finishing the day out with just those sips. I have a bit of a headache and I am tired *not to sure if that is related or not). I will say starting around hour 26 or 27 I felt a little foggy and my brain was not as sharp as normal. But that seemed to pass until about an hour ago (so that would be around 32 hours after any significant water intake.) I’ll refuel after I get home and see what the scale says. I did this to try to eliminate inflammation I developed a week ago Monday after being glutened. Between yesterday morning when I woke up and this morning when I woke up I dropped 3.3 pounds. I’ll be glad to get home and drink some water.

Okay, updating this Wednesday morning: total loss for 35+ hour dry fast before drinking was 4.2 pounds. After refill I am down 3 and half from when I started but up 3 and half from my pre-glutened weight. So not sure if I am still dealing with the inflammation from that. I am going to go back to water fasting today. I don’t know that dry fasting has any appreciable benefits that I can measure for myself. I don’t think I will do this very often. It did seem to help with some of the inflammation so that’s good. Not sure it burns more fat than I do when water or fat fasting.


Oh, and I woke up and my face is swollen today. Not sure if it’s rebound effect or a sign I am sensitive to the pecans or sheep’s milk cheese I ate last night.

For some their very thoughts can spike insulin but it is rare :open_mouth:

“No significant differences in the blood concentration of glucose, insulin and GIP or hunger were observed…”

when dry fasting your body break down old cells for energy. break down your fat cells to get water, that’s why you still pee, even not drinking.
after 3 days dry dry fast your system is reset.
dry fast is on another level, than water fast.
I have done 7 days water fasting this year.
3 times 3 days dry fasting, I have lost total since 1.1.2018. 24 kilo of fat. I am 58 old man.


I’m a 42 year old pescatarian triathlete, sun gazer, and regular faster. I have been intermittent fasting 20/4 year round, and dry fasting for 11 days 3 times per year, for approximately 6 years. I discovered dry fasting after being diagnosed in 2012 with Fibrillary Astrocytoma. I cured myself in under 6 weeks (time between scans). Seizures stopped inside 7 days. No medical interventions used at all and no relapse since. I’m currently 72 hours into my 11 day dry fast and all indicators are normal (as per usual). I cannot quote the science, however, I can speak from experience that dry fasting (for me) has been both safe and life changing.

(Bunny) #147

Drink water when you are thirsty!

(Geoff) #148

Proathelete, Can you please share more details about your 11 day dry fasting experience? Are you active during such a long dry fast? Do you ingest anything? can you please Share any articles from your research? Tips? What indicators are your speaking of that are all normal? Thanks!

I am currently 48 hours into a fast, with the last 28 hrs being hard dry and expect to transition back to water after 40 hrs of dry. I will probably end the fast after 4 days. I feel my energy levels dropping after 24 hrs of DF but a “fasting euphoria” coming on. I also feel like i have crossed into ketosis due to very limited hunger cravings.

(Justin Traer) #149

This user signed up, stayed for 5 days. Claims to have cured brain tumors with fasting.

S/he is dead or trolling. Overall, it sounds like terrible advice given they have ghosted this forum.


OR, I found the forum not very useful, am busy, and haven’t returned. But you do you. Have a great day.

(Justin Traer) #151

Fair enough. And a great day to you too.


So, I finally decided to jump in and try this. I did a soft dry fast on Sunday for about 16 hours and am planning on a 24+ hour hard dry fast tomorrow (I am water fasting today and Friday). I felt much better on Sunday than I had expected (I expected to feel super thirsty and dehydrated; I felt neither). The only negative, and I believe now that it’s due to how I ended the fast, was really bad leg cramps that night (after ending the fast with a regular meal and beverage). I hear that you have to carefully re-introduce water and I’ll be trying that this time.

I’ve just re-read this whole thread, and while I find the ideas intriguing, I’d really prefer to see more than just the one under-powered human study before making up my mind. I would really prefer a study with n = 100 or more, not a mere 10.

Furthermore, I’d particularly like to see a study discussing the difference in effects between dry fasting and wet fasting in humans. i just don’t see that the Papagiannopoulos study shows that dry fasting is an improvement over wet. Certainly, the claim that dry fasting is “three times better” is not discussed at all in that study.

The Papagiannopoulos study does at least prove the feasibility of dry fasting, and I am surprised that the participants were able to go five full days, because I didn’t think that was possible. So at least I’ve learned something useful. I’ve also learned that there is a protein named for the Fate who spins out the thread of life—that is a fact so useless that I’m probably going to remember it until the day I die (my brain works that way, lol!).
