Today, I’m going to share some of the amazing benefits of dry fasting and water fasting There are over 50 genes that protect us from famine and drought and produce many health benefits. Fasting can help you lose weight, burn fat, and live longer. It helps improve cardiovascular health and can improve your blood sugars.
A study involving birds compared birds who ate food and drank water, birds who only drank water, and birds who were essentially dry fasting as they flew across the desert. The group of dry-fasting birds generated 6 times more water than the group of birds that drank water! The dry-fasting birds also burned more fat.
When fat is burned with oxygen from the air, it turns into water. The idea that we need massive amounts of water was developed from a campaign that terrified us of dehydration! You don’t need to overdo it with water; you just need to drink when you’re thirsty.
Dry fasting is a useful tool for weight loss, but you want to ensure you do it correctly for the most fasting benefits. Follow a low-carb diet for a while before trying dry fasting. Once your body is adapted to fat burning, you’ll find that fasting is much easier.
Try water fasting before attempting dry fasting. If you’re water fasting, you can consume water, electrolytes, supplements, and sea salt. If you’re dry fasting, you don’t consume anything.
One day of dry fasting is equal to three days of water fasting! Dry fasting turns off digestion and allows the kidneys time to rest, allowing your body to switch into repair mode.
After your fast, begin eating gradually, starting with liquids. Kefir and bone broth are good choices to break your fast.

I dry fasting 24 twice in week and go gym lifting more weights than normal and don't feel no pain no sore head and I tried water fasting afternoon feel very sore head and next day when no fast feel knackered and tired so I found dry fasting more easier
Oh yes it's true that since the bottled water companies came along, everyone all of a sudden needs to drink at least 2 litres of water/day.
I drive fast almost every day 8 to 9 hours and I noticed my stomach shrunk it got real small I can't eat a bigger portion of food which is really good so I'm spending Less on my grocery way less
Ive done the fasting drinking water and odd coffee. I am seriously thinking of a dry fast
How is this possible? How can we be without water more then 3 days? How?
I did dry fasting for two days I lose weight , bloated , back pain,leg pain ,insomia gone…Im very feel so healthy and I sleep well.. Thanks…
I'm on keto diet since several month. Did a 36 hour dry fast couple of days ago. No problem at all. When I broke the fast my body released a lot of garbage which I am pleased about.
Howeve since then I did a little research and some people say it out high stress on kidneys and may increase cortisol levels.
Grateful to have feedback from people on this! Maybe it is better to do a shorter dry fast 20 hour at most like Dr Berg suggests?
@Dr Berg, have you ever heard of Dr Alan Goldhamer the world’s authority on water fasting
I've started dry fasting regularly for one day (and two nights). The results are amazing. And I consistently lose a couple of pounds each time I do it. I'm feeling better all the time with more endurance and much fewer "old man" symptoms (I'm almost 57) I've noticed that I get less hungry with a dry fast. Just don't expect to be bursting with energy. I typically break my fast with homemade (live) sourkrout several hours before eating some eggs.
I've dry fasted for 5 days, while exercising and trying to be productive instead of laying around doing nothing but the fatigue is a major flaw. I found a better way: drink water, salt and tea one time a day after waking up or before exercise, then dry fast for for the rest of the day and repeat the process. It's a hybrid dry and water fast that allows me to stay mentally and physically sharp and I believe it is more effective because exercise greatly enhances autophagy.
Isnt the weight we lose from losing water?
Man when i dont drink water im so nervous kinda i'll strangle someone im also like dehydrated feeling dizzy in my head also
Christianity, Hinduism, Islam, I believe most religions have this. With a good reason too.
Hmm, according to the Phoenix protocol it's more advisable to start with a (short) dry fast and then switch to a water fast, not the other way round. So what's your take, Dr. Berg? 🤔🧐
Thanx
Starting dry fast now I will update in 24 hours
We dry fast every year for 30 days, 15 to 20 hours a day in Ramadan..
I was here!
Never do water fasting before dry fasting – super tough. Go straight in dry fast and live to water fast after, so easy !
So, we have all the genes to protect us from dehydration 👍
But our bodies are so stupid then when the drought comes to an end and we find a source of water, we have to drink it very slowly over a long period of time….
No one else see what a load of crap that is …. 😏
big water is tricking you into hydrating
Love it Dr, Berg, follow the Ketogenic diet to the tee, took Me 6 weeks to become fat adapted, water fasted for 5 days during easter holidays, the temptation was akin to Odysessus tied to the Mast of the Ship sailing past the Sirens haha, Now I see dry fasting as the new challenge I am currently 18 hours in. If it provides 3x benefits of Water fasting, this will be My go to every month.
Does anyone Know how to combat Thirst when doing a dry fast? I tried dry fasting once it’s the truth but the thrust is very hard to combat when u start
I love Dr Bergs idea's about water fasting and dry fasting
I wish he was a vegan as well😢
But i try to respect everyone's
Lifestyle
So basically Ramadan? 😅
I had a fat stomach. Been dry fasting on and off for couple of months. Now i can see my penis. 😂
People who are dying don't eat or drink for days at a time. How is this different from what they experience?
We do it every year for month in Ramadan from sunrise to sunset, no food no drink, it's the same concept, but the only problem is that people eat like crazy when they break there fast, so if they break the fast with reasonable good healthy food it will be perfect 👌
"Praise be to Allah for the blessing of Islam, praise be to Allah for the blessing of the Holy Quran, praise be to Allah for the blessing of dry fasting that Islam commanded us to observe for 30 consecutive days for up to more than 14 hours, and praise be to Allah for His countless and innumerable blessings."
Dry fasting = muslims how they fast no water no food until feast
Intriguing! This is definitely contradictory info from decades of what we’ve been told.
How people claim to do hard dry fast for 8 and 9 days without dying?
And what about dehydration?
They brainwashed us, oh! Sorry, they educated us. 😅😂.
Everything they push too hard is suss🤔.
On my second day of dry fast out of 3.
Every body is talking about fat loss but not know that it is a panacea for 99 percent diseases.
I did a 36 hour dry fast last recently out of instinct and was surprised that I urinated as much as normal and my mouth was constantly salivating.
Thanks for the info, Doc !
💛❤ Value ❤💛
Yeah. Early man was eating well if they ate once every 3 days. Why we need to eat 3 days.
Watching this to convince/motivate me to start my 3 day fast today 🤞starting at 94kgs so let’s see how it goes
Trying this today. I've made it through a 3 – day water fast a couple weeks ago. Think I will aim for 3 dry and then move to water for a few days. Aiming for a 7 day fast total.

"Please be extremely careful if you are considering dry fasting for weight loss. 🛑 Not drinking water forces your body into acute dehydration, which puts immense stress on your kidneys and heart, and decreases your blood volume. Losing weight shouldn't mean putting your organs at risk. If private coaching or expensive diets aren't an option for you, remember that you can use free AI tools (like ChatGPT or Copilot) as a safe, personal wellness companion. You can literally ask it to build a balanced, realistic meal plan tailored to your body without starving or dehydrating yourself. Please prioritize your health over dangerous shortcuts! ❤"
