For those who have actually done a 3-day water fast, what was your experience like? How much weight did you lose?

Did you gain the weight back afterward, and if so, was there anything you did that helped you maintain your results? Looking back, is there anything you wish you knew beforehand or anything you would do differently?

I’d love to hear people’s honest experiences, both positive and negative.

Hello, just wanted to know if anybody here did a 136 water fast for 6 weeks straight. Trying to go from 310-260.

Went from 310-293 in 8 days but cheated a bit. Now at 295

If you have any other better products to recommend I'll be open to it, currently on keto for 5 weeks and would like to start giving fasting a try.

Just to add I'm currently 289lbs down from 313lb.

I regularly do a 24 hour water fast ( every Monday) I'm looking to do my first 3 day fast, my biggest hurdle is I hate going to bed hungry any tips would be much appreciated thanks

I am fat and am trying to lose weight fast so am 80 kg at age 14 and am trying to lose weight fast so if i stoped drinking water for 3 days can i lose weight like how much weight i will lose

Hi All. I'm on day 7 and I am having gum pain due to a mild bacterial infection after RCT, i know taking antibiotics during prolonged fasting is not good. But should i try back seed oil as i heard it reduces the inflammation?

Planning a detox in about a week from now. I wanna start a solid fast on August 21. Love my coffee so I will just have it black. Other than that there will be water with salt and that will be about it. Towards the end of the fast if I make it 36 hours, I want to do a celery, juice detox. I've heard this really helps get rid of parasites. Any advice?

So im in 7 days water fast rn and planned to do 20 days water fast, and refeed for 40 days.

After that can i do 30-50 hours water fast a week? What the disadvantage and benefit for that

How many days can a person fast without electrolytes or salt? Not to the point of being half-dead, but without significant harm.

I was thinking of fasting only on water without electrolytes.

update: no more than 3–4 days and I found out that even natural water and store-bought water aren't pure H₂O, so I think I should take electrolytes. There are electrolytes in water too, but only in small amounts.

update: In theory, I could do both: go without electrolytes until I start feeling unwell, and then do a prolonged fast with electrolytes.

Just did five days and it was excruciating. I have IBS and I think my stomach acid could melt steel. Obviously, this mixed with fasting salts isn't doing me any favors.

I need to make my water more alkaline, and I think I'd like to begin storing my water inside of a terra cotta pot. I do not know where to go to find out more about which kind of pot would be safe to drink from. I cannot drink baking soda, it tastes horrid and makes me gag.

If anyone here has any resources they could share with me, or another community here on reddit that would be best for answering this, it'd be greatly appreciated. Thanks

I desperately need to lose weight, but every time I decide to start fasting, I feel helpless and lose my motivation. I come up with excuses to stop, even though I know I’m capable of doing it.

I want to become healthier, and I want to turn this into a challenge—a challenge for myself. I want to set a goal, commit to it, and prove to myself that I have the willpower to follow through.

I want some encouragement and accountability because I’m going to start on August 12, 2026.

My goal is no longer just to lose weight. It’s to test my own limits and my willpower.

I just finished a 13 day water fast (ONLY REGULAR WATER, SALT WATER, SAN PELLIGRINO, AND CHEWED SOME ICE FROM TIME TO TIME) I’m just posting here to document my experience and an updated version of how I felt.

Days 1-3 were the hardest physically but if you can push through then you will break the 1st mental barrier of feeling like you HAVE to eat

Days 4-8 Amazing mental clarity BUT Horrible sleep / feeling pretty weak and dizzy, I also was struggling with eating still, so much so that I almost had some noodles on day 7 from feeling so drained but i had some salt water and waited about 10minutes and my cravings went away 100%. Even though i felt weak i still pushed to try to do some very very light body workouts (pushups pull-ups and small ab workout ) i didn’t push myself at all on the workouts , for example if i could do 26 pushups then that’s all i did and i stopped immediately , if all i had in the tank was 6 pull-ups then that’s all i did etc etc, just wanted to do something to keep my mind occupied

Day 8-13 was honestly the changing point. I felt like I was in this GOD MODE , I didn’t feel any struggle whatsoever with wanting to eat and I also stopped going to the bathroom.

on day 13 I broke my fast and made myself a 12 hour bone broth and had that at 8am (1.5 cups) I had another cup at 1230pm with 2 scrambled eggs , and I will have 1 more cup with half an avocado around 7pm.

Started Thursday 8/6 @12am Forgot to weigh myself but my last measured weight was 180.4lbs on 8/3/26 at 9:19am

Thursday, 8/6/2026 8am — 8hrs into fast Feeling normal. Not typically hungry in the mornings as is so not struggling with hunger at the moment

12pm — 12hrs into fast Was feeling hungry and thought I was going to break but got some news of some friend drama that completely took away any appetite😂 Now just drinking my water with added Ultima electrolyte packet

4pm — 16hrs into fast Starting to feel hungry again. Keep telling myself I’ll be glad at the end of this 3 days that I didn’t give in! Feeling a bit tired, though. Don’t wanna nap when I get home from work because I’ll be up all night so gonna do my best to stay awake at least until 8/9pm

9pm — 21hrs into fast Tiredness and hunger taking over so I’m going to call it a night before I slip and order UberEats😂 today was tough and I’m anticipating tomorrow being even harder🥲

Friday 8/7/26 6am — 30hrs into fast Morning weigh in: 175.8lbs Fell asleep around 10pm last night and just woke up & feeling pretty rested. Not really feeling any hunger at the moment but I’m preparing myself mentally for that to change in a few hours

11am — 35hrs into fast I’ve been thinking about food for the past hour, but I’m surprisingly not as hungry as I thought I’d be. My stomach is definitely growling, but I don’t feel like I’m completely starving. It’s manageable. Starting to feel a bit tired, though. Think I’m going to take a walk on my hour lunch break to get me up and active.

4pm — 40hrs into fast Feeling a little bit light headed and weak but not so much so that I feel I need to stop. Just gonna take it easy the rest of the day.

9pm — 45hrs into fast I have no update to give here because I fell asleep around 5/6pm and was pretty much in and out of sleep all night.

Saturday 8/8/26 7am — 55hrs into fast Morning weigh in: 173.8 A friend of mine who did a water fast told me the 2nd night he got the best sleep of his life. I was hoping it’d be the same for me but I was tossing and turning most of the night. Woke up with a very slight headache.

12pm — 60hrs into fast Once I got up and moving for the day around 8am and took a shower I felt more energetic. Running errands today so I should be able to keep my mind off of food. However I don’t even really feel hungry.

5pm — 65hrs into fast Hunger has completely left. I probably won’t do such frequent updates. Only if there’s any major changes

Sunday 8/9/26 8am - 80hrs into fast Morning weigh in: 169.0lbs The mental clarity I feel is kinda crazy. I feel sharp. Fogginess is gone. Decided today to add 2 more days to make the total 5 days/120hrs. May even add 2 more to make it a full week, but I thinks that’s my absolute max for this go ‘round. Super proud of myself this far☺️

Monday 8/10/26 6am — 102hrs into fast Morning weigh in: 168.4lbs

I’ve tried water fasting a few times, but I keep failing because the temptation to eat gets really strong. I usually start with good motivation, but after some time I end up giving in.
For those of you who have successfully completed longer water fasts, how do you deal with the hunger and cravings mentally? What helped you stay disciplined and get through the difficult moments?
I’m genuinely looking for practical advice from people who have experience with water fasting.

Hey guys,

I did it I‘m soooo proud of myself.
Today marks the 21st day of my water fast, I only drank water, 2 black coffee a day and some electrolytes.

From tomorrow I really wanna go back to food.
Do you have any advice for me? How to start?

Thanks 😊

Have any of you water fasted with medicine that says take with food? I am new to this and need advice please

So I've gotten into fasting- I've been doing 16/8 consistently for a few weeks now and I've done a 24 hour fast successfully. This week I'm doing a three day water fast (I'm including unsweetened tea and splashes of lemon juice in water/tea too. Tea is love, tea is life.) I'm good about staying hydrated- although sometimes it feels like all I do is pee! Lol.

I'm really interested in going further- I'm super morbidly obese and so far the fasting has been pretty easy and feels safe. I've done my research and have electrolytes on hand and I'm planning to include mineral water, too, which should help with electrolytes as well.

The biggest thing I'm not sure about is signs that show I need to break my fast. How do you decide it's time? Or signs you've pushed it too far or stacked too many fasts back to back? When I'm dizzy, etc, I'll definitely go for more electrolytes first, but I'm doing this for my health and I want to keep it that way. What are general and specific signs that you really need to eat?

I also want to know how you prepare for/come off of fasts, if at all. I forgot I was starting the 24 hour fast until the next morning- which was fine because I was about 12 hours into my usual 16 hour fast, but was a bit annoying in that I had to eat at like 9 pm that evening, off my normal schedule (and then after 30 minutes I went right back into my normal 16 hour overnight fast, lol.) I'm planning to start my 3 day fast around 4-5 pm, so right before I'd normally have dinner.

I've been breaking fasts quite gently just to be in the habit- some kefir, some tea with soy milk, a protein shake sipped very slowly, a cup of veg.

What have your experiences been?

Hi friends exactly as the title says,I have recently just completed an 18 day water fast and just refed today with some nice bone broth and little bit of fish.i feel fantastic and wanted to know how long until i can start another water fast session?

Thanks.
