For anyone who has done a 3-day water fast

For those who have actually done a 3-day water fast, what was your experience like? What were your results? 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? 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.

Lost 10 pounds in a couple weeks with intermittent water fasting

I haven't been tracking it, and I'm not going on an extended fast, but instead I am eating sometimes and sometimes not, sometimes just drinking water only for up to 24 to possibly 36 hours, staying busy.

Meanwhile when I do eat I keep it to bacon, beef, beef jerky and beef sticks from costco, and eggs, mostly, along with some coconut oil. Because of the very limited diet with low carbs, I'm probably experiencing ketogenesis (body converting to fat for fuel instead of carbs). It's incidental, I'm not trying for it or going keto or anything.

How I did it is I stopped buying food, except for some bacon and beef jerky. I stopped buying milk, besides half gallons of a really high-fat milk at 8% milk fat I got from sprouts.

I'm not really depriving myself of food or suffering (although I'm mentally used to going hungry during fasting), but I'm not experiencing any side effects at all, nor am I having any issues breaking the fasts, because they aren't very long.

But when I get hungry I noticed it was boredom more than anything, and a 100% grass-fed beef stick or even just a sparkling flavored water (I'm drinking La Croix from Sprouts, zero flavorings or ingredients, just "naturally essenced"), I found that these La Croix satisfy me, proving the hunger was mostly boredom.

Just weighed at 10 pounds lighter, and it hasn't been long, maybe a couple of weeks. I haven't been tracking it. Approaching back to my ideal weight, although I'd like to go about another 10 pounds.

I've done long water fasts before and lost a lot, but I wanted to share this experience with extended intermittent fasts of only a day or more (24 to 36 hours), sometimes half a day (12 to 18 hours), without tracking it.

It's not 0 carbs either, I ate some nuts until I ate them all.

Is this supplement all I need when doing a 14 day water fast?

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.

How many days can a person fast without electrolytes?

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.

13 Day Water Only Fast (Lost 24Lbs)

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.

i need motivation to continue

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 need more alkaline water to do this

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

How do you get back on track after a really bad month of eating? Should i do water fast?

I recently moved back into my dorm after spending a month with my parents during the holidays, and honestly, it was a really bad month for me when it came to eating. I was eating pretty mindlessly and stopped caring about my usual routine, and I ended up gaining around 5 kg from the weight I had worked really hard to reach.

Now that I’m back at my dorm, I really want to get back into a consistent routine, but it feels surprisingly difficult after basically letting go of everything for a month. I’m active and normally enjoy boxing, running, and working out, but I’ve kind of lost my motivation and consistency with the eating parts since my progress has been ruined.

For anyone who has gone through something similar, how did you actually get yourself back on track after a long period of mindless eating? Did you just return to your normal routine and let things settle naturally? I’ve even wondered whether I should do something drastic like a water fast first, but I’m not sure if that would actually help or make things worse. I’d really appreciate any advice!

I’m documenting a 100 Day Fast (On Day 80)

Aloha,

I started an Extended Fast back on May 23rd. I was 261lbs as of May 23rd. As of Today I am 188 lbs.

I want to start off saying that I am not saying anyone should copy me or do what I am doing. At the end of this I plan on getting monthly dexa scans too see how much and what I gain back (I did not have the foresight or think people would care enough to spend the money on one before I started this sadly)

Currently I am having electrolytes, multivitamin, potassium and magnesium. LMNT (for electrolytes right now).

I “lift” weights every day but it is very very light and I am very careful not to tear the muscle/tendons. I am just trying to stimulate the muscle so my body knows I’m using it and too not lose it (no idea if this actually works, but that is the theory)

There are a lot of benefits & risks (even some that people wouldn’t even think of) that I plan on going over on things like Youtube/Patreon.

ALSO so if you saw my original post yesterday. I did not realize ChatGPT edited the crap out of the photos so I found an older video and posted the before and after video on socials. And then I spent way too much time making this stupid graphic

I will try to answer as many questions as I can here.
I post videos daily on IG/Youtube daily. My patreon is completely free where people can optionally sub. That is the best way to ask questions because tbh… lot of negative people on all platforms (lot of good too) but at least on Patreon you have to make an account to tell me I’m terrible haha.

I will try to check this a couple times a week and answer questions. But I do not consider myself an expert on the matter. But maybe 1 or 2 things I’m doing can help you on your fasting journey.

Need advice staying consistent with water fasting

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.
