When I tried to fast for more than 48 hours, my heart started to beat really fast when I tried to go for a run. Is anyone else experiencing this? Do I need to worry and avoid fasting for longer than 48 hours? What could be causing this? I have fasted for 48 hours in the past without any issues I don’t understand why this has become and issue two years later. For the past two weeks, I’ve only been fasting for 19 to 24 hours, but my arms are constantly aching, even though I haven’t been working them out. Do I need to stop fasting?

I’m 29yr old female 5’8, my last weighing was 3 weeks ago and I was 215lb.

Wearing the same shirt. SW: 133kg CW 103.5kg GW: 75kg Fasting routine: alternate day fast. Low Carb diet.

I'm new to all this. I'm 49 hours into an 84 hour fast. I never thought about electrolytes. Also should I maybe take in some salt. I'm a waiter and did 20,000 steps today. I'm going to stretch and do abs tomorrow and then I work tomorrow night. Just a short shift. Probably about 10,000 steps.

I'm pretty seasoned with fasting. Been doing OMAD for three years now, plus a couple longer fasts up to 5 days. I'm used to hunger pangs and even enjoy them. Until recently, it's been a while since i've felt them as my body has been so used to not eating they had basically disappeared. I had to quit fasting for a month due to a surgery, but quickly after I picked it up again with little problem. That was until I got the flu a week ago. My appetite completely disappeared until it came back with a burning passion once I started feeling better. I hadn't fasted for the last three days I was sick because I decided my body needed food to heal. Everything I ate during that time had 0 added sugar and was healthy as possible. I eat pretty healthily on the most part anyway so it wasn't any major change. I was completely ravished when the sickness ended, but I didn't listen to my screaming body because I wanted to get back to my fasting ASAP in fear that my hunger will only grow worse if I continued to feed it. That day was horrible, I could barely fall asleep (which i'm used to when fasting), but it was the stomach pain that was the weird thing. I NEVER felt stomach pain like this when fasting. It wasn't simple hunger pangs, but an actual stomachache. It was disabling to the point I could barely move, but i'm sensitive when it comes to stomach pain (other than hunger pangs which I like) so maybe I just perceived it as horrible. I have an iron willpower so I managed to tough it out that night, but when I woke up in the morning it had gotten so bad I had to race to the kitchen to grab a bag of nuts even though I wasn't even mentally hungry! I also grumpily had a bag of cereal as I realized that the food was actually helping. I only ate for the pain relief. About twenty minutes later, the pain vanished.

I tried to fast again the next day. Same thing happened. That time I had to get myself some food at midnight (which I NEVER do.) I ended up eating a whole days worth of food just to soothe my stomach, which then again vanished after I ate.

Since then i've been eating two to three meals a day which I absolutely despise but my appetite just won't go away and i'm scared to get another horrible stomachache. Today I tried fasting again and I got another stomachache. I had a small meal a few hours ago and I still have a stomachache. I dont want to eat, im not mentally hungry, but I have a feeling it'll once again get rid of this awful pain.

Does anyone know what tge hell is happening? This isn't hunger pangs, it's an actual stomachache. I'm a healthy young woman, slightly underweight due to prolonged fasting and calorie restriction which i've since been eating a healthy amount this past three months. I'm used to never being hungry and being barely able to eat a full meal so this is scary for me. I love fasting more than anything, I don't want this stomach pain to make me stop :(

SW: 250 CW:173 This wasn’t the best way to start my fast, idk if should include the hours I sleep into it but yeah. Started at 2:30am, slept in late, woke up at 12 pm ish. I have gotten to 24 hrs before as a water fast, but I just can’t stop crying. I’m very emotional reaching the 18 hr mark. I hate my body so much and Im trying not to get discouraged and end the fast early. I’ve already lost so much weight from fasting but it feels like it’ll never be enough, like I can’t let myself be proud. May just be that the only motivating factor I have right now is to look like the women my bf checks out (unrelated but I’m just in a bad way.) Just hoping to hear some kind words, or maybe share how your day is going? I hope you all are well.

Hi everyone, I’m a mom of three and wanting to do extended water only fast of 21 days for religious reasons. I do OMAD regularly. Any moms here have advice for taking care of home and family and prepping meals while doing an extended fast? I’m not worried about energy or anything, more about not giving into cravings. I’m pretty sure from what I’ve read here that the first week will be the hardest. Also, I have to break my fast on day 8 for an event but was planning to do OMAD for it and try to eat as LC as possible to get back into fasting after the event. Do I need to be worried about re-feeding syndrome then?

Or will I need to edit the start time come morning to properly account?

So can someone explain/ share what is the benefits of 21 day, 30 day, 45 day fasts vs. 72h or 5, 7 day fast done multiple times in a row, I am honestly very interested in the science and a fellow fasters experiences and opinions regarding this topic 🙏

Hiya! This is my first time posting here and I want to try my hand at fasting to lose weight, but I'm not sure where to start or what to do? There's different ways to fast, but which one is easier to do, what should I do during and after the fast, and how long should it be done before I start to see results? I feel like it's better to ask here where I could talk to people directly that know about this stuff already :)

So I'm already in 41hrs of my 720hr water fast. It's very hard not going to lie...it's more like a mental game then anything else.. I'm 23F weighing 140 pounds my goal is to feel better also to lose weight. My target weight is 108 pounds or 116 pounds.... how do you guys stay motivated on a long fast like this to be honest I'm struggling with my life any advice 😅

Hello friends,

I just broke a fast of approx. 36 hours. I ate my first meal at 13:00 hrs and had severe diarrhea at 19:30, just when I was about to have another meal. I had no issues or tummy-ache until I went to the bathroom. Lots of sweat. It was painful, long lasting and very, very awful - I almost passed out! Obviously it is about what I ate, so I would like to verify with you in order to find out what I did wrong:

I started with a very small mini-meal without any salt: Home-made bone-broth with a tiny bit of minced beef, some mushrooms, a few snow peas, paksoi and a bit of leek - all of which I boiled in the bone-broth. After a little while I had a full meal with the same bone-broth (with salt), chicken breast filet, the same veggies and two table spoons of black beans - all of which I boiled in the bone-broth. I topped it off with a handful of raw nuts and some raw-milk kefir-yoghurt with a bit of honey and sunflower seeds & pumpkin seeds (which I lightly roasted first).

I was hungry, so later in the day I had more nuts and a cup of cottage cheese with honey.

What did I do wrong? Too may nuts? Was it the cottage cheese?

Thank you very much for your feedback!

M26 97kg First time doing over 24hr fasting and while I can ignore the hunger quite easily as I've done IF, high calorie deficit in the past, the headaches and the feeling of being distant are getting to me as I near 48 hours so I went out and bought salt capsules, wondering what quantity of these I should to aleviate the dizziness

Thank you 😊

Did anyone get rid of eye floaters and visual snow through fasting? If so, how long did it take?

I know I post this comment way too much on this thread, but again, absolutely support this. Yet on the other hand, create a lifestyle change. Don't call it a diet, don't call it a system, or what this generation loves to say "hack" (smh). Take a look at your patterns that you're currently involved in. Understand how much you put in versus how much you put out. When I started my fasting journey, it initially completely detoxed my system. You will be absolutely shocked by the 5th day what your body is expelling. Then fast forward 3 years. Every time I fast, yes, I lose significant weight. After every fast, I feel motivated because I feel better. Yes, I've tended to cheat because I believe I can drop it again without fasting. Now last year, after my last major fast of 2 weeks (water, supplements, and the occasional cheat of a low-carb energy drink), I realized I really needed to get serious and make a full turnaround. Not just settle for "I just lost some weight" because I know I'm going to put it back on. The biggest saving grace in my life has been cardio. I am fortunate enough to have a treadmill and workout equipment. Don't focus on muscle gain, don't focus on sit-ups, don't worry about all that. Start with cardio. 15 minutes a day to start with consistent non-stop cardio. Conversational pace (ability to talk and still be understood while moving). I did that. I started out doing 15 minutes twice a day. After a while, it became easy. I've been transitioned to a routine of 3 and 1/2 mph for 1 hour twice a day. When I wake up, I start my day with 25 to 100 squats. But when you wake up every day, don't let your mind stop to think about anything, have a clear spot next to your bed for you to literally roll out, stretch, and start doing squats. Yes, squats are also a funny cardio if you have access to nothing else and it's difficult to get outside safely. But I promise you, once you get that figured out, you understand what it's like to focus solely on yourself and nothing around you. During this journey, I took a journal and wrote everything in my mind. It helped me clear up anxiety and get stuff out that I needed to get out. It's part of the process, I promise you. During the day I would look at every calorie I consumed versus calories burned per workout. I didn't look up no fancy plans, I took a look at what I needed for my own health, wrote down everything, and I always knew I'd be out about -150 calories a day. Yes, that's, the most health practitioners say, not healthy one bit. But when you're consuming clean food without added sugar, you will discover that you're going to start feeling better and you don't need to eat a lot. For me, that consisted of prepped mixed kale salads (Taylor Farms), kimchi, eggs, white protein (chicken, pork chops), bacon as a snack, and Quest protein bars. I realize that I can make a giant plate of food without barely consuming any carbs, feel full, and struggle with actually eating enough food because I still knew I couldn't be too much in the negative calorie count in a day because the last few hours of the day, if you're still staying active, you will actually cause yourself to completely drain. When I got to that point, I felt so confident. I stopped looking for outside sources to validate me. My initial goal was to get in shape so I could get laid, lmao, but as my journey took off, by the time I got to the point of confidence, getting laid had completely vanished on top of all of my bad habits, cravings, and addictions. I promise you, you will achieve your goal. But create your own goals and stick with it. Also, tips: Don't start a fast if you ate a mass amount of sugar the day before. Give yourself 3 days to cut back on the sugars and carbs, let your body get into a ketosis state. You all thank me extremely. Or just go for it and have fun (and I mean it because it's all about the experience), have fun with the body and mind aches. To me, after fasting my first time, I didn't understand it, but as time went on, it was kind of a fun experience, but it was an experience to see how much I could push myself. Until I finally told myself, stop fucking around, get serious with your life and be healthy and eat what you need to eat, not what you want to eat. Now, though, what I need to eat is the only thing I want to eat and nothing else truly sounds good to me anymore. Good luck, brother. You got my support, reach out to me anytime if you have any questions or are curious about what's happening during the process. Lastly, most importantly, understand the state of your health prior to a fast. Make sure there's nothing going on wrong that fasting can severely affect in a negative way. Make sure you are prepared for your mind to go into a fight mode because it will, and it will try to convince you that you need to eat. You're going to start pointing out every little wrong thing every day that's going to happen and convince yourself, "Well, my body's telling me I need food." Uh, well, of course, it is. It's in a fight mode. Good luck, brother. You got my support.

It’s hard to explain why I need to fast as someone whose blood pressure is volatile and frequently very low but I need to do it for a little over 24 hours. What are some ways to keep myself upright and the blood flowing to the brain? Any help staying alive appreciated.

Started this unintentionally as I just haven't eaten since returning home from a work trip. Now 72 hours in, and I feel fine. Stomach grumble on occasion, but no hunger pains. I've been walking about 1.5 miles/day with no weakness or lightheadedness. I havent supplemented with electrolytes or salt. At some point is it wise even though I haven't had any symptoms?

I tried googling and searching for the answer to this but can't find an answer.

If you are water fasting and you drink black coffee and your blood sugar spikes 5 points is that breaking the fast? The blood sugar can't spikes at all to remain in a fasting state. Am I right? Or if it's still a low number is it fine. My glucose for some reason has been 60-69 which is low and with black coffee goes up 5 points.

I’ve been following this thread for a few weeks, and I’m growing more comfortable with fasting for longer periods. A few years ago, I weighed 340 lbs (154 kg) and was managing Type 2 diabetes. After working hard, I lost over 100 lbs (45 kg) and got down to 220 lbs (100 kg), which helped me reverse my diabetes—my A1C dropped from 8.7 to 5.4. Unfortunately, I became disabled four years ago, and I slowly gained back 40 lbs (18 kg), putting me at 260 lbs (118 kg) and back to pre-diabetic status.

With high insulin resistance making it especially tough to lose weight, I’m determined to take control again. My goal is to lose 80 lbs (36 kg) to reach 180 lbs (82 kg). The most logical solution I see is longer fasting, but my doctor is cautious about it. I’m currently doing 16:8 fasting but would like to push it to 24 hours and then see if I can extend it gradually. I’m a bit nervous and tend to overthink it, so I’d love any advice, especially from those who’ve managed diabetes while fasting.

We all have heard the horror stories from people who don’t know enough from fasts “stop your gonna destroy your metabolism” and all the other rhetoric but from an unbiased stand point has anyone ever had any real negative experiences?

26, F, CW is 276lbs, 5’9. I’m also 9 months postpartum. So, say I do extended fasts (24-48 hours) every other day or so until Thanksgiving (Nov 28th in the USA). I drink water, diet coke, and chia seed water every day (1-2tbs of chia seeds soaked in 1-2c of water and soaked over night). How much can I realistically expect to lose? Ideally overall I’d like to lose 80lbs and be under 200lbs again but I know that likely won’t be for a hot minute.

Hello All,

I am new to fasting and would like to lose 40lbs

Can you tell me if this method of doing 48 hr or 72 hr rolling fasts will get me to a 6-pack?

I want to do 8 hr refeed during my eating window

The once you start a fast you become obsessed with cooking videos on YouTube??? No joke when I start a fast I can’t help but click on videos of the tastiest looking food I have ever seen

I currently do 20:4 and it's going quite well. I eat at about 4pm, and recently I've been feeling very hungry through the day. Would eating a dill pickle spear break my fast? The jar says 0 calories, but I'm pretty sure that would break a fast.

Currently attempting a 72hr fast and wanting to drink pre workout with 700mg of carbs before exercise.

For the extended fasters especially….whats the longest into a fast did you have a BM?

I gained ~40lbs several years ago and have been yoyoing the top 20lbs of that range for years now. I recently regained 10 of those lbs and was feeling so defeated. When I found this community I felt encouraged to keep pushing and decided to give this a try beginning that same day. For background, I regularly do OMAD (love it for maintenance). I tried a 48hr once a couple years ago and didn't think I'd ever repeat the experience. I think at that time I had a lot of fear about trying something new, but this time when I saw how long people were fasting in this community and the benefits they were getting I decided to go for a 72hr fast. Well I made it to 72hrs, read The Obesity Code, continued to browse this sub for inspiration, and felt so proud/happy that I turned it into a 5 day fast (stopped at 118hrs bc I started late the first day and didn't want to eat too late). I walked 10-15k steps daily and did not have any major physical issues. I lost the 10lbs I had regained, after eating I regained 1lb. I am elated and plan to do a few more of these until I get rid of the last 20lbs. Thank you all so much! I couldn't have done it without this sub and this post is my way of paying it forward to the next person thinking about giving it a try. You can do it!!

I did a 48 on a whim about a month ago and loved it and found this group. I'm 36 hours into an 84 and feeling good. I think the thing I learned from this group (and you tube) is that you need to make this a lifestyle. So when I'm done this time I'm going to do IF. Maybe OMAD. Not quite sure yet. Anyway keep on keeping on. I feel like this is the thing I've been looking for for many years.

I’m new to fasting. This is day 5 of intermittent fasting. The first 4 days were 12 hours and day 5 was 16 hours. My weight had increased each day. I’m not being irresponsible during eating hours. Is this normal to gain weight at the beginning until your body adjusts? Or am I not being patient enough since I just started? Or maybe something else? Also, I haven’t seen any change in my glucose levels. They are still around 175-180.
