Three days in and I'm up four pounds?

I've done quite a bit of fasting over the years, including one 50 day and several 30 day ones so it's not like I'm unaware of how it works. I'm used to seeing my weight plummet in the first several days, I don't think I've ever seen it do this before.

interestingly, at my initial weigh in before the fast, I just had my omad and drank a few large glasses of water so my weight was up a few lbs.

I have green tea, saltwater and black coffee as well as sparkling mineral water pretty liberally but didn't think they would cause this kind of shift.

I'm not doing this fast for my weight, just to clear up some inflammation and a skin issue that only seems to go way after several days of autophagy so it's no really bothering me, I am just scratching my head though.

Is this a normal?

why hunger comes in waves (and how to ride them without breaking your fast)

one of the biggest myths about fasting is that hunger just keeps growing and growing until you eat. it’s actually the opposite. hunger isn't a mountain you have to climb; it’s a wave that peaks and then fades away.

this happens because of ghrelin (the hunger hormone). it doesn't stay high; it pulses based on your usual eating times. if you can wait out that 20–30 minute wave, it usually disappears.

i was reading a deep dive into the science of these hunger spikes recently, and it explains exactly why our bodies react this way and how to "train" your hormones to stay calm during a fast. it’s a world-class breakdown if you want to understand the "why" behind the struggle:

for those doing extended fasts, how do you handle those mental hunger waves? do you drink black coffee, or just stay busy until it passes?

I’m getting tired of fasting

I normally do 20-23 hour fasts. Mostly OMAD. Does anyone every break there fasts earlier in order to give their body a break? I only recently gave up booze so that might take awhile. Maybe fasting will get easier?

🥳Happy Fasting Friday! I hope everyone fasting has an incredible weekend! I am going to live it up with decaffeinated coffee and Hibiscus tea tonight! 🎉 I never add anything to my tea, I always drink it plain. Recently I became used to black coffee and I love it straight up, too! 😁

What plain beverages will you enjoy tonight.

Black coffee and tea with zero added for me!!

Hibiscus 🌺 tea is absolutely delicious plain.

I don't understand NOT drinking plain tea.

I love green tea and hibiscus tea.

🎉🥳I will also enjoy some delicious fasting electrolytes! Thats when the party really starts.

Happy Fasting Friday!

4 days in…it’s kinda getting fun!

I’m finally getting into that groove! The first three days were horribleee, but the longer I go with this fast, the more “unstoppable” I feel, if that makes sense? I really hope I can make it through the 300 hours that I’d want to reach, that’d be a dream for me…but all in all, for right now, I’m actually happy and having fun!

I dunno if feeling ecstatic during a fast is a normal thing, but it’s how I feel right now ! 😁

Halfway on my water fast. What do you all take for vitamins/electrolytes on fasts?

I’m looking to go into this next 120 as safely as possible. Thanks! 🙏

Almost Done With My First Intentional 7 Day Fast 🥲

Honestly I could cry. I grew up with a parent who included me with fasts at a young age which ultimately screwed up my relationship with my body and food. Before I started I was so nauseous and had abdominal pains every time I ate for months and was so over how I was using food to cope. The clarity I gained from this week was amazing. I needed this more than I thought. I’ve lost 14lbs so far. I was able to keep up with no vaping// 27 days free as of today. I kept up with my water intake and my sodium intake and ultima electrolytes 2x a day and omg pickle juice which really helped even more with preventing the headaches and dizziness I felt on day 1 & 2. Day 4 was the worst, only because my stomach was hungry and not my brain. It’s been a while since I wasn’t emotionally eating or binging. And today was testing me a lot but I will push through. I will say I was a bit cold from time to time but that went away. I only walked maybe 4 times this week but no exercise, I will be more intentional next time. I do have a question. I want to begin rolling 72s. How would I start? Should I wait a bit after this fast or can I start immediately? How should the calorie intake be approached during refeeds? I am doing it for weight loss but also the clarity helped a lot. Thanks in advance.

My blood biomarker categories - Before, during, and after fasting

Hey folks! I shared how my blood biomarker categories changed over extended fasts in the past, and realized it might be a good idea to reshare them as there are some questions on this topic. Briefly, extended fasting is a huge stressor on the body, so it impacts many biomarkers.

I used InsideTracker’s biomarker categories, which combine 50+ markers into 10 health areas like Heart Health, Hormone Health, Inflammation and others. Each category gets a 0-100 score (100 = best) based on how close each marker is to its ideal range. For example, Heart Health includes ApoB, TSH, hsCRP, triglycerides, HDL, LDL, total cholesterol, and resting heart rate. So here are how my biomarkers changed over the 10 months - from Dec 2024 (before my 9- and 10-day water fasts) to Oct 2025 (after complete refeeding)

  • Heart Health: 76 (pre-fast) -> 54 (fast) -> 92 (refeeding)
  • Fitness: 87 -> 63 -> 85
  • Metabolism: 78 -> 65 -> 90
  • Inflammation: 84 -> 76 -> 95
  • Sleep: 81 -> 75 -> 84
  • Hormone Balance: 90 -> 81 -> 94
  • Cognition: 87 -> 78 -> 90
  • Gut Health: 93 -> 77 -> 94
  • Endurance: 86 -> 84 -> 86
  • Recovery: 94 -> 90 -> 98

And, in the chart, the black line shows Dec 2024, before my fasts, the red line marks the end of my last 10-day fast in Sep 2025, and the green line shows last month, after a month of refeeding. As you can see, the red line reflects how the body feels during extended fasting - not exactly thrilled, since fasting is a stressor.

Of course, this is N=1 data, and fasting (especially extended fasting) isn’t for everyone. But for me, it helped improve 8 out of 10 biomarker categories, so I just wanted to share my experience in case it’s helpful or interesting to others. If you did blood tests during extended fasts and after, please share your results.

4 days into a fast. Ran into trouble.

I was 4 days into a fast today and had to stop.

I was feeling cold all over and mentally slow. My girlfriend noticed it first when she walked into my apartment and immediately saw I wasn't looking well.

I was drinking my electrolytes. I take a half teaspoon of potassium citrate and 1 1/2 teaspoons of table salt and mix it into a brine what I take sips of. I drink a gallon of water every day and I take a magnesium pill.

My symptoms at day 4 were diarrhea, confusion, and I was so cold.

I've never fasted for more than 2 days before but what am I doing wrong?

This is my first extended fast.

hi, team. I've been fasting on and off for about a year, my longest prior to this was 70 hours. I'm currently at 87 hours with no set goal in mind. I initially thought I would do 48, but I felt fine so I kept going.

I am (f), 5,7', weigh 314 lbs, currently. I've lost 14 lbs since starting, I feel great, I can feel some pressure is off of my joints.

my questions are: being I'm heavier, I have more body fat to burn, is it normal to lose a lot of weight at once? how do you guys go about curbing cravings when you break your fast? what motivates you to change your eating habits? what are your go-to electrolytes? what are your favorite macro counting apps?

I'm a snacker, not much of a meal person as I work a lot and don't have time to sit so I'm constantly grabbing something and going. bad habit, I know. I don't feel hungry, but of course if I see or smell something, the craving is there. I'm trying to remain strong this time, it's been fairly easy.

any tips or tricks would be great!

I will also add, I was a pretty regular alcohol drinker so I'm sure that may play a factor.

Tips

I’ve been dealing with hyperinsulinemia and insulin resistance for over 2 years now, mainly because of overeating—especially late at night. I went from 75 kg to 110 kg, and honestly, I hate looking at my pictures now. I just feel really uncomfortable in my own body.

I’ve been trying to do a long 50-day water fast to lose all the weight, but because of the high insulin levels, my hunger and cravings are insanely strong. My mind gives in on day one every time. Then I try again the next day… and the same thing happens. It’s like a cycle I can’t break.

What’s frustrating is that 2 years ago, I was able to do multiple 5-day water fast without these intense impulses. Now it feels 10x harder

Also, for the past year, I’ve been feeling bloated and dealing with water retention every single day. I’ve honestly forgotten what it feels like to not feel bloated.

I really want to take this seriously and finally stick to it. Any tips, mindset advice, or quotes to help push through these cravings would mean a lot.

Best bread option for long term?

Hi all,

I'm asking this question here as I'm a big faster and currently on an extended water fast.

I fast for health and weight reasons, primarily in looking to remedy long-term health conditions (CFS, seb derm, insulin resistance, gut issues).

I know avoiding bread where possible in my circumstance is the best recommendation, but I'm also aligned with the idea that "the best diet is the one you can stick to". I have little concern once I break my fast surrounding avoiding junk or processed food, other than the fact I am a bread fiend.

if I can find one that agrees with me and causes the least amount of issues I feel I'll be in a very good place going forward.

I've heard people talk about sourdough, ezekiel etc, but I'm just looking to gauge opinions on what people think is the best option for someone trying to be more health conscious and less inflamed to give me the best chance of sticking to a plan and meeting my goals after I refeed.

I'm in the UK if that helps! thank you so much for any suggestions or guidance.

EDIT

Just as a caveat here, this bread would not be integrated anywhere close to my refeeding window! I have a plan for that already, and this'll be my fourth extended water fast

Help, I have insulin resistance, can fasting help me?

I've been dieting and exercising for a month and haven't lost a single kilo :(, I want to know if prolonged fasting can help me with this? Please share your experiences with me.

Fasting & ADHD meds

DAE here take meds & fast?

Docs: “eat lots of protein so they work”

Meds w/food: bogged down & sleepy (Even eggs, veggies, Greek yogurt, nuts). Exercise doesn’t help.

Meds also make me stupid hungry & only want bad food.

Fasting: no bad food cravings + increased & sustained focus & mood.

So, what gives?

Sorry in advance tmi

So I finished my first 52hr fast this morning . I wanted to do 72 but at 52hours I woke up at 3am super hot with 103 heart rate and felt awful. I ate 2 scrambled egg with a small amount of butter and after an hour went back to bed. (My plan was to eat keto after my fast to try and prolong some weight loss ). I feel back asleep and on waking this morning I ate one egg with 6 bacon, within 20 minutes I had onset bright yellow water diarrhoea on and off for about 49min , let’s say I didn’t make it to the toilet many times 😬. It stopped after this until I just ate dinner ( salmon , broccoli, green beans and peas in garlic butter) , same thing , 29 minutes after eating I’m popping my pants . I’ve googled and thought it might be bile but now I’m thinking it’s fast food transit ? Please someone help me out , what on earth is going on ? I’m more than willing to add carbs if it gets rid of this . Feeling fatigued and super embarrassed 🙈
