100 Hour Extended Fast - Recap and Lessons Learned

In this video, I take you through my 100 hour fast, discuss how I felt along the way, describe the benefits and share my lessons learned. Despite the "click-baity" thumbnail, this fast was about more than losing weight, as I'll talk about in the summary.

I'm pretty much on hour 96 of 120. This is my third time. Some tips: 1) Start it the day before. What I mean by that is if you can eat dinner early, say 4pm/3pm the day before you start, then by the time you wake at 7am you have already got a 15hr head start. 2) Plan it around days you can be lazy. The first two days, but especially the first can be rough for some people. So if you are like that, start it on a Sunday. For me, I like to plan it so I start on a day I'm working from home. That way I'm busy if I want to or I can look after myself a little more. 3) Water is your best friend. I don't know why but drinking from small cups isn't the same as huge 2lt glasses. When I feel a pang or acid, I drink 2ltrs. 4) Black coffee is your mistress. Feels like cheating, but isn't. 5) Exercise. I don't know the science but it seems like the body accepts that you are doing something and switches off the hunger nagging. 6) Electrolytes. There are plenty of sugar free, carb free, sports drinks with electrolytes. You never feel dizzy or swoony providing you have them in your system. I did a 20 mile run and drank a HEAP to keep myself safe. 7) Don't be beaten by cravings. Cravings and hunger aren't the same thing. You start imagining cooking and various meals. You don't feel hunger after day 3 but you promise yourself some food goal as a reward. Don't. Whenever you are ready to finish, push yourself that extra 24hrs. Why? Because you realise the hunger has gone and it's just the addiction.

I'm also on my 3-4th prolonged fast (4-7 days), I've just watched a presentation by Dr Berg that reminded me that ACV during a PF was a bad thing (too acidic), so won't be doing that again. Today, I'm feeling a bit achy (at just approaching 99 hours), but want to try to stretch the fast out to tomorrow morning and begin refeeding around 1000, so another 20 hours to go. I will review how I feel then. If I do begin to break the fast, it will be very gradual and following Dr Ekberg's guidance. I agree with everything you've mentioned and actually incorporate all of them already, so good advice, thanks. I generally follow OMEOD/OMAD, but get my best results for weight loss with PF. Thus, while I was hoping to get to 8 days fasting, if this icky feeling continues, it may have to be a 5 day fast. My protein meal will be some lamb chops and hard boiled eggs (after the refeeding process, which will take at least 36 hours). I try to get a longer prolonged fast in about every 3-4 months.

I love your channel. The longest fast that I've done was 146 hours...only black coffee and tea. I did it for the benefit of autophagy also. Love the feeling when fasting, plus truth be told...no meal preparation to think about! Keep up the good work!

[@SeriousKeto]

I'm working on a 132 hour fast, hopefully I can make the next 2 days.

[@w8ing4someday]

Wow amazing, and I was proud of hitting 48 hours. I am not sure I am at a point where I could even do 72 maybe in a couple months. I find it hardest during the second day, because I have a toddler that I have fix breakfast and lunch for :ol Dinner was easy my teenager was able to cook dinner. So I think next week I'll do my second 48 and if that goes well next month I may try my first 72. You look fantastic Steve, I teared up for you when you revealed your lowest weight and had to pause for breath. I'm with you buddy.

[@rjdn7932]

I fast 105-120hrs on a regular basis... I break a fast by simply having a cup of bone broth with a chunk of grass fed butter... then about 4 hrs later have my first "solid" meal. Makes it a lot easier on the bowels if you know what I mean

[@MrsSchnep]

Thank you for sharing this. I have just started a fast today and intend to do it until Friday night. I watched this for motivation & encouragement!

[@ctw594]

I got emotional watching you get emotional reflecting on the fact that you hadn't weighed 154 since college. I weighed 125-130 in college/grad school, have never seen it again. Did keto to get to 146 and I was so happy. Maintained for 6yrs but then put on 50 lbs in 2 yrs taking care of my Mom. Covid contributed a bit too. Finally restarted keto a month ago. Am feeling great. Lost 12 lbs - lost it faster yrs ago ;) You, headbanger's Kitchen and Keto Connect got me to restart and I'm so grateful. I'm in science and your approach and headbanger's (because of the flavors and cuisine) appeal to me the most. I love Clean Keto. The KetoConnect guys are awesome too. Thanks so much. Maybe one day I'll try a 72 hr fast!! Goals :)

I have learned more from listening to your videos than almost anyone I even subscribed which is pretty rare for me to do but I like your personal experiences and the fact that you're willing to share everything really impresses me and makes me come back to watch what's going on and what you're willing to share. I am really grateful to you for what you share and what you are teaching me. I like the keto twins also because like you are honest about their lives

Thank you.

Steve, congratulations on your fasting success and thank you for sharing the lessons learned. I really appreciate how real, honest and down-to-earth you are. Makes your videos very easy to watch. You are a natural on camera and, if you're using any type of notes or script, it's very hard to tell. Do you do the ACV tonic on a regular basis (when not fasting)? Thanks!

[@SeriousKeto]

No script, just lots of editing to make me not look like a total goofball. I do the ACV tonic pretty much daily (but with stevia when I'm not fasting).

Congrats! Such a great accomplishment! I did 78 hrs of them with you. Felt great, no problems here, other than a little weakness. I’m on maintenance, so I didn’t weigh, but I know the fasting helped me heal physically and spiritually.

[@SeriousKeto]

That's no small accomplishment, you should feel proud of making it that far.

[@ladye6907]

Just finished a 4 days water fast and I relate with everything you say. It seems like a Victory that the right word to describe it.

[@WiEar]

Great job, Steve! I am always following your videos as I find them to be very interesting and presented with the right kind of soberness. I decided to do a prolonged water fast this year, 2022, of 21 days, as I know that autophagy takes a long time to get you anywhere. My decision was not given in by a weight loss goal, but for medical reasons. However, when I got to the 21st day, I felt very good and had the distinct impression that the autophagy process had not been enough yet. So I went on, taking it day by day of prolonging it, until after the 30th day, I decided to go for 40 days. I am now on the 39th day, so tomorrow, the 1st of August 2022, I will end my water fast. I think I may have reached my goal, but will have to wait for the result of an MRI scan. Learned a lot as well!

[@SeriousKeto]

Wow! Very impressive.

[@user-sr8mf2vg9p]

Never fasted that long. I fast 48 hours every week. I struggle still with 48 hours and I’ve been at this for months. Btw, you look terrific. The loose skin is just a great reminder of how far you have come! Your grandson is adorable btw!

[@SeriousKeto]

I threw up one Halloween as a kid after eating hot dogs that night, and I couldn’t eat hot dogs for years afterwards, so I can relate to what you said about sardines.

Currently in my second 48 hour fast (hour 45) and I'm considering going 72 hours. My stats are: BG 68, Ketones 4.1 and GKI is 0.9. BP - 112/60 and I'm down 2 lbs. I'm within 10 lbs of my goal weight so I don't expect a ton of weight loss. It was great to watch this video and your 72 hour video. It gave me the desire to try the 72 hour. Wish me luck!

Great analogy with the Xmas eve. Congrats on the long fast.

The recalibration of tastes buds is so true. It's one of the reasons why I can taste so many flavors while sipping wine and whiskey. I did a 72 hour fast last October and one bottle in particular was night and day.

[@SeriousKeto]

I actually kicked of my weight loss journey the same way as Penn Jillette -- for two weeks, I only at plain baked potatoes. That not only recalibrates your taste buds, it also really teaches you to know the difference between appetite and hunger. You also learn very quickly that you don't really like potatoes -- you like all the yummy keto stuff you can put ON a potato. 😄

[@Sbannmarie]

I’m so curious if any of the folks doing “intermittent fasting” combine it with intentions with prayer. Powerful combo. Just wondered.

[@peterbarrett5496]

Reps for Jesus

[@AlteroCoach]

Well done! My congratulations! As for the skin issues it's very individual and in 100 hours there are not much time to expect any magic to happen. But if you do some fasting protocol like this one on a regular basis then I believe that you will see good results.

[@SeriousKeto]

I do 20/4 fasting most days. I know things will tighten up eventually -- you can't reverse 25 years of overweight in one week. 🙂

[@skylarbix7912]

@@SeriousKeto Congratulations on your 100hr fast! I just saw the video. As for loose skin, when you do 20:4, you can not eat any carbs, or just do 48's, as long as you have loose skin, there's no reason to eat food every day!

[@jeanthomas2272]

[@ohrick8707]

Steve - In a prolong fast, such as yours, if you had maintained your electrolytes-Salt-Potassium-Magnesium-Calcium-which athletes, bodybuilders... endurance athletes have learned to use in a fasted condition. This planks, may have been endurable! Athletes understand the benefits of Autophagy, but hesitate to lose gains, from not working out. You didn’t mention your water intake, or if you were dry-fasting. If you maintained hydration, throughout your fast, then I would recommend adding salt-Redmond Salt, is my favorite, and a growing commodity among the Keto, and Carnivore community. In a 3 to 4 day fast, such as yours... Water weight was your primary weight loss, especially if you weren’t adding a little salt to your water. Add to that, the complete emptying of your bowels. (The foaming sensation, was essentially “Light runs, as the elimination was completing.) Once the body is free from digestion, it begins the process of self-digestion. Like all waste products, it is eliminated through the bowels, urine, skin and breath. As for the lose skin hypothesis, it is “loosely” based on long term experiences in personal testers, and the visuals of (Sadly) those in long term concentration camps. Forced to eat OMAD-One Meal A Day... which is now a popular way to intermittent fast... 23/1 hours. Prisoners were forced into prolonged fasting/starvation. The body is very smart, and will utilize itself to survive. First removing the parts of cells, unneeded (Autophagy) then the lean body mass, adipose (body fat) and draw calcium from the skeletal system. And ultimately the skin. Some of those imprisoned, not very many, were overweight, and had loose skin as they were being systematically starved. The skin was self-consumed to survive... a little longer. The pictures of these tortured souls, still haunt us today! Sorry, to ramble off on this. But strategic fasting, more mimics the ancestral way of eating, that was no food for days, as you hunted for protein, and ate whatever leaves and berries found, to avoid starvation, along the way. They were a much physically healthier stock-like the lean animals they were-than we are today... not counting for disease and lack of trauma care, when the beast you wanted to eat, fought back! Or found you first! Personally, I’ve gone full “Nose to tail” Carnivore after prolonged Keto. I have added back onions garlic, cilantro... a few LC items (Chaffle’s) so I’ve settled down to a 90% carnivore with 10% LC. (Down over a 100 lbs.) You’d be surprised, how much easier meal-planning is, when you focus on fatty-meats. And not always the duplication of the foods that got you sick/heavy, in the first place. Congratulation on that 70lbs. Great accomplishment... you are not going backwards. And, thank you, for sharing your knowledge and experience.

[@SeriousKeto]

I was using Sports Salts, but perhaps not enough.

[@ohrick8707]

Serious Keto - There are newer combined supplemental electrolyte solutions out there. However, I add all but calcium, in supplemental form, as a daily insurance policy. (Not familiar with yours) Almost everyone is already deficient in D3, potassium and magnesium, which can effect blood pressure and cardio electric function... arrhythmia/ A-Fib... If you are living a Keto-lifestyle or a Carnivore one... salt becomes more important, due to the enormous amounts of salt consumed in processed food! When you remove that from your life style, the addition of “Healthier salts” becomes something you need to be aware of. WE die without salt, and it has been made a villain, by most cardiologist. You need to compensate for eating healthier, by being aware of your electrolytes. Consider 10,000 IU’s of D3, and add 400 Mcg of K2... they work together in the transport of calcium to the right places, instead of your arteries. I’m not a medical professional-pre-med, and battlefield trauma patching doesn’t count. However, as many of us do... late in life, and after the fact... I’m well read, and have enough personal mileage and measured results, to narrow down many of these things... I wish I knew in my younger adult days! 🤷🏻‍♂️. I did a 10 day fast once... didn’t hydrate enough, and was depleted of electrolytes... I nearly passed out. Started eating immediately... back in the game... learned at the very least, hydrate more than you think, and add quality salt along the way. I salt my coffee, anyway, because a local roaster said “Do you salt your food to bring out flavor? Coffee is a food.” 👌

Broccoli and cabbage where the problems. Thomas Delauer says don't break a fast with fat and carbs together, one or the other. Spiking your insulin will automatically store the fat and breakdown the carbs. I break my fast with carnivore diet.

100 hours now. Feeling great. Pain (reason for extended fasting) almost gone. I started withe idea doing three days (72 hrs). Think it wil be 5. 💪

[@SeriousKeto]

The last one I did was 150 hours, I think. It's wild how great I felt (once I got my electrolytes dialed in). Good luck!

[@YeshuaKingMessiah]

Fasted 90 hrs as my longest. Lost zero. I dont fast for wgt loss tho. Its to help with my IR which will result in loss at some point. Fasting is to HEAL. IF heals daily. Dry fasting is much shorter and more healing. My fav. Absolutely kills hunger.

[@SeriousKeto]

I've heard that about dry fasting and may do that for my next fast. What do you recommend as a minimum and maximum number of hours for a dry fast?

[@brucewallace2]

Well done my friend!! I think I'll try this fast idea.

[@SeriousKeto]

Have you fasted before? If not, I'd gradually ramp up. There are a lot of good tips from more experienced fasters on the videos I've done chronicling my fasts.

[@brucewallace2]

@@SeriousKetoWell I'm a Type 1 diabetic and so must tread carefully as it will mean adjusting my insulin. So I won't be jumping into a 100 hour fast as that's 4 days effectively. When I was in my 20's I was badly overweight and ate an apple and a small piece of cheese for 6 months. That is about as close to a fast as you can get. I'm 63 now so need to be a bit more careful. p.s. love your videos.

[@CuttoothsRoom]

Congratulations on the successful fast and results. The next time you video document your next fast I’ll try to muster up the motivation to follow along. The thought is definitely daunting. One other question that you may have answered in another video... What is your exercise routine/calorie burning goals while doing your regular daily dieting? Maybe you can put this info up as a rough guideline for people on your website?

[@SeriousKeto]

3-4 days a week, I will do a series of sprints (20 second sprints, 10 seconds walking) for 5 minutes (plus a 1 minute warm-up and 1 minute warm down). Then I walk for 30-60 minutes. Aside from that, I work my abs 4-5 days per week and have been working my way through the 30 day plank challenge. I'll probably get back to lifting weights next week. Honestly, I'm trying to stay away from giving any health or fitness advice, as I feel I'm grossly unqualified to do so -- and there are many better resources for that on KZbin.

[@CuttoothsRoom]

Thanks for replying with those, I understand what you mean. I’ve watched a lot of different channels and think it’s helpful for me to get different perspectives. That way I can figure out a routine that I think would work for me and that I’d be comfortable committing too. As always, keep up the good work with the videos 🤙

[@SeriousKeto]

Another project of mine, after SeriousKeto is running comfortably is called LeanBodyMind. I already own the URL and trademark. It will about improving health (agnostic of diet type), mental and emotional well-being, and personal productivity/creativity, leveraging various tools and methods that I used for years practicing and teaching Lean / Process Excellence / Continuous Improvement. That's a 2020 project though...

[@Britonbear]

That's an interesting idea regarding trying to train your taste buds. I've been hamstrung by my dislike of cauliflower/broccoli/cabbage. I haven't done a longer fast yet, I am doing OMAD, but when I do I will try that theory out.

[@SeriousKeto]

I was watching one of Heston Blumenthal's shows on BBC and he had a young chef who workd for him that hated some ingredient that was part of their menu. He said that if the young chef ate it 28 days in a row, he would learn to like it. He was correct. Still, I'm not sure I could do sardines or Brussels sprouts 28 days in a row. 😲

[@Britonbear]

@@SeriousKeto You'd think that would put you off for life! I don't mind sardines but I prefer tinned mackerel. Could eat that every day.

[@FlawlessCFO]

Good job. Great results.. I'm thinking bone broth the first 12 hrs would have eased you back into eating

[@georgina8960]

What if you did carnivor after the 100 hour fast ..should be imposs to put it back .maybe pork ribs w fat and a keto bbq rub ..and a steak and 2 half roasted tomatoe s provençal .that's with slivers of garlic drizzled ovo and italien seasoning underneath the garlic. .and small amount of parmesan on top ..yum with steak with herb garlic butter ..amazing weight loss Steve way to go .

If it helps with the skin issue then I would for sure do it. It's part of the reason I can't reach my goal weight. It's the skin! Argh! Congratulations on your success and thank you for the information!

It's one of those "hindsight is 20/20" deals. It didn't occur to me until after the fast that I should have gotten a pair of skin fold calipers. Oh well, we'll get it next time.

[@ybe7011]

@@SeriousKeto you're doing great! We're all in this together. Someone just brought up that study just published about red meat /keto being the leading cause of mortality. I just laugh. People believe what they want, don't have the facts and feel good to preach to you how unhealthy this diet is when you look and feel fantastic, then they go through the drive-through! Okay 👍!

[@SeriousKeto]

My attitude is that we must each figure out what works for ourselves. You'll notice that I don't try to convince anyone that keto is the only way to go. Too many people try to push their dietary beliefs on others and get more worked up about it than religion or politics. I just relate what has and hasn't worked for me and let people do what they want with that info.🙂

[@cayce9320]

Steve...did you do any special kind of prep for the fast? If so, what? I did a 48-hr fast recently, sort of on a whim. The diarrhea I experienced most fast days and ~ 4 days beyond after I ate again were pretty unpleasant. I added more electrolytes than is my usual daily amounts and suffered a lot at night with leg/foot cramps. ( I am very prone to this anyhow, so I think it was exacerbated by the fast.) Anyhow, I want to do another extended fast soo, but think I need to have some sort of prep. Any advice you can offer would be most helpful.

I’ve read differing opinions on that. My opinion (I’m not calling it a fact) is that if it has calories, I’m not going to consume it during a fast.

[@riaxhigne7645]

@@SeriousKeto thank u so much.

[@ilbsli]

i’m trying to figure out how many days of fasting is 100 hours, so let’s say the last meal you had is 4 PM on Saturday then you would break fast on 8 PM Wednesday right? so that would be around four days of fasting!

[@SeriousKeto]

Four days and 4 hours. I started mine Sunday at noon and ended at 4pm on Thursday.

[@ilbsli]

Serious Keto just to make sure I’m getting this right so on Sunday you had your last meal before the fast?

[@SeriousKeto]

I took my last bite of food around 11:45am on Sunday. The next calorie I consumed was on Thursday at 4pm.

[@keithl6249]

Thanks for the information. Are you at your goal weight now? I think you said you have lost over 70 lbs? Congrats! I have about another 50 lbs to lose. I'm on OMAD , keto most days. I am considering longer fasts, mainly to see if it helps me with my snacking habit, OMAD has helped of course.

[@SeriousKeto]

I'd like to hit 153.3 for just one day, as that would be 2/3rds of my starting weight. It's just a bell I want to ring. After that, I'll be upping my calories and rearranging my macros to support some strength training / muscle building and see what kind of transformation I can achieve by next summer.

[@RedBearAK]

I know you do electrolyte tablets but I think it’s very easy to underestimate how rapidly minerals are excreted on an extended fast, even more so than on strict keto. I believe that is the primary source of the muscle fatigue during fasting. Try increasing those electrolytes next time.

[@SeriousKeto]

Will do. I had bought some electrolyte packets that dissolve in water from Costco. It wasn't until I got home that I saw they had 18g carbs (or something like that).

[@trudygrabowiecki5374]

I noticed you mentioned you are on blood pressure meds and so am I. The last time I did a fast was for 24 hours and my blood pressure dipped to 105/68 and I was extremely dizzy. I have been afraid to fast since then. Have you ever experienced this?

[@SeriousKeto]

My first extended fast, I actually saw my blood pressure go UP. I think it was my body being in a bit of panic state from lack of food. I have not had it dip especially low during a fast. Today, 6 days after the fast, I'm hanging out at 108/72. I'll go back to the doc in a couple of weeks if it's still there and will probably dial back to just a once daily dose of Lisinopril and then hopefully be off meds all together.

Great job / great video. Question... how do you clean your Mini when you’ve had a spill? I’ve had a “corn desilking brush” lying around for years, and finally found a use for it. Cleaning the Dash

[@SeriousKeto]

I found a set of (I believe) nylon bristled soft scrub brushes on Amazon that work marvelously. If the pill gets into the seam between the griddle and the body, I"ll using a paring knife to clean that out. Otherwise, I just run the brush under hot water and use that on the Dash as I hold it sideways above the sink. I don't use any soap. Hopefully that description makes sense. I may make a really short video out of it, because it's a common question.

[@masdmedicalalertservicedog9466]

David D I use a soft toothbrush.

[@darlin1951]

A silicone spatula/basting tool works great for cleaning waffle irons and no danger of melting bristles.

I don't clean mine when it's hot, so not a worry there.
