- Intermittent Fasting vs. Prolonged Fasting: Benefits of 1-3 Day Fasts- Thomas DeLauer… Learn some of my Fasting Protocols with me 1:1 www.ThomasDeLauer.com
Prolonged fasting (PF) is that which lasts from 48 hours to 120 hours-
Studies have found that fasting:
Reduces oxidative damage and inflammation
Promotes optimal energy metabolism
Protects cells
In humans benefits include:
Weight loss
Arthritis benefits
Asthma improvement
Helps with hypertension
Prolonged fasting has been demonstrated to:
Increase cellular resistance to toxins in both human and mice studies
Reduces circulating insulin-like growth factor 1 (IGF-1)
Protect cells from chemotoxicity (for example those who undergo chemotherapy)
Differences between PF and fasting of less than 24 hours are likely due to the complete exhaustion of glycogen. Our liver stores most of our body’s glucose in the form of glycogen.
Following 12 o 24 hours of fasting (varies by person and factors such as physical fitness), liver (hepatic) glycogen stores are depleted and the body turns to the following for energy:
Nonhepatic glycogen stores
Free fatty acids
Ketone bodies
Humans can survive 30 or more days fasting. This way of producing energy may slow cellular aging in mammals. It is natural for humans to have high energy when hungry and lower energy when satiated - likely because we would have needed our brains functioning well to come up with new sources of food.
Hunger creates a cascade of bodily processes that may explain the benefits of fasting. When we are hungry, certain hormones are released and neuronal networks activated. The hunger response leads to increased activity in the neuronal networks related to cognition.
This leads to:
Production of BDNF (brain-derived neurotrophic factor)
Synaptic plasticity improvement
Stress tolerance increase
Cardiovascular benefits are likely due to the increased levels of adiponectin during fasting
Adiponectin is released from fat cells. Obese individuals have less circulating adiponectin than normal weight individuals. Too little adiponectin is tied to many chronic diseases, including type-2 diabetes, metabolic syndrome, non-alcoholic fatty liver disease, cancer and heart disease. Adiponectin in an anti-inflammatory agent and protects against chronic disease. Hypertension has been helped in a human study with 13 days of water only fasting, and the benefits even remained when blood pressure was tested following 6 days of normal eating. Fasting for 3 or more days leads to changes in insulin, IGF-1, IGFBP-1 and glucose:
30% or greater decrease in plasma insulin and glucose levels
Decrease in IGF-1, the major growth factor in humans
High IGF-1 and insulin levels are tied to aging and cancer
Increase in IGFBP-1 (a protein that inhibits IGF-1)
Longer fasting periods have shown impressive results for those with rheumatoid arthritis
Best results are with a fasting periods of 1-3 weeks followed by a vegetarian diet.
Immune system benefit:
Fasting for 3 days or longer leads to a reset of the immune system
Fasting lowers white blood cell counts, leading to new white blood cells being created by the immune system
A study took cancer patients who were undergoing chemotherapy and had them fast for 1, 2 or 3 days prior to chemotherapy.
Those who fasted for 3 days, but not those who fasted for 1 day, experienced fewer harmful side effects, such as immunosuppression .Many positive effects have been found for both prolonged fasting as well as intermittent fasting, so incorporating either into your routine will likely be beneficial.
*It is very important to speak with your doctor before going on a fast lasting 3 or more days. Longer fasts may not be advised for those who are underweight, young or old.

I water fasted for 6 days ( no food at all for 6 days in a row) and never felt better, clearer in my life. I climbed the local mountain twice that week. I was depressed and it went away.
Mireille will it result in muscle loss!?
A little bit the first 3 days till ketosis kicks in properly. But you will gain the muscle back fast when you go back to your "gym". You can not lift weights or do HIIT during long fasting. (7+ days) The real benefits come from 7+ days of fasting.
If HGH goes up so will IGF1, does it matter if HGH+IGF1 is created 'naturally' via fasting/exercise compared to eating dairy/red meat/soy isolate protein etc, do you see my point?
If one has a pre-cancerous condition and one wants to avoid upping growth hormones, its simple - avoid eating foods that increase it, but I wonder would fasting/exercise cause the same kind of risk seeing as HGH+IGF1 are increased when fasting and exercising, thankyou.
Mireille I'm at 40 hours of fasting, and I feel kind of weak and spaced out a bit. Did you experience any of that at all during first few days?
HGH goes up, IGF-1 does not...
I did a 7 day fast years ago and I can attest by day 5....your energy is through the roof! It's crazy! I felt led by God to fast that year before the IF craze.....and I ran a milk route, which is very brutal work, but I never felt better in my life. Fasting is a gift from God if you give it a chance! Even Jesus fasted 40 days so if it's good enough for Him....it should be good enough for us.
A gift from God. I love that. It does feel that way. I went three days last week and felt more present than I had since I was a child. Looking forward to starting another three days right now.
I was seeing Satan by Day 6, man.
Stop looking at the mirror :-)@@baconatorrodriguez4651
They say you can talk to God more with fasting because you're giving up something that is very meaningful to humans and that's eating. But when you fast for long periods of time you're basically sacrificing something you love in order to get closer to God
Here I am fasting for close to 24 hours and was ready to eat. This is the message I needed to hear. I’ve reset and I’m ready for the next 48 hours ! Let’s goooo #GodIsGreat
Thank you for debunking the if-you-go-5-minutes-without-food-you-lose-muscle-and-passout myth. :-)
Fasting is amazing for the body and mind.
wait what ? ever heard about autophagy ? While not eating, your body will use what he cans. Fat as fuel, muscle as amino acids. that's what happens everyday to everyone, but then you eat, build some new muscle fiber etc etc so you don't really lose anything. The real problem is : Heart is a muscle.
Serious studies, not talking about pro-fasting studies, nor cons-fasting studies, will let you know that most of the deaths since 2010 while fasting are due to heart weaknesses. And yes, every years, some people die while doing a prolonged fasting. Another side effect you won't read in pro-fasting studies. (im talking here about 20 days + fastings).
Im not against nutrition gurus, but people should be able to know that for every benefits, there are side effects. always.
Kendall A - this is only true if you combine fasting with exercise. Exercise while fasting helps produce human growth hormone and gets you in ketosis.
But also ups igf1
John Vinceace Of couse if a person with bad nutrition, and that is used to eat all day long and they try a long fast they're gonna colapse,you have to let your body adapt at your own speed rate and then enjoy the amazing benefits!
Yup and fhuck what mainstream consent "recommends"
Day 1 fine day 2 wanted to eat everything day 3 no cravings day 4 no appetite at all felt like I'd never need to eat again 😂 did 8 days felt fantastic after
Im on day 14 doing 21 water only not even hungry
Haha holy shit y’all
@@steveotatooed WOW 👏
Just wow and how?! Lol
Any supplements during ?
I love fasting. Prolonged fasts are great. I intermittent fast on a daily basis all the time anyway but you truly unlock massive health benefits when you prolong your fast. And yes, everyone you know will tell you that you are crazy but it's only because most people lack simple willpower when it comes to getting out of their comfort zone.
Listen... The inbred desire to eat frequently is powerful...and like everything great in life it takes discipline and willpower to trap the benefits of fasting...I'd bet most Americans have never even went one day without eating
Absolutely correct.
curious, how often do you do a prolong fast?
@@toddholmes1487 Twice a year. 7 day minimum.
I did a fast a couple weeks ago for the first time, 7 days total, dropped about 14 lbs. I'm on day 4 of another fast right now, it's actually pretty easy. The biggest thing I've learned is that eating before never really had anything to do with hunger or needing energy (at least not for me at 250 lbs, BMI 36), my body had all the fuel it needed stored in my fat gut. Eating was just something to do and was pleasurable and satisfying, like any other activity you do for fun. It's changed my notion of my own capabilities and will-power.
I'm on 60 hours right now of no food just water...shooting for 5-7 days
steven bulback how ya feeling?
Holla if ya hear me I completed 5 days.. day one was weird going to bed with no food but felt good.. day two I felt great but had a minor headache so I drank a cup of beef broth to up my sodium.. got rid of headache. day 3 I felt amazing but was home from work all day because of rain so I was bored and when you are bored you eat so it was a will power challenge. day 4 was fine I wasnt hungry I just wanted to crunch on something out of habit... day 5 I broke my fast in the evening with fruit.. then ate seafood later on as well. I lost 12 pounds but I'm sure most of it was water weight but I will sry my pants fit a little more loose.. I took a break over this weekend because my fiance wants to start Monday so I told her id do it with her again
how much of the weight did you gain back post fast, over how long?
Axel47 so far like 3 pounds and it's been a few days over a week
steven bulback
no bcaa?
I've been intermittent fasting for years but I did my first 72 hour strictly water only fast in August 2018. I just did a 48 hour strictly water only fast 2 days ago (October 15, 2018). I love it! I save time, money and don't have to think about food which allows me to focus on life. Plus I have more energy. Fasting is a massive life hack that more and more open minded and optimum health seeking people are discovering. Thanks for all of your videos Thomas!
I agree my first 3 day dry fast was amazing. I had lots of energy and didn't have to think about food and got a BUNCH of work done. I would like to do a 3 or 5 at the end of every month. Would that be safe?
No safe. Long term fasting strips away the muscle in the heart.
@@William14094 that's what I'm worried about. all these people seem to claim they just go for days with only water and no nutrition, that sounds dangerous...
I did not think I would easily break the 18 hour fasting barrier but I did. After seeing this video, this morning, I decided to have a go at beating the 36 hour record. I am not yet hungry!
Awesome! This info has been life changing for me! Before understanding all these benefits was all about weight loss, but now it’s more motivating because of all the benefits!
The body gets used to it.
I wanted to try but I got an insanse headache and just had to eat but I’m going to go at it again for atleast 35 hours
You drink water I assume?
What helped me was go to a 5 star hotel and have a massive breakfast buffet as my last meal before a 10 day fast, the quality of food is really good and it doesnt cost that much, the buffet has a variety of foods - you got fats carbs juices proteins there is everything to set you up for your fast. I wasn't hungry and didn't experience the usual headaches I got from fasting before. Then when I got headaches after 48 hours I started taking coffee and mixing 1/2 a teaspoon of salt per litre of water.
I started fasting three years ago. I did as part of my worship to the Lord. I lost weight and I trained as well. I was amazed how good I felt. Just remember work up to three days. I started breakfast to dinner, then 24 hours, then 48 and finally 72 hours. The benefits were amazing, long term I started eating less overall. This works. The first time is tough, because your stomach will growl. You can do it. Praise God. Working out and no eating is amazing!! The fat will just melt off, but drink lots of water
Ruben Trigueros. Thanks Ruben. I'm gonna try this.
Ruben Trigueros Yes always drink water will fasting! I started with IF at 12 to 24 hrs for 1 year! Now working on getting to 72 hrs!
Ruben Trigueros what foods were you eating while you were working down to fasting?
Nomee. I ate vegetables when I started and ended, although I did eat eggs before and after the fast. Also avocados, nuts, salad, carbanzo beans. And mostly raw. Except the eggs. A lot of Mexican ( avocado, tomatoes, onion, cilantro and chiles mixed and raw. Yum!!
Ruben Trigueros oh okay thanks
I’m on 94 hours open fasting my only goal is 72 hours but after I reached my goal I’m feeling fantastic that’s why I decided to continue fasting till I can’t.
i reached my 48 he goal and felt good so i decided to go to 72 and feel good so now i’m coming up on 72 hours. think i will push it out to 94 too. i do drink my minerals daily Mag, pott, sodium mixed in 16 oz water in addition to essentia water and plain water , black coffee , green tea, black tea.
I'm 41 hours in and have just come back from swimming half a mile at the pool. I'm going to go out for a walk in a bit. I started at 220 lbs. I hope to lose 10-12 lbs. If I feel ok I'll keep going it would be great to get down to 200 lbs we shall see🙂👍

You are amazing man.....Fasting is the ultimate cure for every illness out there
great info man. i started my prolonged fast 99 years ago. now i am commenting from heaven.

that would be great thumb workout :-P
it may actually be true if you do it for religious reasons lol

I completed a four day fast and looking back I am disappointed that I broke it because I was not in the least hungry. I was so alert and full of energy and confidence. I felt like a new creation. I am going to start again today and I will place no time limit.
Hi there! I know it was more than a year ago, but do you remember how many days you ended up fasting? And have you been doing it again and again? Greetings!
How did it go? Asking two years later.
@@Peter-ri9ie : Having never been to any doctor I would say so far so good. I still eat once a day. Not religiously but intentionally.
i did 3 days fast and it changed completely my mood i have so much energy now ,and so happy
I was 380lbs in 2015 and fasted for 4 days in an act of desperation but suprisingly felt really freakin awesome. I started to implement Keto diet and Prolonged fasting M-W and then Keto the rest of the week and now I'm 275. Fuck what other people say if it works for you it works.... everyone is different and I just happen to perform better and live a higher quality of life when Im fasting.
Great Vid!
fuck those retards
I’m 73 hours in my fast now. Have done two 7 mile runs and 1 strength training session and feel amazing. Going for as long as it feels good. Have a 12 mile run tomorrow so we will see. Thanks for all your great videos Thomas 🙏 Greetings from Denmark ☺️
This is bollocks
Dr Ekberg disagrees. You're supposed to do light aerobic exercise like walking or do HIIT.
Too much stress will increase your cortisol which will increase insulin and blood sugar to feed your poor muscles!
You might start breaking down your muscle protein to create glucose to feed your muscles...
can you please share what you took/drank during those days other than water? did you take vitamins? protein? thanks!
@@arthedainedain9846 Have you even tried fasting? I'm guessing not
@@freddyfox5002 84 hours so far... That's how I know what he writes is pure bollocks
I’ve officially hit 36 hours fasted and I’m trying to decide whether I should keep going. I’ve never fasted past 24 hrs. I think I’ll give it a try!
good 4 you !! ❤ I'm going for 48 1st time
Try 5 days!! It’s awesome-
Of course, check with your doctor first. 🙏
I’m so grateful....I’ve been doing 16/8 hours fasts for about 3 months and know I’ve been doing a 20 hour fast twice a week and it’s been wonders.....i finally tried a 36 hour fast and felt so good and accomplished.....I feel better stronger and more aware of everything in general......wish I would’ve known about fasting way sooner!
The energy focused thing is exactly what I have been preaching to people about for months! This is awesome!
I just got done with a 96 hour fast! Thanks for all the amazing information, I have been doing IF for 6 years everyday.. so I'm well educated on IF, but PF is an entire new level. Thanks again!
Thank you, Thomas! I did an 86 hour water fast at the summer solstice and now with Winter solstice upon us I want to do another extended fast! I’ve been intermittent fasting and doing some extended fast since then, with really good results but I want to go for the really long one! This video is one I’m adding to my arsenal! Because I’ve watched all the other ones in my playlist, lots and lots of times but this short video helps me commit to the long fast that I need to do! God bless you and your family! Stay blessed
MY story. I went to bed Sunday night after eating a pizza, big bag of chips, 6 pack of beer and a couple cocktails. Woke up Monday at 7. Fell back asleep. Got back up at 11 and had to cancel work. Felt so horrible I decided to stop everything and go on a fast. I had done one 10 years ago for 3 days and knew I'd feel great after a couple days. I stayed on for 128 hours till Saturday morning. I went from 155lbs to 144.2lbs. I did moderate exercise for an hour as much as my body would handle. TRUTH- this time I felt out of it till Friday. It's now saturday morning as I type and I'm drinking coffee and going to eat in about an hour. I feel like a new man...Fasting works- even if you dont do it right- it's the hardest "easy" thing you'll ever do.
This video brings me back to 4 months 45 lbs ago. 230 to 185. I ultimately chose IF 20/4 and haven't looked back. I'm 41 and in the best shape of my life. Thanks
Same here. 20/4 it is! Look great, feel great.
Mutha fuckin G! Soooo much knowledge bein kicked! I get what you’re saying as I’ve been experimenting w/ 3-5 day fasts recently and am 100% committed to a 3 day fast every month from now until I expire. Major, major profound life breakthrough, awakening, straight I see the light type of transformation. I didn’t care about the weight loss, I needed a gut reset, I had no clue I’d get a spiritual revival and I finally kicked my excess sugar habit! Preciate you my dude!
We’ve told by society “3 meals a day” or “you just gotta eat something”
The arguments for fasting make complete sense, will be stating to do it, it sounds exciting !
Thank you for your videos. I'm learning so much. I'm on my third set of fasting for three days. I wasn't for sure I could handle the headaches. I drank water and one 6 oz cup of coffee in the morning. Switch to green tea. Stuck with no calorie, no carb. I was sick with a bronchitis type flu so I wanted to keep the warm drinks and liquids coming in. I had a headache off and on. Lost 6 lbs. Ate keto type meals in a small window. The second set of three I did the same but added apple cider vinegar with some liquid magnesium. I was getting muscle spasms. Got through the third day. Dropped 7 lbs. Came off and ate egg souffe or keto quiche. Added one piece of bacon. OH BIG mistake. Not so much the soft eggs but the one piece of bacon. Had a large salad with avocado and lots of good stuff. My stomach suffered most of the night. So....this morning I started another three day. I just couldn't do the black coffee. Sticking with water and apple cider vinager. I'm assuming that the body will still get the same benifits fasting 3 days with acv and non calories, non carbs as just plain water. (?) I saw your video on coming off a three day fast with the bone broth frothy drink. Looks good and thanks for sharing the recipe. I had no idea that cream of tarter has benefits of potassium. You have been a great encouragement to me. Blessings
I just started prolong, 72hr fasts, every week. Instead of interment, Its healthier to just combined the intermittent days. It’s controlled my hunger and volume of food control so much. It also feels nice, and frees up time. Not saying it does not feel weird to not eat for 3 days, but once you learn you won’t die your set. Lmao
I've been doing this also. Every week Mondays to Thursdays. I've been losing weight and never felt healthier. Plus on my eating days I actually eat food I generally fear eating, but still eat as healthy as I can.
How many calories would you eat on a feed day ?
@@lisajay4394 that’s so true. After 72 hours of fasting I would eat whatever I normally would not really feel comfortable to eat. I have found this powerful way to enjoy food more on the day I don’t fast.
I am just over 48 hours at this moment I’m writing this comment. Plan to go to 72 hours and might be even more if I can. It will be my first 96 hours.
Wish me good luck :)
That's what I'm planning on doing im 12 hours without food rn plan to do 72 hours
Didn’t he say that prolonged fasting should only be done once annually?
Hey Thomas, im 50 years old and trying intermittent fasting for the first. I'ts been 2 months now and I have noticed a huge change in my body. Thank you for putting out your videos and motivating me to stay fit....
What were the changes?
Just completed a 48 hour Fast. It was really enjoyable, even though there was enormous outside stresses upon me; I felt focused and calm during an emergency situation. I am glad I was fasted for this testing time. :)
yutu34 Same! Isn't it annoying how every single prick around you will try to get you to break and eat something?
Flamewerkz fuckEM
You are such a brilliant man Thomas. Thank you! I really appreciate how much you share all your knowledge with us, it's always so helpful. I'm sure many would agree.
I am on day three of fasting! Day one was difficult, day two was a little better but day three I have no appetite whatsoever. I have a lot of energy, feel so good and have more confidence! It's kind of amazing. Just drinking LOTS of water!! Hoping to go for 6 maybe 10 days :)
I am thankful to have lost 140 lbs since May 2021 using keto/IF/and PF (5-7 days ). The benefits of health and feeling of well-being are fantastic. 45 lbs to go! I have tried other strategies (variations of plain old calorie restriction) in the past, and found those strategies to be a tightrope I just couldn't stay on long-term. I gained all the weight back each time once life stresses got bad and I inevitably crashed and burned. But with this plan, life stresses that have occurred or been present during this time (grief over loss of child, illnesses in family, etc.) have not knocked me off that path, but in fact have kept me more firmly on it.
I learned to be able to tell when I'm in a ketogenic state without testing my ketones. There's a hint of euphoria that's associated with such an increase in ketone concentration. It goes away because I get used to it, but it's rather motivating for me to get to that point. It's wonderful. When I tested my one-rep-max before and just before re-feeding after 5 days, it didn't change all that much. In fact my strength to weight ratio increased dramatically.
Great vid, thanks for sharing
Lou Arnold - UA-camr Cristã so beautiful
I’m on a 37 hour fast and I feel like crying 😢
Me too, I'm doing the 72 hour, my goodness I can't wait till this experience is over, lol.
Make sure to drink PLENTY of water. You will feel like crap if you dont drink enough water to stay hydrated. You will get headaches muscle cramps and stomach discomfort if you dont fill up on water. Its essential to the whole fasting thing. I'm on day 3 and never felt better
Take a vitamin supplement beforehand or consult a doctor because you should not feel awful after 37
Then stop lol
Thank you
Great info. On hour 22 and trying for 72! Going great so far.
Just found your videos. Well done. Good mixture of practical with scientific back up. Your videos are above average with the information given out below the video too. Very timely for me, since I'm trying out 3 1/2 day fasts using the Tim Ferris method ie supplementing w/ MCT and long walks.
Very knowledgeable on the subject of fasting - I much appreciate what your doing for those of us desiring to heal and live a more productive life. God Bless You!
Completed a 21 day fast last October, first 3 days were rough however my energy shot up, I felt super good and lost 18 pounds. Currently in day 3 of a 30 fast. Stoked it’s not food I miss. It’s the ritual. The habit. Give me a couple more days and that’ll disappear too
Finished a 72 hour water fast yesterday. I felt fantastic today.
This guy is always putting out great informative content . Salute u Thomas
I thank you so much for putting references into the description!
Dr. Jason Fung explains everything about fasting
so packed with value! awesome video man! I do IF but not often Prolonged. I'm gonna try this out.
btw I can help get better rankings on your videos reach out man i'd be happy to have a chat with you you deserve more attention
I'm on my second Soft Dry Fast this month. First try was 4 days...5 kilos lost.
This time 7 days...on the second day!
I LOVE THIS!!!
Hai bro how is the progress (18 hours im not eat anything)
I've been doing two 24 hour fast per week almost three years now. I'm doing my first 72 hour now. Great video and info, thanks
I'm currently on a 2 day (what what will end up 56 hr fast), at hour 35-36. I feel an increase in focus for sure. Just have been drinking plenty of water, haven't been working out more than a few chin-ups/press-ups, I think I drink about 1.2 imperial gallons/5 litres of water a day to make sure I'm hydrated as I won't get any liquids from any other source. I want to extend it to three days now! If you're thinking of starting this for the first time like I am, good luck, keep focused, don't give in to your cravings and you'll be a healthier, stronger willed person because of it.
42 hours right now! My house is looking pretty good too. So much extra energy.
Hey Thomas Delauer I have been intermittent fasting for about a month now coupled with the keito diet. I fast for 25 to 26 hours a day, and I feel great ! Ive seen my body change allot since ive started gyming and also following your advice. I have also started training in a fasted state and it feels good. I do make sure to eat enough healthy fats in my feasting period and lets not forget steamed vegetables and allot of salads.
You didn't mention the financial benefit of prolonged fasting..
I did an 18 day water fast a couple years ago on one of my holidays. Protip, don't do a water fast that lasts more than a few days in the winter. Oh my sweet mother of jesus... that was brutal.. particularly as it was below zero almost every day and I still had to go outside several times a day to walk my dog.
And my dog wasn't fasting, he had no problem running wild in the snow and cold and he needs his exercise every single painful freezing agonizing day.
So yeah, do water fasts in the spring or summer.
:P
Great videos. Keeping it scientific is the way to go.
I see a lot of comments asking for dos and don't. Perhaps a video on that?
Btw your stock footage is hilarious bad, and frankly rather distracting for getting the message across.
Best fasting vid seen to date.
No bs straight to point!
Just finished my 3-day fast. It was an intense but energizing and exhilerating experience.
I like this no BS channel !
this reminds me, I need to go check the mail...
good video! Lots of great information.
You were made for UA-cam instructional-training. I love your channel.
I had never fasted before, and started just by doing a 120 Hour PF. It was surprising how many results I saw, I lost almost 20 pounds(I weigh about 270) , but I didn’t continue the fast and I regret that because I gained it back. If you’re interested in doing this I would definitely try it, but with the idea in mind that it will be a lifestyle thing.
Your stock footage skillz are insane!
I did my first fast for two days this week. First fast ever. I wanted to see and feel what how my body would respond to both hunger and being in ketosis. I thought it would be difficult- but it really wasn't. The first day was a little hungry throughout the day with highs and lows- but the second day was much easier. I also made sure that I wasn't just sitting in a chair thinking about food. I put my raycons in, listened to some music and cleaned my kitchen, went on a ride on my one wheel, etc. I felt perfectly fine. This is something I'm definitely going to incorporate into my weeks. No more trying to figure out what I need to meal plan for the week- how much veggies I need to juice, etc.
I love that your videos have big description text.
Great Information. i intermittent fasted from the day after Thanksgiving, where I weighed 233 lbs. until this past Tuesday. I had 1 meal a day for that time period and my weight went down to 220 lbs. Then on Tuesday i did a prolong fast drinking only water and black coffee for approximately 36 hrs until Thursday evening where I had 1 very small meal. The energy and alertness was off the charts after 24 hrs. and I really was not hungry. On Thursday morning i weighed in @ 217 lbs. i'm 65 years old. 6ft tall with about 20 t0 30% body fat. My goal is 190 -200. What I wanted to know was how it affected me and why I was all of a sudden so alert and energized. Thomas just explained that beautifully in the 2 videos. I'll never eat again....just kidding. Gotta get rid of this spare tire.
Thomas can you tell us if we need to take supplements while prolong fasting. And thanks for all the great content.
I'm on day 15 of water only. I had no illnesses or medications so feel fine doing it without medical supervision. I have gone from 168 to 153 so far. I am 69. Not sure how long I will go, maybe 21 up to 40. I feel fine, moderately exercising, walking and some weights. I've been watching Alan Goldhamer from truenorthhealthcenter and the Buchinger channel. I added lemon just yesterday. No coffee or tea. Just water. Herbert Shelton's work, (the modern father of water fasting) is carried on at the NHA site. Do your research and decide for yourself what your next steps are! God bless you.
excellent video & very clear/easy to understand as a non native english speaker ! I'm gonna try this out ! thank you !
Hi Thomas, great videos!
I have a question regarding what benefits there are for the liver and long term or prolonged fasting? Does the prolonged fast help in reparation of the liver as well?
Thank you in advance for your time!
I started fasting to see what would happen. 1 day per week. it went without crisis. 2 days no issue. couldn't make on a three day fast. I noticed I still have energy. I actually eat less afterwards and throughout the week. with this alone I have finally begun to loose weight and feel better overall. I'm also 52 so my metabolism has changed a lot so the time is right for me.
Thank you for all the great info. I enjoy PF, I feel so great when I am on one.
Excellent info and narration, thank you!
Awesome video. My wife and I are planning a five day fast in a few days. I was curious if you have a video that is a little more in depth on how to accomplish the fast. What to eat just before the fast, what fluids are acceptable during the fast? Thanks for all of your advice!
Kind greetings from Fiji out here in the South Pacific.You are indeed blessed that you will be on 5 days Water fast with your wife..I will this week complete my 2 months of 5 days salted Water fast every Monday-Friday,break my fast on mid-afternoon Friday,OMAD (One Meal A Day) on Saturday & Sunday and repeat the cycle the next week.The benefits have been immense,especially on my very significant weight loss.
However,as of next week,I intend to vary my Water fast for 4 days, Monday-Thursday-break fast on mid-afternoon Thursday and next meal on Saturday mid-afternoon,OMAD on Sunday and repeat the cycle the next week..The change in my fasting mode,was due to the drastic drop in my weight..Sir,just humbly sharing my salted Water fasting experience..God's continous blessings to your good self and your wife in your fasting experience...
nothing but water
I am on day 2 of a 7 day fast (with the exception of electrolytes, mineral supplements, ACV, and green tea), and I am feeling amazingly better than I thought I would. Have been doing keto with intermittent fasting for a couple of weeks prior to this fast, so I am off of the sugar cravings, and I believe I am in fat-burning mode now. Also, I am still strength training, and running as usual. My performance is just about the same as not fasting. Looking forward to experiencing the many benefits!
Hey how was ur exp
Awesome channel, and you explain things very well!
Thank you. I appreciate this.
I am now right on my 24th hour of fasting. I created a beast in my stomach that I am about to unleash.
You shit water during a 3 day water fast, ik, I'm halfway through one right now. It's really bad because you think it's just a fart. I thought I was going to let out a squeaker, ended up sharting myself. On the plus side, it's just legit warm water that comes out, so that's nice
loool, never experienced anything like that during fasts
Alex Willis
LOL
you don't shit yourself during fasting if you only eat fruits/vegetables a day before fasting
You shit yourself because your body is eliminating toxins. Same thing happens to me too. Let me guess, that warm water smelled like the deepest pits of hell, well guess what, its toxins...
+Goran Mandic i didn't really investigate to much, although from what I could tell, smelled like a toned down version of regular shit, idk. Maybe my toxins smell different?
Make a video that goes in to more depth about how you should PF. What time you wake up, what time you go to sleep. What sort of workout you do, if any. How much weight you lost, how you felt. Did you take any minerals? Do you leave the room if your wife eats something etc..
Really clear, big thumb up man!
Finally! Thank you for talking about it. I did a 6 day fast and it was awesome. Lost about 5 lbs (after I ate). 2 days after I ate, I broke a bench PR. Still need to lose about 20 lbs so I'm experimenting with 2 days maintenance calories and fast on the third day while maintaining cardio. Day 2 or 3 are the hardest day, after that all the days feel the same, like you would intermittent fasting. The only downside of fasting is the temporary decrease of strength and getting lightheaded all the time.
Tip: Drink 2 gallons of water daily and hide food from sight. Keep yourself busy and don't workout too hard after day 2 because you will recover very very slowly.
Uriel Ramirez Curious... did you workout during your fast?
yes, I did my weightlifting routine with less weight and volume. Other than that, I walked a lot.
Uriel Ramirez will green tea break your fast?
skullviolater 88 no as long as you don't add any sugar. Same goes for black coffee.
Uriel Ramirez cool, I wanna try this! I'm so scared I'll be in a bad mood and feeling weak, though. but as soon as I'm done with the schoolterm in a few weeks, I'll give it a go :D
I’ve been doing 23 fasts (just water and black coffee ) @ 4 times a week for about a year now . I’ve lost 15 kilos , sleep better , havent caught a cold only once in the last 12 months and even have more energy at the gym . The benefits are amazing
Whoa
What's the right time for exercising when intermittent fasting? And when doing prolonged fasting please?
I really like your videos. They are evidence of a thorough and professional work. Thank you.
I got to master the IF before the PF -- I get dizzy without nutrients for too long a period. Again, I hear the experts, but I still listen to my body first.
This guy is a living Legend
Good info. But what about my muscle gains?
1:46 Free fatty acids oxidation starts 2-3 hours after a meal, as soon as insulin goes down. FFA and glucose oxidation happen simultaneously, glycogen doesn't have to be depleted, it only takes insulin to be low enough.
Your videos are really well made. Thank you.
I’ve been fasting for 7 days already with only water, tea and homemade juices and I feel amazing, my skin is sooo clear and I’ve lost 14 pounds!
lol if your drinking juices then it’s not a true fast like he is talking about
Ur doing a cleanse/detox.
This video is helpful to those people that need some valuable information. I like to fast for 24 hours at least twice a week and then I fast for 36 hours at least twice a month. About once a quarter I fast for 96 hours. I have been fasting three years and fasting has improved my health tremendously. I have also lost 40 pounds which put me in the healthy range. I like to eat so I eat pretty much what I want and thanks to fasting I stay in the healthy range.
Very helpful. Well presented, thank you.
Thank you for the wonderful tips!!!
12 hours away from 3 day fast. Was really hungry at end of day 2, feel ok now but still slightly hungry.
Same..I'm doing nine now and was not hungry at all on days 1 and 2 ..only started to feel hungry at about 5hrs into day 3 ..
so, should I study while I'm fasting to learn more?
Thanks for this really informative video! I've been intermittent fasting for a couple months. Will try a prolonged fast. Subscribed :)
Increased stress tolerance sounds amazing. Welldone and thank you for sharing
Incase anyone is wondering, the BDNF (brain derived neurotrophic factors) are produced because prolonged fasting stimulates stem cell production in the brain stem.
@b.cage ...I learned that too from Dr. Mindy Pelz from her fasting video. It's simply brilliant what our body is capable of doing.
I'm on my 4th day of fasting, and today I found this channel. I only drink water, salted lemonade (salt, lemon, stevia), unsweetened coconut water, and consomme, plus a magnesium supplement. I'm planning on going 7 days, and ending it by going straight into a Keto diet.
I love your channel Thomas keep me motivated and backed up without science 😊
I love your videos
Seriously? a twelve hr intermittent fast once a week will result in some benefit? I thought 12 hrs. between dinner and breakfast was pretty standard. I think you need to bump it up to 16 hrs. or more to see any real results.
Lots of people snacking these days. Probably part of why everyone is fat.
Before I started IF, I figured out I had a 13 hour fasting window between dinner n' breakfast. Staying off the carbs, I did in stages, since it was such a huge shift. I soon found that no carbs means less hunger between meals. Now I fast 16-20 hours at least every other day. Plan to do a 24 later this week.
