Go to DrinkLMNT.com/WhatIveLearned to get a free sampler pack with any purchase! How many of you guys have been fasting? I didn't include too much of my personal experience this time around, but during my 5 day fast I either had lower libido or I was too exhausted from walking constantly to think about sex, but after refeeding my libido was definitely higher than normal
I've been doing daily 20 hr fasting and 4 hr feeding windows, but been eating whatever I want during the 4 hours. Losing about 3lbs a week. I'm going to incorporate more protien though instead of carbs. How does this apply to intermittent fasting I wonder 🤨
Note: One thing that I have always liked about your presentations is the absence of religiosity. Science is not an absolute... like dah. Every time that I have water fasted was while I have been celibate. I noticed no libido change for having no reference I am assuming... and only yucky relationships (that I allowed) before hand. You will have to ask this question later on, for when I did get into a relationship anew... I will have to test that.
I've done a 7 day once. By day 5 I wasn't hungry but I MISSED FLAVOR. Next time I'll try adding garlic powder or juice to the bone broth.
How does all this apply to women?
Can you do some research/video on the Muslim Islamic style of fasting in the month of Ramadan
I remember a Canadian doctor assisting an aboriginal community in BC suffering from obesity having them prescribed a low-carb diet over a period of time to control their insulin levels. Turns out he was able to restore proper hormone and blood levels with a significant weight loss, and patients with mild diabetes were cured improving their lifestyle.
You're referring to Michel Mosely who I think is actually English.
Amazing fact. Thank you.
Low carb diet is a incredibly healthy diet. Dr.Bernstein, a type 1 diabetic and doctor that specializes in diabetes, advises it to all his patients to control blood sugar levels.
The benefits are from the reduced energy in take. When total calories and protein are equated, the randomised controlled human trails shows the ratio of carbs and fat are irrelevant on biomarkers. When I've done low carb vs high carb, and kept protein and calories the same, I notice ZERO difference in fat loss biomarkers taken by blood.

I started doing intermittent fasting (IF) two years ago, weighted 212 lbs. In six months acheived my goal of 160 lbs. My testosterone (T) levels before IF were always bothering me, usually between 230-280 ng/dl. That is borderline low T for men my age (38). After two years of doing IF daily, plus 3 day fasts every 3 months, I'm now at 637 ng/dl, well into the normal range of T levels, also boasting many of the health benefits it also provides to my hormones and body in general. This works!❤
Those are great results but it was probably the weight loss that boosted your test level.

Fasting 16/8 seven days a week is what works for me, a life-changer in fact. Will move to 20/4 when I feel ready. My focus is on the sustainable long run, no extreme changes overnight.

Awesome video, great editing! This kind of information and knowledge is whats making a difference in people's lives.
"Let food be thy medicine" Not only WHAT you eat but How Much, and WHEN. Very important factors. There is something euphoric about fasting.
I always noted that fasting was the biggest factor in allowing me to bulk up, not force-feeding myself, but depriving myself and then watching my appetite become insatiable in the refeeding stage. Best way to put on weight if skinny is to counterintuitively start by fasting.

This feels like such a cheat code, thanks for providing us with this informative video man.
As a muslim, we have ramdan when we fast 30days, each day from sunrise to sunset, but our prophet (PBUH) adviced us to break the fast with "dates" wich is this fruit full of fiber sugar and vitamines and also a sip of water then you have to pray for 30 min or more, wich helps digesting those nutrients.

I'm a firm believer that you don't need to be a doctor, nor should you rely solely on doctors, to understand and improve your health.
That is how people who become sick rationalise.
always on point! 👏🏻
I totally enjoyed this info into fasting. And has confirmed some of my thoughts about fasting
Great video. Production value is superb. Engaging the entire way through. Well done
This reminds me of the “hard times -> strong men -> easy times -> weak men repeat.” Fasting creates strong men, eating constantly makes weak men quite literally. It makes absolute sense, because animals aren’t mean to live easy lives, they are meant to take on hell and come back stronger. Same with damaging your muscles to build them back. We are absolutely astounding things, and we are meant to take on absolutely astounding biological stress, not stress in an office cubical.
I think we are simply bored and people eat out of boredom a lot of the time. Life in a rich society is not particularly "exciting."
from what ive read it seems the current science on the topic is not that you have to "damage your muscles to build them back" but rather stressing the muscles, by pushing them near their limit for a prolonged period, that signals the body to strengthen them. you dont have to feel sore to gain muscle, (an indicator of muscle damage) but if you feel sore you probably pushed yourself harder, for longer, and so the gains will likely be bigger.
Well said
@@kanyewest3811 yes kayne
stress in an office cubicle is hell at its worst.
Yeah fasting works really well, I do intermittent fasting 1 or 2 times a week. Even when I break my fast, the portion of my meal is the same as if I wasn't fasting. Has helped me put on a lot of lean mass and am shredded. I have also been doing the intermittent fasting now for over a year.

I've practiced prolonged fasting for over 3 years now and I've kept making tremendous gains during this time. My testosterone was 894 ng/dl when I tested it almost 2 years ago and my muscle mass and habits have only gotten better since then so I suspect it's higher now. It's also made cutting very easy and reversed any sort of food addiction I ever had. I literally never crave junk food as whole foods taste amazing to me now and I can go very long without every feeling starved even when quite lean. What I've suspected and seems to be true anecdotally is that it boosts hormones and ability to put on muscle mass in the long term.
i agree with you...i dont like vegetable at all but after doing intermitten fasting..i found vegies to be quit delicious..being free of junk foods for 4 year now

@@Dylan-lt9eo It's called dry fasting. People do it and they sometimes do it for 7 days. Dangerous to say the least, but possible.
Your body does not need or want testosterone when it's starving because it's a GROWTH hormone but when you start eating again it needs the testosterone to start growing again.
But fasting increases actual growth hormone

The REAL question is: how long does the testosterone stay elevated post fasting feeding????
Exactly. Nowhere near long enough to counter the loss of test from dieting. If it did you would see natural bodybuilders whose entire career is based around maximizing test doing it. They don't. They bulk and cut at a small calorie deficit.
@@AndyTomlins What works for bodybuilders doesnt necessarily apply to "normal" people, their goal is different to some extent. If you call yourself a bodybuilder, that means you are willing to devote a lot of your time for maximal effects, for the day of the competition. Most people just want to be lean, somewhat stronger with the minimal amount of time, effort and attention. Im not convinced that high testosterone for like 3 days is massively better than 5 days, biology is more complicated than that. A hormonal spike serves as a signal anyways. Also growth hormone is increased WHILE fasting and drops when refeeding as far as i know. Check out Martin Berkhan, he is the pope of intermittent fasting. He is ripped AF and deadlifts like 600 pounds.
@@AndyTomlins Bodybuilders don't matter, exogenous testosterone basically puts all these 'tactics' to shame, anyone who injects will have far higher testosterone than somebody who maxises every single part of their life
@@AndyTomlins most pro bodybuilders don't need to worry about testosterone because they inject it into their veins
@@AndyTomlins bodybuilders inject themselves with large amounts of exogenous testosterone. So your comparison is worthless 🤣

A must watch due to its informative contents.
Man, I love your videos! I wanted to make a quick comment on LMNT. A few months ago I increased my workout program to include several longer workouts and occasional twice a day workouts. I started having horrible cramps within a week of increasing the workout time. I was working out in a warm garage and sweating profusely. My wife suggested some type of salts and I ended up getting LMNT. It put an immediate stop to the cramps! I quit using it and the cramps returned within 5-6 days so now my standard pre workout is an LMNT and 5g creatine. I’ve read things about creatine absorbing better with salt, so why not? I’m now on a 138 day cruise and typically hit the gym 10-12 times a week. I brought enough LMNT to take one a day for the trip. No cramps so far! Legit stuff.
Absolutely, Amazing Insight.
Excellent work as always.
Loved this video, very informative
I did a 33 day water fast (with electrolytes) a few years back. It was actually really easy state the third day. I was very careful refeeding. I had a few spoonfuls of bone broth hours before eating anything.
Yep, the best part is when you can look at stuff like sweets and carb heavy foods yet have zero urge to eat any of it. Not NEEDING to eat is so liberating, like breaking free of a cage you didn't know existed.

Great work man 👏👏👏
Hi Joseph, great video as always. I’m a bit confused by your description of refeeding syndrome. I agree that there is a massive electrolyte flux into the cells, “diluting” the blood, but this would not increase blood volume (10:18) but rather decrease it. Furthermore, my understanding is that the electrolyte imbalance (specifically hypophosphatemia), coupled with insulin’s downstream effects, rapidly depletes energy stores, causing myocardial ischemia, rhabdomyolysis, and respiratory failure, leading to death. I think the myocardial ischemia can cause “heart failure,” if the person survives the acute phase, and the ischemia can decrease cardiac function and lead to heart failure in the more chronic setting. However, I think usually in the acute setting, the electrolyte imbalance causes a fatal arrhythmia, which is the more common cause of death from refeeding syndrome. Very minor correction, but otherwise great video!
Really nice video probably the best and most informative lately thank you ♥️♥️. I just have a question. You're doing OMAD and you're fasting for multiple years now. I expected higher T level's from you. So my question is; how long does this raise last and how often should we fast to get the maximum health benefits with T levels the highest priority?
This is, bar none, the BEST channel in KZhead. Pure gold.
I tried 21 days using water and multivitamins only; I'm used to 7 day fasts every 3 months, yet I was curious to see what would happen. I could have continued but I didn't see any purpose. Given the state of the world today, it might be to everyone's advantage to learn how to suppress hunger.
Yes😊😊😊
Hmm that is why I do feel super great after Fasting in Ramadan.. interesting, thank you
Unless you're not eating at night, Ramadan is closer to Intermittent Fasting or OMAD since you refeed daily as opposed to not eating anything for the duration of the fast. The stress is less on the body for sure but hormone rises are also lower.
Thanks for the information I love the channel Blessed Be.

The one thing I want to know that didn't seem to be mentioned in the video, unless I'm mistaken, was, how long do the heightened test levels last? Does it drop back down after a few days rapidly? Or gradually return to the pre-fast levels? Could there hypothetically be a way to do a fast cycle go increase your over all testosterone levels, or would the benefits be negligible, specifically from a training standpoint.
Bump
i was wondering the same thing. how long does the increase last?
Agreed. Skipped a very if not the very most important part, how long are these benefits present?
Levels remained elevated for a while due to sensitivity to GNRH. I may have dropped a tiny bit a while after, but provided that food intake remained the same, T levels were at least as high as before the fast.
Testosterone levels were indistinguishable one week after refeeding, based on the study cited at 3:44. Probably not mentioned because it does undermine the impressiveness of the results. (Source: Endocrine markers of semistarvation in healthy lean men in a multistressor environment, Friedel et al.)
Nowadays, we are bombarded with a lot of information on how to biohack our bodily systems and functions. But I think that what this VERY informative video shows me is that it can be a very delicate process as well, and adhering to certain rules is key. Knowing what the body can do as a result can be very beneficial or tragic. I'm very thankful for the information provided, hoping it keeps all of us safe in our future health journeys....👍👍🙏
5 minutes in and this video is going hard af!
Currently on a long fast, started 11/26 weighing at 354 lbs to now 12/18 (22 days) weighing at 314 lbs. Total loss so far is 40 lbs, and I feel great. Just water, black coffee, tea, and Himalayan pink salt. Not sure how long to keep going, hoping to drop below 300 by New Years. As far as breaking the fast I have a stock of bone broth ready. And I intend to follow that a day or two later with protein rich yet light foods such as a hard or soft boiled egg, etc. Had labs done last Friday on day 19 and my T levels were just under 800. Mind you I had low T prior to that which motivated me into this fasting journey. Thanks for the ear.

Subjective experience 100% agrees. I’ve always felt like the benefits of fasting hit around 48-72 hours after ending the fast. Say you fast for a day on a sunday.

From personal experience, I can say fasting is amazing for heightened protein synthesis. Years back I did multiple prolonged fasting, starting out doing IF, then worked up to a 2 week(started out 2 days, 3, 5, 7, 9, then 14). Afterwards went to the gym for about 4 months, and got absolutely yolked. My life was also hectic then, working 40+ hours, taking 15 credit hours worth of college courses, and worked out 4 days a week for about an hour each day, and getting on average 6 hours of sleep a night.
Absolute grind
I believe the word is yoked (very muscular) vs yolk (the center of an egg)
I started intermintent fasting 6 months ago. First 12/12, that as too easy, then 16/8, which was better, but hard to get enough protein in 8 hours. My first meal after the short fast is a smoothie that includes a large serving of FF Greek yogurt. Then a half hour later, it's eggs and meat, sometimes avocado. I've lost quite a bit if weight doing this and some work outs. I'm 60.

Last summer, I did *16 hour, *18 hour, and then a *24 hour fast about every two weeks. I gave myself 2 days off on the weekends. The week after I did 5 days of 16 hour fasts. Then back to 16, 18, 24. I tried 24 hour a day off and a another 24 hours in the same week. I did the best on the 16, 18, 24 formula. It made me feel amazing. Loose joints, very little body pain, and mental clarity. I weight train in the mornings and play disc golf while fasting as well. I believe exercising while fasting helps boost the benefits.
Fasting has been single handedly the most helpful diet behaviour that i've adopted to hit my daily/weekly calorie goal. You really get accustomed to the feeling of hunger, almost immune to it or learn to feel little of it. On the other hand, the more frequently I eat the more hungry I am all the time. It's like spoiling your body makes it impatient, disciplining it through fasting and controlled eating intervals makes it patient.
Agreed, with fasting Ive found the biggest benefit is training your food willpower.
I think it's high time you do a video on Iodine. 🙂 There are some interesting differences between the east and west, in terms of iodine intake, and diseases following this, or rather the lack of.
Definitely! Especially considering the other 'Japan' related videos he's previously done, as Japan really stands out in terms of iodine intake compared to the west.
iodine makes me feel amazing
Doesnt iodized salt in practically everything already provide more than enough. Most table salt is iodized...
Better fast Ramadan and then the habit of fasting Monday and Thursdays to see results
I’ve been intermittent fasting (mostly due to a side effect of medication) and this really spoke to me.
What intermittent fasting were you doing?
The "vax"?
@@jbone-0-919adderal and Wellbutrin
@@Hood.Housekeepingyou and me both homie. Amp salts and lamotrigine helps with food intake
This needs to be shown in schools!
I would love to learn what the minimum effective dose for these effects is, just finished a 5 day fast in part because of these but if I wanted to do a less extreme fast more often how many days would be the fewest to see a significant effect. For example would having the weekend as exercise rest days as well as fasting days lead to testosterone spikes in the week that would amplify the effectiveness of hypertrophy workouts? Would the hgh boost boost recovery on those days so recovery is greater? And so on. Would appreciate any knowledge shared
Bless your heart
Very well presented video. New sub ✨👌
I've always found eggs to be a very safe way to break a fast. After long fasts I usually use a bone broth, but always include boiled eggs when I break a fast. I work out pretty hard while fasting and on a ten or eleven day fast I know I lose some muscle, but it comes back so fast on a high protein diet I really don't worry about it. Mostly I keep my fasts between three and five days to avoid the lose of muscle and add more muscle when I break the fast.
yup agree - calculate you last day of fasting with two boiled eggs and that is your meal of the day and the next day add some veggies.
You don’t lose muscle on a fast. That doesn’t happen, your body does not burn anything but fat, glucose, or old protein (through autophagy). You only lose muscle if you don’t use it
Eggs are great for a fast break I believe
Or a break-fast.@@LatinGhost916
Joseph, as allways great video. Cool findings about fasting impat on T. But what about free T ? Because during a fast or carb restrinction diet SHBG allways increases significantly and so goes down free T, although total T stays at the normal or even higher range.
Exactly right. After breaking a fast I still have all the symptoms of low T for weeks afterwards. I believe it's because SHBG will remain high long after T levels level off to a normal range. It's all about free T, not total.
Perfect video, ramadan coming up
I'm glad you talked about refeeding. There is a lot of conflicting information about this. Most agree you shouldn't be eating a lot particularly after a one that is 5 day so longer. Some say you should be eating after a water fast some sugary fruit like bananas or pineapple. I worry about this due to the amount of sugar. I think you are better to start with a bone broth and a small amount of steak or fatty meat.
Just finished a 30 day water fast. Interesting timing
No food for 30 days ?
woah!!!!
>water fast fast verb fasted; fasting; fasts 1: to abstain from food 2: to eat sparingly or abstain from some foods So just a fast then... Don't forget to also specify you wear a *face* mask...
how do people just keep commenting "just did 10 day fast. just finished my 30 day fast" like how fat are you guys for real?
There are water fasts and "dry" fasts where you consume nothing at all. Him saying it's a water fast is a normal distinction between the two. What do masks have to do with it all? Sounds passive aggressive
I started carnivore last month at 186lb, now I am 177lb. I am a bodybuilder and I was eating about 2600 calories to maintain 186lb. My carnivore diet is now at around 3300 calories. Not only did I increase my calories significantly and lost weight, I believe I was mildly insulin resistant or had some hormonal balance even though I was an active person. My strength levels stayed the same. I am assuming majority of the weight lost was fat and water with a little bit of muscle. This video literally explains why carnivore works so well. Meat makes you full for prolong periods of time therefore your insulin isn't always spiking and your're essentially fasting without trying.
check your kidneys, maybe some stones are growing
@@s8i2c Lol
Great video. I enjoyed your points on how a fast can be beneficial. Usually when I fast I will take some supplements. That seems to help me when I go back to eating that steak. Thank you.
Thanks just ordered some LMNT 🤓
As a Muslim who Fast 29-30 Days a Year in Holy Month of Ramadan I strongly agree with this. There is another video on KZhead from Dr. Eric Berg that also highlights benefits of Intermitting Fasting or Fasting in General. Overall this is a Great Video
you dont fast 29-30 days, you do daily intermittent fast
@@ivartorr1469 Yes and that may last from 8 hours to 18 Hours depending on your Location. And its Dry Fast we don't drink/eat anything for that time period.
what would be an ideal fasting/refeeding schedule that can be practiced indefinitely?
Very explanatory, and I would like to know the core structure of a fast, or the way you do it please. Thanks
I'd be interested to see more of the info regarding shorter term fasts. I often do a 20 hr. fast several times in a week, sort of OMAD with a few days of regular feeding. It's worked quite well for me, I think primarily because it has been easily sustainable as a lifestyle.
Hi Joseph - love your content mate! Curious regarding this - I've noticed in your longer form fast videos (7 days & 5 days) you tend to break your fast with hard to digest things like steak etc. Generally speaking I try and break a long form fast (4 days and above) with things like broth and a small handful of cooked vegetables and slowly reintroduce harder digesting foods like red meat & dairy on my 3rd or 4th meal post fast, otherwise my stomach goes all wonky & becomes an unpleasant trip to the loo haha Do you find it is the same with you or can your body tolerate harder to digest foods post a 5 day fast with minimal issues? Great video again mate!
same here. I drink bone broth after a prolonged fast. my stomach can't process the steak or other hard foods and sends me to the poo loo if I dare eat heavy things.
I remember learning as a kid that if you were starving in the desert for a week and made it out, the worst thing you can do is eat and drink like you did before because it can kill you. I was told that but I never knew why until now lol. I do intermittent fasting but I dig trenches in the desert for a living so going whole days without eating would have me passing out. Probably try longer fasting when I'm older.
