Possibly your best thumbnail nail ever! Isn't this just an acute response to the perturbation of the glycolytic derived pathways? I would have guessed that all rapidly growing cells would slow down.
I experienced hair loss in 2020 when I unintentionally became addicted to fasting. What began as three meals, no snacks in an eight hour window, turned first into two meals in a six hour window, and then one meal a day. I felt fabulous! I lost thirty lbs. over several months, never felt hungry, had tons of energy, and my mental clarity was unbelievable. But what I didn't realize at the time was my caloric intake had become much too low. And I DEFINITELY wasn't getting enough protein. So it wasn't the fasting that caused the hair loss in my case, it was the starving. I now have very fine baby hairs where I lost it, but it seems to be in no hurry to become thicker and longer. Live and learn! Lol. Love your videos Nick!❤
This is my anecdotal story. I have been fasting since age 11 (one month a year) with unintentional caloric restriction most other days due to low appetite (genetic). Now in my 40s, I still have my hair and look younger than my age. In my experience, this type of food reduction may initially increase hair shedding, but it slows with proper nutrition and adjustment. I don’t recommend extreme hunger or extended fasting without professional guidance-always consult your doctor first.
Hmmm, a hair cycle in humans can last anywhere from 2 to 7 years, so I don't see how a study that lasted 11 days could be relevant. Even "Hair loss due to stress, also known as telogen effluvium, usually occurs 2-3 months after a stressful event". Conversely, FDA approved hair loss therapies take several months to see results. In fact, these approved hair loss therapies can actually cause short term hair loss, before hair starts growing back thicker again weeks/months later. How many study participants where there? Confounding variables? Diets were matched for calories, but were they also matched for nutrients, which are more important for hair growth? And how did they measure hair regrowth over time (a notoriously difficult thing to do).
I've been doing 18 to 72 hour fasts regularly for years without noticing any changes to my hair growth. It has had huge health benefits for me. I use the free fasting app Zero. I eat a carnivore diet with a handful of berries and a handful of nuts daily. Most days, I just eat breakfast. I encourage my friends and family to try it since it has worked wonders for my waistline and every other health issue I have had.
A lot of fasting and low carbohydrate eating for two years didn't really make my hair look better or worse, but I got rid of many cysts on my shins, kidneys, and my left adrenal gland.
I have unintentionally intermittent fasted my whole life (started in grade school). Not a breakfast eater and didn't like taking lunch breaks. Hair is fine. Hair also grows in 3 month waves. So a person could have been in the telogen (resting) phase. I also have fasted for 21 days a few times and zero effects on hair.
I've never been a breakfast eater and I had thick hair prior to having my son. After that hormones have wreaked havoc on my hair. So it has nothing to do with IF but everything to do with genetics and hormones.
Yep, tell me about it. When people found the way to sustain without medication and doctors assistance, suddenly- hair loss, and other alternative information… 😂 One Dr. asked me if I wanted to prematurely die when I told him that I was water fasting every quarter for at least for 72 hours and felt amazing afterwards.
Eating all the time is a killer. Literally. Your body needs time to digest the food we eat but they've found be prescribing three meals and introducing snacking during the day, they could kill us off quicker as doing that would create inflammation in our bodies which would require...you got it...medication.
I have been fasting frequently for most of my life. Hair loss is often linked to an unbalanced sleep schedule. If you're experiencing hair loss, I strongly recommend avoiding all shampoos and using only water to wash your hair for two weeks.
Thank you for talking about how using mice models really are not a one to one comparison. This is a component that is not often talked about by many when making reference to studies. Also, although increasing, so many studies are on men. Women are not smaller men, our hormone make up is completely different and needs to be taken into consideration.
I do intermitent fasting (16/8) and never noticed increase in hair falling. And I over 40. What caused increased hair fall on me was creatine 😢 but I believe it was because of the increased muscle mass, not the creatine by itself.
@@luizfigobr and maybe the hair falling is just your hair cycle. Keep taking creatine and don't worry. After a few years if it's getting thinner and thinner, go for minoxidil.
I, a mid-50ies male, definitely lost hair with 20 kg of weight. I did and do fasting, low carb and exercise. The health and well-being benefits clearly outweighs the hairs. Even with less hair, I look much better now than before, I believe. My theory was that the better lifestyle increased the androgen hormones including DHT and this killed the hair follicles. RIP...
Well, if you aren't eating enough protein, or have an incomplete digestion for protein metabolism, then assuredly the growth of any hair follicles having a lesser supply of protein in the growth shaft, could lead to hair snapping off, falling off, or totally detach, and remain hairless until proper protein levels are re-supplied to the hair follicles.
That thumbnail image 😂😂😂. I lost a lot of hair from becoming resistant to my own thyroid hormone. Straightening that the hairloss stopped but it has never came back to the original thickness.
I did a lot of fasting at one point and my hair did indeed fall out but it was after doing a lot of 48 hr fasts, 72hr fasts and also a 5 day fast in addition to OMAD the rest of the time. Now I just do OMAD and an occasional 48 hr fast and my hair is back to the way it was originally.
Good video. Out of pure curiosity, would you consider using Finasteride if you were to start losing your hair? It also has studies slowing it reduces prostate cancer risk and is now linked to potentially reducing atherosclerosis. Could it actually be a drug that increases longevity or be worth looking into in this regard? Or do you believe the risk/reward is not there?
Did the TRD mice actually maintain their weight? If that "maintenance" caloric input did not go into hair replacement, where did it go? Maybe their bodies had a "starvation" response to the time restriction causing their % adipose tissue increase (deprioritizing hair, nails, skeletal muscle, ...)? Looking forward to the follow up.
If anti-aging was the reason, I'd expect to have slower cell growth (hair and all). You want SIRT to signal a switch to maintenance (and repair/clearance) mode from growth mode.
Now this is entirely my subjective personal experience, but on both side of my family the majority of men (including father and both grandparents as well most first cousins) started balding in their early 20s. According to one of those genetic tests I'm supposedly destined to go bald which checks out. I'm now in my early 30s and no visible hairloss yet. I've been doing intermittent fasting since I were 19 years old. But I might just be lucky who knows. Still interesting study.
Interesting.. Might try IF, if all it does is slow down hair growth. My hair grows way too fast, if I let it go for more than 2 weeks I start to grow a fro.
As a non-scientist: Isn't that also the reason why intermittent fasting is supposed to slow aging - the slower your cells grow, the slower they age, to put it in very simple terms? So the slower your hair grows, you might assume, the slower you lose it :)
The news people take $9B yearly to advertise for Ozempic , Statin, and more drugs They might as well come out and say: “Don’t fast just take these drugs instead”
Why can't they scale mouse timescales in experiments accordingly. Like get a mouse to fast for 2hours which would be like idk 2 days say for a human. Something.
This i anecdotal.. ive tried intermittant fasting for about a year and a half and not noticed any issues with hair loss or regrowth. I think possibly its not the fasting that helps health but actual caloric intake and food quality..it seems those that fast generally take in less calories..
At first glance at the thumbnail I thought "Who is that sexy Captain Picard looking fellow!?" and then I realized it was YOU! Of course it was. Also guys, for what it's worth: Most women do not care about hair loss at all (like not even a thought is given). However I wouldn't want to lose my hair either so I understand the concerns.
If these 'food scientists' put half as much effort into solving insulin resistance that they put into establishing problems with intermittent fasting, type II diabetes would be resolved.
Lol. I have a high chance of going bald according to my DNA passport. I've been doing intermittent fasting for about 10 years and still have pretty full hair. But this is just my anecdote. ;-)
Pretty common problems in hair loss research. Mice experiments and not enough time to see results. What is unexpected is that it doesn't even show hair loss at all! Just shows you how much you can trust these headlines... smh
I just don't get all the hype of intermittent fasting. You're putting added stress on your body. You don't lose more weight if you eat the same. Everyone I personally know who actually does it is completely out of shape and all of the swear it's the best thing ever. Dude, the healthiest, strongest people I know can EAT
One day, a scientist took a flea, put it on a sheet of paper and said "jump!" - and the flea jumped. The scientist took his notebook and wrote: "The flea is very responsive and does what is told!". Next day, the scientist (usually a psychopath) took a scissor and cut off the flea legs and then told the flee to jump again. The flee didn't jump this time. So the psychopath... err, scientist, took his notebook again and noted: "When you cut off its legs, the flee becomes deaf!". Well, this is a joke, of course, but it illustrates quite well the reality of the scientific world (about non-moral experiments and about the "logic" of such scientists... maybe their Absolute God - the money - it's what's dictating from behind the scenes).
I'm going to start stuffing my face every 3 seconds to save my hair.
Sounds good to me, brother.
Lets do it.
Didn't work for me, but it did make me fat.
Cancer- and diabetismaxxing hell yeah. Big Pharma will love you
So, you want to become a Christmas Goose..😂
you look very tired, please take care and have some good rest.
This won't stop me because I'm already bald.
Since intermittent fasting the last 10 years my hair is now thicker and has more colour at 75 then before at 65.
thank you for that Von
Possibly your best thumbnail nail ever!

Could definitely be :)

I want to see studies on how to reverse thinning and graying hair.
Keto Carnivore
My wife is taking sopolina ( not spelt correctly). She claims her grey hair is going. I might give it a try.
@@aurapopescu1875 Nope! a 5 second lookup shows that Keto or Carnivore can cause hair loss.
@@j2shoes288 I’m interested, do you mean spirulina? I couldn’t find anything online similar to sopolina

Slowed growth "rate" makes sense for energy restriction. Probably how life extension is obtained.

you were just genetically predisposed to having hair loss.
Agreed@@Youngbloodmelv
Hair loss follows muscle gain?
@@oolala53 there's a slight corelation due to the increase of DHT in hair follicles. But it all hugely depends on genetics, diet and lifestyle.
@@luizfigobr and maybe the hair falling is just your hair cycle. Keep taking creatine and don't worry. After a few years if it's getting thinner and thinner, go for minoxidil.

Heh, shaft.

I have practiced fasting since 1970 and at 76 I still have more and thicker hair than most young men.
😅😅BAHAHAHA That Thumbnail nailed it!! You made me laugh!! Good stuff!
Thanks :)
That thumbnail image 😂😂😂. I lost a lot of hair from becoming resistant to my own thyroid hormone. Straightening that the hairloss stopped but it has never came back to the original thickness.
Such an important point about 18 hours in mice vs. 18 hours in humans. It shows how easy it can be data to possibly be misinterpreted.

Intermittent fasting since 2002. Turning 79 and still have decent hair.
If anti-aging was the reason, I'd expect to have slower cell growth (hair and all). You want SIRT to signal a switch to maintenance (and repair/clearance) mode from growth mode.
Did this study take into consideration protein, nutrition and stess ?
From my long term multi year intermittent fasting experience 16-18 hours of fasting I can say that my hair indeed grows slower but thats about it.
Now this is entirely my subjective personal experience, but on both side of my family the majority of men (including father and both grandparents as well most first cousins) started balding in their early 20s.

How much money saved on haircuts in a year?
Another way to think about it...
I always shed hair during weight loss. 🤷♀️ It grows back during maintenance.
That'll explain Peter Attia then.
The news people take $9B yearly to advertise for Ozempic , Statin, and more drugs They might as well come out and say: “Don’t fast just take these drugs instead”
Why can't they scale mouse timescales in experiments accordingly. Like get a mouse to fast for 2hours which would be like idk 2 days say for a human. Something.
What exactly is the point of doing a 2 week study on that, like that just seems like a waste of time to me?
Is nipple loss a side effect you didn't talk about? I assume that's what you were checking for a 3:34.
In other words: smaller calories intake resulted in slower hair regrowth. Who would have thought 😮
Well that's pretty cool actually, it's gonna save me money at the barbershop
No way I have aga since 18 years old. Every time fasting makes my hair looks better . The only trap is that very low carbs diet can cause hair loss
razorblading my head since i am 21. would not even let that fungus on my head grow back if i could. so ill pass on the results here 😂
It's exactly the same mechanism that makes fasting cause punctures in car tyres.

It's not a problem for me. I lost most of my hair about 40 years ago.
Was anyone in the IF group genetically predisposed to androgenetic alopecia so the stress of fasting caused hair loss? 🤔
Good question!
Hairloss sure happened to me when I fasted
Harmless studies like this would surely be better done on Lab students and not Lab rats.
Men are not mice.
"Piles of mouse data" is my new euphemism for rodent droppings.
What kind of study is this ? Outrageous 😂😂😂😂😂😂😂
A study sponsored by big pharma and fast food. Who else?
Don t worry bald or not
You look bombastic dude
Immortal, bald, and kpop wig it is then 😎
Everyone knows balding is caused by doing 100 push-ups, 100 sit-ups, 100 squats and 10 km of running, every single day.
well even if, its better to be healthy than not being bald
what if everyone's weight loss was just hair this whole time
Havent watched the video but i want to guess hair likes getting nutrition 😂😂
Lol. I have a high chance of going bald according to my DNA passport. I've been doing intermittent fasting for about 10 years and still have pretty full hair. But this is just my anecdote. ;-)
Noooooo. It would be an afa shame to lose all this red hair….
This study is “splitting hairs”.
Disregard and keep on fasting!
Pretty common problems in hair loss research. Mice experiments and not enough time to see results. What is unexpected is that it doesn't even show hair loss at all! Just shows you how much you can trust these headlines... smh
You clearly fasted
I bet those little bald mice were cute
So…
Save on haircuts,
Save on shampoo,
Save on food and loose weight.
I would say that’s a winner, winner chicken dinner 😂
