I've intermittent fasted for the past year. I have lost 100 pounds. Almost limitless energy. No need for anti depressants. Healthiest and happiest I've ever been. I'm 45 years old and in the shape of my life. Massive mental clarity. I have even subsided some of my health problems. I have reversed the aging process. Fountain of youth here folks. I look 10 years younger! So happy. All I can do is smile and dance.
Very happy for you! Accept Jesus into your life if you haven't for your spiritual nutrition! ❤
How many hours a day to fast?
They say donr eat past 8pm and fast for 16 hrs. I 've just started and feel great.
Totally concur…65 years old…and look 10 years younger…im active, physically and cognitively and feel wonderful…I practice fasting variability…18, 20, 24, 36, 48, 72…fast, feast repeat…predominantly plantbased…sort of Mediterranean
@@AGreen-gv7ivI would respectfully suggest 6…there is evidence that early time restricted eating is best…eat more in the earlier hours…I eat 9 to 3
This video has changed my life. I've lost 30 lbs in about 10 weeks! with 20 more to go. and feel great!
+Pete Muse Well done :) Keep it up!
+Pete Muse Good for you! :)
+Pete Muse right on!
how often and how long in each?
+Pete Muse Cool! Keep going!
Keto, Fasting and walking has changed my life. At 55 I feel better then I have in years. Listen to this man, You will live longer and feel better.
Edith Emerson try the whole body vibration plate. Got mine on Amazon. Helps with bone density, increase muscle tone, & lymphatic drainage. I just sit and stand. Takes a month to notice a difference. 10 mins stand, 10 mins sit (hold on to machine).
@@Mengjoanne Thanks for the suggestion on the whole body vibration plate.
Margaret McLaughlin Keto diet can give you the benefits of long term fasting, without actually starving of nutrients.
I AGREE
No
I confess that my hand had started to shake in the past. I tried to deny it. I used to fast a lot, somehow I stopped. I started to fast this year, plus getting rid of sugar and the shaking is gone.Aleluyah
My biology professor fast for 3 days, I do not agree. He looks weak in my opinion and nutrient deficient similar to this guy on Ted talk. The problems with American diet is eating excessively. If eating in smaller portion 3 times of the day and exercise would be healthier in the long term. We can fast occasionally.
Ted Talks can be ego platforms on pointless issues but this man really convinces in a mild and intelligent tone. Wonderful lecture. Thank you Mr Mattson.
yeah, all business
I have found some of the best content on the Internet that I've seen on TED talks, but I still know what mean. A load of inane fluff gets through too. Not that all of that is even without entertainment but there's a lot to sort through at this point.
Simeon Banner ego platform ... wtf
Simeon Banner why he shy to say Islam is very good reference the science now concurs with it, science late over 1400 years, not bad
Good point! (I believe that would be Dr. Mattson not Mr. Mattson...)
If you're feeling slow, fast!
This is a great saying. I might have to use it.
Love!
i was having a bad day, now iam having a good day
Easier said than done! we know the solution but i dont know why following through is the hardest thing
@@MsJrichi No a seven day water fast is easy, it just takes willpower. Now is the perfect time in the middle of winter.

I am a Muslim , I started fasting from the age of 8, at the age of 14 I was fasting for the whole month of Ramadhan, , I am past 70 , and I continue to fast through the whole mont of Ramadhan , always felt great ,
my friend at work is muslim, and he is doing this now, and tired a lot. I have a grandmother that's 96, eats very little, and is sharp as a tac, she says "I don't need that much"
You need Jesus

Allahu AKBAR may Allah bless you brother in Islam
@common SCIENCE I disagree. If your'e not eating, then you're fasting. Breakfast is called Break-Fast for a reason. We fast when we sleep.
I fasted for 5 days drinking only warm water 10 years ago and felt that my brain started working much more clearly. I became also very sensitive, my intuition got incredibly strong.
***** I have a tendency to iron deficiency so I had to eat after five days of fast and I also read that it is better to try and get vitamins and minerals every day with fruits and vegs. Some doctors recommend a fast only when the body refuses food as during an illness. However, I know since that experience that fast is a powerful thing.
***** ya i tried to fast for more than 24 hours the first few went well then i got a little dizzy and felt super weak but at first my brain did feel like it was working better, also participated in ramadan and the first 2 weeks i had like super ninja focus
Ali -V According to some experts, during a fast a lot of proteins and bad substances stored in our body are released from our cells and this is not so good if it is done without cleaning the colon and the intestine with enemas. This is why some people might feel a bit bad at first.
ya i felt good at first but as time went on , but as time went on i was like blehhhh
+Sandra Carli I don't know if it's coincidental or not, but I did notice in the most recent semester of classes that I was very alert, and very sharp. It was as if witty or insightful responses were always right on the tip of my tongue, waiting to be used. I also noticed a sense of enhanced intuition as you noted, as if I could anticipate a professors question or statement, and formulate a response well in advance. And I wonder if this is due to the fact that I was unintentionally subjecting myself to a form of quasi-ketogenic diet. Certain circumstances basically led my diet to be as such: Wake up 7:30-8, go get a large peanut butter infused coffee--cream only, no added sugar--, and go directly to classes until roughly 2pm. Which is far different than my typical morning routine which is to wake up and immediately consume a substantial (although relatively well balanced) meal.My schedule this semester will allow me to do the quasi-Keto diet three days a week, and give me time to do my typical routine the other two. I look forward to examining the side-by-side comparison! :)
Hi. I'm a Buddhist priest. Thank you for this video. I can personally say that intermittent fasting has always been part of our human nature. Have you ever noticed that when you got the flu, you barely want to eat? That's your body screaming you to leave it alone so it can heal! So why is it that you force yourself into having a bowl of chili or soup? Fasting heals you. Make you feel great and the mind is sharp and clear. Most of the Buddhist monastic community worldwide have only 2 small meals a day and this has been going on for thousands of years. So try skipping breakfast. That's all you need to lose weight, lower your carbon imprint and feel great.
Hi, I see you have left your comment here from 2 months ago. Can you share with me how you fast? such as the duration of fasting etc. Also do you usually drink water while fasting?
Tabloharuxx Hi! I fast daily by skipping dinner and once or twice a month I do a 24 hours fasting. It's really simple, actually. I drink water and a little coffee or tea. The first couple of days are hard, but once you start feeling great, you fall in love with fasting. Other benefit is that you get less hungry on your food days, so you lose weight nice and steady. Try it!
I skip breakfast now everyday. I have a hearty salad with some form of protein for lunch and then whatever I like for dinner. I started this for weight loss reasons but I am now so productive during the day and much less easily distracted.
Very interesting point about trying to force feed your body when sick. I do believe in force feeding it water when you are sick because having those stomach convulsions because you have nothing to throw up isn't fun at all, but next time I'll try not eating when I'm not hungry.
Tabloharuxx eat only one meal a day and have 2-3 apple or banana or any such fruits and drink milk eat little bit of nuts, I don't have breakfast in lunch I eat 20-30 grams of nuts (almonds and walnuts mostly) and one apple or banana, I have dinner at 8:30 pm I am indian so I have vegetarian meal cottages cheese, roti, lentil soup, little salad, butter milk etc. I don't drink or smoke Once a week I have my cheat day,I don't like sugary things I love burgers etc. I am topper of my class always a straight A student 😀
An intelligent presentation without hype or sounding like a sales pitchman. He speaks to us as a adults.
As a doctor even
I have got into a weekly routine of fasting, last meal Sunday dinner until Monday dinner, only water for 23 hrs, I feel great and recommend it. I also take a cold shower for 30 seconds after a 3 minute hot one, it's so invigorating even in the depths of winter and people say I'm looking younger. I'm 82.
Cold showers are where it’s at! Great post
@SP Kelly you are amzing! I love you❤
Thank you
Are you healthy with 23 hr fasting a week? I was like that every day for 150 days but of no use. I am 80. i.e. OMAD.
@@R.R.Brahma everyone is different. It works for me, but you have to find out what works for you.
Fasting is incredible, the benefits you get from it are borderline super-powers. They've been shoving the lie that we need 3 meals a day down our throats (literally) for years. Too much food makes you fat, lethargic, toxic, depressed, dishonest, poor and I can go on and on. The hardest thing about fasting is the fear and the withdrawal from addiction to food that you will inevitably go through at first.
Alien Gadfly yeah man agree!
Unrefined Carbohydrates Are the Problem, these raise your insulin. Fat and Cholesterol are not the problem ! Sugar is the Problem that is why your body secretes insulin when your blood sugar becomes too high. Eating healthy fat does not raise your insulin. See this link : www.dietdoctor.com/?s=fat+does+not+raise+your+insulin
sure, starving yourself of energy gives you energy somehow. good thinking
G. Spacepants God bless you!
Yea, just like breaking down your muscles (exercise) makes your muscles stronger.

No you didn't. Why lie?
@@ankitbiswal710 He's lying, so no.
Just wowed.!!! Thank you Doctor Mattson. I'm 60 years old and I have abs, lol. I've been fasting, and during that time, I swim, cycle, spend an hour or two in the gym and it's all paying off. A true lifestyle change, you're preaching the gospel. I went in for my annual physical and my Doctor didn't recognize me in the lobby. All of my numbers, blood pressure, cholesterol, A!C etc. are great. Sharing, and subscribed.
Do you exercise and then continue the fast?
Outstanding! I have been doing intermittent fasting for nearly three weeks and I am burning fat like never before, my former colitis and bloating have almost dissapeared, joint pain has reduced and I do have increased mental clarity in the mornings. I strongly recommend it. I loved the attack against the food and pharmaceutical industries!
Same here buddy 👍
I am on 65th hour of my 72 hour Autophagy Marathon. Fasting is the best medicine for any ailment in a person. From body, to mind, to the soul.

Great video. Thank you sir :). I’ve done the 16/8 fasting and lost 40 pounds in like 4 months, but that didn’t work great for me because I could still not control my hunger, I just couldn’t wait to finish my diet so I can eat bread, cake again. I’m just hungry all the time. A year later I’ve decided to increase my fasting period.For 1.5 months now, I’ve been fasting 36 hours 3 days a week (I don’t eat Monday, Wednesday and Friday). And I feel amazing. My hunger is way way way way down, I can actually manager those urges to eat all the time, I have much more energy, and I feel like my thinking is clear . The hunger still comes in waves, but if I can keep busy for 20-30 min, it just goes away(and is very mild), and I still cook everyday for my husband and son. The only problem now, is that I’m bored, because all that time I used to think about food, now suddenly I have to fill it up with something else... and I lost another 15 pounds... but my greatest achievement of all, is NOT BEING HUNGRY ALL THE TIME
I find that eating grass fed beef, (think fatty rib eye cooked med at most) good quality egg yolks (raw or) and throw in some bacon and a little cheese very satiating for long periods of time. (Former vegan turned carnivore) add intermittent fasting! Good to go!
When I eat enough during my feed window, I find I'm not hungry during my fasting window. All the same benefits, but not hungry.
That's great stuff. Question, What do you after the 36 hour fast?
hunger... always the hunger... did you try low carb diet to control this monster?
I fasted for 6 days and 3 hours and the result was incredible,i became more sensitive to smell and i experience great mental clarity .Life became so easy,things start working better for me,i understand coding syntax more faster .my brain begin to function perfectly as if all the cobweb surrounding it are removed...I must confess that fasting is a powerful tool both physically and mentally.And another extra benefit is that i lost 5kg.
Does that benefit stay when you stop fasting? Like are those benefits long lasting or do they just disappear when you stop fasting ?
Did you do a coding boot camp
My wife's farts are horrific, so I don't want my smell to improve.
@@Justfatty93 Yes it stays if the person doesn't start overeating
@@TheKingsleylove wow you just replied to a 2 year old question, lol
SUMMARY: hungry animals due to fasting or exercise get smarter to look for food. Physical and psychological challenges stimulates the production of "neurotrophic factors" (which helps with the production of new neurons, etc.)
You've summarised one of the benefits but it also reduces inflammation too, which can help people with all kinds of medical conditions. Fasting has also been proven to increase longevity in mice considerably. Maybe next time you want appear to be a smart arse do it properly?
+jayaybe1 thanks for your collaboration, it is always good to serve our youtube community.
Thanks for the summary. I often feel like authors and speakers waste my time by not being concise enough. I'd like to see a new way of relaying information in top down structure with a short summary on the top and then optional information in layers from the top and all the way to bottom (sites and books sometimes approach this, but inconsistently and haphazardly). That way anyone can get what they want and need rather than having a one-size fits all.
***** It's NOT a "summary" if major points have been completely ignored. She was trying to be a smart arse and was found to be sadly lacking.
jayaybe1 I do not know why you seem to be so angry/affected by my "summary" of a long video LOL. I always hope to do good things in life for others (including in youtube). It is not necessary to be so negative to somebody you do not even know. Breath and smile friend 😊🌻, life continues.
Intermittent fasting and keto saved my life. I couldn't even go a couple of hours without needing to eat and was a sugar addict. Lost weight, health issues disappeared (big ones). Absolutely saved me.
Since I began eating once a day, low carb and no sugar, my mood cleared up completely, my thinking is sharp, my tiredness is gone, in all aspects splendid energy levels; now my question is this: why must I have to be 55 years of age to learn this, and in a way which seems totally coincidentally - by coming across KZhead videos? This way of eating and the physical and emotional benefits connected to it, must be taught on a much wider scale on society level.
I've used fasting to rid myself of 70 pounds and three "incurable" autoimmune diseases. I hope fasting is one day embraced as a mainstream solution for autoimmune diseases rather than the palliative drugs pushed by the medical establishment. August 2021 update. I successfully lost 100 lb and arrested for autoimmune diseases as long as I continue in My fasting lifestyle they have not returned. I've been in maintenance of the weight loss now for 2 years. Thank God for fasting. Clearly it does not have the flaws of man-made diets.

I have borderline personality disorder, and I've been doing a low-carb diet and intermittent fasting, has worked wonderfully for me, I been sleeping better (6-8 hours which is alot for a border) , I have less mood swings, and although I know that this will not solve my life 100% at least has helped me alot, i decided to start this diet after i read that it was good for epileptics and schizophrenics , i was taking same medication, anticonvulsants and antipsychotics, so i told myself "why not?" and i don´t regret :D Sorry about my english
+Lana de Ville Be sure to not go TOO low carb. If you dip too low, you will eventually mess with your endocrine system (i.e. disturbed sleep, decreased metabolism, etc). So do include healthy carbs in your diet regularly (e.g. sweet potatoes, beans, etc). No need to take it to the extremity that is ketosis. Best of luck.
AT M thanks alot for your advice! i totally gonna start eating more of that!
+Lana de Ville Best approach with carbs is to have them as a treat at the end of the meal, not as a snack or bulk of your food. Also you could try eating some sardines a few times a week. Vitamin D helps a lot with the mood swings but it may take a few months to have an effect.(all advice from personal experience)
+Lana de Ville Gluten free may also help also. Read the book "Wheat Belly" .. this with fasting will be great for you. For instance, during WWII there were food shortages and a lot of disease actually declined. When life went back to normal and it even got better after the war that illnesses came back all the more.
+Kavetrol i´ll try that too, thank you so much :D

Thanks, Mark for a great talk; you have given me a lot of insights into my current fasting journey. I am 75, and I have had 2 strokes and 3 heart stints. In the last 22 months I have lost ~30 pounds; am no longer pre-diabetic (A1C was 6.0; now 5.5); reduced acid reflux by 95%; reduced blood pressure meds by 75%; ended Celebrex for arthritis pain in knees and hips; have seen increased cognition - a significant increase in typing speed; more bruise resistant than in the past and my skin is less dry and chapped. I have not felt this good in years - fasting is a miracle.
Read John W Armstrong’s book The Water Of Life.
This guy is totally spot on! I started intermittent fasting 9 months ago and took a slow, easy and gradual approach making things as comfortable and natural as possible. I have since lost 100 pounds and I fast approximately 18 hours every day without any struggle whatsoever. Combine this with cutting sugar, carbohydrates and increasing vitamins and minerals, a lot of good things happen!

What type of fast do you do?
I’ve been fasting for 3 months already, combined with 3-4 times a week exercise and lost 35lbs... I feel better than ever! This is TRUE it works!!!!
Great presentation! Fasting boosts clarity of mind and makes you so much more fasted. Whenever I go on a 3 or 4 day fast, skipping breakfast and lunch, I feel so much better overall, though the first day is tough due to the hunger. You gotta stick with it for a few days, then you'll feel better. It helps by resetting your hunger levels.
You still drink water during the "fasting" period (hydration)? Right ... ?

lorna lewis i regularly go two days a week without water or food and i am in the best shape of my life and it heals me spirituality.
I do believe there is something to this. I had some health issues a while that made me lose apetite so I started eating only 1 or 2 meals per day. I got so used to it so even today I only eat a meal at around 5 pm and possible a snack a couple of hours later. Not every day but I do feel a lot healthier compared to when I ate 3 meals plus snacks, like we have all been indoctrinated to do since childhood.

Quit that alcohol crap.
For starters try: 18:6 Intermittent fasting.....(don't eat after 6pm or before 12pm next day = 18 hour fast) Your eat window is from 12pm-6pm (6 hours) .... periodically do a 24 hr fast (lunch one day no eating until lunch next day (24 hour fast).

A small percentage of the population will deny themselves food in a culture of excess. I recently did a 6 day fast. It was empowering and freeing. I'm a 10 year vegan and often skip eating for a day or so and have for years. I recommend people ease into a fast with a clean vegan diet for a couple weeks before fasting to be most successful. The first 3 days are the most difficult after is bliss. (BTW, I'm no kid . . . 60 years old).
I too have fasted for 6 days; for those who are curious, it's quite a high in that all of your senses become heightened and you reach a state of clarity. You are not hungry after 6 days (is true) and by day 5 or 6, you no longer want to "dirty yourself" by eating again (altho you will by breaking the fast properly). I followed a book by Paavo Airola.
Great to see another vegan do the fasting :) Why don't you continue with IF, it is less hard and can be maintained for years every day. It has long term benefits.
I eat a moderately high fat vegetarian diet (about 40% fat). I've started dabbling in intermittent fasting. I love it. But I haven't gone multiple days or anything. The furthest I've gone is miss breakfast and lunch and then workout with weights and running. I think I'm pretty "fat adapted" because that was easy. Frighteningly easy. I still wasn't hungry. I just ate something because I thought it would be a good idea after working out. But I felt I could have gone for days. It's pretty strange.
What's has age got to do with it ? Genuine enquiry as I want to try this and am 60 yrs of age
@@janeflood6664 what have you got to lose
'Communication is the way to improve health' inspiring take home message. what an amazing guy.
Absolutely works, I have never felt happier and healthier. Great talk thank you!
one of the best TED talk I have ever listened to
I used to fast 24-36 hours once a week, I fasted once for 4 days and only drank water. I experienced extreme energy and euphoria as if I was on Adderall. I really need to start fasting again.
you still fasting?
Lee Major ❤️❤️
Same here! Laser focus
Wow
I believe in everything Mark says here. Ive been doing intermittent fasting (only eat from Noon-8pm) for 4 months and I feel leaner, sharper, and more energetic. It works
Are you still doing it? How long does it take to have mental effects in your experience?
Wow! This was 7 years ago. I wish I'd known this before. I just started fasting (Keto-IF-extended fast,four mouths ago). I lost 40 pounds. No exercise. I feel great. The last time I was at this weight was decades ago. If you want an updated take on Keto/Low carb and fasting, watch Sten Ekberg's videos. You need 3-5 days for autophagy. According to Ekberg, you also produce HGH. 3 days of water fasting is now easy to do for me. I am trying to do a 4-5 days fast once a month. The rest of the days, I do IF. Btw, i also minimized carbs and removed processed food from my meal plan. It also saves you a lot of money.
One of the few ted talks which doesnt feel like someones yelling at me about their big idea.
I started doing intermittent fasting now for a little over two weeks fasting on average 20hours daily. and I love it, I have a lot of energy, and mental clarity and the ability to focus for long periods of time. it's the best thing I've ever tried from a physical health perspective. Thank you for the work that you do Mark.
Thanks. Great information from someone who fasts for two days a month and only eats one meal a day. Life changing stuff!
Thank you, it's great to see the science. I just finished a 7-day water, 3-day broth fast. Everyone I told was very very concerned that I was harming my health. But I know better. I feel great!!! Please keep courageously getting the word out.
Congratulations! That's 7 days fast FOLLOWED BY 3 day broth fast? Nice!
Great talk. I discovered fasting pretty much on my own when I was a kid. Always had a problem with the 4-meals-a-day program... I would think, "what's the point of eating when you're not hungry or waiting to whatever hour to eat if you're hungry now?" People is just too absorved in the psycohological structures of the dominant consumerist culture. As Mattson said in the talk, at first it is painful and difficult, because it's hard to break the daily 4-meals program, but once you get used to it, you feel it just makes sense.
Where do you live that has the norm of eating 4 meals a day? Western culture emphasizes 3 meals, but I have never heard of 4.
@@tempestandacomputer6951 Aternoon tea maybe?
@@tempestandacomputer6951 yea I also want to know...
Whenever I ate less or fasted in the past, I always felt sharper, with better cognition, but I´ve never succesfully maintained the habit due to social conditioning and peer pressure. This talk has hopefully inspired me to take my diet by the horns and bulldoze through social norms. I truly expect this to transform my life.
How did it go?
Love the vibe that comes across. I feel that man really just wants to help people live better lifes. Healthier, happier. Thank you Sir
I love it and from now on will start eating only 8 hours a day and 16 hours fasting. I have decided to finish my dinner at 4 PM and have breakfast at 8AM next morning.
If you notice the way he speaks, he appears to have had a stroke in the past. You don't have to have gone through a war to understand PTSD, and this man doesn't have to look like he has gains to speak of his research on intermittent fasting. For all you know, he may have had cancer that contributes to his frailness. He is also older and a hardworking neuroscientist with possible health ailments or issues. His appearance has nothing to do with his delivery of intermittent fasting. Thanks for the wonderful presentation Dr. Mattson.
Hadeer Sinawe Why don't we focus on the noble message that this great researcher is trying to convey ?
Hadeer Sinawe who you are to talk about Mark Mattson? The difference between you and him , is that he is scientist and you are not. he is talking on Tedx and you not
Hadeer Sinawe I'm guessing there's nothing wrong with him . He just looks a little nervous .
I actually did not say anything negative about him! I was defending him. I'm actually a medical student and I know what I am talking about. He has health ailments and that doesn't take away from his message. How lovely you guys can take a comment of support and twist it!
Hadeer Sinawe OK , so , I'm keeping my mind open on this . You're saying that you know some of his medical history ,or you are perceiving from his slight hesitations etc that he's had health issues?
This guy is awesome. I've been using intermittent fasting and it really works.
Ramadan Mubarak to all my Muslim brothers and sisters, all across the globe!
Ramadan Mubarak!!!!...its amazing that the speaker made no reference at all to the fasting done by muslims in his intro
Ramadan Kareem
@@PeterParker-vk7bk :) Peace be upon you Peter.
Abu Amanah and be peace be upon you brother
@truthtruth Ramadan is fasting month, google it, it may not fit your fasting definition of autolysis, hence it’s abstinence from eating and drinking from sunrise to sunset for 30 days. Ramadan Kareem to all Muslims around the globe, blessings.....
Thank you Dr. Mark Mattson and TEDx for making this lecture available!
I’ve just stumbled upon fasting and I’m fascinated by it. I’m always very in tune with my moods and my energy levels and I’m very aware of how I feel. I always eat healthy and exercise everyday and have a relatively physical job in which I’m on my feet for 8 hours, I tried fasting expecting to ‘crash’ about the same times in which I usually would when my body starts running out of energy but my how I was wrong, I feel consistently better throughout the day and don’t feel the same emotional pulls towards food. Try it!
TED talks are amazing. Information flowing straight from research labs to the public, kind of like intersection of science and public thirst for knowledge. Thanks TED for being the platform you are. This talk is an eye opener. Although I have been aware of the benefits of fasting to some extent, this talk drives home the point convincingly. I wish there were ads/campaigns on TV and internet urging people to adopt healthy lifestyle habits like intermittent fasting and exercising and meditation to balance against the blatant campaigns for consumerism all the time.
Fascinating to see how IF was being talked about six years ago.
So true...I just wanted to shed a few lbs for a camera shoot and found that my thoughts, memory and fitness greatly enhanced by doing a water fast. Thanks for this message that confirms my experience.
I just today finished a four day fast and have never gone this long without food and also, have not felt so good in many years. BTW, I am an epileptic and have noticed a noted decrease in my seizure disorder. This guy couldn't be more right about this topic.
Thank you professor Mattson for explain with clarity. I been doing intermitent fasting for over three months and i feel great.
One part that stood out for me from this talk is how the ancient Egyptians created inscriptions 6000 years ago about Fasting. Amazing.
Why? It's a common religious motif. That's why gluttony made its way to the list of deadly sins a bit later.
The bible tells us to fast and pray Jesus did a 40 dry fast.
DTthe 1993 written in coran EGYPtians get them from coran
Hakim & Arts Marine& Arts scene I don’t think so...
Ya the true original Egyptians are a mystery.
I'm older now, but, I still fast. Not strictly, maybe a small smoothie, instead of nothing. Sometimes nothing. I haven't been to a doctor in 24+ years and I'm Canadian, I can go to a doctor, 24/7 for free. I know this will sound off...but, the morning after a day of fasting, I FEEL VERY STEADY. I feel alert. Better than usual & I eat carefully. I don't eat bread because I never liked it, even as a child, & my rare blood type forbids alcohol. I was a professional athlete, but, that has nothing to do with anything, as people point at my riding. No! It is because I eat just the correct small amount.
what is your blood type if you dont mind asking?
@@TheGoldenMossberg I'm wondering also, gonna wait here with you! Perhaps there's still hope :)
@@N3ONLUV for sure! are you considering fasting? if you ever have any questions you can feel free to ask me, and il share my experiences.
WELL DONE ITS SERVED YOU WELL WITHOUT ALL THE DRUGS ETC
@@TheGoldenMossberg can you pls share? I want to know more about others experience on fasting.. Thanks
I read several comments about not skippinng breakfast. I honestly think that I am living proof that breakfast is not required for a healthy physique and lifestyle. I eat everything for the day in about an 8hr time period: a small lunch (very small) and whatever I want for dinner (mostly whole foods, plant-based, vegan.) I feel great, work all day, paint, write, exercise, read, and get 9 hrs (too much??) of sleep everyday ... I really hate breakfast.
Deidra J'Nay ñ
I love breakfast. Is it the same if i eat my breakfast at 10am and then the last meal at 6pm? I am still fasting ?
@@cindyvalencia7291 that's perfectly fine. Your fasting window would be 6pm-10am. Still see results
I fast for 25 years, since I was 8 yo, just because I didn’t have hungry in the mornings. I swear to you, I have 33 years and I went to the hospital only 2 or 3 times in my entire life just because my bronchitis. All my exams always showed good health conditions. If you want to improve your health, try intermitent fasting and low carb diet, it is amazing for health!
he dropped the mic with such grace and softness i loved it.
Thank you, Mr. Mattson. This lecture/lesson has helped me understand intermittent fasting and also helped me increase my dedication to this lifestyle. I currently am trying to stick to intermittent fasting, I find it difficult to not grab a low carb snack in the morning (eggs or bacon, usually). I think that listening to you has helped my resolve.
what a great talk, interesting. I have always understood the spiritual part of fasting, but never knew why physically.
Thank you Mark for dedicating your life to this area. I believe if my Mother had seen this talk she may have reversed her dementia and extended her life. I have started fasting during the 4 months 8/16 everyday and then pushing it to 6/18 occasionally and I've seen a significant improvement in my ability to sleep and weight loss. It does take practice but I convinced that this is the way forward to reduce food related diseases.
Finally the world is catching up with Holy Spirit teachings and healings. Regards South Africa.
I feel like this is a college seminar not a TED talk which I really appreciate.
WOW!! Amazing!!! This really opened up my eyes, thank you so much professor Mattson for sharing your valuable knowledge!!
The ancients knew best and they expressed what they knew with simple powerful clarity.
He presented a lot of useful information and gets right to the point. He is not the most engaging speaker, but if you look beyond that, he makes it easy to understand why fasting is beneficial to your health.
I love this as I also do the fasting and it reversing the aging process
I'd much rather listen to health advice from real scientists than personal trainers or salespeople.

I've intermittent Fasted for the last 6 straight months. I began @ around 235 lbs around 19% bf. Now I dwell around 195 lbs around 12-14% bf. I started off doing 23:1 for about 3 months. I shifted into 20:4 for a couple of months, and I have been into 16:8 ever since. I also did all of this while Boxing and strength training. It was the mental clarity, digestive benefits, and the release from the "bodybuilding" dogma of 5-6 meals per day that kept me going @ first. Now it's part of my lifestyle and it just feels natural. I just want to encourage everyone who has thought about doing IF, but has been too afraid physically or emotionally due to some ridicule that may come from nay-sayers! Try it for yourself and remember that we are to eat to live and not just live to eat. It works! The data from the science speaks for itself.
Super fascinating. The posts made about the personality disorders and depression were equally fascinating and it does make sense that the food now a days MIGHT have something to do with these mental health issues. Super Awesome. So glad I came across this video.
I watched this years ago and it is still my favourite Ted talk
Absolutely working for me i m a muslim i am 39 years old and i m fasting since 30 years for the whole month of ramadan for 30 days. But this ramadan i start running while i was fasting around 10k then add some exercise then add cycling and i m feeling like 9 years old out of 39 years. So many times while running i felt it could be end of my heart at the end it never happened. Thanks to almighty Allah and his messenger Prophet Muhammad (peace be upon him ) who taught us this practice. If one can put himself into a position where only one heartbeat and one breath is the goal of their life then what you think on that situation that will take you to a point where you feel the power of human brain. May Allah bless all humans that peace of mind and tranquility. (Ameen)
I have been fasting for around 10 years. I feel full of energy when fasting, alert, at peace, light, less stressed. Fasting, Intermittent 5/2, Periodic 16/8, 16/800 calories, delayed eating 16 hr fast daily, all contribute to good health. I believe fasting is the way forward to maintain, capture, enhance good health. We have no other option because we have had excess. Fasting lowers blood pressure, lowers cholesterol, creates new neurons in the brain, lowers IGF1 (insulin growthlike factor 1) which we need when growing but not as adults, high levels cause disease like cancer. Increases HGH (human growth hormone) required for repair and to maintain good health. When fasting the body repairs itself 100% and keeps inflammation very low so people don't get Auto-Immune diseases, where the body attacks itself and makes people sick. What is not to like? Enjoy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The longer I fast the stronger I feel. Like I am finally taking control over myself.
IF ,keto and exercise has got me down 100lbs in 8 months. Awesome video.
I have been on intermittently fasting for over a year -- 2 days low calorie at 500 and eating normally the other 5. I love the control I feel because as long as the days are not consecutive you can pick your eating days to match celebrations and holidays. I think for me this is a lifelong lifestyle change and I don't think about it being a diet. I do find my stress levels go up on the fasting days and I am careful on those days not to pick a fight! LOL

In Islam we’re encouraged to fast 2 days a week plus the 3 days when the moon is full. “Eat only when you’re hungry and if you eat, don’t get full”
wrong the highest encouraged fasting in islam is fasting every other day.
It is good hearing a guy as smart as he is speak the truth about the importance of fastin
One of the best TED talks I've seen on this subject.
