- Scientists have been studying the effect on the body's metabolism of fasting, and how it may play into aging. In this web exclusive, "Sunday Morning" correspondent Lee Cowan talks with three researchers on aging - David Sinclair, of Harvard Medical School; Dr. Nir Barzilai, of the Albert Einstein College of Medicine; and Morgan Levine, of the Yale Center for Research on Aging - about the stresses on the body by fasting or caloric restriction, and how it may turn on the body's defenses against aging.

I’ve been intermittent fasting, eating a plant based diet, walking 4-5 miles a day and taking longevity enhancing supplements for years. It works. I’m 75. I feel a good as at anytime in my life. My mind is sharp. I’m agile. I have NO aches or pains. I’m also tremendously grateful.
The research is perfectly clear about the lack of fat soluble vitamins in that diet. You feel good because of the fiber, but your health isn’t actually that great.

@@gruweldaadare you stupid?
Discipline and self restraint are two of the most underrated and the most important aspect of living a healthy life
Amen.
Depending on the person, they can also be two of the most difficult aspects to practice.
Yet... When fasting regularly your appetite and unhealthy cravings adjust quite quickly, and then very little discipline and self restraint is required, it just becomes a lifestyle.
That’s well and fine, but I seriously have no self control. If I see it, it’s safe to say I’m gonna eat it.
@David James uhhh, what’s this got to do with the media?
Cutting out breakfast has been extremely effective for me. The myth that breakfast is "the most important meal of the day" is an outright lie.
Cereal companies like Kellogg’s and Post started that so they could sell their cereals
We know now that skipping dinner would be more beneficial than skipping breakfast.
It depends on the person. I can skip dinner and sleep through a blood sugar drop, but I would have a hard time skipping a morning meal and waiting for lunch. But I swing shift and never get that mid day meal at the same time, so it's impractical.
While I don’t do it every day, I often skip dinner.
Yep. Especially a high carb breakfast! Detrimental and a sure way to gain weight.
I've been intermittently fasting for 15 years, when I started in high school my P.E. teacher used to lecture me about how terrible it was for my metabolism, the same for my yoga instructor in college. Glad to see the science is catching up with what my body told me years ago.
I wish I had known about this in college. Though I believe 15 is still too young as you’re still growing. 👀
@@mesalouis8976 sounds like they are plenty during the times they were eating
@@gatesroyale what?
@@mesalouis8976 apologies I was stating it sounds like they ate plenty during adolescent years
Been have you taken a Telemere test to see what your Biological age is vs your Chronological age?
I have been practicing IF for about 18 months and it changed my life in so many positive ways. I lost 60 pounds, I naturally have more energy, I sleep better, I think clearer, I am more regular, and on and on. At first it seems counterintuitive, but the more I did it and the more I thought about it, I think it makes perfect sense. Think of it in terms of our ancient hunter gatherer days. Humans only ate a couple times a week back then, but they were still sharp enough to hunt for that next meal. The reason is that their bodies were conditioned to focus on repair during those periods between means to ensure that they would survive. Our bodies still have those same mechanisms and all you have to do to activate it is to fast routinely, eat a healthy low sugar/low carb diet and to both strength and aerobic exercise. I started doing all of this at age 50 and I am in better health with more vitality than when I was 25. I have a 6-pack...at age 52 lol
Can you tell us what you did? what was a typical meal and at what times?
@@climeaware4814 I don't have a typical meal. I eat pretty much what I want, excluding a lot of sugar and carbs. It's more about the fasting schedule than the content of the diet, at least at first. These are details you have to work out for yourself because we are all different.
@@dlg5485 what is your scedule?
@@climeaware4814 My eating window is 1pm to 7pm, 2 meals no snacking. Only calorie free liquids (coffee, tea, water) outside of that.
Didn’t people only live to the age of 35 typically years ago? I do wonder if comparing modern life to life of humans years and years ago actually makes much sense. I don’t know though, maybe people only lived till 35 because they only drank alcohol and ate moldy food every day lol
Finally, Intermittent Fasting is creeping into mainstream where it belongs. I started I.F. 3 years ago and my body adjusted immediately. I eat from 9AM to 1PM and the benefits have been simply incredible. I weigh the same as I did in high school, have plenty of energy and a LOT more time to do other things besides shopping, preparing and eating food. And as mentioned in this video, all indications are that I.F. bolsters the immune system, prevents diseases, extends health span and is likely to improve brain functioning. It's probably the easiest way to greatly improve your life in most every way.
Any books you read on timing?
@@MSH3423 I have read several, and watched countless UA-cam videos by experts. There's a wide range of possibilities in terms of adopting a fasting routine that best fits a persons individual situation. At this point, it appears that the important thing is that a person regularly does some form of I.F. The exactly schedule isn't very important, except that it appears important to discontinue eating at least 4-5 hours before sleeping. I tried several different forms of I.F. before finding the 9AM- 1PM eating window ideal for me. My suggestion is that each person experiment and find what works the best.
It was in mainstream media like 4 years ago through Joe Rogen
Same here. Glad it is considered widely now. I started fasting a 20:4 about 8 years ago and everyone thought I was crazy. I'm sharper and healthier than ever.
I started 2 months ago and its equally amazing for me. Only change I need to make is get your schedule and see if it helps with my feeling more cold as winter arrived. I currently eat small meals at 330PM and 730PM. I think if I get an earlier schedule I may generate more heat during my workday when I need it.
Seems counterintuitive, but I did the OMD for a year(one meal a day) for an entire year and could not believe the amount of energy I had. It was the energy and the idea of losing it kept me in the program. Sometimes I slipped out of my lane and noticed how I reacted. I was much more in tune with my body, which means you get to be your own guinea pig. We as a people eat WAY to much food.
Sounds like me on shrooms.
Yes we absolutely do.
for a year? why did you stop? how do you eat now?
@@tohopes Lifestyle change with the China virus bounced me out. When I get a little bit more stability in my life I wanna get back to it. The pandemic caused me to do damage control on my business. Felt so much better, loved the energy. Remember when I would indulge in temptation and buy a pastry I noticed it in my body.
Eat now like I did before healthy as possible, but not one meal a day by any stretch, not near the energy.
Got started on OMD because I was a wee bit paunchy. Never been fat, but just noticed clothes were a little tight. I was maybe 15 lbs over. Wanted to lose it, but the lazy way. So, I just stopped eating and transitioned to OMD. The weight just fell off, then I noticed I was unable to sleep and had way more energy. The idea of losing of the energy kept me on track on the OMD.
If you have never done it. I strongly advise it, if you have the willpower, very much mind over matter. For dropping weight the lazy mans road map. If you can get past that 30 minute window of hunger pangs telling you to eat that crop up every so often you are good to go over. Over time you find that you are really almost not hungry.
@@thyslop1737 i'm glad you found so much success with it. i don't think OMAD would work for me because i'm impulsive and i like to indulge and snack too much. currently i am doing a 5:2 which seems a good fit for me, but for a long time i was doing 3 zero-calorie days a week and that was pretty intense. i've read that fasting activates the hippocampus, which is the expressive and explorational part of the brain.
I agree 100%. I lived this way my entire life until I retired. I relaxed, and gave in to eating three meals a day. I thought I would see what I have been missing. I felt sickly bloated, tired, fat. I went back to my old fasting life, and never looked back. I feel great. Only one meal a day. Absolutly no milk. Yes to whole grain bread. Yes to meat and eggs. Yes to veggies. A balanced diet, but only once a day.
Same i only eat dessert
@moplum Me too! I have the same exact experience!
Why no whole grain bread?
Sadly ever since I retired at 30 I've been"bored" eating and it has certainly destroyed my gut. I used to eat once a day with a coffee in the morning and dinner before 6e... I've always felt my immune system was the best it's ever been. Now I eat 2 times a day and snack well into the night... I've developed stomach issues and extreme bloat. Went to the doctor and they all prescribed the same thing... Nothing works except eating less and once a day, no snacking
@@OpiumBride I understand all this. But, what did the doctors prescribe?
At age 48 (3 years ago) I started to do 16-18 hour fasts per day. Lost 16 pounds (10% of my weight) within 6 months and have never looked back. Gets easier with time. Exercising and good dietary choices also help.

I’m 61 years old and I’m just not that hungry anymore. I’m retired and I thought I would be bored and just eat all the time but nope…One meal a day has been good for me. I know it’s crazy! Haven’t been sick a day for many years.
I think this is the natural way. Our culture nurtures disordered eating, so instead of celebrating all occasions with friends and family engaging, walking, playing we stuff ourselves and demand all do the same. It's maddening how often I talk to people who lie to make up reasons for NOT eating at work and social events to avoid conflict. I'm giving you food now to express my love for you and you must eat it to do the same for me. It's all very unloving when you think about it.
You're welcome
I’ve already been doing this for years now cause it’s always just been what feels best and natural to me. I just turned 30 and my metabolism hasn’t slowed down a bit. Weigh about the same as I did in high school, besides added muscle weight. Feel great. And people wonder all the time how I stay so lean. This video is the truth!
This video changed my life. Been fasting for a month and already feel so much better!
I did this for about six months. Stop eating after 4 p.m. Basically went to bed hungry every night. Slept like a god damn rock. Woke up with tons of energy. Felt slim, looked great feel great. Girlfriend loved the way I looked as well. However i have slipped up a bit. No big deal though.
The sleep angle is underappreciated. I've found not eating within 4 hours minimum of going to be my sleep is so much better.
I can't sleep hungry
i love u karl
I've been intermittent fasting before I knew what it was because I knew how good it made me feel. I generally just eat dinner for about the last 30 years and I look 10 years younger than I am. I even work out and lift weights for 30 minutes a day fasted and go on a long walk fasted and then have a really high quality nutrient dense dinner. I don't have any health problems at 49 years old. Plus you save so much time and money having to worry about food and you can just get on with the business of living your life. I'm not telling anyone what to do I'm just telling you my experience and how fantastic I feel.
It’s really not healthy to work out without having anything in your system. Even if I haven’t had a meal, I at least have a banana or a light snack before working out.
@@BDavis820 It's always worked well for me. My muscle gains are amazing and I have so much more energy in a fasted state. If I did eat it wouldn't be sugar. It would be something like a eggs or cod livers. Everyone has to do what works for them. This has served me well for 30 years.
You look amazing
People who fast already know this. People who don't fast, we welcome everyone.
No thanks. Being hungry all the time just to be on this crappy planet longer doesn't sound like a good trade off
@@travisdejong2354 I'm not sure why you're watching this if your minds already made up. Seems like a waste.
Exactly 😂
@@travisdejong2354 that's the thing, you don't get hungry all the time because most of it is cravings due to your body being used to receive food at certain hour, I've been doing IF for almost a year now and Im leaner than ever and feel better and with more energy and I don't get hungry till around 7pm but even then sometimes I am not that hungry by the end of the day and go for another day of fasting. I thought having to go to work without breakfast or lunch would be a nightmare, but it has simplified my life a lot, now I only have to invest time in preparing good food in the evening when I have more time and not worry about waking up early to make breakfast and lunch or worse, buy something for breakfast or lunch.
👍
OMAD (one meal a day) healed up my hypothyroidism within a month. I now do two meals only with spiritual fasts throughout the year (Lent etc). Lots more time to do other things and save money at the grocery store too. Amazing how our body's adjust and it's no big deal for them. But I also don't eat sugar or gluten and eat organic only, so the transition wasn't hard at all. God bless~
Fasting has helped me shrink tumors ! Correct autoimmune issues and loose 85 pounds . I can not dream of eating outside of my fasting window anymore !! Every time you eat , your body has to work hard to break the food down , when it could be working towards correcting other issues in the body 😉
That's why mom taught us to chew our food properly. The more you masticate the less work your stomach has to do.
@@RealMTBAddict Yes so true , chewing your food properly is important. Although stomach acids will help to break it down .
I'm a firm believer in intermittent fasting and clean, healthy eating.
Ok but what does “clean” even mean? Vegans say they eat “clean.” Paleo dieters use the word “clean.” Macrobiotic eaters claim to be eating “clean.” It’s a word that means whatever people want it to mean.
The term “clean” eating is not a real term and reeks to me of vocabulary used by those whose eating is disordered.
Cutting out any processed foods and chemicals from your diet will change your life
@@JeffreyStock clean eating comes from avoiding processed foods and the most important ones “carbohydrates” specially when it comes on simple carbohydrates, complex carbohydrates are way better since their absorption is slower and they metabolize on the muscle in form of muscle glycogen, while simple carbohydrate are stored on the liver and caused fatty lives disease on the long run
@@JeffreyStock comer limpo é apenas evitar comida industrializada. Não é preciso ser um gênio para entender isso.
I have tried it and love the way I feel and think quickly. Thanks David Sinclair for getting this message out!
I adopted this dietary lifestyle a long time ago. For as long as I can remember, people around me would question it and misconstrue it for an eating disorder. When I donated a kidney three years ago, my surgical team all agreed my kidney was the healthiest they’d ever seen, and that I was among the healthiest people they’d met. I’m also vegetarian and I don’t drink or smoke. It’s not just what you put into your body, but what you don’t put into your body that makes a difference…
When I was in college - I would wake up and rush off to my classes without a moment's thought about being hungry or eating. To me, after a long stretch of sleep - I wake up with a lot of energy and no desire to eat - and even all those years ago, I knew that if I wasn't hungry - it seemed foolish to consume a lot of calories for no reason.
I kept this up my entire adult life - and when people would ask me if I wanted something to eat during the day - I would simply tell them I didn't normally eat during the day - because I felt more energetic and didn't fall into any afternoon 'slumps' - - - and for years - people would look at me like I was crazy when I told them this. At one point I owned my own business - and was surrounded by people 25+ years younger than I was .... and everyday I would show up alert and focused - and my employees would head straight to the breakroom for more "breakfast" - - then complained all day about not feeling well and tired. Everyday.
Whereas I was only getting 3 hrs of sleep a night because my spouse was ill - and I had to do 2 jobs everyday and make sure my kids got off to school - and I WAS UNDER EXTREME STRESS ... yet I had so much more energy and focus than all those 20 something kids did.
I finally felt vindicated when the study on IF came out a few years ago - VALIDATING that going long stretches without eating during that day was not only safe - BUT HEALTHY ... and I have had the pleasure of feeling smug about noticing ALL those benefits - DECADES AGO :)
@@ridgebriar17you are amazing thaaaanks for writing this comment ❤
Dropped 40lb since April due to just eating when actually hungry, not just consuming on demand and craving, discovered I was intermittent fasting. I now do 36-46 hr fasts every 10 days and feel better every day.
Wow so cool. Are you doing it naturally or following anything specific? Where did you get the idea from?
I’ve done intermittent fasting in the past, along with cutting out sugar and refined carbs, and lost 60 lbs. I never felt better. I started back on the same plan about six weeks ago and I can already feel a difference.
It's incredible how much of an online community there is around this topic. Apart from individuals who after talking with me have subsequently tried some form of intermittent fasting, I have never knowingly met anyone else who lives like this. I have even lived in a variety of places in both the US and Europe.
I have been doing this for 8+ years before intermittent fasting, Autophagy were even talked about. This has been in practice in India for a long time. I imbibed it from there and never felt better. I almost do not get sick; even when I do it is sniffles for an hour or so. No coffee or team either - actually no caffeine. Decreases your disease susceptibility dramatically. Side benefit - no aging :)
So, are you immortal now?
Intermittent fasting has really helped me physically and cognitively. I would have never guessed this at all as even when I was dieting in the past I'd eat ever 3 hours or so. One meal a day works well too and my energy levels go way up. The trick is to start out slow and eat really well. Large organic salads, good fats, etc. Once you get into that groove it's easier to fast.
Listened to David Sinclairs book Lifespan after I watched his podcast with Joe Rogan in 2019. I listened to it again early 2021. What a brilliant guy
This man is the reason I got into IF. I strictly do OMAD now with supplements after my meal. I feel great. Blood pressure and blood work is awesome. I’m at a healthy weight. Only thing I drink is water and black coffee during my fast.
I started doing intermittent fasting back in 2012 when the renegade diet was introduced by Jason Ferruggia. Glad to see more people doing this.
Makes sense especially in countries like the 🇺🇸 where ppl eat way too much and unhealthy stuff. Back in my great grandmas village in her country they live till very old and healthy. They dont even know what degenerative diseases are barely anyone ever has somethin like cancer.
There’s people in Africa who dont even know what a plate is and here y’all are complaining about eating. YALL NEED TO BE MORE GRATEFUL
@@againstthepods4316 that argument is very tired, there are also people in africa driving mercedes benz’s, and there are people in Pennsylvania living on the street.
@@LemurJackson I never asked for your opinion
@@againstthepods4316 That's not the point of this video or discussion. Stay in your lane.
@@againstthepods4316 really? There are homeless people in NYC/CA/OR/EVERYWHERE and my sister-in-law in Kenya lives & eats like the royalty she thinks she is. So btc please: sit right down.
So very intriguing! I have been vegan since 1995. In the last few months I have noticed my eating habits tending toward this rule. Interesting.
I won't lie, IF is the way of life, I have been doing it 16 - 18hrs/day since 2018, sometimes I 'shock' my system by fasting 20hrs for a week then revert back. The mental clarity that comes with it is phenomenal.
tsaf hh 2002 shockkcohs HahahaahahaH
I LOVE Dr. Sinclair! He’s brilliant!
I've noticed that many in the united states seem to treat the three meals a day diet as gospel - sometimes even using 'malnutrition' as a way of validating their overeating. I'm glad to see that many are waking up to the fact that eating three big meals a day isn't automatically the healthiest diet for an adult.
Yeah, of course it's gospel. Gospel of food industry propaganda born after the great depression and driven from the modern inventions of the ice box, kitchen gadgets, and modern eras of the 1950's, 1960's advertising campaigns to sell, sell, sell. Sell women this idea of providing a healthy balanced breakfast with all the modern fixtures of butter, milk, and even more processed food products along the way
Maybe it’s marketing- but it’s definitely ingrained in culture.
Well, and it's actually worse than three meals a day. There is a lot of propaganda in the US esp in schools about several snacks a day as well. It's a feeding frenzy.
I don’t think your comment is fair. Americans were not taught to eat 3 “Big Meals” a day. That’s truly an exaggeration! 3 meals yes proportionally balanced !!!
🤔
I do very physical work. If I don’t eat at least a couple of small meals during the day I feel ill.
Yes, people reading books at Harvard and spending the day in a research lab don’t have a broad view of caloric necessity for physical labor. I’m not saying there’s no benefit to some form of fasting but it’s not one size fits all.
There are many athletes who fast/IF and perform well. It takes trial-and-error to figure out how to fast for one's particular body and physical needs.
There is another factor.. Adaptation.. If your body is not used to eat less it is pretty big shock for it.. It os possible to eat less even with physical work, but your body needs adjust..
I've done this and it 💯% works! Thank you for sharing your stories 🙏
I just finished my 24hou fast! I feel great 😊 my blood pressure went down, more focused and just so many benefits.
First day intermittent fasting. 16/8. Did my usual run at hour 15. 23 minutes instead of 25 😳. Gotta be a mistake. 2 days later. 23:10. Wasn't a mistake. 2018. I was 65. Went all the way down to 21:00 during the next 8 months.
Love it ❤️
So true! I've been doing IF for 8 years now, usually 18/6. I've introduced 3 day fasts too as pre menstrual days are awful, I consume way too many carbs in this time so do a three day fast once the cravings are over...the mental clarity is amazing, first time I did it, I couldnt believe I could feel so different...its what drives the motivation to keep doing it as it's not easy, I love food sooo much!
On your 3 day fasts, is it a water fast?
You don't have to delay breakfast to do intermittent fasting. Just stop eating after the 6 hour mark. I eat from 8am to 2pm.
As a Devout Muslim, where we fast by not eating or drinking anything from dawn to sunset daily for an entire month (Ramadan) annually, really happy to see this video!. Definitely agree with his assertion of imporved concentration, sleep and all other benefits fasting (though we do it mainly for religious reasons and get the added health beenfits as a bonus).
mohammed jihad
Muslim region is the way to go the food and the pace brother plus no alcohol, I might start doing Ramadan a go if I'm honest.
Except the no water rule is definitely not healthy for u
Not a Moslem but I've been thinking of practicing Ramadan for health reasons. It makes sense.
yep! Muslims have been doing it for thousands of years. Even non-religious ones.
I'm all for this! In middle age I developed a tendency toward gout, and had to go off red meat altogether. When I maxxed out at 305 lbs I said "enough" and got more aggressive. Now I'm 2 meals a day and just dipped below 180 lbs with no loss of energy or other ill effects.
I just reached this point
Well done 😊👍
Did you do it by also cutting out red meat ?
I eat keto/Paleo, intermittent fasting. Lost 87 pounds since March. I have more to lose, and I am losing that too...
The reason we eat 3 meals a day plus snacks is because of commercialism
no it had been this way for a long time because people were working physically
You mean capitalism
Kunjalo
Intermediate Fasting
I do OMAD since this Summer
That plus Keto and Working out
I was at 219.6 LBS
Now I'm at 181.6 LBS
Wow that is awesome!! I bet you feel amazing too!
Intermittent fasting and prolonged (72 hours about 4-5 times a year) fasting is the best thing I've ever done for my health.
To operate at an optimal level, the body that stays at the edge of survival, it fights more to live than a body that is over fed and always satiated.
Ty CBS for doing this
soooooo interesting and helpful, thanks!!
Happy to see that a story about this subject has made it to the mainstream media. I do however, think that the word “fasting” should be replaced with “eating” because (in our society) fasting is associated with starving, and eating is associated with eating. Intermittent Eating sounds more palatable than Intermittent Fasting to me. Maybe it does to others too?
I’ve definitely skipped breakfast a few times recently out of laziness and started to learn that it’s not too bad, but this idea that it could be good for you is exciting. I’m always struggling to pinpoint what exactly leads to my good days. Yesterday for example, I didn’t have any food until almost noon because I was having a family brunch after church and wanted to save room. And I happened to not eat after 8 the night before. Perhaps that decision had a little something to do with my positive mental/physical state. Maybe I’ll be a brunch guy from now on.
There's zero reason to eat breakfast.
Interesting video, thanks for uploading! 👍
ı've been fastin for 2 weeks ... I never been has kind of energy and looks fit . God bless Dr Sinclair ! 1 Meal a day and 1 hour run . That's amazing for me . I feel everyday energetic.
I have been intermittent fasting almost in 4 months i lost 34 kg and i am happy. Insha allah i will continue rest of my life.
I have monitored my body and diet for 35 years, through lipid panels etc. I agree with these claims 100%. It is hard in the first 2 to 3 weeks as the Harvard scientist says, but afterwards, it is relatively easy. You just have to train your body.
I'm considering Keto but not quite on board due to previous eating disorders. I naturally ended up intermittent fasting by simply eating when I was hungry and I hate to admit it but after the covid 20, I'm seeing many major results in energy and brain function by skipping what we have all been taught to be important beneficial meals.
Fascinating stuff, I love it and it works.
There's lots of ways to successfully do intermittent fasting. Small window of time, alternate days, one meal a day, fasting several consecutive days per month, whatever allows you to reduce dramatically for hits of time regularly rather than overall calorie reduction.
There's also a dirty way, same concepts but eating some junk food and a clean way, eating for mega nutrients instead.
As an MD I have been preaching this for many years.
That Harvard doctor looks so healthy and robust lol
I agree with the guy in the video and am going back to it - I have never looked/felt better except for when I lived this way. Its not a program or anything; I like how the guy sitting down to eat explains it. He is at one with himself and how he handles his intake. Nothing more to it than that. You just don’t have the waste in your system anymore.
WOW!!!!!!!!! THANKS FOR THIS
So glad to read this..I thought I could be damaging my insides by skipping meals but felt so much better before I ate..I eat less now but have yet to give up sugar..
sugar from fresh whole fruit is ok. having sweets only a few days each month is a possibility.
The Food industry did everything in their power to trick Americans into consuming as much food as possible - ALL DAY AND EARLY EVENING.
For many years - there were numerous attempts by "nutritionists" to tell their patients that they MUST EAT 3 times a day - and have healthy snacks every few hours in between - and even back then, all I knew was that all the eating, meant your body was constantly undergoing insulin swings and grogginess because our bodies were expending so much energy digesting food.
One of the best benefits of eating just one meal a day - is you begin to notice how much extra time you have when you are not constantly BUYING, PREPARING AND CLEANING up after 3 meals a day. It also saves a lot of money. WIN-WIN-WIN.
One meal a day for me for the past 2 years. Lost 80 needed pounds.
I refused statins and proved my doctor that it could be done naturally. It’s not easy but once you get it down, it’s a way of life. ✌🏻❤️
I've always believed in fasting. But, didn't know the science. Which makes this video quite interesting.
Nice work.
Great video! Love david sinclair
I totally agree! I’m a vegetarian and do intermit fasting. I can share that I feel healthy light and happy!
Please eat some meat.
-Concerned
If you are vegetarian make sure you get your fats and proteins right.
People we can try all this diets but understand we all have a time and date no matter how healthy you live so enjoy life but with moderately eating
I intermittent fasted for many years. More energy, thinner, less bloating which certainly helped to mask symptoms of the ovarian cancer I didn't know I had. Not making me any younger...
Thanks a lot for this video! I have since several years back only eating one meal per day!
So to go for Intermittent Fasting for 2 1/2 day/week was so easy, nu feeling of hunger!
For a week I did 5:2. I ate modesty 5 days a week and 2 non- consecutive days I fasted until 4:30, eating a light dinner of vegetable soup or salad. By the end of the week I felt so much better more focused and energized.
I’ve been doing intermittent fasting for about 2 years now and I can definitely tell a difference in how I feel. I lost about 15 lbs during the lockdown in 2020 and have gained very little weight since then. I’ll slip up sometimes, but when I’m disciplined, the results are definitely worth it.
Everything he said is true, quit feeding your body constantly. Give it time to digest & heal. I've been doing IF for a few years now, mixing between 16/8 to 22/2 schedule. It works, I feel great.
I’m 29 years old, I’m 5’11 at 208 lb. I fasted for 21 days (water only) and went down to 181 pounds. My diet was absolutely embarrassing. Fast food, processed foods, etc.
Following the fast, I only drink green tea in the morning, a light lunch like sardines or salmon with a salad. That’s it. I feel unstoppable.
I eat twice a day right now. I have given in to some snacking while I finish exams, but once I finish, it's back to twice a day with no snacks.
I have fasted a lot even for 40 days and it is good for you. Intermittent fasting is ok if you don’t binge. The key is creating a calorie deficit. Also, in the initial hours of fasting you are apparently burning glycogen not fat like in ketosis. Ketosis burns fat for fuel which is a surprisingly good fuel source.
So you didn't eat nothing for 40 days ? I'm on a fast now just wondering how long could I go did you drink anything
Just something to share from personal experience: I am from Egypt and as a Coptic Christian if I fast (it is optional to fast BTW) the whole fastings that we have (it will cover about half of the year or even more). Also, before the liturgy, I have to fast about 8 or 9 hours at least to take the communion. I think this video explains why a lot of monks in Egypt live longer.
For about 5 years I did alternate day fasting which meant one day I'd consume no more than 500 calories, and the next I'd eat normally. It worked fine for me, but was sometimes difficult, especially around holidays and vacations. I've been doing IM for about 6 months now, and wish I'd known about it long ago. I generally eat a small snack - not before 3pm, and then a proper meal around 6ish. I don't eat anything after 7pm. I'm also keeping it low carb, but not eliminating carbs altogether because I'm Irish and we love really good bread and spuds😁 I have, however almost completely eliminated sugar. On weekends I allow myself to be a little looser (not with the sugar) but still stick to the time frame.
I don't miss not eating breakfast or lunch, and don't feel I'm depriving myself in any way. I love chocolate and have found some really good sugar free brands. For the first time in my life, I really feel I have an excellent diet - lots of greens, veg, good quality fats - grass fed beef and butter, pasture raised eggs and chicken.
It takes the body six hours to digest food. One should eat no less than six hours before bedtime. Otherwise the body doesn't rest due to working to digest the food. My last meal, and it's small, is no later than 4 pm. I eat around 1 1/2 meals per day. My weight dropped 33 pounds, and it fees great. I am literally never hungry.
Lost 40 lbs doing IF. Started 4 months ago but only do a 16 hour fast. So I eat my first meal at 10am, then lunch when I get hungry and after a light dinner before 6 pm. Trick is to eat lots of vegetables (I get mine frozen from Costco), drink lots of water and of course do some form of exercise.
One thing to be aware of is if you aren't eating enough protein, you're probably losing muscle in that 40 lbs.
@@dreamingrightnow1174 Nope. I'm losing fat. I eat balanced meals with protein and weightlift. IF helps to not overeat. Overweight people have a hard time losing weight because they don't cut down on what and how they eat.
I started doing this due to lack of time… to my surprise I did notice a huge benefit!
It's about time mainstream news allows this message to get out there!! I hope people LISTEN and know this is healthier
I watched the entire Jane Pauley “special” and was sad to see there was NO discussion of gratefulness. I am so tired of seeing people discuss aging as if it’s NOT something to be grateful for, but to fight and sigh about. There was a feeling of gratefulness coming from Billy Crystal. But no real discussion in this special about being thankful. Instead it was the usual griping and how do we handle it…I heard a newscaster say to Jane Pauley that she had just turned 50, and “that was hard!” I thought, no lady, hard is being 30 years old, having two little kids, and looking into the eyes of your husband, and trying to figure out how you’re going to handle the news that you have 4 months to live…that’s hard. I hate this phrase now it’s so overused, but it seems to fit here: tone deaf. How do you get to 50 years old, how do you get to 60, 70 years old and not have known of that exact scenario. How do you get there and not have known someone whose life was cut incredibly short, by accident or disease? So how can you not be grateful to hit those marks. And any discussion of it should go with gratefulness. I am grateful for every ache and pain I’ve got that is due to my advancing age! I thank God.
Very good reminder. Thank you.
I would say that they are speaking on the myth that your body has to depreciate at a high rate as you age. I know a lot of people that chalk bad help up to old age when that isn't always the truth. With that being said, I do agree with you. It is a blessing to be able to live long enough to reach your 50s 60s etc. But I know a lot of people who aren't able to really enjoy those ages due to their poor habits, lack of information and knowledge, and/or lack of self-discipline. Their lack there of manifests itself in amputations, diabetes, HBP, arthritis and other illnesses and diseases that have been said to either come with old age, or that have been deemed hereditary.
They mentioned something along the lines of “you get a bit hungry but you get used to it, it’s a way of stressing your body”. When I did 18/6 I was NEVER hungry and had lots of energy.
You aren't doing it anymore?
My fasting Glucose has decreased from 115ish to under 85 every day since doing this. I eat between 12:00 noon and 6:30 pm daily. I stay very busy and drink water between 10 am and noon, the difficult hours.
The craziest part of this entire video/field of study is that the vast majority of people will ignore it and continue the eating patterns they were brought up on! As soon as I found out about how important time restricted eating is for our health, the very next day I implemented it. First meal 3pm, Second meal 8-9pm.
I ocassionally eat/drink alcohol later than my last meal due to social situations, but I really keep those to a minimum.
"The science is still out on whether this is having a big impact" is the key phrase here.
she was talking about intermintent fasting
The concept of Intermittent fasting emerged from a study about 5 years ago - and it has gained steam every year since then - rather than it becoming just another fad diet that proves ineffective.
With INTERMITTANT FASTING -as time passes, more and more health experts not only approve of 'IF' - additional studies are showing numerous health benefits - including eliminating or radically improving chronic health problems -something that initially no one was expecting....
- and THESE HEALTH EXPERTS NOW ENTHUSIASTICALLY SUPPORT IT. For many it has now become a way of life.
I'd to know the long-term health effects on longevity from caffeine. If caffeine is like a (car engine) turbo for your nervous system, then does reduce the longterm life? A car turbo prematurely wears out the engine.
I’d suggest reading up on the relationship between cortisol levels and caffeine intake. Some interesting findings there.
I've been intermittent fasting for a couple of months.
Just finished my first 3-day fast.
Planning a 7-day fast next week.
If that goes well, 30 day fast in September.
I've lost 75 lb since I started from my high of 410 lb.
I've never had this much energy, mental clarity, or sense of well-being.
Will I live longer? Most certainly longer than I would have at 410 lb. The most important thing to me is my quality of life.
I ran in the yard with my dog yesterday. The first time I've been able to run without my knees feeling like they were going to explode in probably 20 years.
I'm 52 years old and planning to see 90.
Sounds like my lifestyle And we should all be doing it! I preach about it on the weekly basis!
I do intermittent fasting almost every day. My first meal is at 12 noon and is usually a cup of home made kefir with some supplements (quercetin or fisetin, 1/2 teaspoon olive oil, spirulina, cacao powder) plus some berries, all blended together. My last meal is at 7 pm. In between, I east something light (veggies, greens, home made cheese). Such diet does not allow any extra weight and because of that I don't do longer fasting, like for 24-48 hours. Wondering if those who do longer fasting lose weight and if it's their goal to lose weight. My goal is to keep weight stable. I'm the same weight for over 30 years. BMI is healthy (19.7).
It sounds like you've figured out what foods work for your body. The fat is a good idea imo and that and or carbs can be adjusted if you want to gain or lose or maintain. Are you sure you're getting enough protein for your muscle and bone maintenance?
@@dreamingrightnow1174 No, I'm not sure that I get enough proteins. I'm mostly vegetarian, so most of my proteins are plant based. I do eat home made yogurt and home made cheese. Per my blood work, my protein and albumin levels are normal.
I have been employing an intermittent fasting method with an on-off interval of 24 hours: basically if I eat on Monday, I completely fast all Tuesday . On the days that I eat: I am completely free to have whatever I want. On the days I fast: nothing but water is allowed. I’ve been doing this for 43 days now. So far I have lost 17 lbs (7.71 kg). This plan is incredibly easy: it really doesn’t take much willpower to simply skip a day of meals. I never feel “deprived” because again, when I eat: I can have whatever I want with no restrictions. After the first few weeks of really low energy, I’ve seen a huge rebound in energy and a massive boost in mood. I really see no reason to ever go back to eating every single day. Humans were evolved to go days between meals if the hunt went poorly…we’re simply not meant to be in a constant state of being well-fed.
Have been doing intermittent fasting and making Vitruvin Health anti-aging supplement for over a year, and I could say that people who don't believe in longevity would still support those of us who do, coz after all it's NOT just a life, but it's OUR LIFE and we couldn't restore it once it's gone. 😇
I work a labor intensive job and if I dont have lunch , then I can’t work at my best . I just feel weak and drowsy if I dont eat something after working for 4-5 hours in the hot sun . I personally need a lunch break . I’ll have to try this fasting method to see its results
I wait at least 12-14 hrs after last meal of the day to eat anything. Several days a week I only eat one meal. We use to do this routine in 70s-80s. Then I forgot until recently and following a complete physical including blood tests. Big energy difference in just 2 months.
I.F. Definitely feels natural and you see the results inside out. But only problem I've had with 18/6 fasting is that I've shredded too fast and lost a lot of weight. I only started fasting because its simpler to not eat and focus on work and tasks then eat after you finish working. Being slightly hungry also boosts focus.
I’ve always intermittent fasted during work because I never feel like there’s a good time to break focus
Ativem as legendas, para compreensão mais ampla de outras línguas 🙏🏼
Eles falam claramente, mas algumas partes descontraídas, se perdem detalhes 😅
I skip breakfasts on the weekends if I am not working and will not until deep in the afternoon and then have a medium sized meals with snacks. You get so sluggish movement wise and time does seem to dilate from being in a perceived stressed state. It's kind of like running before class, you can focus more in class because your body is so focused on all the energy you just output before class.
This depends on what you eat. When you do a vegetarian or vegan diet you need to graze more throughout the day, especially if you’re busy. This is assuming you’re eating more fresh food as opposed to heavy, processed meals.
I have a friend who is 6'3". He became vegan to try and address his type two diabetes. He got himself off insulin and is now on this type of intermittent fasting program. It's not a problem at all.
I don't think constant feeding is good for anybody, no matter their diet. If there's adequate protein one doesn't need to eat constantly. If they are doing that there may be some blood sugar swings which happens on a lot of grains, especially if there's constant feeding. This is bad for the liver and the kidneys and over produces insulin.
It’s no surprise most of the people are digging early grave with forks
I read about Dr. Sinclair's book "Why We Age, and Why We Don't Have To," very educative. There's no point increasing lifespan without health span. The goal should be to live longer while staying young and healthy. People who say they don't want to live forever should still support this because you can always change your mind later but not if you're already dead. I have been saying this... longevity is our choice! If we want to sustain our health, we have to do something about it! This will start by knowing what supplies our body needs. Start by eating a balanced diet, quit vices, exercise regularly and take an NMN supplement. It's my 7th month taking the NMN by Vitruvin already. It's cost-effective, and I can tell that what I hear from the feedbacks online aligns as well to my experience.
I've done IF many times and it does indeed seem to provide benefits. But, for very active people who need a lot more calories than normal, it can be quite difficult to do both.
I used to do this. The problem is that the research says that people who skip breakfast have higher rates of all-cause mortality. This makes sense, because human circadian rhythms want us to eat in the morning. Our insulin sensitivity is higher in the morning, and declines throughout the rest of the day. My solution - skip dinner, not breakfast.
That essentially comes from one terribly one sided study funded by Kellogg. Seriously, do some research on that and see who was put in the “non breakfast” eaters. Heavy smokers and heavy drinkers and people who slept late, etc.
@@SeanP7195 Perhaps, but the mechanistic research on circadian rhythms I refer to in the last part of my post is still valid, No-one does more (self) research on this than Michael Lustgarten on youtube, and he's adopted a "skip dinner" approach.
@@aquamarine99911 I’m just wondering what happened to humans who didn’t eat breakfast for 1.5 million years. Having food available to eat first thing is a very modern approach. Literally less than 7 decades old.
@@SeanP7195 Not first thing. In fact, it's best to wait for two hours after rising, to let cortisol levels fall. That two hours was enough time to catch a bird or rabbit or eat some insects or grubs or gather berries or dig up a tuber. I doubt that early hominids waited until 6 pm to consume their OMAD.
No breakfast
