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.
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.
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’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.
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.
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
@@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.
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
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.
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~
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.
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.
@@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.
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.

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.
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.
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.
@@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 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.
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..
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.
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.
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.
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.
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.
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.
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’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.
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.
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...
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.
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’ve been vegan for four years, and just started intermittent fasting a few days ago. I already feel so much better. I’ve upped my water and tea intake as well. I feel my body is thanking me in many ways. I’m a fan, and I’m never going back to my old eating habits again.
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 First heard of Dr. David Sinclair watching Joe Rogan pod cast .... am 33yrs old I have 5 months intermediate Fasting and exercising Daily I lost most of the weight and Sizes on the first month, it was super noticeable the change... I started at 195 lbs and now am at 155 lbs ....
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.
Reducing mental fog, fatigue, memory loss & drowsiness, was the main benefits of going hungry a little more, allowing my body to be colder sometimes, by pulse stressing this way, I started to feel & think better, clear & sharp with more endurance & less fatigue. I drink black coffee or espresso early in the morning & water. I eat lunch around 2 pm & stop eating before 8 pm. I wake at 3:30-4am naturally & go to bed around 8pm. I take my medications with lunch or dinner, along with multi-vitamin & a few other supplements like gymnema.
Started out by cutting out snacks, and only eating lunch and dinner. Kept shortening the time window and now I can do only one giant meal a day no problem. Save so much time and only have to think about one meal that I need to prepare. Never hungry either, and I have never felt better
Hmmm, Ive been doing this most of my adult life, but only because Im hardly ever hungry and when I do eat more than a few meals in a day, I just dont feel right. I do drink lots of water and take vitamins and supplements too.
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.
Proper breathing can be extremely effective for both physical and mental health. On a physical level this will result in richer oxygenation of the blood which will result in many health benefits and perhaps even a longer life. But the true power of the breath comes into play when it is used to achieve a calmer and more centered being. You become better equipped to deal with life's difficulties and stressful situations. It can also be helpful in times of extreme grief and bereavement. The book “the full breath” of James Francis explains all this and also explains in simple terms the concept of spiritual development and enlightenment. One of the things that can ruin our health and our lives more than anything else is stress and mental distress. If you know someone who is suffering in life or is in great difficulty, this book could help them fight their way out and become happy and balanced again.
Since this was aired, there have been a few more more in-depth studies over fasting and it seems more and more that most of the benefits come from the caloric restriction, especially with IF. 3 days fast etc seem to be good but you have to limit those if you want to keep lean body mass. I still skip breakfast, and usually eat 4pm to 12pm, this suits my schedule but mainly for the caloric restriction. I like David Sinclair but his studies are in yeast. Unless human or primate studies start to show fasting has some extra benefit than calorie restriction, reducing and tracking your calories seems to be the best method for longevity, along with strength and exercise.
Eat less=looseweight=moreenergy=healthierlife=longerlife... Brilliant! Of course you get more energy when you eat less... how many times have you seen an overweight person struggle to walk or even breathe because of the extra weight being carried.
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’ve been doing IF or eating in a timed window off and on for about 2-3 years and I definitely notice the difference. Women should pay attention to how they feel around hormonal changes and pre/post menopause. Sometimes 16 hrs feels like too much. Sometimes 22 hrs feels like no problem. I just try and listen to what I need, make sure I’m hydrated and go from there. I also try to do 30-60 secs of cold exposure at the end of my showers. Build up to it slowly. I prefer swimming or submersion but don’t always have access.
I know it may not be for everyone but it sure makes me feel better. Also, people who live sedentary lives need to cut back on their caloric intake. People moved a lot more one hundred years ago and their bodies required more calories. We need to adjust accordingly.
THIS is good I have been doing this with cold shower, cold plunge AND YES my body looks a little better, I am stronger BUT THE BEST is what all of these efforts do to your brain. I can only say I feel sharper, more impulse control and don't put things off as I did. I confront issues better SINCE the fasting and cryo-therapy. Here is another tip AFTER fasting break your fast ( YES seems the monks which moderns never give any credit too, were smart all along, they always fast and the break is where we get the term breakfast) BUT your first meal should be a soup with bone broth. NOW your autophagy is kicking with premium fuel. BASICALLY do not put anything in your body that was not on this planet 10,000 years ago, free range, grass fed whole grains. Remember hunter gatherers were bigger, stronger and had blue eyes with dark skin than us farmers.
I have been doing this my whole life, while also being actively playing sports my entire life and it explains why my face looks so "young". I look almost exactly the same as I did 7 years ago, and I am not even 20 yet😅.
omad of greens nuts and seeds. Lots of water coffee juice tea. My bowel movements are perfectly formed and large. Eating too much makes me constipated. Lower intestine is three times the body length and needs to be cleared in between meals. People eat when they are still full from the last meal and this is not listening to the body but cultural conditioning. AKA my parents and their parents were all full of sh**
I've lost 30lbs just by eating every 2 or 3 days. I haven't changed what i eat, when i eat. It's been great. I plan to tweak what im eating to healthier things, but i recommend it!
We muslims go through compulsory fasting in Ramadhan as a way to recalibrate our body systems. We are also encouraged to intermittent fast twice a week at other times. The first week of fasting is slightly challenging, afterwards you don't feel hungry anymore and I find that I need less sleep by the end of the second week.
I’m curious also about the other minor stressors mentioned that can have similar effects to IF. I have a friend who takes cold showers and swears by them. He says he feels great.
So there getting close, but didn't mention a word about what sugar does and what fuels cancer and a ton of other quite important benifits from IF just remember sugar is like money in your wallet and fat is like money in the bank, stop putting money in the wallet and your liver will go to the bank instead
Oh yes. I've dropped breakfast and pushed my lunch to 11-12 somewhere for about a year (I start work at 6 and get up at 5 in the morning to get there). So I'm awake about 6-7 hours before I eat. I function better on an empty stomach, the side effects otherwise is hard to say as I'm also suffering from a chronic illness. I think I would've been worse off by eating all the time. (There's also a half hour walk each way to work)
After about 36 hours your body enters a state of autophagy, your body starts to eat older and dead cells for fuel…this creates the need for the body to create new cells. Intermittent fasting, eating within a short window of time, gives enough time between meals for the body’s hormones, especially insulin, to return to normal leading to less weight gain…less calories are stored as fat when insulin levels are lower.
I’ve been IF for 10 years approx & I look and feel much better. Turned 67 this April and ppl say & family too - that i look 55 or so … hardly any wrinkles.few grey streaks , and I keep my weight down. I do 18/6 and pescatarian ~ Mediterranean diet. I’m sharp as a tack and still work & have no inclination of slowing down or retiring ! For what ?! Lol - what would I do ? I’ve traveled a lot and plan do more. Yet, I’ve been around the world a few times - so I have not missed much :)
My grand mother and my family always eat after sunset, this is as part of religious thing they do. They call it ekabhuktham in sanskrit which literally means eating once a day. And there are several categories of eating once a day.
I've been fasting for over 40 years apparently..lol I'm 47..basically the same weight as I was in high school..(155). The youngest someone guessed my age is 27 and was just a few weeks ago..others at the gathering said...32. They nearly gasped when I told them my age..lol I have no wrinkles, growths, or dry skin. I exercise, eat fairly well and fast intermittently. It's possible it's my genetic makeup, because my older siblings do not look their age as well. IDK..seems like this information is accurate, because fasting also helps those battling cancer recover quicker, because you're starving what the cancer needs to grow.
@zerzzoq7455 hey sorry...just saw your question. Probably not enough..lol I just like to keep busy. Only time I "relax " is around 8:00 in the evening...then the bed calls around 10:30. But...if I were to guess on the calories...maybe 3000? I do eat throughout the day. Eggs, chicken filets. protein bars, yogurt, vegetables, Jamaican patty's...I work in an automotive repair facility...so...whatever the guys offer at the time...that's the extra bonus meal. Cheers!
Really? Please explain. Minority populations in the US have health problems largely due to poor diet and the usual health issues from obesity. Eating less frequently allows one to spend less money while achieving better health.
This dude never smiles or anything, so of course he has no wrinkles. And why would people want to live past 100? It's not like they're walking or doing anything fun. No point in keeping people alive past 80 really.
@@brentwalker3300 Not if they develop some kind of shortcut where you don't have to be healthy to live long. Then one day your bones will just give up and turn to dust.
Tried all diets including intermittent fasting. I’d be curious how fasting affects Muscle Protein Synthesis (MPS)? If you’re pulsing MPS every 3hrs or so, and there isn’t the necessary amino acids present because you’re fasting, it won’t happen. How will your ability to build muscle be affected?
Once you have gotten used to IF, you will never go back to your old ways. Thank God for Dr. Eric Berg. If you are not following him on YT, you definitely should. He has completely changed my life. I'm almost 40 and this is the first time in my life, I've ever felt alive and well.... knowledge is life ❤️

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.
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.
👍
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
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 just finished my 24hou fast! I feel great 😊 my blood pressure went down, more focused and just so many benefits.
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.
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
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.
Ty CBS for doing this
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 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.
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.
I have tried it and love the way I feel and think quickly. Thanks David Sinclair for getting this message out!
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.
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.
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 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 started doing intermittent fasting back in 2012 when the renegade diet was introduced by Jason Ferruggia. Glad to see more people doing this.
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.
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.
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?
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 agree 100%. You feel better, think clearly, look better and everyone asks what’s your secret 😊
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.
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.
I have been doing this for two years. Lost 80 lbs. feel the best I have ever felt. I don’t have a specific time to eat. But one time is enough for me
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...
It won't make you younger but will slow down the process of aging.
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.
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’ve been vegan for four years, and just started intermittent fasting a few days ago. I already feel so much better. I’ve upped my water and tea intake as well. I feel my body is thanking me in many ways. I’m a fan, and I’m never going back to my old eating habits again.
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.
Great video! Love david sinclair
I First heard of Dr. David Sinclair watching Joe Rogan pod cast .... am 33yrs old I have 5 months intermediate Fasting and exercising Daily I lost most of the weight and Sizes on the first month, it was super noticeable the change... I started at 195 lbs and now am at 155 lbs ....
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
Reducing mental fog, fatigue, memory loss & drowsiness, was the main benefits of going hungry a little more, allowing my body to be colder sometimes, by pulse stressing this way, I started to feel & think better, clear & sharp with more endurance & less fatigue. I drink black coffee or espresso early in the morning & water. I eat lunch around 2 pm & stop eating before 8 pm. I wake at 3:30-4am naturally & go to bed around 8pm. I take my medications with lunch or dinner, along with multi-vitamin & a few other supplements like gymnema.
I've always believed in fasting. But, didn't know the science. Which makes this video quite interesting.
Nice work.
Started out by cutting out snacks, and only eating lunch and dinner. Kept shortening the time window and now I can do only one giant meal a day no problem. Save so much time and only have to think about one meal that I need to prepare. Never hungry either, and I have never felt better
I’m an intermittent faster, and just had a long weekend of two or three meals a day, and feel like crap. Tired, mainly, but also seedy.
Hmmm, Ive been doing this most of my adult life, but only because Im hardly ever hungry and when I do eat more than a few meals in a day, I just dont feel right. I do drink lots of water and take vitamins and supplements too.
IF is great but it's best to have your biggest meal either late morning or early afternoon when the sun is at its peak.
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.
Proper breathing can be extremely effective for both physical and mental health. On a physical level this will result in richer oxygenation of the blood which will result in many health benefits and perhaps even a longer life. But the true power of the breath comes into play when it is used to achieve a calmer and more centered being. You become better equipped to deal with life's difficulties and stressful situations. It can also be helpful in times of extreme grief and bereavement. The book “the full breath” of James Francis explains all this and also explains in simple terms the concept of spiritual development and enlightenment. One of the things that can ruin our health and our lives more than anything else is stress and mental distress. If you know someone who is suffering in life or is in great difficulty, this book could help them fight their way out and become happy and balanced again.
Fasting will make you live longer. But that doesn't necessarily mean you will live longer. You can die anytime anywhere anyway.
Since this was aired, there have been a few more more in-depth studies over fasting and it seems more and more that most of the benefits come from the caloric restriction, especially with IF. 3 days fast etc seem to be good but you have to limit those if you want to keep lean body mass. I still skip breakfast, and usually eat 4pm to 12pm, this suits my schedule but mainly for the caloric restriction.
I like David Sinclair but his studies are in yeast. Unless human or primate studies start to show fasting has some extra benefit than calorie restriction, reducing and tracking your calories seems to be the best method for longevity, along with strength and exercise.
would guess this guy does not do physical labor for a living
On the contrary, this allows people to have the capacity for several times more energy, as reported anecdotally as well as prolific studies.
100%.
Eat less=looseweight=moreenergy=healthierlife=longerlife... Brilliant! Of course you get more energy when you eat less... how many times have you seen an overweight person struggle to walk or even breathe because of the extra weight being carried.
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
As someone who runs at least 6 miles everyday would i still eat all the calories i need but only once or twice a day?
I wonder if actual mental stress is a a stressor that leads to longevity.
that's interesting
Mental stress can raise cortisol which can lead to overeating.
@@AA-wc3tw .. and cardiovascular disease.
I started doing this due to lack of time… to my surprise I did notice a huge benefit!
Especially nowadays, it saves me so much money.
I’ve been doing IF or eating in a timed window off and on for about 2-3 years and I definitely notice the difference.
Women should pay attention to how they feel around hormonal changes and pre/post menopause. Sometimes 16 hrs feels like too much. Sometimes 22 hrs feels like no problem. I just try and listen to what I need, make sure I’m hydrated and go from there.
I also try to do 30-60 secs of cold exposure at the end of my showers. Build up to it slowly. I prefer swimming or submersion but don’t always have access.
It’s what’s in your DNA that’s the most important factor for your longevity.
Also, don't have liquids with food. Let your stomach break the food down before introducing anything to drink.
I know it may not be for everyone but it sure makes me feel better. Also, people who live sedentary lives need to cut back on their caloric intake. People moved a lot more one hundred years ago and their bodies required more calories. We need to adjust accordingly.
Fasting. Exercise...cold water exposure...no alcohol..highly recommend!
THIS is good I have been doing this with cold shower, cold plunge AND YES my body looks a little better, I am stronger BUT THE BEST is what all of these efforts do to your brain. I can only say I feel sharper, more impulse control and don't put things off as I did. I confront issues better SINCE the fasting and cryo-therapy. Here is another tip AFTER fasting break your fast ( YES seems the monks which moderns never give any credit too, were smart all along, they always fast and the break is where we get the term breakfast) BUT your first meal should be a soup with bone broth. NOW your autophagy is kicking with premium fuel. BASICALLY do not put anything in your body that was not on this planet 10,000 years ago, free range, grass fed whole grains. Remember hunter gatherers were bigger, stronger and had blue eyes with dark skin than us farmers.
They were black
I have been doing this my whole life, while also being actively playing sports my entire life and it explains why my face looks so "young". I look almost exactly the same as I did 7 years ago, and I am not even 20 yet😅.
omad of greens nuts and seeds. Lots of water coffee juice tea. My bowel movements are perfectly formed and large. Eating too much makes me constipated. Lower intestine is three times the body length and needs to be cleared in between meals. People eat when they are still full from the last meal and this is not listening to the body but cultural conditioning. AKA my parents and their parents were all full of sh**
That all sounds great except the juice part, if it's fruit juice. But to each their own.
I've lost 30lbs just by eating every 2 or 3 days. I haven't changed what i eat, when i eat. It's been great. I plan to tweak what im eating to healthier things, but i recommend it!
We muslims go through compulsory fasting in Ramadhan as a way to recalibrate our body systems. We are also encouraged to intermittent fast twice a week at other times. The first week of fasting is slightly challenging, afterwards you don't feel hungry anymore and I find that I need less sleep by the end of the second week.
My question is, where is your energy level at during the first 4 hours at work? Also, what do you do, first thing in the morning? Do you drink tea?
I’m curious also about the other minor stressors mentioned that can have similar effects to IF. I have a friend who takes cold showers and swears by them. He says he feels great.
I have been doing intermittent fasting now for over 10 years. Longevity NOW!
Funny I never ate breakfast all while we were told you needed to. Short and long fasts are incredible
I stopped eating breakfast and all sugar. Lost 30 pounds and never felt better. 72 years old. No meds.
So there getting close, but didn't mention a word about what sugar does and what fuels cancer and a ton of other quite important benifits from IF just remember sugar is like money in your wallet and fat is like money in the bank, stop putting money in the wallet and your liver will go to the bank instead
Oh yes. I've dropped breakfast and pushed my lunch to 11-12 somewhere for about a year (I start work at 6 and get up at 5 in the morning to get there). So I'm awake about 6-7 hours before I eat. I function better on an empty stomach, the side effects otherwise is hard to say as I'm also suffering from a chronic illness. I think I would've been worse off by eating all the time. (There's also a half hour walk each way to work)
After about 36 hours your body enters a state of autophagy, your body starts to eat older and dead cells for fuel…this creates the need for the body to create new cells.
Intermittent fasting, eating within a short window of time, gives enough time between meals for the body’s hormones, especially insulin, to return to normal leading to less weight gain…less calories are stored as fat when insulin levels are lower.
is eating once every other day ok?
I’ve been IF for 10 years approx & I look and feel much better.
Turned 67 this April and ppl say & family too - that i look 55 or so … hardly any wrinkles.few grey streaks , and I keep my weight down.
I do 18/6 and pescatarian ~ Mediterranean diet.
I’m sharp as a tack and still work & have no inclination of slowing down or retiring !
For what ?! Lol - what would I do ?
I’ve traveled a lot and plan do more.
Yet, I’ve been around the world a few times - so I have not missed much :)
My grand mother and my family always eat after sunset, this is as part of religious thing they do. They call it ekabhuktham in sanskrit which literally means eating once a day. And there are several categories of eating once a day.
Live a physical-labor life,…. like a climbing arborist, landscape-laborer,…. see how you need to eat.
Looked better, aged better, sleep better, think better, focus better - all RIGHT ON the button
Interesting video, thanks for uploading! 👍
soooooo interesting and helpful, thanks!!
I've been fasting for over 40 years apparently..lol I'm 47..basically the same weight as I was in high school..(155). The youngest someone guessed my age is 27 and was just a few weeks ago..others at the gathering said...32. They nearly gasped when I told them my age..lol I have no wrinkles, growths, or dry skin. I exercise, eat fairly well and fast intermittently. It's possible it's my genetic makeup, because my older siblings do not look their age as well. IDK..seems like this information is accurate, because fasting also helps those battling cancer recover quicker, because you're starving what the cancer needs to grow.
@zerzzoq7455 hey sorry...just saw your question. Probably not enough..lol I just like to keep busy. Only time I "relax " is around 8:00 in the evening...then the bed calls around 10:30. But...if I were to guess on the calories...maybe 3000? I do eat throughout the day. Eggs, chicken filets. protein bars, yogurt, vegetables, Jamaican patty's...I work in an automotive repair facility...so...whatever the guys offer at the time...that's the extra bonus meal.
Cheers!
Yes, fast during Ramadan
Praise Allah
Or do it throughout the entire year as a health benefit, not just for a holiday.
@@AA-wc3tw Ramadan is not 'a holiday'
So do you see one of the wisdom behind the month of Ramadan and fasting?
100% white privilege thing.
I can see your point
Wow, great argument.
Really? Please explain. Minority populations in the US have health problems largely due to poor diet and the usual health issues from obesity. Eating less frequently allows one to spend less money while achieving better health.
Thanks
I'm on my third day and already feel better, lighter, less joint pain.
This dude never smiles or anything, so of course he has no wrinkles.
And why would people want to live past 100? It's not like they're walking or doing anything fun. No point in keeping people alive past 80 really.
Generally, those who would live longer would also be far healthier and rely far less on drugs and hospitalization to stay alive.
@@brentwalker3300 Not if they develop some kind of shortcut where you don't have to be healthy to live long. Then one day your bones will just give up and turn to dust.

David is talking about quality of life doing what you enjoy till you die.
OMAD here for 5 years, lifting weight 4x per week.
Where can find the full interview
Tried all diets including intermittent fasting. I’d be curious how fasting affects Muscle Protein Synthesis (MPS)? If you’re pulsing MPS every 3hrs or so, and there isn’t the necessary amino acids present because you’re fasting, it won’t happen. How will your ability to build muscle be affected?
I love how they're sitting down eating while talking about fasting
Once you have gotten used to IF, you will never go back to your old ways. Thank God for Dr. Eric Berg. If you are not following him on YT, you definitely should. He has completely changed my life.
