Fasting saves: MONEY, TIME, ENVIRONMENT AND ON HEALTH BILLS + gets you more energized and you do enjoy food more WHEN you eat.
Beautifully said.
This doctor told the key word for achieving good health ( eat less). This is 100% true from my view point because I cut down only one meal ( lunch) from my diet and avoided the sugary drinks, the results are amazing. Beside loosing 50 lbs, my pre diabetes and high blood pressure are reversed. I have never seen myself like this in the past 30 years. Eating less works.
Agree 💯
Oddly enough when fasting you get crazy high energy.
I end up eating once per day because I was going through a financial crisis and I had to make sure my preteen had something most of the time to eat. To my surprise, my energy was through the roof in the evenings and the serious inflammation I was experiencing was gone and talk about the weight loss.
Are u serious ?
@@henrykelanit9671 : Yep.
I fast 18 hours a day and have been for months. I could never go back to the way I used to eat. I have so much more energy also.
how do you manage the food, are you eating once per day? or how? and do you drink anything other than water during the fast periods?
What I have learned about fasting is that you can get accustomed to it. Start with a few hours then extend the period of fasting day by day. When started, I used to struggle with 24 hr fasts. Now I can do 2 day fasts and I don't feel particularly hungry. When you break your fast be careful not to overdo it.
What's the right way to break the fast.
@@jhakkuagadhi842 protein meal. No carbs. Meat, eggs or fish to help rebuild the body after autophagy. Small meal then another after 3 hours or more. I take resveratrol before breaking the fast to protect from calorie spike.
@@georgechristoforou991 Thanks 👍🙏
How to start fasting. :|
@@shantanugangele2827 Start by having breakfast half hour later and later each day. Then when it reaches lunch time merge breakfast and lunch. Make sure to drink lots of water or sugar free tea and coffee. Just keep doing this. Then try going 1 day a week without food until the evening. Then after a few weeks try going a whole day without food.
When I walk past the summer terraces at lunchtime and see dozens and dozens of people eating big meals and know they're going to eat again in another 4 hours and probably had breakfast earlier on too, I can scarcely believe it now. It seems nuts.
Food is fuel.
@@jessica3218 When that fuel is not actually used, it becomes poison.
@@jessica3218 fat
Hahaha feel the same!!! 💯
Such excellent advice. Just to eating less real food does wonders, but yes it takes effort and the breaking of old food habits. The worst habit, if it can be called that, is the tendency to eat without thinking about it. Clock-based eating is a real problem. Start small and keep trying after each failure. I have found that brushing my teeth signals to me that no more food is appropriate until the next feeding window. I am slowly working my way down to OMAD at noon for the whole week, with tea and water all day long. How/when you eat also can improve the REM sleep quality and prevent/reduce GERD and related issues.
Both of you are very good Doctors. I highly appreciate your work. Lots of respect.
Its a big lesson for those who deprive themselves of all enjoyment regarding food. I east pretty much what I want in that window and fast about 18 hrs. I have not gained weight or aged much/at all in the past 7 years. This protocol works.
All the gain without the pain.
excellent video/podcast - love that this is spreading. I looked totally different with just doing fasting for a week. first three days i didnt eat, just drank water. I was guided by my doctor, so don't try this unless you know what you are doing.
Great substantial interview with more than useful information.
Thanks a lot for this Great Podcast with the famous David Sinclair! 😊👍
Thanks very much for giving us the longer life and a happy health hapines to all of US
By instinct I've never wanted breakfast or lunch. At dinner I go all out and can eat anyone under the table, but I hate eating after 6pm or it keeps me up at night. So I like dinner about 5. Works for me and people always comment I look young and seem strangely strong/ healthy. I should probably be starting the menopause as my friends are or have already had it, but no sign of it yet.
A lady I know does 1 day a week fasting she's 74 and doing great!
his voice is so soothing
He’s in his 50’s and looks more youthful than a lot of people in their 30’s.
54 even ;-)
@@thesuperbiketour2251 -- How do you know he's using a filter if you were not there in the same room.!?
This ''young looking boy'' has proved that fasting works if he looks 28-36..!!!
It’s a filter but the goal is to look your age or a few years younger!
@@thesuperbiketour2251I agree that he does look far younger when he can control how he looks but I’ve seen him on other peoples videos, he looks decent for his age.
He using filter in this vid
Keep up the great enfirmation so appreciate
Thank you, Dr. Chatterjee.
As someone who just normally only eats once a day, this is a reassuring concept. I think my biggest issue is just needing to work on the quantity of food I eat during dinner. I often still single meal sizes I did in my teens and twenties, and definitely need to cut down. But it is a hard habit to break for sure
Same area I am working on, the portion of the one meal that I eat. Progress though.
Thanks for the video
Never felt better then when I did a 10 day water fast. Mental clarity is on another level
Meaning no food for 10 days? Just water, alone?
I call this bs
@@pbender lol then try it.
@@pbender Why would you call this BS? I've done 5 day fasts and on day 4, the mental clarity is ridiculous, plus your mind is no longer looking for food because you're not hungry. So you have all these mental cycles to spend on learning (whatever you wish to learn). Your brain is fully running on ketones as well.
I did two weeks on green juices and I looked 10 years younger.
What about Ketosis? Does that help? How do you get into a Keto state?
Thank you thank you thank you 🧡
Only eat when you’re hungry. I fast one day a week. I would like to do it for a longer period. But intermittent fasting is helping the body rejuvenate by activating autophagy.
Thank You sooo much Dr.’s
🙏👏👏👏💐💝💐💐
My cuestión is how can i Take my suplentes if I Skip meals diet ?!🤷♀️🤦♀️
Thank You
Amazing thankyou
just be cheerful, have enough sleep, avoid stress, don't be lazy, and eat only when you hungry
Don’t watch or listen to right wing propaganda and fear mongering
wow....awesome info
Even something as simple as eating dinner by 6:30pm, and then don't snack. Wait 3+ hours. Then go to bed and eat again at 7-8am. Not snacking after dinner essentially extends the fast for many people and is a huge improvement over the snacking before bed.
But I love the snacks’
@@blklagoon76 But the snacks... they do not love you back ;)
I used to do long fasts. I found that being in a calorie deficit caused me to stop having my period, made my metabolism reset to lower caloric intake and to have muscle loss. I was not getting enough protein to keep my hormones balanced. Once I started eating what my body needed in both calories and protein macros in a time restricted window, I gained muscle, balanced hormones and started losing fat again. I think fasting once in a while is okay but regularly doing it is actually bad for your metabolic health and muscles. I think the idea is not to be grazing all day long or eating late into the night. Let your body rest and allow insulin to go down but do not become weak, fragile, and hormonally messed up by starving yourself too much.
It all comes down to common sense, if you're full why eat the 3 rd meal ?
The purpose of if isn’t calorie restriction
@@doddsalfa How are you not going to be calorie restricted if you fast 24-72 hours every week like many of these people promote?
@@catcan221 mild cr at best.You need to get in your calories for many reasons,overeat.
@@doddsalfa yet that is what happens when people fast long term such as the 72 hours water fast or 7-30 days. I understand the autophagy goal. That can be done other ways that won't sacrifice your muscle mass.
I am all for TRE. People typically fast every day after dinner until they eat the next day, and that is fine.
I have seen enough research now that says long term fasting is a very bad idea. I used to fast a lot and after doing deeper research, realize why that is not good. Unless you want to be a frail old person who breaks a hip and dies young, build muscle with proper protein intake daily and fast only 12-18 hours a day to let insulin go down.
I do the 18/6 fast starting from 6pm so I'm asleep during most of my fast which makes it way easier. I do this twice a week for a month , twice a year as I do bodybuilding and struggle to keep my size. Would that be enough to gain all benefits though? I also read that its more beneficial to do alternative day fasting so you fast one day then not the next then fast again etc . Unsure why it could be better than just fasting for 2 continuous days though ?
I put collagen in my morning coffee and eat my first meal around 2-3pm then 6-7 pm. 2meals daily.
Does the collagen in coffee considered a meal?
Looking very youthfulness. Sinclair this is fantastic news on fasting
I'd like to know whether we can replace breakfast and dinner with fruit and only have food at noon
I found it rather easy.
I would like to test the NMN on myself, can anyone tell me which company to buy it from? I'm a little skeptical about it
with cautions, please, major scandel in the west on this one with the doctors leaving out the feeding tubes about 15 years ago with hospital patients. It wasn't intentional they just didn't think about it and the nurses just didn't ask, at one point the nurses complained and then other nurses joined in and it briefly hit the news. I am talking about the doctor/patient as seen relationships and doctors have tanked in this dept on second after they propped up the insurance industry, it was the point of no return for one of my loved ones. The nutritional problems creating so many of our health problems these days works both ways. Just a caution, I am trying this method now but I am not strapped down in a hospital and can't speak either
and what about breastfeeding moms?? Is it healthy to fast?
Sinclair looks so young. He looks 25-30 to me. It's amazing. I know that his biological age is in his 20s. However, his chronological age is now over 50 years.
How does one fast as suggested (skip 2 meals) and build/maintain muscle which is essential to healthspan and additionally lifespan?
Plenty of protein when you DO eat!
Actually back in the olden days life expectancy wasn't as long as it is now, and you can't reverse aging, we all eventually die one day.
The best way to live a healthy life, is to live a stress-free.
If hunger and cold and heat prolong our life, why were our ancestors' life expectancy so short?
I can’t get past the nausea if I wait very long, not sure if that’s normal.
Women should fast on certain days of the month, not randomly.
For men, fasting is ok anytime, for women, no. Almost no one talks about these differences that should be highlighted.
Agreed. Dr Mindy Pelz explains the timing (hormones).
There is no robust research showing that daily IF (16:8) causes autophagy or increases life span. It's simply a great way to reduce our daily calorie intake.
Now fasting 1 day or more is a different issue and more research is needed.
there's a little video in your filter, Doctor...
Were Dr. Sinclair suggesting skip breakfast and lunch?
Is it good to fast even if I am really skinny?
More you eat, more your stimulated to eat! Eating stimulates you to eat more, never ever eat breakfast, after one day of fasting your not even hungry! Eat half what your currently eating, greatly improve your health and longevity!
haha, yes, me too.. eat eat eat... However, my parents are relatively short. My brothers and I are all 5.11 - 6 feet... so... the eating a lot I think contributed to that.
It is the mailman or the neighbour.
so treu on change diet, it take a whille to change it complete
You look great
A question to Dr David Sinclair - I am needing research that people may know of, about using Electro Magnetics and Frequencies to wind back the telemerses body Clock. Say books and names of people who have done or are doing research on this subject. Please let me know in here and I will get an email from you tube when you put something in here.
I have just one question, does he dyes his hair?
Is there something going on with one of Dr Sinclair's eyes? Also, are we really fasting? How did we come up with the idea that we should have 3 meals plus snacks a day? Is this cultural, promoted by business? (e.g. cereal companies last century).
Marketing department of food companies in partnership w FDA through donations + "think tank" research
During intermittent fasting, if we feel hungry, do we still wait till break fast time or start eating light or keep drinking water to fill our stomach?
when u are hungry during fasting, drink plenty of water or black coffee or tea . no sugars or milk at all cause calories break fasting :)
Fasting is the key
I wonder who the man upstairs is
Thanks for useful informations, but I wonder is one meal daily sufficient to have all we need from Vitamins and minerals? So we need to take more supliments bills!
I think most of the resources can be found from the Google.
For your question, in my opinion, all pills are human made, like a processed product. Natural food comes first. It also depends what you eat. Carbohydrates must be very very low. Tq.
Some method Sinclair used, I would doubt it, because he is still researching it. Not a final proven products. He is doing now is introduced ideas found from internet.
Thank you 🥰
Now science is saying fasting is the secret of being young and long life but our holidays prophet Mohammad peace and blessings be upon him told him that 1400 years ago…..
That was how people ate long ago, and there are still billions eat only once a day; for some economic problems, for others habits/traditions.
God bless
I've been fasting for about 6 months now by skipping breakfast. I recommend my Mom to IF also but she said her doctor told her skipping breakfast increases dementia and she already has mild symptoms of this disease. What is correct?
I have been skipping breakfast for 7 years, like I don’t eat for 16 hours and only have 2 times meal a day
She shouldn’t skip breakfast then. You should always listen to your doctor, they are going to know your specific history and characteristics. You have to take what you listen to on TH-cam with a grain of salt. The internet should be for entertainment not medical advice!
@@mattg5978doctors know NOTHING learn NOTHING about nutrition, vitamins, alternative methods...which work. Oh boy.
How do you skip a meal if you do a physical job?.....or does doing a physical job , require no fasting?
You just do your job. Your body will quickly adapt over 2-4 weeks. I workout while fasted, and it's pretty long intense strength training, and I still don't feel hungry until late in the afternoon.
just be cheerful, have enough sleep, avoid stress, don't be lazy, and eat only when you hungry
Your body will adopt to it. I do physical job and being in front of foods all the time. It’s self discipline 💪
Self discipline and I also put salt in my water to drink through the day to keep my electrolytes replenished and my energy up (Himalayan Pink Salt and Potassium Chloride)
Hope this helps!
@@jacoblewis2461 salt is salt, whatever form it is. And too much sodium in the body does harm rather than good
encluding the materials things😕😄
I have to disagree about animals. My cats live to be very old because they are loved. They eat whenever they want. But it’s true with humans.. like clearing yourself.
How long do your cats live?
dinner only from last 15 years
It has generally not worked well for me. In my 20s I regularly skipped breakfast daily and dinner a couple nights a week and lunch on the weekends and I was more unhealthy than I've ever been. No energy. I was also during this time underweight, needless to say, despite really stuffing myself during that one or two meals I'd have. I'd have random days where I'd wake up completely drained, feeling wiped out. I still get these sometimes but not with nearly the same frequency as before. Now I strength train which requires pretty regular eating. My energy level has stabilized as has my mood. I'm sure there are great benefits to fasting for the typical overweight and sedentary American, but for me the fact that our ancestors did it by no choice of their own isn't enough to convince me we are healthier following suit. Our ancestors also lived to an average age of 35 supposedly.
But if I eat at 5 am as it’s a professional hazard what does that mean if I eat again at 7 pm!! I thought that the food inside the body will be digesting till 7 pm so actually I’m not fasting !! Please clear this doubt for me
Yes, you need at the very least 12 hours to get into a fasting state.
Doesn't taking Metformin mimic fasting and limit mTor
what an epic story of the univers miracle magic.👽🙉🙊
I do a monthly 5 day water fast preceded by a colon enzyme flush and I end with a liver enzyme flush- very powerful
2-3 times a week I fast 18-20 Hours
I also am plantbased and high raw
I lift weights three times a week and do yoga 2-3 times a week
I am almost 50, not on any hormones and feeling great
No cosmetic work done either
I eat 4 days in a week, and fast 92 hours without drinking water in a week. Since 2 years ago.
@@chajchaallpachu 92 hours without water ?
He definitely didn't throw that t-shirt on last minute
Mice fasting 16 hours out of 24 hrs does not correlate to people fasting 16 out of 24. 1 mouse hour does not correlate to 1 human hour. A 3 day fast for a person is more equivalent to 16 mice hours of fast.
If I starve for so long my sugar drops and then I get v bad migraines so please help me
That will only last until your body becomes more "metabolically flexible" and is able to switch from burning Glucose (food in the mouth) to burning fat stored in your adipose tissue. The headaches are in many cases caused by either withdrawal from sugar (either actual sugar or carbohydrates), a lack of water and minerals, and sometimees even an innordinant amount of toxins being released during the fat burning stage. Bottom line, it goes away. Be sure to drink enough fluids, and make sure you have enough minerals in your meals to help your body chemistry when not eating.
Your not Starving…..eating one healthy meal a day is more than many of your ancient ancestors had and they survived without any medicine or technology…..
I believe that electrolytes may help you.
If you have a medical issue like that, do consult a medical professional.
I’m prone to migraine as well. What I do is drink black coffee in the mornings and lots of water. When I start to get hungry I drink more water. When I have the first signs of getting lightheaded or even slightest signs of headache I eat immediately. My body has slowly been able to fast this way longer and longer without food 😊.
Doesn’t that waste away your muscle though?
No. It actually causes growth hormone to kick in, after about 18 hours of fasting.
@@pm6613 do you should even workout fasted then ?
@@tealatata I do. I've lost a lot of weight fasting and am very muscular. Your body will burn fat and excess skin connective tissue first before muscle.
@@tealatata Yes you can or Id rather you should. When doing intermittent fasting there is no reason to avoid workouts, you still have a lot of glycogen stored in your muscles. But when you do a prolonged fasting you need to adapt your training a little bit. It means less weight in strength training and staying in zone 2 in endurance (avoid zone 5).
Not stopping your workouts in a prolonged fast permits you to lose weight (mostly fat) far more quickly and to lose less lean mass.
I'm on my 6th day of fasting and keep doing my strength and endurance training : I already lost 6kg : that's 1kg/day. When I fast without doing my workouts, after 2 or 3 days, I lose far less than 1kg generally no more than 300 - 400 g a day.
@@Noegzit I don’t need to loose weight I’m interested in building muscle though since we loose so much through aging. I’m at 20% body fat do t want to get leaner then that.

So Fasting, Reservatrol, Metformin, sleep, working out.........Life Force by Tony Robbins

I have a doubt red wine is good or bad because it contains alcohol too
grape juice does the same for your body no alcohol.
Fun fact: When I grew up there were ALMOST NO FAT kids, but now they're EVERYWHERE, I'd say 2/3 or more are over weight.....so SKIP SNACKS for kids for SURE.

Dr David, does botox help aging? :D
Good that you do not get that afternoon slump.
Looks like Dr. Sinclair is not in tune with Dr. Panda... Though both theories are the two sides of the same coin
Live short and be comfortable or long and be miserable ;).
THIS COULD EASILY BE THE ''FOUNTAIN OF YOUTH'' - F A S T I N G - IT SEEMS THAT FOODS AND EATING 3X A DAY IS ACCELERATING THE AGING PROCESS. SO LESS FOOD TURNS BACK THE CLOCK, & STOPS AGING. !!!
Excessive food makes you old, fat, lazy, diseased, and less food gives you longevity, health and youth. Inspiring video.!
this is opposite to the findings Huberman shared.. He said that the intermittent fasting results seem to not be the eating window but the the calorie intake could be much better managed due to having given times when to eat and not but that the non-eating time really was not the driving force, but the old school idea of having control of calories in and calories out was most likely the real reason to weight loss.
The Myth of Fasting for Longevity: Why We're Already Living Longer Than Our Ancestors
In recent years, there has been a growing trend towards fasting as a means of improving health and longevity. The argument goes that, in our modern world of abundance and constant access to food, we have lost touch with the natural rhythms of our bodies and the way our ancestors lived. By fasting, we can reset our biological clocks and potentially extend our lifespans.
However, this argument is based on a flawed assumption: that our ancestors lived shorter lives than we do today. In fact, the opposite is true. While life expectancy has certainly increased in the modern era, our ancestors were not necessarily doomed to short, brutal lives.
Studies of ancient populations have shown that, on average, humans in the Paleolithic era (around 10,000 years ago) had lifespans similar to those of modern humans. This is despite the fact that they did not have access to many of the modern medical and technological advances that we take for granted today.
Furthermore, there is evidence that our ancestors practiced a form of intermittent fasting as a natural consequence of their hunter-gatherer lifestyle. They would go for extended periods without food, then feast when the opportunity presented itself. This suggests that our bodies are well-adapted to periods of fasting and feasting, and that we do not necessarily need to adopt extreme fasting regimens to achieve optimal health.
Of course, there are certainly benefits to fasting, such as improved insulin sensitivity and weight loss. However, it is important to question the idea that fasting is necessary for longevity, or that our ancestors were somehow inferior to us in terms of lifespan. By understanding the ways in which our bodies have evolved over time, we can make informed decisions about how to optimize our health and wellbeing, without succumbing to fads or myths.
DOESNT yogurt break your fast ? You say you skip breakfast and lunch but you’ll have a little bit of yougurt
Wow! If adversity keeps one young, people in d more ancient times must have had lived longer lives than we do today. Has that been shown to be true?
There’s a guy breaking into his house 😢
Doesn’t this sound a bit like an eating disorder? I’m surprised to hear two doctors calmly advocating not eating for 22 hours every day
It doesn’t. An eating disorder would involve not eating at all.
Most of humane history has us eating lots then eating little. Depending on what we kill or forage.
@@co36 firstly, you’re incredibly misinformed about eating disorders. Secondly, in the days that we used to kill and forage our own food, our life expectancies were a lot shorter than they are now, when most people are able to eat at regular intervals throughout the day.
Then what about 2500 calories required to men.
I live to eat.
I can’t be the only one 😂
Yes brother 😭
me too. and I love to cook!!
