- The concept of Intermittent Fasting seems to be the latest diet fad fueled mostly by laboratory rather than human studies. Investigations suggest an excess of energy intake especially during early and mid-life may be associated with increased mortality. For over 100 years laboratory studies in a wide variety of animal models consistently demonstrate caloric restriction often leads to a dramatic increase in lifespan. The average dietary intake is restricted to about 40% of normal.
Amazingly this added longevity may be accomplished without a total decrease in energy intake. Rather manipulation of meal frequency and meal size may be the key issues with significant inter-individual variation regarding benefits.
Intermittent Fasting fits into the overall category of caloric restriction. Included among the options are calorie restricted eating. Generally this means fasting for 12-20 hours a day and consuming relatively few calories on those days. A popular variant is Intermittent Fasting for 2 days out of the week. Either a complete fast or consuming fewer than 25% of typical calories will suffice. Alternate day fasting is yet another option. Another choice is restricting calories to no more than 30% of normal for 5 consecutive days during the month and repeating the diet 3-4 times each year.
In laboratory investigations these dietary manipulations lower the glucose, insulin and certain growth factors while simultaneously increasing production of ketone bodies in the liver and intestine. Caloric restriction protects against obesity, cardiovascular disease, high blood pressure, diabetes, degeneration of the central nervous system and reduces the incidence of cancer. Animals show improved balance and coordination as well as greater endurance on physical activities such as running.
Caloric restriction in animals improves recovery after surgery, improves mental health and reduces clinical manifestations after spinal cord damage and traumatic brain injury. It decreases age related eye disease and preserves hearing into old age. It may lessen symptoms akin to multiple sclerosis and improves both short term and long term memory.
The mechanisms associated with improved health from caloric restriction are still in their infancy but appear to involve the circadian clock, ketone bodies and their effect on metabolism and even an altered gut microbiome.
I've been on a calorie restricted diet for over 2 years now only eating 800-1000 calories a day tops, along with intermittent fasting of at least 16.5 hours. I went from having cirrhosis in my liver from non alcoholic fatty liver to no fibrosis at all with very mild fatty infiltration in the liver and losing over 45 pounds in less than a year.
This is old I know, and you might jot be doing this anymore. But what about muscle mass with such little calories? For you specifically?
I also have noticed a vast improvement with my fatty liver issue! I have been intermittent fasting for 4 months, and my liver values were in the normal range for the first time in over 10 years
@@kiaharper7172 I wanted to let you know what I have noticed, just in case you are still curious.
Overall I've noticed I am a bit "stringy." All through my school years (in my 40's now) I was a thinner person, never really gaining any muscle mass regardless of what I tried (though never tried steroids). I am noticing that my physic is almost like it was back in high school, but with some fat around the belly still. If I flex, still can't form a bicep, though the musculature is firmer than it was pre-fasting diet.
Good luck with everything!
This man is a walking medical encyclopedia!
I just found this channel and I'm sad to see he's stopped making videos. He's shared so much information. Thank you Dr!
He passed away
@@bartoszbrown1322sad to hear .. such a good doctor 😢
@@bartoszbrown1322 He did? wow sorry to hear. He had such a fountain of knowledge.
I really appreciate your straight forward approach to a wide array of subjects. Thank you, sir.
My autophagy rate increased markedly while watching this video. Exemplary primer on fasting concepts. Kudos.
I just love this man, he has helped me so much
It has changed my life, but I would strongly suggest someone who is going to try it start with a pure KETO diet first for a month so your appetite will be greatly reduced, making it much easier. I now do 20/4 and low carb with 0 added sugar. I am 65 and lost over lost 60 lbs over three years. I feel like I am 30 again. I am sharper and have a ton of energy all day.
1 wholesome meal per day, and a health snack either in the morning or at night,keeps a person optimized
6 years 18/6. Lost weight lowered blood pressure. Coronary calcium score went from 28 to 14.9. Low carb high fat.
It’s all about insulin and insulin resistance
I knew I had an issue got hungrier when I started eating. I m not diabetic but I started testing an hour after meals. Noticed the numbers were much better on higher fat lower carb and much more satiated.
What fast do you eat?
@@microb4538 18 hour fast 6 hour eating window
@@songmansinatra120 sorry i was asking what " fats" ...
This man is pure genius
Thank you for your videos. I enjoy many of your videos. I like that you explain conclusions. I like that you give all the information about a topic as you can give, and it's impressive. I noticed you perhaps touched on the idea of an ancestral diet without mentioning it directly in that outcoms vary, There are secrets to be found in tradition as well. As someone with a few conditions (psychiatric and neurological ), i feel fasting is not for me. Smaller meals are best, if my gut isn't working then i don't have consistancy in mood and thought. I did my own version of the cabbage soup diet (developed for heart surgery patients that need to loose weight) a while back and it gave me some important insights into food as nutrition vs food as calories.. Thank you Doctor.
Fascinating, as always
Agreed
Excellent,but I wish you added links to the studies and sources of information presented in this video.
Thanks
Wherever you are, happy new year. Thank you for sharing your knowledge. Peace. Love. Light. 🎉
There is growing evidence that ketones can actually help "reset" many aspects of the body. I personally find that intermittent fasting dramatically improves my focus.
Calorie restriction without fasting is useless. You just end up tired and hungry,. You body slows down and decides you do not need as much, so you have to double down by cutting more calories. Fasting does not seem to act like that, and if you avoid sweet food and other refiened carbs then you tend not to get hungry at all. He's a bit behind the curve on this issue I think, as he seems to use "calroie restricted" and "time restricted" together.
Well Damm...

Thank you 🙏
Excellent doc..👏
I been doing alternative day fasting for three months now...I'm not hungry...and have lowered my cholesterol by 50 points. Still have a way to go...what is the impact of fasting on cholesterol? Excellent video with latest research. Do you take patience long distance?
I’m thinking only veggie drinks, yogurts and fruits for lunch and snack options.... Tweeted links to several of ya videos! You Rock!
He has passed away for anyone wondering. RIP. His obituary is online.
Sad
I wonder what he died from.😢
This guy is awesome
I am trying both IF and Keto. It isn't easy, had to slowly adapt. Yes I have lost weight. Now I need to slowly ramp up the exercise component. Not sure how I feel but what is surprising is how long I can go without eating and still function.
If you have a couple of lbs of fat anywhere on your body, you need no food. But you have to be adapted to burn fat. IF and low carb is the best and fastest way to achieve that.
This sounds very good but how can you control your craving?
How can you stop thinking about food?
How can you train your body to eat once a day and fast minimum 15 hours?
Thanks for the information, Doctor.
Appreciate you doctor 🙏
That’s great information very good summary of current science on aging diet and aging.
Are there any studies of intermittent fasting for people age over 65
Thank you
This seems like the best change you can make to change your quality of life and is free.
You are right. I have found the same benefits of Intermittent Fasting.
This dude is brilliant.😅
Best doctor in the world 🌎 👏
I wanna like this, but I'm not the one takin' that 666 outta there
Positivity never touch this person,
Fasting is a great way to improve weight loss and insomnia. I've been doing intermittent fasting for almost a year. I drink lots of tea on those days I fast. Would it be okay for someone to take Lithium and fast? I think Lithium needs fatty foods to absorb but not sure if that's true?
Intermittent fasting helps insomnia?
•• I take lithium orotate -
Please do a video on ephedrine, or the combination of ephedrine caffeine and aspirin sometimes used in weight loss in bodybuilding. Thank you.
Great video!😊
Good information!
Speed up the video to 1.25.
Lol, yes I did that as soon as I found this guy's channel. Great info, but gotta speed it up.
Thank you 😊
Last update was over a year ago, this man was bored in lockdown or has been taken out 😁
Interesting
Did he pass away?
If drugs studies can be done (presumably safely) on humans, why studies on fasting can't?
With 2/3 of the US population overweight, I don't think it's due to lack of qualified volunteers.
I think because pharmaceutical companies cannot make a single dollar on it. Big pharma can make money from medications and that's it so that is all they will ever study and invest in. It's the same way that many natural or legacy drugs work for current illnesses, but big pharma pushes for new drugs that they can patent and make billions on. Always follow the money.
Our evolutionary ancestors probably had 1-2 huge meals per week... of entirely meat.
What about brock lesnar 😬
how do u fix dry peely nutsack? IM SERIOUS!!!!
