Art’s talk and his life is about honoring and mimicking a form of the diet and physical activities of our ancient, Paleo, past. That may be why he is called the Godfather of Paleo or a patriarch of Paleo (NY Times, London Times, La Stampa, LA Times). He may be the oldest living practitioner of the Paleo lifestyle at the age of 85 and 50 years of “living Paleo.” Social media pundits have prematurely announced his death many times. But, at a lean, muscular weight of 195 pounds and 8 percent body fat, he is rarely sick and is not going to die for a long, long time. His talk will focus on the simple implementation of his healthy, modern Paleo diet and exercise -it will be a “how to do it’’ talk with a sketch of the physiology that provides a foundation for each element, with an emphasis on the brain-body connection to health and longevity. As is well-known, and often confused by critics of Paleo, “Nothing in biology makes sense unless seen through the eye of evolution.”
Hey...it was me (Doug McGuff) who adopted (with credit given) you concept of physiologic headroom, not Stuart McGill. Great talk!! You are looking fantastic. Thanks for blazing this trail.
Doug, yes it was you. I always knew it was you. I have no idea why I said McGill. Sorry.
There's a guy who I wish was still active online! missed his insight during the crazy last few years.
Thank you for producing and sharing these videos for public consumption! The information is fantastic.
Super information-life saving. I'm 80 and following this lifestyle. Most of my peer group are dead or are in nursing homes. This information is unavailable in our present medical system. I also like his
meant to add I like his personal comments relating to his health. It ain't bragging if you can do it. He walks the talk.
@@richardwebster1300 wow , you too are an inspiration
Medical industry is tribal controlled, meant to provide sickcare "treatments" to wreck your body, not cure.
"What's the fast twitch phenotype? When you cut a turkey open the white meat is fast twitch, the dark meat is slow twitch. The meat is dark because the mitochondria gives it that color. The slow twitch fiber stays small because it needs to be perforated (perfused) by blood and oxygen. Slow twitch fibers use oxygen intensively; that is, the mitochondria in the cell uses oxygen a great deal. A large muscle is more difficult to energize. Only the fast twitch fibers tend to get larger if you work out. The slow twitch fibers are physiologically not designed to be large because they have to be perfused. You can't be a fast, strong person without having a sufficient amount of fast twitch fiber. I'm a fast twitch phenotype. Not that I'm that big anymore, but I'm not a little shrinking 85 year old guy either, and I'm very strong. You keep your strength, you keep your lean muscle mass, and you don't get sarcopenia. You know what that [sarcopenia] is -- it is the loss of muscle fibers as you age; they are predominantly fast twitch fibers that you lose. They are the fibers that make you strong and quick. If you need to catch your balance, it's fast twitch that you rely upon because they act quickly. The other part of it is that they [fast twitch fibers] make you live longer than the slow twitch fibers. People who die have almost no fast twitch fibers left and a lot of their brain tissue is gone too. That's because the relationship between the fast twitch muscle fiber and brain mass is very substantial. Why? Well, your fast twitch fibers make sure you don't become insulin resistant and progress into diabetes. They use glucose as a primary fuel. What do they give off as a result? Lactate. What's lactate? It's the number one brain fuel. It [lactate] used to be thought of as a waste metabolite. Now they understand that lactate is fuel for the brain. It isn't used to the extent that glucose is because glucose has biochemicals in it that can create structures like ribosomes and DNA and chromosomes and so forth. The glucose is there not only for the energy but also for the substrate it provides to build things. The number one problem is that you become insulin resistant. The brain is designed to live on glucose, but not the kind of glucose we have available now. The amounts of glucose that we have is far beyond the dreams of any hunter gather. They might come across honey but that would be about it, and they take great danger as African bees are not the nicest bees. So glucose is a primary substrate for the brain and it's a primary energy for the brain. You have all these alternative fuels that can come into play. A lot of people are looking at ketosis now as a way of providing ketones for the brain. You can get ketones from lots of sources. You've got about 133 different types of cells in the brain. A broad diversity of cells, not just the ones we used to understand, like the neurons and the astrocytes and maybe the glial. It [the brain] really only evolved into this modern form in the last 25,000 years. You can look at brain scans and endocasts and a variety of information sources and it's now pretty much accepted."
I am delighted to see you on RUclips again. Long may you run!
Long may he lift and pull and push you mean.😊
@@resistapathy LOL. Yes. And do wind sprints. Do you remember the picture of him sprinting in his 60"s? The line, "Long may you run" is from a rock and roll song. It refers to wishing a friend success and endurance.
I was wondering where he went. I knew Professor Devany likes to periodically pop into ihmc, so I googled that and here he is!
Thanks for sharing. I live Art’s system everyday. Got my 20 year old body back. Im 49. Thank you Art De Vany. My mentor, even though you don’t know me.
I got the impression from Art's videos a while back that he would correct his old book on many points.
wished he would have talked more about his workout as well. He was experimenting with lifting weights with his method but doing it every day. He went dark shortly after, and never followed up.
I would have loved to him to scratch on his diet at least once. All he said, "I love my protein."
U tube three comments
It shows only ONE.
Great fantastic information.
Still waiting for my doctor to say similar.
Not holding my breath!
Today it's politics rather than health.
All the very best in health and prosperity
SORRY... I was wrong; he does give a few statements on diet.
I have a one problem with the statement that you can high sky high insulin and a normal or low blood sugar. The converse is true if you have the T allele for TCF7L2. I have a fasting basel insulin of 3.5 and have had sky high blood sugars. I don’t have type 1. I had that same basel fasting insulin in 2017. My A1c fluctuates between 5.1 and 5.5 eating low carb. With a healthy diet including more carbs plus exercise, my A1c was 5.9 13 years ago.
Hi, I wish I understood what you wrote🙈
@@viktoriyakmassage what part would you like me to explain? Probably my explanation would only be relevant to those with type 2 diabetes in their family.
@@resistapathy no worries. It’s not just one part - it’s the whole thing you wrote🤣 I’ve no idea what those words and numbers are.
I’m fat but all bloods are normal.. No pre diabetes even. Can’t lose the fat 😩 Eat too much! No willpower!
I'm sure the content is interesting but the presentation nearly sent me to sleep. I would have liked to be able to download the dialogue!
No way is he 8% body fat
Hmmm.. Not sure what to think.. If he was 105 - I’d be happy to say, yes, it must be working whatever you’re doing. But I know many 85 y/olds who look and sound way better - who don’t follow any particular diets or workout plans.🤨
I think it is disingenuous he doesn't have at least a few minutes of info/update on diet recommendations ... that was always a big thing with him.
BS that the lecture ends without delivering the advice! AGAIN!
Nice interesting content . Self centered, full off himself presentation is a major turnoff.
He walks his talk. He was born in 1937. May you and I be that healthy and knowledgeable at that age.
I’ve read tons of people in the ancestral health sphere since 2009. De Vany’s advice has held up the longest. Be vain and live long.
At 85 he blows away many 40 year olds…..it’s amazing. I would be proud and want to share, too.
I strongly disagree with your characterization “full of himself”. That’s just misplaced. I, for one, am interested in Art’s current physical condition, because it’s a testimony to his lifestyle. And, I really want to know, as do many that have adopted his Paleo lifestyle. He didn’t come across as overly self centered, just factual. If anything, he comes across as a generous person to share his knowledge. Thank you Art, for your willingness to share!
LOL. Art does always come off as a bit full of himself. But, we all have our shortcomings. Art's info and content are always great. I'm glad to see this presentation. I was concerned he may have "retired" from presenting.
I couldn't watch more than a few minutes of this
Some pretty wild statements not backed up data.
A statistician giving health advice, because 'it worked for him'
Please stop giving this guy a platform; get someone else on instead
