Dr. Steve Horvath on epigenetic aging to predict healthspan: the DNA PhenoAge and GrimAge clocks

[@FoundMyFitness]

00:00:34 - The Horvath clock explained: Methylation patterns at unique areas of our DNA involved in gene regulation predict a person's age within four to five years. 00:06:42 - The effect of HEREDITY on the epigenetic clock rate (determines as much as 40 percent of rate). 00:12:48 - How the stability of epigenetic information has potential implications in forensic science. 00:26:08 - How diet, exercise, education, and lifestyle factors effect the epigenetic clock. 00:31:59 - How transplanting young cells into an old body may slow epigenetic aging of the recipient. 00:47:23 - Reprogramming pluripotent stem cells by activating specific genes can reset the epigenetic clock. 00:50:56 - Do epigenetic changes drive aging, or are they the result of aging (just the "face of the clock")? 01:02:32 - How poor sleep speeds up the epigenetic clock. 01:12:12 - *Super silly outro easter egg* This episode has a lot of amazing studies and figures included in the slides, which are available to FoundMyFitness Premium Members, in a convenient presentation!

I don’t really understand when Steve says that a healthy life style doesn’t affect the epigenetic ageing, if that was the case what on earth is David Sinclair doing . I am a tad confused

[@robertwilsoniii2048]

I think he's wrong. He doesn't sound like he fully understands nutrition, for example. He thinks vegetarian is healthier than non vegetarian without specifying if he means vegan and the importance of b12, for example. And he has a category of 'vegetables' rather than specific quantities of micronutrients. Often in the University of California campuses faculty tend to be a little egg headed. 🤷🏻 He was brilliant enough to build the clock, but still doesn't understand nutrition. 🤷🏻 Legend has it Bertrand Russell couldn't figure out how to use a coffee maker. Similar sort of thing.

@@FoundMyFitness Dr. Rhonda Patrick, humans are rapid aging 10 times as fast as our lifespans 13,000 years ago according to historical texts. I found out why in my theory of aging. It's carbon-14. No logical study was EVER done on this. In order to do this, we need the answer to the problem. The answer might be creating a molecule to bind with that radioactive carbon atom to put it in a state where DNA doesn't use it as food and possibly even dispose of it as waste. They recently created pills to do this with radioactive metals. Thank God they did that because it gave me the idea for dealing with carbon-14. I messaged your website detailing further into my theory and how it explains everything related to lifespan variations within the last 13,000 years in history.

If at 16 years old you stored some of your own bone marrow. Could you in fact store it for long periods of time 10-50 years and then inject your own bone marrow 10-50 years later, would it age while stored? Would it eliminate graph vs host issues if it was your own bone marrow? Just curious.

[@jmitteld]

There is a Beijing company doing exactly this. I came across them a couple of years ago in ZhongGuanCun Life Science Park (www.sciencemag.org/advertorials/set-success-introduction-zhongguancun-life-science-park), but I don't have their web address. You can try searching from here: www.zgcgroup.com.cn/zgcadminen/home/index/index.html My personal opinion is that 20 or 30 years from now there will be better rejuvenation options available.

Bone marrow transplant in later life is said to reset the age of the blood but does it affect other organs as well?

[@joedart1465]

Assuming we could store the 16 year old's marrow in a state of suspended animation, that would be a very sensible thing to do in case we discover within the next 10-50 years that our own juvenile cells can regress our elderly cells. I asked one of the prominent ageing scientists (one in mitochondria) this question and if this was something we should be doing anticipating a need for those cells. His response was that cell storage for that long period was the impediment.

[@AVdubs1]

Great interview. We definitely need a follow up with Dr. Horvath in a year or two. It's clear this field is moving _fast_! At 00:27:39, if I'm reading this correctly, it appears that carotenoid consumption has a much greater impact on GrimAge than fruits & vegetables or exercise. Also, reducing C-reactive protein seems to have a profound effect as well. Traditional health advice is focused on diet & exercise, but would it have a bigger impact to increase carotenoid consumption and reduce CRP (through L-Carnitine or curcumin)?

[@sensam6155]

Very close, but it's not technically carotenoid ''consumption'' as much as it is having circulating traces of carotenoids. Of course, one would assume eating more carotenoids would increase circulating traces of carotenoids, but there are other factors at play that can make it a tad more complex than that.

What is the definition of Hispanic used in the study? After all Hispanic is defined linguistically, and it is frecuently a person of European descent? Is it a definition of Hispanic pertaining only to the US or is it a more broad definition of people of Iberian Descent, which would include people in India and the Philippines. Also, how is the relationship between the Horvath clock and the association with a culture, as suggested in the study. After all, there are many Hispanics of Caucasian origin? So, I am very confused by the study, it would tend to imply there is room for improvement in the testing and definition. As it is stated it would appear to be based on some form of classification that lacks substance.

the Horvath clock can hardly be changed by lifestyle interventions?... and yet there is overwhelming evidence that a healthy lifestyle makes people living longer (and healthier). is this not contradictory?

[@shad0ex]

A healthy life style just makes you live to your maximum age. What he is saying is that it will not extend that. An unhealthy lifestyle means you will not reach your maximum age and die before then.

[@dsakurai]

He did mention that this is only in blood. He didn't observe other tissues. So, in blood, at least, exercise makes little difference but exercise does more things like increasing BDNF, increasing ketones, activating sirtuins, etc. which are probably not measured in blood cells.

[@adaarevalo2871]

He did also say that fish oil slows down the aging process the most. He also mentioned a few other interventions that could slow down aging but more research needs to be done in humans to confirm. Both of those statements directly contradict his original statement that the epigenetic age cannot be altered by lifestyle choices. I’m a little confused.

[@factchecker9358]

Another issue is the long list of deficiencies that add up with age and largely go unmeasured in the population. Vitamin D is about the only one of dozens that actually gets measured and studied much. Are we just measuring the combined effects if 20 or so deficiencies in one clock and methylation process?

[@eugeniebreida]

And yet no hormone D measurement in his ‘clock’ data. Curious.

[@Urketadic]

There is research that shows that calorie restriction and fasting increases lifespan. But he is saying that lifestyle changes have effect on epigenetic clock, how does that work?

Thank you, Rhonda, for your added explanatory and elaborative notes. They are a great help to me. But! I can't understand the charts for Young Finns study nor the Vitality 90+study!

Is each stationary over time? What am I missing? If there is NO difference in rate and each dot is stationary over time, then all I see in the charts is the distribution of some unknown number of different subjects who live at a slower or faster DNAm aging.

[@Margics]

Good points. To the sentence “ Double the exercise” is not always good haha it all depends the level of exercise the person is doing and if it fits their requirements. Because exercise is personal. Not one size fits all. Personal trainers are the adequate professionals in charge of prescribing it. Unfortunately everyone talks about exercise incorrectly and ignoring the methods for exercise prescription to produce excellent effects on health and aging.

[@juliahello6673]

An integrative metabolo-epigenetic outlook supports a new model whereby metformin operates as a guardian of cell identity, capable of retarding cellular aging by preventing the loss of the information-theoretic nature of the epigenome. The ultimate anti-aging mechanism of metformin might involve the global preservation of the epigenome architecture, thereby ensuring cell fate commitment and phenotypic outcomes despite the challenging effects of aging noise. Metformin might therefore inspire the development of new gerotherapeutics capable of preserving the epigenome architecture for cell identity.

[@GoalOrientedLifting]

I liked this podcast, but one thing that annoys me about research, is how they put all types of exercise under one umbrella. Cause strength training is vastly different than cardio. And when you look at the elderly population, you see muscle mass or strength as a correlation, to longevity. But you don't see the same with cardio. In cancer treatment, muscle loss is a huge correlate on how well you respond to treatment, and how long you'll live with the cancer. Cardio doesn't do much at all. But for some reason there's is barely any research on lifting and cancer treatment. Even though lifting is more muscle sparring than steroids.

That makes sense to me, if temporary methylation is a defense mechanism targeted at viral DNA. By methylating the viral DNA and the cellular core DNA the virus could be prevented from replicating itself. But you cannot 100% undo this process post-infection, because that would hurt cell specialization (anyone who has ever built a PID controller, knows why). Radiation damage, on the other hand, happens absolutely randomly when a highly energetic particle rips through your tissue. There is no way to prepare for it.

Do you by chance know any good experiments I can do with my diet for educational purposes? I want to put in on my new channel on a health segment. Ive done keto and vegan with great results. Dont mind any diet as long as its not too unhealthy for the before.
