Thank you both, I’ve been waiting for more clarifications regarding autophagy. If I may ask. I think you only gave an example on certain cancers and treatments where increasing autophagy would be negative. However, you mentioned there were many instances where it would have a negative effect. I would be happy if some more examples could be provided. I’m a type 1 diabetic who had a enormous insulin resistance. I started against my doctors recommendation with ketogenic diet and then intermittent fasting and had enormous results the in first year, now 4 years later I’m not having the same results. Anything I or other should be concerned about regarding inducing autophagy through fasting. Thank you again to both of you.

It is unfortunate to see other RU-vidrs preach autophagy with such levels of certainty. Sadly, those who preach projecting ultimate authority on a subject are looked at as trusted sources while those who admit that certainty is not yet apparent are viewed with skepticism. People only want easy answers.

@tracymullane8818 8 месяцев назад

What do you mean? Do you mean that autophagy is not essential and it's too bad that RU-vidrs are saying that it is? Because Nicolas Verhoeven just said that it was necessary for the natural protein cleanup system in the body and when you distill the logic it's pretty self-evident. Of course Nicolas has more of a micro view of things. It's his job to be cautious with evidence. But from the 10,000 foot view starting and stopping metabolic processes in the body is not that difficult- by stopping food and continuing high metabolism through body demands via exercise.

@cristiewentz8586 6 месяцев назад

My feed has been interesting lately. Drs who claim autophagy, done properly, will consume loose skin from weight loss completely and no surgery will be needed. That autophagy from multi day fasts will completely prevent cancer by consuming all damaged cells in your body. That the proponent looks so young due to the elixir of autophagy. The faith healers exist in many religions. And it's perfect: if your own autophagy experiences don't bring these results, it's obvious you just werent doing it in the correct manner. 🙄

Hey Dr. Gill, Kudos on the fantastic content! I stumbled upon your RU-vid channel during my quest to tackle pre-diabetes through healthier eating. Over the past two months, I've immersed myself in over 30 to 50 hours of podcasts from various experts, and your scientific approach on topics like diet, nutrition, and fasting truly stands out. I am a fan. With intermittent fasting and a low-carb diet, I managed to shed around 15 kgs. However, I am still trying to find more information and settle down with a sustainable diet that I can carry for the rest of my life. While devouring your videos, I couldn't help but wish for an audio podcast version on platforms like Spotify. It would be incredibly convenient for folks like me who love listening while working.

@drott150 9 месяцев назад

Fantastic intro into autophagy. After hearing the very nuanced story of what is currently known and not known today about autophagy, I'm realizing actionable intelligence based on specific scientific data is not possible - yet (as Nicolas alluded to). So, I find myself falling back onto the evolutionary model of what's most likely to be at least somewhat helpful with little/no evidence it is harmful. That being our ancestors very often had to go days (and sometimes longer) without eating. Or they ate very little within that same timeframe. Their food supplies were not reliable as clockwork as they are today. Food was available sporadically and at unpredictable intervals. To me this strongly suggests we have biological mechanisms fine-tuned via millennia of natural selection for intermittent fasting (i.e. starvation). I may not understand those mechanisms and there are few scientific papers on them yet, but they *must* exist because that environmental reality forced them into existence over countless generations going back to our prehuman ancestors (and even further back into our ancestral species lineage). So acting on that hunch, I think it wise to recreate or really to conform to that evolutionary process that sculpted our genes and physiology. I think we are likely to discover in the future an organism "fitted" into its environment (and behavior) its ancestors evolved from promotes optimum longevity for obvious reasons. An interesting flipside to the benefits of intermittent fasting (wrt to its evolutionary origins) would be intermittent gorging. Our ancestors, and pretty much all other living organisms, gorge when a windfall of food is unexpectedly made available. Obviously gorging is a problem the west has today in spades, but it must play a role in the modulation of fasting related autophagy. Adding it to the research mix and oscillating back and forth may be a fruitful topic to explore in the future.

@loganmedia1142 9 месяцев назад

If it is true that ancient humans regularly had food shortages it suggests to me only that humans perhaps have adaptations that allow them to survive sufficiently to procreate. Repeated lack of food could still be harmful to both adults and children. In fact we're likely to have many adaptations that allowed humans to not die long enough to make children and enough children so that some of them survived long enough to repeat the cycle. Any or all of those adaptations could have long-term negative consequences. Then there is the fact that evidence suggests that ancient humans typically did not regularly have to go without food.

@limitisillusion7 9 месяцев назад

My intuition tells me that not all autophagy is built the same. The exact cells that are being targeted probably vary between different types of exercise, fasting, smoking etc. Would definitely need tons more research to go into that detail.

@netional5154 9 месяцев назад

In this interview oxidative stress is seen as one of the drivers of reduced autophagy when aging. With respect to the gene deterioration part: David Sinclair (longevity expert) claims that this is more due to the epigenome being distorted by mistakes of proteins acting on it and that oxidative stress does not really play a big role. One of the hopes of his research is to be able to restore the epigenome to it’s youthful state. Perhaps this might then also resurrect autophagy capabilities.

Regarding autophagy in mice and men, what one should consider is that a one-day fast in a mouse corresponds to at least a fourteen-day fast in a man. If people see very interesting results in mice and try to replicate those in men using the same timespan, instead of the "equivalent" timespan, they are bound to fail. By the same token, when Valter Longo has extraordinary results in mice coupling fast (one day) and chemotherapy, then he cannot have (and hasn't) the same extraordinary result in men, coupling one-day fast and chemotherapy. The best results he gets and describes in his book are always with people doing long-term fasts (one week or more) and then beginning chemotherapy while maintaining the fast. On the other hand, clinical studies in humans are at the moment impossible to make properly in this matter because, in the present cultural situation, people are so scared to fast for more than one day that Valter Longo describes how even people in serious clinical conditions refuse to fast because they are afraid to die (!).

@uffa00001 8 месяцев назад

I read a couple of books, by Salvatore Simeone and by Roia Melelli, two therapists specializing in therapeutic fasting, and they describe the entire sequence: first (first day or so) it's mostly glycogen consumption and a little bit of autophagy, then you have one day or so of autophagy - you see that also by the fact that your glycogen is over, but your blood glucose goes up - then autophagy tapers down and goes to a minimum and ketosis begins, and at the fourth day or so one is in full ketosis, and the autophagy lasts during the entire fast but it's at its highest during the second day. I gave it for granted that this is common knowledge, not something to mumble about. They actually say that a long fast is better for certain purposes (such as losing weight) rather than many shorter fasts because when one fasts, one goes through the entire process any time: prevalence of glycogen burning, prevalence of autophagy (proteolysis), and prevalence of fat burning, so you have the first two-three days when you are not really in ketosis each time you start a new fast. The body always first replenishes the glycogen reserves after a fast, so one never starts a fast without burning the glycogen reserves first, although there always is a small amount of the all three mechanisms (glycogen tapping, proteolysis and lipolysis) in the body during the fast.

@patedwards8844 8 месяцев назад

I'm doing OMAD. Would that be considered short fasting regarding your comment?

@uffa00001 8 месяцев назад

@@patedwards8844 OMAD is not even fasting "in my book". It is certainly beneficial, because during those hours in which we don't eat there is a small amount of autophagy and "cleansing", but for what I understand what happens is that everyday you (try to) reconstitute your glycogen reserves and the body is mainly nourished through glucose. Little ketosis, and little autophagy, but that little is every day, 365 times a year, so in the long run it helps a lot. If I did OMAD I would buy a glucose meter and a blood ketone meter to see what happens in my body, i.e. if I am in ketosis during part of the day or not. It is entirely possible, especially if the OMAD is of ketogenic style, that you enter ketosis and remain in ketosis all along, which also means that there is a state of autophagy, which is always present in the human body, but is enhanced in the state of ketosis (and even more in the state of ketosis due to real fasting). OMAD makes you lose weight if you are in a caloric deficit, which is not necessarily the case, because one could eat once a day, and eat for the entire caloric need. Yet, I think it is easy to lose some weight while doing OMAD, i.e. I think it is easy to maintain a constant small caloric deficit. OMAD should, in theory, easily lead to ketosis IF the one meal is ketogenic, and being in ketosis favours the loss of weight.

Of course there is more at play here , like the lowering of MTOR, Insulin and IGF1 levels, but very conclusive human data on this specific form of cancer. The fasting mimicking data from Valter Longo is also becoming more and more convincing and then you have former soviet data on psychological states in humans (referenced in the Arte documentary called the Science of Fasting) I would love to know more of the mechanisms causing different types of Autophagy.

If I were to guess i would say autophagy would increased due to fasting more than spreading out meals at same calorie count. I would assume if the cell had a break from processing energy it would have more energy available for autophagy regardless if it is overall processing the same caloric intake and nutrients count. I would also assume the rate would also vary depending if the cells really needed to do more cleanup

@kestag2110 9 месяцев назад

@CraigHocker 9 месяцев назад

at about 20:00 - it's really not surprising that 17-19 hours has little evidence of a rise, that hardly qualifies as fasting except in the modern world of plenty. And a mouse with it's much higher metabolism, you see autophagy increase in a 24 hour non-feeding period, but that's similar to a human going without food for a week. The 1:1 (day on, day off) intermittent fasting mouse studies that have been frequently done are like taking humans and only allowing them to eat every other week. I've been waiting for that study. ;-) Meanwhile, if you believe Victor Longo's work, it's 4-5 days of water fasting to significantly raise the autophagy rate. And obviously it doesn't keep going up as a normal healthy adult with average body composition can do a 21 day water fast without issues (having a proper refeeding protocol at the end). .

Hospitals, doctors offices and schools should be places where good nutrition is taught and provided not places that contribute to disease and obesity. It is crazy the hospitals are feeding people the very food that caused the heart disease, high blood pressure or cancer that they are treating. Every person in the hospital should receive some nutrition education before being released. Every doctor visit should be an opportunity to educate patients about how food choices impacts their health outcomes. The fact that doctors do not get nutrition training as part of their training makes no sense. Medicare and Medicaid should require nutrition education as part of patient care. Focus should be on food choices. Fasting should be investigated as a treatment for disease.

No need for fast-food, gaming or hyped social activities as Halloween and so. Acknowledge, learn about the social external hypes, but be in awe with our mighty wonderful self, free from nature.

Brilliant video guys. Look up the follow up care of Japanese POW camp victims on average 600 calories a day. They lived longer with dramatically fewer cases of diabetes cancer and heart disease. At 80 they had bodies of 60 years old men. As a RN I've looked after a few.

How does the result look once you include all the ones that died from their treatment? We'd have to a do a follow-up where we subject people to hard labour and starvation comparing them to people not mistreated, but making sure a similar percentage die in each group. Then we can determine if the hard labour and starvation had the claimed long term benefits.
