3 simple things you must do to stop the aging clock

The dose makes the poison.

In large doses, a stressor can kill you. In low doses, it can make you stronger. The specific adaptation that a cell derives from being exposed to a low dose of some stressor is called hormesis. And this concept is central to understanding aging.

Because if cells – for whatever reason – lack what they need, autophagy sets in and they often survive. Autophagy or ‘self-eating’ is the process through which a cell recycles its own intercellular junk and damaged organelles in order to get the building blocks it needs to continue living. Unfortunately, the ability of a cell to undergo autophagy in response to stress declines with age. That is why you must avoid the buildup of intracellular junk as much as possible and if possible, train the ability to undergo autophagy.And this is exactly what you will learn from this blog post.

Here are 3 simple things you must do to initiate autophagy and stop the aging clock:

  • Get off the couch and do some exercise.

I admit I am not a sports buff. Worse than this, I hated sport during my school years because it took me away from reading books and frankly, I found it boring and useless. Things only began to change once I learned how to swim at the mathusalemic age of 25. I now swim 1-2 times per week and I still view it as the best sport ever. I used to ride a bike during my college years, but Bucharest is not a bike-friendly place so I ended up giving away my bike and renting one out when I’m in the mood for it.

But after reading ‘Stop the clock – the optimal anti-aging strategy‘ by P.D. Mangan, I realized that I was doing it all wrong. When compared to aerobic exercise, weightlifting and high-intensity exercise training are better options to stress the body and induce autophagy. Of course, this won’t make me give up swimming, but now I won’t hesitate to catch the subway if the situation calls for it. And the subway always seems to be arriving when it’s too late for me to catch it. Murphy’s law.

  • Take a break from eating.

I wish all mothers of grown-up kids would read this. Skipping eating for more than the usual 8-hour night fast is not the end of the world. It won’t kill you. Better still, fasting will activate autophagy. As your cells sense they lack nutrients, they will start recycling whatever intracellular junk you accumulated. In ‘Stop the clock – the optimal anti-aging strategy‘, the author recommends fasts of 12-16 hours including the 8-hour fast. That could be achieved by skipping breakfast and dinner from time to time. And in my case, that’s often what I do during hectic days.

  • Eat mostly plants

Plants are literally rooted in the ground, so the only way they can protect themselves from being eaten is chemical warfare. They can’t shade themselves from the sun and they can’t run away to save their lives – like animals do – so they synthesize all sorts of toxins and pigments. This may be the reason for their purported health benefits. Personally, I never really liked meat – until I discovered sushi during college – , but I’ve always loved colors; a plate full of veggies and/or fruits looks so beautiful. It’s nice to know that having an eye for color turns out to be another simple way to initiate autophagy. And many phytochemicals – like anthocyanins, resveratrol, curcumin – can be ingested from veggies, fruits, herbs, tea, coffee, chocolate (the real one!) and/or dietary supplements. 

And while I wholeheartedly agree with most of the advice given in ‘Stop the clock – the optimal anti-aging strategy‘, I don’t condone the low-carb paleo diet as being efficient on the long term. The moment you’ll lower your carbs, you will by default ingest more fats and more protein. And the body can definitely use fats and proteins to get you some energy, but it takes time to mostly complete your glycogen stores. Not to mention that half of the effect of calorie restriction is protein – or more exactly methionine – restriction. Paleo diets with no sugar, grains or oils sound very good in theory, but in practice people will replace them with lots of daily animal products. I personally find the paleo diet slows me down – both mentally and physically. I need carbs to move fast and think fast. But if you found success by trying paleo, good for you!

Summing up, the dose makes the poison. And this is true for the 3 simple steps mentioned above too.

  • You want to exercise enough to initiate autophagy in your cells, but more won’t necessarily be better. There is no need for ultramarathon competitions.
  • You may occasionally fast around 12-16 hours, but starvation can kill just as well as gluttony does.
  • And finally, while you don’t want your daily plate to miss veggies, consuming a 100% vegan diet will do you no good. Keep your diet varied – that includes animal products too.

Most life extension animal studies stressed those animals at a bearable limit  by using all sorts of stressors: calorie restriction, cold, toxins and many others. And the common denominator in all these studies is the inhibition of growth which is a positive thing after the maturity stage has been achieved.

Nevertheless, species in the wild often adapt to nutrient-poor, water-poor and oxygen-poor environments by varying the age at which maturation takes place and by varying the degree of necessary maturation. In other words, such species may either delay their maturation age (the tiny Arctica islandica clam needs 10 years to become an adult) or they may undergo reproductive system maturation only. The latter is the case of neotenic amphibians that forgo the costly metamorphosis and preserve their youthful appearance (the Proteus anguinus olm). These are evolutionarily conserved mechanisms that inhibit growth and cell division stimulating hormones like insulin and thyroid hormones.

But since most of you reading this post already finished growing up, the lesson is simple: comfort is your enemy.

What is your legacy? 101 ideas on getting started to create and build one

Have you ever noticed the process of metamorphosis in a butterfly? Getting out of its chrysalis is difficult and painful. You may think you're doing it a service by cutting the upper part of its chrysalis to ease its access out of it. But if you'll do that, the butterfly won't have its wings well developed and it will be crippled for the rest of its life. Struggles and challenges are necessary for metamorphosis to take place. They are necessary for creating and building a legacy too.

Mangia di meno, vivi di più – guida pratica alla restrizione calorica con nutrizione ottimale

Mangia di meno, vivi di più – guida pratica alla restrizione calorica con nutrizione ottimale

Al terzo anno di medicina mi sono imbattuta in un articolo in Rete che parlava della restrizione delle calorie con nutrizione ottimale. Si parlava di un intervento apparentemente semplice, fatto sul regime alimentare di alcuni organismi e animali da laboratorio che ne aveva prolungato le aspettative di vita media e massima: lieviti, moscerini della frutta, vermi, topi. Ad essere sincera, avevo liquidato l’esperimento come una stranezza: poteva anche aver avuto efficacia su organismi semplici come i moscerini della frutta, ma non avrebbe mai funzionato su esseri viventi complessi come noi: troppo bello per essere vero.
Il tempo mi ha dato torto: leggere teorie legate all’invecchiamento è una cosa, prendersi cura tutti i giorni di persone che hanno tre o quattro volte la tua età è un’altra. Così, ho semplicemente fatto due più due.Avevo notato che alcune delle persone delle quali mi occupavo quotidianamente erano invecchiate “come un buon vino”, altre come “vino divenuto aceto”. Basandomi sulla loro esile struttura fisica e sui dettagli della loro vita, sembrava proprio che l’assunzione di calorie c’entrasse in qualche modo. È stato così che ho iniziato a scrivere le prime righe di questo libro.

Les différences de vieillissement entre les espèces

Quels sont les mécanismes à la base des différences de vieillissement entre les espèces ? J’ai intentionnellement choisi de répondre à cette question dans un langage accessible à tous. La recherche sur le vieillissement est bien trop importante pour être occultée par un jargon scientifique formel. Cet ouvrage n’aurait pas vu le jour sans l’existence du thé vert, des bibliothèques et d’Internet. Le volume de données que j’ai dû éplucher pour répondre à cette question est énorme. Pourtant cet ouvrage n’est pas exhaustif. Il ne s’agit pas d’un manuel académique ennuyeux.

Jy mag dink jy doen die skoenlapper ‘n guns as jy die kokon se boonste deel oop knip sodat dit makliker kan uitkom, maar as jy dit doen sal die skoenlapper se vlerke nie behoorlik ontwikkel nie en dit sal kruppel wees vir die res van sy lewe.

Eet Minder Leef Langer – ‘n Gids Vir Kalorie Beperking Met Optimale Voeding

Eet Minder Leef Langer – ‘n Gids Vir Kalorie Beperking Met Optimale Voeding

Tydens my derde jaar in die mediese skool, het ek op ‘n aanlyn artikel afgekom oor kalorie beperking met optimale voeding. Ek het gelees oor ‘n oënskynlik eenvoudige dieët ingryping wat die gemiddelde en maksimale lewensduur van laboratorium diere soos gis, vrugte vlieë, wurms en muise verleng het. Op daardie tydstip was ek nie bewus dat sulke eksperimente reeds gedoen word op nie-menslike primate ook nie.

Eerlikwaar, ek het afgemaak as nuuskierigheid, ‘n ingryping wat ‘n effek het op eenvoudige organismes soos vrugte vlieë, maar wat nooit op sulke komplekse wesens soos ons sal werk nie. Dit was net te goed om waar te wees.

Tyd het verby gegaan en my verkeerd bewys. Gegewe ‘n vroeë kindertyd fassinasie met die grense van lewens verlenging, het ek ingenieurswese en medisyne gestudeer in ‘n poging om radikale verlengde menslike lewensduur te bewerkstellig. Na ‘n kort rukkie van navorsing oor neurale prostese in ‘n Duitse laboratorium, het ek besef dat kunsmatig ingeplante toestelle binne in die menslike liggaam nie ‘n lang termyn oplossing was nie.

Ek het huis toe gekom waar ek met my mediese residensie in geriatries begin het, die tak van medisyne wat spesialiseer in ouderdom-geassosieerde siektes. ‘n Snaakse ding het toe gebeur. Om te lees oor teorieë van oud word is een ding. Daaglikse sorg vir mense 3 – 4 keer jou ouderdom is totaal ‘n ander ding en ek het begin om die kolletjies te verbind.

Ek het opgelet dat sommige mense verouder soos wyn en ander soos asyn. Volgens hulle maer liggaamstrukture en gedetailleerde lewens stories, het dit gelyk asof kalorie inname iets daarmee te doen gehad het. Dis hoe ek die eerste woorde van hierdie boek begin tik het.

Mangez moins, vivez plus Votre guide pratique vers la restriction calorique avec nutrition optimale

Mangez moins, vivez plus Votre guide pratique vers la restriction calorique avec nutrition optimale

Lors de ma troisième année de médecine, je suis tombée sur un article en ligne traitant de la restriction calorique avec nutrition optimale. Il contenait des informations sur un régime simple capable de prolonger la durée de vie moyenne et maximale de sujets de laboratoire tels que des levures, des mouches drosophiles, des vers et des souris. Lorsque j’ai lu cet article, j’ignorais que de telles expériences étaient menées également sur des primates.

Pour être honnête, j’ai vu cette intervention comme une simple anecdote qui pourrait avoir quelques effets sur des organismes simples tels que des moches drosophiles, mais également comme quelque chose qui ne pourrait jamais fonctionner pour des organismes complexes comme nous. Cela paraissait trop beau pour être vrai.

Avec le temps, je me suis rendue compte que j’avais tort. Pour satisfaire ma fascination d’enfant sur les limites de l’extension de la vie, j’ai étudié l’ingénierie et la médecine, pour tenter de trouver un moyen d’allonger la durée de vie des êtres humains. Après un court séjour dans le domaine des prothèses neuronales dans un laboratoire allemand, j’ai réalisé que l’implantation d’appareils artificiels dans le corps humain n’était pas une solution pérenne.

Je suis retournée chez moi et j’ai entamé mon internat en médecine gériatrique, la branche de la médecine spécialisée dans les maladies liées à l’âge. C’est là qu’un événement cocasse s’est produit. Lire les différentes théories sur le vieillissement est une chose. Mais s’occuper de personnes trois à quatre fois plus âgées que vous en est une autre, et c’est là que j’ai commencé à faire le lien.

J’ai remarqué que certaines personnes vieillissaient comme un bon vin, tandis que d’autres connaissaient un vieillissement plus proche de celui du vinaigre. Leurs corps fragiles et leurs histoires de vie détaillées semblaient indiquer que l’apport calorique y était pour quelque chose. C’est ce qui m’a poussé à écrire les premiers mots de ce livre.

Coma Menos, Viva Mais – seu guia prático para restrição calórica com nutrição ótima

Coma Menos, Viva Mais – seu guia prático para restrição calórica com nutrição ótima

Durante meu terceiro ano na faculdade de medicina, me deparei com um artigo online sobre restrição calórica por meio da nutrição ótima. Eu li sobre uma intervenção alimentar aparentemente simples que prolongou a vida média e máxima de animais em laboratório, como levedura, moscas de frutas, vermes e ratos. Naquela época, eu não sabia que tais experimentos também já eram realizados em primatas não humanos.

Honestamente, acabei descartando isso como curiosidade. Uma intervenção que poderia ter algum efeito em organismos simples, como moscas de frutas, mas algo que nunca funcionaria em seres complexos como nós. Parecia bom demais para ser verdade.

O tempo passou e mostrou que estava errada. Dado um fascínio da infância com os limites da extensão da vida, estudei engenharia e medicina na tentativa de prolongar radicalmente a expectativa de vida humana. Após um curto período de pesquisa com próteses neurais em um laboratório alemão, percebi que implantar dispositivos artificiais no corpo humano não era uma solução para longo prazo.

Voltei para casa, onde comecei minha residência médica em geriatria, a área da medicina especializada em doenças associadas à idade. Algo engraçado acabou acontecendo. Ler sobre as teorias do envelhecimento é uma coisa. Cuidar diariamente de pessoas com 3 ou 4 vezes a sua idade, é outra completamente diferente e eu comecei a ligar os pontos.

Eu notei que algumas pessoas envelheciam como vinho e outras envelheciam como vinagre. De acordo com seus corpos magros e históricos detalhados, parecia que a ingestão de calorias tinha algo a ver com isso. Foi assim que comecei a digitar as primeiras palavras deste livro.

Veroudering is een puzzel die opgelost kan worden. Welke mechanismen staan aan de basis van deze ongelijkheid in veroudering tussen soorten? Ik heb er opzettelijk voor gekozen het antwoord op deze vraag in eenvoudige taal te formuleren. Onderzoek naar veroudering is te belangrijk om te verhullen met formeel wetenschappelijk jargon. Dit boek zou niet hebben bestaan zonder de uitvinding van groene thee, bibliotheken en het internet. De hoeveelheid data die ik heb doorgespit om de essentiële patronen te achterhalen is immens. Toch is dit boek niet uitputtend. Het is geen droog academisch handboek. Ik heb geprobeerd een onderwerp levendig te maken dat ontzettend belangrijk is voor het verlengen van het menselijke leven. Jij alleen kunt bepalen of ik hierin geslaagd ben.

Avete mai prestato attenzione al processo di metamorfosi di una farfalla? L’uscita dalla crisalide è un momento difficile e doloso. Potreste pensare di farle un favore tagliandone la parte superiore per agevolare la sua fuoriuscita da essa, ma se lo farete, le ali della farfalla non si svilupperanno propriamente e resterà menomata per il resto della sua vita. Sfide e sacrifici sono necessari perché la metamorfosi abbia luogo e sono allo stesso modo necessari anche per creare e costruire un’eredità.

  1. Hey, Anca.

    > consuming a 100% vegan diet will do you no good
    What do you think are dangers of vegan diet? Are animal products one of those bad things, which may cause body to create some positive adaptation too?

    1. Hi Kerlon,
      I wasn’t actually referring to animal products as inducing any type of specific adaptation. The reason for which veganism is bad on the long term is that it limits the variety of your diet. And while we can get many nutrients from plants, we can’t get vitamin B12 from them. This is why vegans are advised to supplement their diet with B12.
      But the bigger problem is that there may be other nutrients that are found in animals only that we have no idea of. And by excluding animal products you may deprive yourself of essential nutrients. In the case of children or pregnant/breastfeeding women, those effects might be irreversible.

      For maximum longevity, I think that the diet has to be as varied as possible and if possible, low in calories. Nutrition is an inexact science with so many variables: the growth conditions of what you eat, the seeds’ quality, the amount of sunshine, your specific genetics, the way you absorb nutrients and many others. This is why variety is the best hedge.

  2. What about ketogenic diet? You have mentioned above on Paleo diets. But, ketogenic diet take it a step further by avoiding all grains & promoting fat from dairy & meat. The followers of this diet claim that once you body reaches ketosis condition, the cells revitalises itself and thus contributing to longevity. Can I know your opinion on this matter. Thanks

    1. Hi Patrick,
      The ketogenic diet is an extreme form of paleo. And except for severe epilepsy, I don’t recommend it on a day-to-day basis. It takes less time to induce autophagy by fasting compared to consuming no carbs at all. I doubt whether someone can function adequately on ketones only – by this, I understand an adult who has a moderately difficult profession and kids to care at home.

      Besides, there is the added problem of what kind of fat to consume. Apart from the fact that different fatty acids have different peroxidation rates, it is difficult to consume fats in a raw state to avoid further peroxidation and any Maillard reaction secondary products.

      I can understand the avoidance of sugar, but I can’t understand the avoidance of carbs. If you provide the body nothing but fats and protein, the body will get its carb fix from those. This is what it does during starvation to survive. In this case, fats are broken into glycerol and fatty acids, with glycerol further being transformed into glucose by the liver. And proteins are broken into amino acids, a part of which can be used as glucose through gluconeogenesis. While a little bit of stress is good to induce adaptation, too much stress causes irreversible damage and starvation is one such example. Ketosis is an artificial form of starvation where you deprive the body – and the neurons! – of glucose.

      1. Hi Anca, thanks for the insight. My objective is to generate a greater amount of autophagy in my body for longevity and better neuron connectivity in the brain to make me smarter. I currently practice IF 7 days a week with average of 18 fasting & 6 hours feasting. Is this sufficient to maximize autophagy production?

        I also read about work of Dr Valter Longo (University of Southern California (USC)who is advocating longer liquid fasting for a period of 3-5 days for cell rejuvenation, cancer & heart attack prevention.This type of fasting need only be undertaken every 3-4 months in a year for a 3-5 days period.Therefore, is my current IF sufficient or do I need to undertake a longer fasting period as advocated by Dr Valter Longo ?

        1. What you are doing is already plenty.

          Dr Longo is one of the few people that researched dry fasting. And he may be onto something, but I have my reservations because most clots take place during states of dehydration. I admit I didn’t take my time yet to search for scientific papers on that. But this is what I noticed in the acute cases of strokes and heart attacks I’ve seen in the clinic. Besides, the more you age, the more prone to clotting your blood will be and the more impaired the thirst instinct will become. And this is why low-dose aspirin is so efficient in preventing these types of things. So wrapping things up, you are already doing the maximum amount of IF and there is no need to add dry fasting with so many unknowns.

          1. Hi Anca, one correction though. It is not completely a dry fast but water fast with occasionally coffee,tea and even soups (below 50 calories per day) to ensure that you’re hydrated. Hence, would blood clot still be a concern ?

          2. No, blood clots wouldn’t be a concern. But you’d still have some calories from soups, so I doubt it is really a fast. By fasting, I understand a way to stop ingestion of any type of nutrients.
