Yoshinori Osumi's fasting method: the benefits of autophagy for the body


Mechanisms of autography

Osumi has studied the relationship between spiritual practices and fasting for many years.
In the process, he proved that when there is a lack of nutrients, cells begin to self-destruct outdated resources. This is called autophagy. It is the only way to renew cellular structures. The term “autophagy” was introduced into biology back in 1974 before the discovery of Yoshinori Ohsumi.

It was invented by Christian de Duve, who also discovered autophagosomes, a “transport” for delivering cellular structures to lysosomes. The essence of Yoshinori Ohsumi's research is as follows:

  1. The biologist conducted an experiment on mutated fungi that do not have a protein decomposition mechanism.
  2. Yoshinori Ohsumi's autograph showed that only cells that did not receive nutrition did not change. Fungi that were in conditions of food shortage began to accumulate autophagosomes and use the resources they already had.
  3. Yoshinori Ohsumi's discovery is that cells that do not receive nutrients begin to “eat” unnecessary structures within themselves. As a result, during fasting a person does not feel hungry.
  4. Having studied the processes of autophagy in more detail, the Japanese scientist proved that after the access to food is stopped, the fat layer gradually decreases.

Yoshinori Ohsumi: “I never said that fasting promotes autophagy”


Watch the video where the scientist himself clearly talks about this!
Honestly, we are tired of reading articles in the style of “A Japanese man received the Nobel Prize for proving that fasting even cures cancer.” Where do people get this from?

They clearly read not with their eyes, but with some other mysterious places, forgive me.

For almost all articles about fasting, we receive comments in the style of “WHAT DO YOU THINK OSUMI WAS A NOBEL PRIZE FOR?!?!”, “THE AUTHOR KNOWS NOTHING ABOUT AUTOPHAGY, FOR WHICH THEY WAS GIVEN THE NOBEL PRIZE.

And a hundred more similar ones, the meaning is the same.

Let's figure out once and for all why this very doctor was given a bonus.

An indisputable fact: in 2021, Japanese scientist Yoshinori Ohsumi was awarded the Nobel Prize for the discovery and research of the mechanisms of autophagy.

And then some absolutely hasty and erroneous insinuations begin in the style of “THEY HAVE PROVED THAT HUNGER HEALS.”

No, they haven't proven it ! The prize was given not for this, but for the discovery at the genetic level of the most important cellular process (the genes that are responsible for it were found).

The phenomenon of autophagy itself has been known for a long time, back in the 50s of the twentieth century.

Its essence is that in the process of cell growth, some of its components that age must be replaced, and before that destroyed.

Moreover, there is even a video in which the scientist himself says that:

“I never said that the fasting process promotes autophagy, apparently something went wrong. Maybe someday I’ll change my mind, but for now, apparently, there was a mistake.”

We have a very detailed article on autophagy and its myths , here we list the main takeaways you need to know:

  1. The mechanism of autophagy is called self-phagocytosis and it works like this: “hungry” cells use their own proteins as a source of nutrition.

    This is true for both healthy and diseased cells!

    That is, the opposite situation occurs: in case of famine, the destruction of cellular components promotes cell survival, maintaining cellular energy levels.

    Since the work and effect of autophagy have not been fully studied, it cannot be said that this is an unambiguously positive or negative process that is harmful or beneficial to us: it occurs differently in different diseases.

    In some cases, autophagy is a completely positive adaptive response to stress that promotes survival, while in others it contributes to cell death and disease development.

    For example, autophagy plays a really important role in cancer: it can be positive, protecting against cancer and destroying potentially dangerous cells, or negative, helping tumor cells survive .

    Moreover, you must understand that treatment of cancer is a severe blow to all systems of the body!

    After it, you need to recover, but where does a starving man get strength? Fasting is a lot of stress even for a healthy person, what can we say about a sick person?

  2. In fact, autophagy helps our body maintain homeostasis (constancy of the internal environment within one organism) during fasting.

    Those. It is thanks to this process that the body can fast relatively harmlessly for some time, receiving the necessary amino acids from its own tissues.

    This function keeps the body alive during interruptions in food supply.

  3. The fact that one cell has died does not mean that the new one formed in its place will be of better quality and no one can guarantee that it will not be a malignant tumor cell.
  4. Autophagy does not start during fasting; this mechanism never stops working, it is constant.

    There are about 37 trillion cells in the human body, and of these, in the average adult, approximately 220-240 billion die and are replaced by new ones every day. This is approximately 2 million cells per second.

    Different organs have different cell lifespans - the intestines are about 4 days, the skin is 12-20, and so on. By the time you've read this far, about a million cells have been replaced by new ones.

    Those. It is impossible to completely cleanse yourself of all decay products stored in cells. While you (figuratively speaking) cleaned 10,000 of some cells, they formed again in a million others.

    It's like eating so much food that you get full once and for all and stop wanting to eat. This is simply impossible - sooner or later any amount of food will be digested or eliminated with the help of nausea or, excuse me, diarrhea, and hello, hunger.

    Why is everyone connecting fasting and autophagy? Hunger simply activates this process and makes it more accelerated.

    The body, which ceases to have enough nutrition from the outside, begins to use its own resources, i.e. fasting goes through the process of autophagy - therefore (and for many other reasons) during a fast, it is not fat that is lost first.

    You do not need to starve to start autophagy, this is technically not a side process that occurs only during hunger, but one of the main processes in the body, and its disruption is one of the main causes of metabolic disorders .

  5. Metabolic syndrome: a deadly quartet for those 50 and older

  6. There is simply no reliable data about what exactly hunger is, what its productivity is and how it affects the process itself.. Doesn't exist yet. And it is not clear whether they will exist.

    What the scientist himself writes in his article from the official website of the Nobel Prize:

    A better understanding of autophagy promises to help characterize the ambiguous relationships between genetics, phenotype, and disease, especially in identifying the conditions of induction and different modes of autophagy.

    However, autophagy research is still in its early stages, and our understanding of the physiological role of autophagy in particular is only in its infancy.

    The scientist himself, who received the Nobel Prize for autophagy and has been involved in science for 28 years, says that in general, nothing is particularly clear yet.

    And people on the Internet understood everything and wrote 500 articles about the healing power of a hunger strike! Don't you think this is too presumptuous?..

Nutrition is an important part of the treatment of any disease, but not the main one. If everything were so simple, then people would have long been treating oncology, HIV, etc. with fasting.

Alas, you cannot destroy cancer cells just by eating in some special way. Cancer is destroyed by chemotherapy, radiation therapy, hormonal treatment, and immunotherapy.

It is also impossible, for example, with the help of special products to force your thyroid gland to produce the amount of hormones that is needed - there are special medications for this!

Even diabetes research shows that even completely eliminating sugars (carbohydrates) is not a panacea for solving insulin problems!

Nutrition is always a support for the body, but not the main treatment.

We hope we have sufficiently convinced you that fasting does not “break down” your diseases and does not relieve you of them directly, through the destruction of “harmful” cells; this, alas, is an uncontrollable process for us (we hope, only for now).

What is a power window

Ohsumi continued his research into intermittent fasting and its effects on muscles. He arranged “nutrition windows” for them - the time during which a person eats. For example, if a person has breakfast at 7 a.m., then the specified period opens at 8 a.m. If dinner falls at 8–10 p.m., then the window extends to 12–14 hours.

Studies conducted on animals showed that those individuals who periodically fasted felt better, lived longer and were less sick compared to those who ate a normal diet. It is worth noting that both groups received quality products. This means that a small window of nutrition is more beneficial for the body.

Its main properties:

  • reduces the risk of breast cancer;
  • increases UV protection;
  • reduces blood pressure;
  • improves sleep quality;
  • reduces the risk of heart disease.

Benefits of shortening your eating window

Cambridge University Professor David Rubinstein also confirmed the effectiveness of the method. He stated that intermittent eating prevents the development of dementia, Parkinson's and Huntington's disease. According to him, the autophagy mechanism helps the body cope with infectious and inflammatory processes, so a large interval in nutrition is necessary to maintain health.

The narrowing eating window of the Nobel Prize-winning Japanese diet forces the body to lose fat reserves at night. After a person adapts to the regime, uncontrolled appetite disappears, metabolic processes and the amount of energy consumed improve, and the ability to switch from one energy source to another increases.

The benefits of the eating window for weight loss, according to doctors:

  • body weight decreases;
  • the risk of cardiovascular pathologies is reduced;
  • the likelihood of cancer pathologies is reduced;
  • blood pressure is normalized;
  • efficiency increases;
  • sleep becomes deeper and smoother;
  • the body is rejuvenated.

An additional advantage is that a person does not have to deny himself or herself any foods. He eats the same amount and at the same time loses weight.

Fasting patterns

Please note that the Yoshinora Osumi system, or fasting diet, has several variations of intermittent fasting. The main ones are the following:

Fasting scheme Description
16/8 This is an eight-hour eating window, or three meals a day system. This cyclic fasting scheme is the most common. The bottom line is that you need to abstain from food for 16 hours during the day, and organize meals during the remaining 8 hours. Best option:
  • 8 o’clock – breakfast;
  • 12 noon – lunch;
  • 16:00 – dinner.

You can choose another option, the main thing is that there is an interval of 8 hours between extreme meals. The scheme can be followed daily.

14/10 A ten-hour eating window is the most gentle fasting scheme. Meals should be organized within 10 hours:
  • 8 o’clock – breakfast;
  • 11 a.m. – lunch;
  • 14:00 – lunch;
  • 16:00 – afternoon snack;
  • 18:00 – dinner.
20/4 Four-hour eating window:
  • at 8 or 12 o’clock – the first high-calorie meal;
  • At 14:00 or 16:00 – the second high-calorie meal.
24 This is a daily fast from one meal to another, for example, from breakfast to breakfast the next day. It is allowed to carry out 1-2 times weekly.
36 The “every other day” scheme, the essence of which is fasting for 36 hours. The technique involves breakfast at 8 am and refusal to eat until 8 pm the next day.
5/2 For 5 days you need to eat well, and for 2 days off you need to fast or consume no more than 500 kcal.

The principle of fasting according to Osumi

For a greater understanding of physiological patterns, a Japanese biologist proposed the concept of a “nutrition window.” This term refers to the time during which food is consumed. If a person gets up at 6 am and has breakfast an hour later, then his “nutrition window” opens at 7-00. If dinner falls at 22-00, then the “food window” of such a person closes at the specified time and generally lasts 15 hours.

Scientific research has shown that a shorter “eating window” brings much more benefits to the body. At the physiological level, this manifests itself in the following:

  1. Improves the quality of night sleep
  2. Reduces the risk of heart disease
  3. Increases UV protection
  4. Blood pressure normalizes

The merit of Y. Osumi in dietetics is that he proposed the so-called fasting diet. It looks like different versions of intermittent fasting.

Scheme 16/8

This is the most common and popular scheme. The “power window” is 8 hours. That is, a person fasts for 16 hours, then eats as usual for eight hours. Meals at this time should be three times a day, for example:

  • Breakfast - at 8 o'clock.
  • Lunch – at 12 noon.
  • Dinner – at 16:00.

Then a 16-hour abstinence from food is repeated. The cycle repeats daily.

Scheme 14/10

This option is considered the most gentle. The “nutrition window” lasts 10 hours and the diet is divided as follows:

  • Breakfast – 8 hours
  • Second breakfast – 11 a.m.
  • Lunch – 2 p.m.
  • Afternoon snack – 16:00
  • Dinner – 6 p.m.

Scheme 20/4

The “nutrition window” under this scheme is reduced to four hours. The daily diet is divided into two high-calorie meals. Depending on the operating mode, they can be arranged at 8 and 14 o'clock or at 12 and 16 o'clock.

Scheme 24

This fasting option consists of periodic (1-2 times a week) daily fasting. Each abstinence from food continues from breakfast to breakfast. This is not the most severe hunger strike in terms of duration, but it also requires a certain amount of willpower.

Scheme 36

According to this schedule, refusal to eat should last 1.5 days. It begins after breakfast (at 8 am) and continues until a light dinner (at 8 pm) the next day. This fasting more actively triggers the process of autophagy in the cells of the body.

Scheme 5/2

This fasting algorithm includes regular meals for five days and partial fasting for 48 hours. During these two days, fast food or food limited in calories (up to 500 kcal) is allowed.

Rules for intermittent fasting

Please note that until you get used to hunger, you can drink green or lightly brewed black tea without additives. The desire to eat something will be wave-like. As soon as a person drinks water, hunger goes away for several hours. Other rules of the intermittent fasting technique:

  • During fasting, monitor your own sensations.
  • Enlist the support of your loved ones.
  • Drink plenty of water both during abstinence and during your eating window.
  • Come out of fasting gradually - do not overeat the next day after finishing the method.
  • Do not draw conclusions earlier than after a month of regular compliance with the rules.
  • Don't let yourself think about hunger, get busy.

Contraindications

Fasting, even short-term, is not allowed for all categories of patients. Before you start following a technique, you need to study its limitations. Absolute contraindications include:

  • lactation;
  • rickets;
  • exhaustion;
  • anorexia;
  • reduced BMI;
  • open form of tuberculosis;
  • disorders of the kidneys and liver;
  • age less than 18 years;
  • thyrotoxicosis;
  • pregnancy;
  • oncology;
  • diseases of the heart and blood vessels.

Yoshinori Osumi's fasting method also has relative contraindications. These require a separate consultation with a doctor. Such restrictions include:

  • gout;
  • diabetes;
  • taking medications regularly, including oral contraceptives.
