[Illustrated Summary] Rather than 'Living Long,' 'Living Long and Healthy'—4 Strategies Taught by a Doctor
I have translated and summarized books with evidence from overseas into illustrations so you can understand them without reading the originals.
I have kept only the parts that I personally read, tested, and felt were 'the real deal.' This is based on practical experience in the field, not just desk-bound knowledge.
I have broken down difficult technical terms as much as possible and summarized them so that even busy people can read them quickly.
💡 Who should read this:
・There is too much information online, and I don't know what is real. ・I want to choose what is truly good for the health and beauty of myself and my family.
PART 1: Changing Your Mindset
① The core of this book: Rather than 'living long,' 'living long and healthy'
The average life expectancy for Japanese people is 84. However, the healthy life expectancy is about 73.
That is a gap of about 10 years.
The final 10 years are a time when you cannot live without someone else's help.
The author of this book says:
What is important is not 'how long you live,' but 'how long you can stay healthy.'
There is a way to close this 10-year gap.
② It is too late once you get sick
Modern medicine is about 'curing you once you get sick.' If you break a bone, fix it. For infectious diseases, use antibiotics. This is what it is good at.
But what about chronic diseases?
Heart disease, cancer, dementia, diabetes...
These are extremely difficult to 'cure.'
That is why the author advocates for 'Medicine 3.0.'
Medicine that acts before you get sick.
It is an era where you protect your body through 'lifestyle,' not medicine.
③ The secret of centenarians: What people over 100 have in common
Do you think people over 100 are doing some special health regimen?
Actually, there was no 'magic supplement' that most centenarians had in common.
What they have in common is that 'the timing of when they get sick is late.'
This is the key to longevity.
You will get the same diseases.
But 10 to 20 years later.
It is said that what creates that difference is 'daily habits' rather than genetics.
PART 2: Knowing the 4 Great Enemies
4. Metabolic Collapse: The Beginning of Diabetes and Obesity
There are 5.52 million diabetes patients in Japan.
Including those at risk, it is about 20 million.
But the author of this book calls diabetes the 'tip of the iceberg'.
Beneath it lies 'metabolic collapse'.
Fatty liver → insulin resistance → high blood pressure → arteriosclerosis → heart disease → dementia.
It is all connected.
The entrance is 'overeating'.
The exit is 'chronic disease'.
5. Insulin Resistance: The First Sign That the Body Is Breaking Down
Are you relieved because you were told at your health checkup that your 'blood sugar level is normal'?
In fact, insulin resistance begins 'many years' before blood sugar levels rise.
Fat accumulated in the muscles is blocking the insulin keyholes.
By the time blood sugar levels rise, it has already progressed significantly.
Be aware of the danger hidden behind 'normal'.
6. Heart Disease: Arteriosclerosis Starts in Your Teens
Heart disease is the second leading cause of death in Japan.
226,000 people per year.
But it doesn't happen 'suddenly one day'.
Arteriosclerosis starts in your teens.
When the blood vessels of young soldiers who died in war were examined,
there was already plaque (lumps of fat).
In other words, people who have a heart attack in their 50s
had been heading toward it for over 30 years.
If you want to prevent it, do it now.
It will be too late in 10 years.
7. Cancer: A Strategy of 'Preventing Onset' Rather Than Early Detection
Cancer is the leading cause of death in Japan.
384,000 people per year.
But the author of this book says,
'We should change how we fight cancer'.
Current medicine is 'find it and then cure it'.
But by the time cancer is found, it has already been in the body for many years.
Regulate your metabolism, exercise, and reduce inflammation.
Creating a body where cancer cells 'struggle to grow.'
That is the real approach to cancer prevention.
8. Dementia: It begins 20 years before onset
There are about 6 million elderly people with dementia in Japan.
But the scariest part is that 'by the time you notice, it's already too late.'
The abnormal proteins considered to be the cause of Alzheimer's
start accumulating in the brain 20 years before the onset of symptoms.
In other words, for someone who develops it at 70, it had already begun at 50.
If you want to prevent it, do it now in your 40s and 50s.
I really want you to know this.
9. Autophagy: The switch that slows down aging
There is a 'cleaning mode' inside your body.
A mechanism that breaks down and recycles damaged proteins and old cellular waste.
This is autophagy.
But if you are overeating, this switch won't turn on.
Just by creating a little time for hunger, the cellular cleaning begins.
It doesn't have to be fasting.
Leaving 12 hours between dinner and breakfast is enough.
PART 3: Exercise
10. Exercise is the ultimate longevity drug
If 'exercise' were a drug, it would definitely have won a Nobel Prize.
It lowers the risk of everything: heart disease, cancer, dementia, diabetes, and depression.
Moreover, just by moving from the 'lowest level' of physical fitness
to the 'average level,' your risk of death drops by about 50%.
No drug has this effect.
It is a power that only exercise possesses.
11. The Centenarian Olympics: What do you want to be able to do at 80?
What do you want to be able to do at 80?
Be able to pick up your grandchildren?
Climb stairs to the third floor?
Go on a trip by yourself?
Not break a bone if you fall?
The author of this book calls this the 'Centenarian Olympics'.
Set the goal first, then work backward from there to decide on your current training.
Let's take action today for the sake of our 80-year-old selves.
⑫ Aerobic Exercise: Maximum Oxygen Intake Determines Lifespan
Have you ever heard of 'VO2 max'?
This is the body's ability to use oxygen.
People with a low value have five times the mortality risk compared to those with a high value.
Moreover, VO2 max drops by 1% every year as you age.
But you can increase it through exercise.
20 minutes of exercise that gets you out of breath, 3 to 4 times a week.
Just this can turn back your body's 'aging clock'.
⑬ Strength Training: The Reality of a 40% Loss in Muscle Mass by Age 80
By the time you reach 80, your muscle mass will have decreased by about 40% compared to your 20s.
But what's scarier than this is that 'muscle strength' drops 2 to 3 times faster than muscle mass.
'Power' (explosive strength) drops 2 to 3 times faster than that.
In other words, the ability to instinctively put your hands out when you fall is the first thing to disappear.
There is research showing that even if you start strength training in your 60s, half of people don't gain muscle.
If you're going to start, do it now.
PART 4: Nutrition
⑭ The 3 Levers of Nutrition: What, How Much, and When to Eat
There are only three levers for nutrition.
① What to eat (dietary content)
② How much to eat (calorie amount)
③ When to eat (timing of meals)
Any diet method is just adjusting one of these three.
Carbohydrate restriction is ①.
Calorie restriction is ②.
Fasting is ③.
You don't need to overthink it.
Just find the lever that works for you.
⑮ Protein: Most people are not getting enough
Are you getting enough protein?
The author of this book asserts that 'most people are not getting enough.'
Especially after your 40s, muscle mass decreases every year.
To prevent this, you need 1.6 to 2.2g of protein per kg of body weight.
If you weigh 60kg, that's 96 to 132g per day.
That's about 400 to 550g of chicken breast.
It's an amount you definitely won't reach unless you are conscious of it.
⑯ The Trap of Processed Foods: Designed to make you overeat
The reason you 'end up overeating' processed foods isn't because you have a weak will.
Processed foods are 'designed' to make you overeat.
With an exquisite blend of sugar, salt, and fat, you can't stop at 'just one more bite.'
The author of this book says,
'Just avoiding processed foods will solve 80% of your nutritional problems.'
First, try staying away from the convenience store shelves.
⑰ How to find the way of eating that suits you
'In the end, what should I eat?'
The author of this book clearly states,
'There is no perfect diet that works for everyone.'
However, there are 'principles that apply to almost everyone.'
① Reduce processed foods
② Increase protein
③ Increase dietary fiber
④ Don't overeat
Just by following these four things, your body will definitely change.
The correct answer is simple.
PART 5: Sleep and Mental Health
⑱ Sleep: The brain's 'cleaning mode'
The brain has a 'cleaning mode'.
During deep sleep, cerebrospinal fluid flows through the brain, washing away the waste products that accumulated during the day.
Among these waste products is amyloid-beta, which is considered a cause of Alzheimer's disease.
In other words, if you don't sleep deeply, brain waste accumulates every night.
Sleep is not just 'rest.' It is time for a 'deep cleaning' of the brain.
19 The science of how sleep deprivation increases dementia risk
Did you know that just one night of sleep deprivation increases amyloid-beta in the brain?
What if this continues every day? What if it continues for 10 years?
There is research showing that the risk of dementia significantly increases for people who sleep less than 6 hours.
Moreover, the 'quality' of sleep is also important. The shorter the time spent in deep sleep, the higher the risk.
If you want to protect your brain, first of all, get a good night's sleep tonight.
20 If life is miserable, living a long life is meaningless
The author of this book has dedicated his life to longevity research.
But he says this:
'Longevity is meaningless if life is miserable,' 'It's meaningless if your wife hates you,' 'It's meaningless if you are controlled by anger.'
He himself struggled with anger issues and was on the verge of divorce.
He learned firsthand that there is no value in longevity that ignores mental health.
21 Emotional inflammation: The mechanism by which anger and loneliness destroy the body
Chronic stress and loneliness cause 'inflammation' in the body.
This is not a metaphor; inflammatory markers actually rise.
There is research suggesting that lonely people have a mortality risk as high as
smoking 15 cigarettes a day.
Anger, loneliness, and unprocessed trauma.
These are not just 'mental issues' but
also 'physical inflammation.' Let's protect both.
Summary
22. Summary of the 4 tactics: Exercise, Nutrition, Sleep, and Mental Health
The conclusion of this book is simple.
Prevent the 4 major enemies (heart disease, cancer, dementia, and metabolic diseases) with 4 tactics.
1. Exercise: The ultimate longevity drug. Aerobics + strength training
2. Nutrition: Reduce processed foods and increase protein
3. Sleep: Deep cleaning for the brain. 7-8 hours
4. Mental: Prevent mental inflammation
It's nothing special.
But almost no one is doing all of it, right?
23. 7 things you can start today
You thought, 'I can't do all of this,' didn't you?
It's okay.
Just start with one.
1. Walk for 15 minutes in the morning
2. Leave 12 hours between dinner and breakfast
3. Add one protein item to every meal
4. Don't bring your smartphone into the bedroom
5. Do 10 squats twice a week
6. Reduce processed foods by one
7. Contact someone important to you
Just one of these. Try starting today ☺️
24. 3 misconceptions you must avoid
I'll share 3 common misconceptions people have after reading this book.
❌ 'Do extreme fasting' → You lose muscle. A loose time restriction is enough.
❌ 'Do only aerobic exercise' → You lose muscle strength. Pair it with strength training.
❌ 'Try to solve it with supplements' → They cannot replace diet and exercise.
Extremes don't last. 'Slow and steady, but sure' is the right answer.
25. 'Why do you want to live long?'—Something I want you to think about at the end
Finally, I want to share the words of the author of this book.
The most important element in the longevity equation is 'why.'
Why do you want to live long? For whom? For what purpose?
Exercise, diet, and sleep are all just 'means' to an end.
To spend even one more day laughing with the people you love.
I believe that is the best reason to protect your health.
I'm interested in natural remedies, but
I don't know what's genuine and what's suspicious.
In times like that, it's okay not to worry alone.
With over 30 years of experience as a hairdresser,
a psychological counselor,
and a practitioner of natural medicine,
I only deliver 'things that I have tried myself and found to be good.'
