The book begins with the story of the author's wife, Marilyn.
Before she met her husband, she was physically and mentally devastated from various surgeries and medications.
She met the doctor, found a new life through natural healing methods, married him, and became healthy enough to give birth to a baby after only 1 hour and 20 minutes of natural childbirth.

What gave her a new lease on life? What completely transformed the body and mind of Dr. Harvey Diamond, a former general practitioner of the obese? Few realize that the human body, while incredibly complex, operates in a remarkably simple manner, governed by the laws of nature.
A person who has reached a certain level does not use difficult terms.
This book, which presents extensive knowledge and diverse experiences in easy sentences that even elementary school students can understand, reminds us that health books can be fun and inspiring.

Following 『The Unchangeable Laws of Dieting』 and 『I Decided to Live Disease-Free』, this is Dr. Harvey Diamond's third masterpiece and New York Times bestseller, published by Simon Books.
It's full of surprising stories about diet and disease that completely shatter all the common sense we've known.

I gave birth to my son naturally without resorting to the help of a hospital.
The labor lasted only 1 hour and 20 minutes.
After a short labor, our son was born at home.
As I was practicing the program, the energy I experienced during my pregnancy was unbelievable.

My father had to try all three of the 'proven scientific treatments' during that time.
Surgery to remove my stomach and a large portion of my intestines was the first, radiation therapy, which caused blisters on my skin, was the second, and chemotherapy, a vigorous regimen of drugs to dull the excruciating pain, was the third.
So, my father's body became a test subject for the medieval warfare using swords, and for the radioactive and chemical warfare of World War II.

Truthful people are committed to what they believe to be true, and they do not shy away from discussing it with truthful people.
They want to be thoroughly examined or tested in what they do.
Even if you lose an argument, instead of blaming the other person, you will thank them for showing you their weaknesses and flaws in their beliefs.

If you could eliminate the toxic waste that accumulates in your body every day, your body would be cleansed.
It means that you can live a comfortable life without disease with a slim body.
I have always emphasized this elimination cycle in my books because detoxification is key to health.

Did you know that 4,000 people die every day in the United States from cancer and heart disease? Over 3,000 people died as a result of 9/11.
So, it's correct to think that 9/11 happens every day in the United States alone.
Their bodies are so full of waste products that have accumulated over decades that their organs simply stop functioning.

Instead of mindlessly consuming the "balanced diet" that experts advocate, you too can see remarkable results by combining foods the way your Homo sapiens digestive system wants.
This is because it is not some magical technique or method, but a principle.
Chimpanzees, whose genes are 99.6% similar to humans, do not mix bread, pasta, meat, and hamburgers.
In the morning, we eat from a banana tree, and in the afternoon, we eat from an orange tree.

Many anatomists unanimously testify that the intestinal structures of humans and chimpanzees, both primates, are remarkably similar.
Every bee on Earth has a digestive system that is exactly the same.
The digestive systems of all giraffes, horses, kangaroos, wombats, gorillas, or even humans, as long as they are of the same species, work in the same way.
You won't find any university physiology textbook that suggests humans naturally have different digestive functions.

The fact is that the eating habit that emphasizes breakfast is one of the most 'detrimental eating habits' on the planet.
You've probably been told since you were a child that you absolutely must eat breakfast for your health.
I did the same.
But the claim that breakfast is the most important meal of the day is pure commercial propaganda.

Humans are designed and evolved to live in nature.
This is because 7 million years ago, apes, the distant ancestors of humans, began living in the forests of Africa.
It has been 40,000 to 50,000 years since the first steps were taken from the African continent to the European continent.
If that's the case, then we humans have lived in the forest for a whopping 6.95 million years.
Our body's genes remember it clearly.

It is already a well-known fact that various diseases are prevalent in farms that drink water that flows from mines such as quarries or gold mines.
All of these waters are full of inorganic minerals.
How did this happen?

The more toxins in your body, the harder it is to sleep at night.
Eating habits based on healthy foods require less energy for digestion.
Healthy foods reduce sleep needs and increase sleep efficiency.
This is why your diet and eating habits have a huge impact on your deep sleep.
The most crucial factor in helping you sleep well is a healthy body.
And that healthy body completes a good night's sleep.

Margarine is a compound that does not melt when squeezed or rubbed with your fingers.
What can be done with these plastic particles in human blood vessels? Margarine is nothing more than a mixture of celluloid fragments.
Every time you eat food containing hydrogenated fat, these debris builds up in your blood vessels.

If we eat pure, natural food whenever we are hungry, we will never lack any nutrients unless we spread our wings and struggle to fly in the sky.
Anything else is just industry hype and is clearly untrue.
Nutrients come from fields, rice paddies, and orchards, not pharmaceutical labs or dead animals!
--- p.238

The reason why my body and mind feel at ease every time I enter the forest is because it is our home.
Could you feel as comfortable as a fish does every time you dive into the ocean? Could you feel as comfortable as a mole does every time you dive into a hole?

The problem of essence should not be solved by technology.
God (nature) is not an object to be analyzed so technically by us foolish humans.
The market is overflowing with diet secrets and miracle cures.
Many experts talk about a 'special secret'.
But such a technical approach can never get to the essence.
