“Disease and aging problems depend on cellular energy!”
The most innovative solution in an era of chronic illness

Modern medicine is becoming increasingly precise, and we are prescribed far more medications than ever before.
But our health is not improving, and we are relying on too frequent treatments.
The number of people with chronic diseases is increasing, and problems such as fatigue, anxiety, overweight, depression, and poor concentration have become commonplace.
This is the same not only in American society but also in Korean society.
Now, six out of ten adults have a chronic disease, and even children are diagnosed with obesity, fatty liver disease, and attention deficit disorder.
Every day, we take more supplements, visit hospitals, and consume more health content, but why does our body continue to break down?

“Good Energy” begins with this simple, yet uncomfortable question.
“The problem isn’t the disease itself, it’s that our body’s cells aren’t making energy properly,” says Dr. Casey Minns, a surgeon and Stanford University School of Medicine graduate and author of the book.
The author left the hospital to pursue research on cellular metabolism and bioenergy, seeking to fundamentally understand why patients return to the hospital with the same symptoms.
And based on years of clinical and practical experience, I have come to the strong conclusion that “most chronic diseases have one cause: cellular energy disorders.”

As soon as it was published, this book reached number one on Amazon's overall bestseller list and the New York Times bestseller list, captivating millions of readers around the world.
If you are someone who always feels tired, sick, and worn out, you will discover the cause and treatment in this book.

I weighed 5.2 kilograms when I was born.
Doctors congratulated the mother for giving birth to the largest baby in the hospital's history.
The weight gained during pregnancy did not go away easily, and my mother continued to struggle to lose weight for several years afterward.
My mother's doctor said this was normal.
She just told me to eat 'healthier foods' because I had just had a baby and was getting older.
My mother was diagnosed with high blood pressure by a cardiologist in her 40s.
The doctor prescribed an angiotensin-converting enzyme inhibitor, which prevents arteries from constricting, saying that this was very common in women my mother's age.

My mother, now in her 50s, was told by her internist that she had hypercholesterolemia (more precisely, high triglycerides, low HDL cholesterol, and high LDL cholesterol).
My mother was told that being prescribed statins was almost a rite of passage at her age.
Statins are one of the most prescribed drugs in U.S. history, with 221 million prescriptions filled each year.


When I turned 60, I was told by an endocrinologist that I was pre-diabetic.
The doctor emphasized that this is also very common and not something to worry about.
In any case, it is still in the 'pre-diabetic' stage, and 50 percent of American adults are said to be in the pre-diabetic stage.
My mother left the doctor's office with a prescription for a drug prescribed more than 90 million times a year in the United States.

In January 2021, my 71-year-old mother was hiking with her father as they did every day near their home in Northern California.
Suddenly, I felt a severe stomachache and felt more tired than usual.
My mother was worried and went to her doctor, who told her to get a CT scan and other tests.
The next day, my mother received a text message informing her that she had stage 4 pancreatic cancer.
Thirteen days later, my mother passed away.

Despite surgically treating inflamed tissue in the head and neck every day, I never learned about the causes of inflammation in the body or its connection to the chronic inflammatory diseases that so many people face today.


I was never asked to ask, 'Why is there so much inflammation?'
I had a gut feeling that all of Sophia's ailments might be related, but instead of delving into that curiosity, I always wrote prescriptions and held the scalpel within the guidelines of my specialty.
Immediately after meeting Sophia, I felt a strong sense that despite the sheer size and scope of our healthcare system, I couldn't operate on other patients until I understood why my patients and those around me were sick.

I wanted to understand why so many diseases were increasing exponentially and why they showed clear patterns indicating potential connections.
And it was considered of utmost importance to figure out what we could do as doctors to keep patients out of the operating room.
I became a doctor to help patients find basic health and live vibrant lives.
I didn't become a doctor to give medicine to as many patients as possible, perform surgeries, and charge hospital bills every day.

Although I was surrounded by doctors who had entered medicine to help patients, the reality became increasingly clear: every institution that affected health—from medical schools to insurance companies, hospitals, and pharmaceutical companies—made money from the "management" of disease, not from the treatment of patients.
It was clear that these incentives acted as an invisible hand that led good people to tolerate bad outcomes.

After years of research into what causes inflammation in patients like Sarah, the answer was surprisingly simple.
In many cases, chronic inflammation is a response from the body's cells that feel threatened by persistent energy shortages due to poor energy metabolism.
Immune cells rush to the area of ​​the body at risk, causing inflammation.

Energy-deficient cells, that is, cells with impaired metabolic function that makes it difficult to produce energy and perform other functions, sense that they are threatened and in danger.
These unstable cells send out chemical alarm signals, asking the immune system for help.
In the process of trying to help, immune cells cause tremendous collateral damage.
It literally starts a war to protect itself from itself, which leads to more serious symptoms.
This is the core cause of chronic inflammation with metabolic dysfunction and a wide range of symptoms.

Jumping into the world of cell biology can be a daunting undertaking.
But there is one simple measure that can effectively reframe how we understand health and disease.
It measures whether the mitochondria within the cell are producing energy well or poorly.
You may have heard the word 'mitochondria'.
You probably learned about it in high school biology class as the 'power plant of the cell.'


Mitochondria convert calories from food into cellular energy.
These tiny organelles are the converters that convert the breakdown products of the food we eat into energy that the cell can use to do various tasks.
The amount of mitochondria present in each cell type in our body, such as the liver, skin, brain, ovaries, and eyes, varies greatly.
Depending on the type of work the cell needs to do and the amount of energy it needs to do that work, some cells have hundreds of thousands of mitochondria, while others only have a few.
--- From "ATP, the energy currency we pay for life"

It is not a metaphor to say that we are made of sunlight.
Almost all the energy we consume through food comes directly from the sun.
For most of us, photosynthesis is a term we learned in middle school and quickly forgot.
But remember this miraculous fact:
The energy that comes from the sun and travels about 150 million kilometers through space is stored in the chemical bonds of glucose molecules produced by plants.
Even if we stick to a meat-based diet, many of the animals we eat are herbivores, so most of the energy we get from our food comes from the sun.
The sun is the source of our life.

Let's also not forget that photosynthesis creates the oxygen that every cell in our bodies needs to produce energy.
Life exists on Earth because of the sun.
It is a shameful blind spot in medicine that we have not learned about the three major pathways that are crucial to bodily function.
Since the emergence of the simplest forms of life, regular patterns of light and dark have been the consistent environmental stimuli driving human physiology.
Human cells are encoded with a 24-hour sleep-wake cycle, switching from an active and feeding mode when exposed to sunlight to a resting and fasting mode when in the dark.
The physiological functions of these two cycles, including gene expression, metabolism, and hormonal activity, are very different.


The amount of light exposure determines which cycle you fall into.
Inconsistent or irregular exposure to light and dark, which sends the body conflicting signals, can lead to dysfunction and disease.
Sunlight entering the eyes is like an activation switch for the body.
The amount of light received outdoors on a clear day is 100 times greater than the amount of light received indoors from artificial lighting.
Even sitting under a shady tree exposes you to more light than sitting indoors with artificial lighting.
