Good Energy
13 minThe New Science of Feeling Great
Introduction
Narrator: A 71-year-old woman, considered "healthy" for her age by a team of specialists, dies just thirteen days after a shocking diagnosis of stage 4 pancreatic cancer. For decades, she had followed her doctors' orders, taking medications for high blood pressure, high cholesterol, and prediabetes. Each condition was treated in isolation, a separate problem managed by a separate pill. Yet, this collection of managed symptoms was merely masking a deeper, systemic breakdown. This woman was Dr. Casey Means's mother, and her tragic, preventable death became the catalyst for a radical re-examination of our entire approach to health.
In the book Good Energy: The New Science of Feeling Great, Dr. Means argues that her mother's story is not an anomaly but the predictable outcome of a broken system. The book posits that the vast majority of chronic diseases—from diabetes and heart disease to depression and infertility—are not separate, complex issues. Instead, they are all symptoms of a single, fundamental root cause: metabolic dysfunction, or what she terms "Bad Energy," at the cellular level.
The Siloed System: Why Modern Medicine Fails at Chronic Disease
Key Insight 1
Narrator: Modern medicine is defined by separation. A patient with multiple complaints is sent to a series of specialists—a cardiologist for the heart, a gastroenterologist for the gut, a psychiatrist for the mind. Each expert focuses on their specific domain, often prescribing medications to manage the symptoms within that silo. The book argues this fragmented approach is a primary reason for the chronic disease epidemic. It fails to see the body as an interconnected system and rarely asks the most important question: why are these symptoms occurring in the first place?
Dr. Means illustrates this with the story of Sophia, a patient she treated during her surgical residency for recurrent sinus infections. Sophia had been suffering for a year, trying various sprays and medications without success. As an ENT surgeon, Dr. Means performed a successful operation, clearing the inflamed tissue. Sophia was grateful. Yet, Dr. Means felt defeated. The surgery addressed the immediate symptom, but it did nothing for Sophia’s other conditions: prediabetes, high blood pressure, back pain, and depression. Dr. Means realized that the inflammation in Sophia’s sinuses was likely connected to a body-wide state of inflammation, and that simply cutting it out was like mopping the floor while the sink overflowed. Sophia wasn't getting better; she was just having her symptoms managed, one by one, and would likely return with another problem in a different silo.
The Unifying Theory of 'Bad Energy': How Cellular Dysfunction Connects Our Ailments
Key Insight 2
Narrator: The book's central thesis is that most chronic symptoms are connected by a shared root cause: cellular malfunction that results in "Bad Energy." When our cells, particularly the mitochondria, cannot efficiently produce energy from food, a cascade of problems begins. This metabolic dysfunction is the common thread linking dozens of conditions that modern medicine treats as unrelated.
This concept is powerfully demonstrated through the story of Lucy, a 36-year-old woman struggling with a host of issues: adult acne, bloating, anxiety, insomnia, and infertility due to PCOS. She had consulted multiple specialists who treated each problem in isolation, and she was on the verge of starting expensive IVF treatments. However, by working with Dr. Means, Lucy began to address the root causes of her "Bad Energy." She changed her diet to eliminate processed foods, optimized her sleep, managed stress, and reduced her exposure to environmental toxins.
Within six months, the results were transformative. Her menstrual cycles normalized, her mood lifted, her digestive issues vanished, and her skin cleared. She was able to reduce her medications and felt more energized than she had in years. Lucy’s story shows that her various ailments were not a collection of bad luck, but rather different expressions of the same underlying metabolic dysfunction. By creating "Good Energy" at the cellular level, she healed the entire system, not just one symptom.
The Profit Motive: Why You Must Trust Yourself, Not the System
Key Insight 3
Narrator: Good Energy delivers a stark critique of the healthcare industry, arguing that it is not designed to create health, but to manage sickness. The system—from hospitals and pharmaceutical companies to insurance providers—benefits financially when people are sick. This creates a powerful incentive to favor interventions, procedures, and prescriptions over preventative, lifestyle-based solutions.
The author shares a chilling anecdote from a friend, a cancer surgeon, who once said, "If you walk through the doors of this surgical oncology department, you are going to get an operation, whether you need it or not." This highlights a culture where intervention is the default, even when palliative care might be more humane and appropriate.
This systemic bias is brought into sharp focus with the story of Dr. Means's own mother's final days. After the terminal cancer diagnosis, the medical team aggressively pushed for invasive procedures—biopsies and stents—that offered a slim chance of extending her life by a few months but came with a high risk of her dying alone in a hospital during COVID-19 lockdowns. The family had to actively fight the system's momentum to honor their mother's wish for a peaceful, comfortable end-of-life at home. They chose to trust themselves over the doctors, and in doing so, they were gifted thirteen final, meaningful days with her. The book argues this is a microcosm of a larger problem: the system's priorities are often not aligned with the patient's.
Bio-Observability: Using Your Own Data to Reclaim Your Health
Key Insight 4
Narrator: If the system cannot be fully trusted, the book argues that individuals must become the CEOs of their own health. The key to this empowerment is "bio-observability"—using modern tools to listen to your body's signals. This means moving beyond a once-a-year physical and taking control of your own health data through standard blood tests and wearable sensors.
The story of Emily, a pregnant woman, exemplifies this principle. Her standard glucose tolerance test came back "normal," and her doctor assured her she did not have gestational diabetes. However, Emily was wearing a continuous glucose monitor (CGM) at the time. Her own real-time data told a completely different story, showing dangerously high glucose spikes that were clearly in the diabetic range. The standard, one-off test had failed her, but her personal data empowered her to make immediate dietary changes to protect herself and her baby.
Good Energy encourages readers to understand key metabolic markers like fasting glucose, triglycerides, HDL cholesterol, and blood pressure, and to aim for optimal, not just "normal," ranges. By tracking this data, individuals can see the direct impact of their food, sleep, and exercise choices, allowing them to make informed decisions independent of a flawed medical system.
The Principles of Good Energy: Aligning Food, Movement, and Rhythm with Cellular Needs
Key Insight 5
Narrator: Creating "Good Energy" is not about following a complex, restrictive diet. It's about returning to the fundamental principles that support cellular health. The book outlines several core strategies, all designed to stabilize blood sugar and reduce inflammation.
First is the principle of eating whole, unprocessed foods. A landmark study by Dr. Kevin Hall at the NIH demonstrated this powerfully. When participants were given unlimited access to ultra-processed foods, they naturally overate by 500 calories per day and gained weight. When given unlimited access to unprocessed foods, they spontaneously ate less and lost weight. This shows that unprocessed food sends the right signals of satiety to the body.
Second is aligning with our natural circadian rhythms. This means getting sunlight in the morning, avoiding artificial light at night, and prioritizing seven to eight hours of quality sleep. Sleep is presented not as a luxury but as a non-negotiable biological necessity for clearing out cellular waste and repairing mitochondria.
Finally, the book emphasizes the importance of constant, low-level movement. It reframes exercise not as isolated gym sessions but as a way of life, arguing that "sitting itself is the monster." Frequent walking and simple resistance training are presented as powerful medicine for improving insulin sensitivity and building metabolically healthy muscle.
Conclusion
Narrator: The single most important takeaway from Good Energy is that the chronic disease epidemic is not an unsolvable mystery. It is the direct result of a fundamental mismatch between our ancient biology and our modern world. The food we eat, the light we are exposed to, our sedentary lifestyles, and the constant stress we endure are sending our cells signals of "Bad Energy," leading to a predictable cascade of disease.
The book's ultimate message is one of radical empowerment. It challenges you to stop outsourcing your health to a system that profits from your illness and to start listening to your own body. The path to good health doesn't lie in the next miracle drug or surgical procedure, but in the daily choices you make. The most challenging idea is also the most liberating: you have more control over your health than you have ever been led to believe. The real question is, are you ready to take it?
