🧐If you consider your body as a system, then all your discomforts might be caused by "long-term systemic deficits" at the bodily level!

The core principle I adhere to in investing is: principal + being alive, because as long as you're in the market, there’s always a chance; with the principal in hand, you can always make a comeback.

And we all know a harsh fact: through multiple bull and bear markets, I’ve realized that what’s truly deadly is never a single margin call, but the long-term accumulation of small mistakes leading to behavioral deformation.

The same applies to the body: all chronic diseases, fatigue, emotional outbursts, decline in energy—at their core, they are results of “cells not receiving stable energy”; consequences of long-term instability and poor health.

Recently, I watched a long discussion between Yin Ye and Tuo Buhua about how we need to treat our bodies as a “system.” The key to health is enabling the body to continuously and stably produce and distribute “good energy.”

If you care about “long-term stability” rather than short-term states, the following book is worth reading repeatedly. Highly recommended:

**"Good Energy: The Surprising Connection Between Metabolism and Limitless Health"**

Author: Casey Means, a functional medicine doctor and entrepreneur in the US, founder of the digital health company Levels Health.

I believe the core argument is especially relevant for all modern people, particularly friends in the Web3 community:

Casey Means has done something very important:
She has shifted health from the “disease—medication model” back to the “energy—system model.”

First layer summary: The three misconceptions she aims to correct

1️⃣ The blind spot of modern medicine isn’t that it can’t cure diseases, but that it’s “too late”

Acute illnesses: Modern medicine excels (infections, trauma, surgery)

Chronic illnesses: Almost completely ineffective (diabetes, cardiovascular diseases, Alzheimer’s)

The problem isn’t that medicine isn’t advanced enough; it’s that chronic diseases don’t “happen suddenly,” but are the final manifestation of long-term metabolic imbalance.

Fatigue, insomnia, emotional issues, acne, obesity, insulin fluctuations—these are not “small problems,” but early signals that the system is beginning to break down.

2️⃣ You’re “eating too much,” but your cells are “starving”

This is one of the most counterintuitive and important points in the book:
Excess fat → Insulin resistance

Insulin failure → Glucose can’t enter cells

Result: Nutrient overload + cellular energy deficiency

The author calls this: Bad Energy

And the essence of health is: delivering energy to the right cells, in the right way, at the right time.

3️⃣ Bodily discomfort = System alert, not “just endure it”

There’s a very heavy but crucial statement in the book:

All discomforts in the body are “abnormal.”

Fatigue is not normal
Emotional outbursts are not personality traits
Weight gain is not inevitable in middle age
Insomnia is not just bad luck

These are signals from the system, but we habitually ignore them.

Second layer summary: She proposes a set of “metabolism as operating system” ideas

1️⃣ Health ≠ just good indicators, but “biological observability”

She introduces a very “engineer’s mindset” concept:

Biological Observability

Like flying an airplane:
You don’t rely on “feelings” to fly
But on real-time instrument calibration

Key indicators include:
Fasting blood glucose
Triglycerides / HDL
Waist circumference
Blood pressure
Fasting insulin (extremely critical)

Continuous Glucose Monitoring (CGM) isn’t for “control,” but for “understanding yourself.”

2️⃣ Food isn’t just calories, but “information input”

This is the highest level of nutritional understanding in the book:

What you eat isn’t just energy; it’s coding for your body.

Food will:
Alter hormones
Affect neurotransmitters
Impact mitochondria
Change gene expression
Reshape gut microbiota

So the question isn’t “what to eat,” but:
What signals are you sending to your body every day?

Therefore, she offers two simple but powerful principles:
Be comprehensive, not excessive
Be steady, not fluctuating (especially blood sugar)

3️⃣ All lifestyles are fundamentally about “optimizing the energy curve”

Whether it’s:
Exercise (especially NEAT + aerobic + resistance)
Sleep (circadian rhythm)
Sunlight
Cold and heat exposure
Stress management
Social connection

The essence isn’t “health tips,” but improving energy production efficiency and stability.

Ultimate elevation: what this book truly aims to convey isn’t just health

If you abstract this book one layer, it’s actually about a very universal underlying logic:

1️⃣ All long-term breakdowns stem from “systemic chronic imbalance”

Whether it’s:
Body
Mind
Career
Wealth
Relationships

The real killer isn’t a single failure, but long-term small deviations that go uncorrected.

2️⃣ Advanced ability isn’t controlling results, but enhancing “observability”

Visible → then you can adjust: That’s why I always recommend using the best visualization tools like OURA or Whoop.

Perception dullness → inevitably missing windows: Correct now, but it may not be immediately effective; persistence is needed.

The body and life are the same.

3️⃣ True “limitless health” isn’t about extremes, but stability

This book’s worldview is very mature:

It’s not about pursuing peak states, but about “long-term non-collapse”:

Just like investing, it’s not about chasing sudden huge profits but about staying in the market long-term without crashing.

Stable energy
Stable rhythm
Stable input
Stable recovery

This is the sustainable state of life.

To conclude with a more “elevated” phrase:

Investing isn’t about getting rich overnight, but about building your own investment system, maintaining a good mindset and cash flow, and staying at the table long-term.

Similarly, health isn’t about fighting disease but about continuously keeping the system in a state of “reachable energy, clear signals, timely feedback.”

Personally, I believe that if you agree that “fewer mistakes, longer life” is a high-level skill, then this book, *Good Energy: The Surprising Connection Between Metabolism and Limitless Health*, is worth placing in your long-term cognitive portfolio.
