The Body’s Secret Language: Understanding the Deficiency Theory
Welcome to a new way of looking at your well-being. My mission is to help you move from confusion to clarity by uncovering the “Why” behind how you feel. In our journey together, we must first learn to listen to the body’s secret language. Most of what we call “sickness” is actually the body’s way of communicating a state of incompleteness. I call this the Deficiency Theory.
1. Deficiency Theory Introduction: From “Disease” to a “Lack of Ease”
In the world of conventional medicine, we often treat the body like a machine with parts that randomly fail. We give a name to a group of symptoms and call it a “disease.” But if we look closer at the roots of health, we find that most issues stem from a deficiency—a state where the body lacks the essential elements it needs to function. When we identify these shortages, the heavy burden of “sickness” begins to lift, and we can guide the body back to its natural rhythm.
Key Definition: Deficiency A state of being incomplete or inadequate; a lack or shortage of something essential to health. It is more than just a missing vitamin; it describes a fault or a failure that makes the system “not good enough” to perform its vital work.
Key Definition: Disease An abnormal condition resulting from infection, inflammation, or genetics. Literally, it is a “lack of ease”—a state where the body is troubled because it is no longer functioning in its natural, healthy flow.
When our body starts sending signals, it isn’t attacking us; it is pleading for the resources it needs to restore that “ease.”

2. Symptoms vs. Deficiencies: The Alarm vs. The Cause
Imagine you are at home and your smoke alarm starts screaming. Conventional medicine often focuses on “treating the symptom,” which is the equivalent of taking the batteries out of the alarm to stop the noise while the kitchen is still on fire.
The Deficiency Theory teaches us to look for the fire. For example, if your heart is palpitating, you might be offered a prescription to suppress the rhythm. But as a health detective, we ask: Is this an alarm for dehydration? Is it a magnesium shortage? By providing what is missing, the alarm naturally turns off because the body is no longer in danger.
The Symptom vs. The Shortage
| Common Symptom | Potential Underlying Deficiency |
| Heart Palpitations | Magnesium deficiency or Dehydration |
| Anemia | Shortage of Iron, B12, B6, or Folic Acid |
| Chronic Fatigue | CoQ10 deficiency (impacting cellular energy/ATP) |
| Persistent Skin Issues | Lack of specific gut bacteria (Bifidobacteria) |
When we shift our focus from suppressing the alarm to replenishment, we give the body the tools to heal itself.

3. The Logic of the Deficiency Theory: Why the Body Gets Sick
To understand why we run low on resources, I like to use a financial metaphor. Think of your health like a bank account. You can end up “broke” for three specific reasons:
- Genetic Variant Expression (The “Software Glitch”): This is your unique “instruction manual.” Sometimes, our DNA has a “snip” (SNP) that acts like a software glitch in the bank’s computer. Even if the money is there, the system can’t process it correctly, making it hard for your body to create the enzymes needed to absorb or use nutrients.
- Lack of Nutrients in the Diet (Not Making Enough): This is the most straightforward cause. If you aren’t “earning” enough nutrients through high-quality food, your body eventually runs out of its “savings” and symptoms emerge.
- Too Much Nutrition or Nutrients (The “Overload”): This sounds counterintuitive, but you can be deficient because you are over-consuming things your body cannot break down. If you have “leaky gut” or are over-supplementing, you create an environment where nutrients are present but can’t get to where they need to go, or they interfere with other vital processes.
Our unique genetic blueprint is the map that helps us find exactly which of these “budget issues” is causing our specific health challenges.

4. The Genetic Puzzle: SNPs and the FUT2 Example
Every one of us is a unique puzzle. In this puzzle, SNPs (Single Nucleotide Polymorphisms) are pieces of instructions that are either “turned off” or altered. A beautiful example of this is the FUT2 gene.
This gene programs an enzyme that produces a specific sugar (an oligosaccharide) on the surface of your cells. This sugar isn’t just a byproduct; it is the essential food for a very important strain of “good” bacteria called Bifidobacteria.
I once worked with a mother and child struggling with persistent, visible skin issues. They had tried everything—gluten-free, dairy-free, and general probiotics—but nothing worked.
The Discovery: Genetic testing showed they were “non-secretors” (homozygous for the FUT2 variant). Their bodies were not programmed to produce the sugar that feeds Bifidobacteria. Because the mother didn’t produce this sugar in her breast milk, her child was born into a state of immediate deficiency.
The Solution: We didn’t need to change their whole lives; we just needed to provide the missing piece. We targeted the specific Bifidobacteria strains they couldn’t feed naturally. The result? The skin cleared immediately, within just one to two weeks. It was a life-changing “aha!” moment that only happened because we looked at the genetics.

5. DIND: The Hidden Cost of Covering Symptoms
Sometimes, the very tools we use to feel better are the things stripping us of our health. This is DIND (Drug-Induced Nutrient Depletion). Common medications can deplete vitamins and minerals, creating “new” symptoms that are often mistaken for entirely new diseases.
I take this personally because I carry a specific genetic SNP that makes certain medications dangerous. For the 5% of the population with this variant, Statin drugs (for cholesterol) can be lethal. Statins deplete CoQ10, a nutrient vital for the “powerhouse” of your cells. If you already have a genetic “glitch” that lowers CoQ10, taking a statin can lead to severe myopathy (muscle death).
The Hidden Cycle of DIND:
- The Initial Symptom: High cholesterol or blood pressure.
- The Medication Intervention: A drug is prescribed to suppress the number.
- The Resulting Nutrient Depletion: The drug strips the body of a key resource (like CoQ10 or Magnesium).
- The Emergence of “New” Problems: You develop extreme fatigue or muscle pain. This is often treated with morepills rather than recognizing the drug-induced deficiency.

6. Conclusion: Becoming a Health Detective
True wellness requires a total mindset change. We have to stop thinking of health as a light switch that is either “on” or “off.” Instead, think of it as a sliding scale. Your body is incredibly resilient; it can compensate for deficiencies for a long time—until it hits a tipping point.
The Tipping Point of Health:
- 60% Function: You are healthy. Your body is managing its deficiencies well enough to keep you moving.
- 59% Function: You are “sick.” This 1% difference is the threshold where the body can no longer compensate.
Think of the man who picks up a simple pencil and his back “goes out.” It wasn’t the pencil that caused the injury; it was the fact that his body had been hovering at that 60% line for years, and that one tiny movement pushed him to 59%.
You are the primary investigator of your own health. By looking at your body through the lens of the Deficiency Theory, you move away from “pill-popping” and toward true replenishment. Ask yourself: what is my body missing, and how can I give it the “ease” it deserves?

Take a moment to listen to what your body is whispering. Ask yourself:
- Is this symptom an alarm or the cause? (Am I just trying to silence the “smoke detector”?)
- What is my “Software Glitch”? (Could a genetic SNP be the reason a “healthy diet” isn’t working for me?)
- Am I in a DIND cycle? (Could my medications be creating a new deficiency that looks like a new illness?)
