Why Medical School Failed My Clients

By Marc Bates

Medical school taught doctors that they should be knowledgeable about everything related to prescribing medications and performing surgeries. It taught them almost nothing about nutrition.

Four years of intensive medical training. Thousands of hours studying anatomy, physiology, pharmacology, and pathology. The total time spent learning about nutrition? Less than two hours.

They didn't realize this gap was killing their ability to help patients and me until I faced my own health crisis.

The Moment Everything Changed

Despite following what I believed was a balanced diet, I struggled with migraines, excess weight, and suboptimal energy. My doctor, as a medically trained professional, instinctively tried to solve these issues the way he was taught.

Standard diagnostics. Medications, when necessary. The established guidelines for "balanced" eating and exercise.

Nothing worked.

The turning point came during a conversation with a cardiologist who mentioned that nutrition could reverse coronary artery disease. This knowledge was relegated to a poorly attended lunchtime elective because the mainstream curriculum prioritized profitable interventions like surgeries and stents over nutrition education.

That's when he realized the full extent of the problem. Medical schools provide only 19.6 hours of nutrition education across four years of training. Less than 1% of total lecture hours.

They were being trained for "Band-Aid sick care" instead of addressing root causes.

My Accidental Discovery

Frustrated by conventional medicine's failures, I began experimenting with different dietary approaches. I tried everything: vegan, vegetarian, Atkins, paleo, Mediterranean.

Then I discovered the carnivore diet.

The transition from vegetarianism to eating only animal products seemed extreme. But within weeks, something remarkable happened.

My joint pain disappeared. Digestive issues that had plagued me for years vanished. Energy levels soared. Mental clarity improved dramatically.

Most striking was what happened when I reintroduced plant foods. Digestive discomfort returned immediately. Inflammation came back. My body was telling me something my medical training had never prepared me to understand.

Three Pillars of Evidence

As a trained researcher, I needed more than personal experience. I built my understanding on three pillars of evidence that challenged everything I thought I knew about nutrition.

The Anecdotal Pillar

I started documenting reports from carnivore diet adherents. The patterns were consistent and remarkable.

Weight loss without calorie counting. Muscle gain. Increased energy. Better facial symmetry. Elimination of dental cavities. Reversal of conditions like diabetes, depression, and anxiety.

I met many vegetarians and vegans who transitioned to carnivore diets. I never encountered carnivores who switched to veganism.

This one-way migration pattern suggested something profound about human dietary needs.

The Population Studies Pillar

I examined indigenous populations like the Maasai tribe, who primarily consumed meat and dairy. They exhibited superior physical attributes: greater height, muscle density, bone density, perfect dental formation, and absence of degenerative diseases.

When tribe members adopted Western diets with processed foods, their health deteriorated significantly. This suggested diet, not genetics, was the determining factor.

But then I discovered something that shook my faith in population studies entirely.

The famous Blue Zones, celebrated for plant-based longevity, had serious data problems. Government audits revealed that 72% of Greece's claimed centenarians were already dead. Japan found that 82% of their centenarians were missing or deceased.

These weren't isolated incidents. They were systematic problems with pension fraud and misreported ages undermining the entire foundation of longevity research.

The Biochemical Pillar

The most compelling evidence came from biochemistry. Human metabolism operates through two primary pathways: glycolysis (carbohydrate-based) and fat oxidation.

Ketone metabolism produces what I call "cleaner energy" at the cellular level.

When cells metabolize glucose, they generate reactive oxygen species that damage DNA, proteins, and lipids. These free radicals contribute to inflammation and aging.

Ketone metabolism produces significantly fewer of these damaging byproducts. Beta-hydroxybutyrate has a higher hydrogen-to-carbon ratio than pyruvate, yielding more free energy per mole of oxygen with fewer reactive oxygen species.

Ketones enter the tricarboxylic acid cycle more efficiently than glucose-derived pyruvate. They bypass insulin dependence entirely, making them a reliable fuel source even in insulin-resistant states.

This biochemical superiority isn't opinion. It's measurable, objective science.

The Industry Influence Reality

My investigation revealed why this information remains hidden from medical education.

In the 1960s, the Sugar Research Foundation paid Harvard researchers the equivalent of $48,000 in today's dollars to downplay sugar's role in heart disease and shift blame to dietary fat.

These scientists authored reviews published in prestigious journals that shaped decades of dietary guidelines. One of the paid researchers later became head of the USDA and authored influential guidelines that demonized fats while exonerating sugar.

This wasn't conspiracy theory. It was documented historical fact, confirmed by peer-reviewed research analyzing internal industry communications.

Why Medicine Resists Change

The medical establishment's resistance to carnivore diets stems from multiple factors beyond industry influence.

Medical training creates deeply ingrained frameworks emphasizing carbohydrate-centric guidelines and the dangers of saturated fat. Challenging these beliefs requires uncomfortable unlearning and relearning.

Physicians fear professional backlash. Being labeled as fringe or unscientific can impact reputation, career advancement, and patient trust.

Healthcare institutions prioritize standardized protocols that are slow to evolve. The medical system's structure focuses on pharmaceuticals and procedures, creating economic incentives that don't align with dietary interventions.

Dietary changes are less profitable and harder to monetize than drugs and surgeries.

A Practical Transition Roadmap

For those intrigued but overwhelmed by eliminating plants entirely, I developed a gradual transition protocol.

Week 1: Add three fully meat-based meals while maintaining some plant foods. Focus on easily digestible animal products like eggs, fish, and ground meats. Reduce high-fiber vegetables by 25%.

Week 2: Increase to eight carnivore meals. Reduce dietary fiber by 50%, eliminating the most fibrous and oxalate-rich plants first. Increase salt intake to support electrolyte balance.

Week 3: Introduce two full carnivore days. Continue tapering fiber-rich foods by 75%. Monitor energy levels and bowel movements closely.

Week 4: Progress to five full carnivore days. Eliminate most plant foods. Include organ meats and bone broth for nutrient density. Maintain adequate fat intake.

Week 5: Consume 85% carnivore meals. Focus on eating to satiety, avoiding undereating which causes fatigue. Monitor for digestive symptoms.

Week 6: Transition to 100% carnivore. Continue enjoying variety in animal products. Maintain hydration and salt intake.

Warning signs to slow down include severe digestive distress, excessive fatigue, dizziness, nausea, mental fog, or unintended rapid weight loss. If these occur, reintroduce some tolerated plant foods temporarily and consult a healthcare professional familiar with ketogenic approaches.

Navigating Professional Cognitive Dissonance

For medical professionals reading this and feeling tension between training and experience, I offer this guidance.

Acknowledge that feeling dissonance between formal education and clinical observations is valid. Medical education provides limited nutrition knowledge, creating gaps when faced with real-world patient outcomes.

Commit to lifelong learning beyond medical school. Develop skills in critical appraisal of studies, understanding biases and conflicts of interest to discern reliable evidence from industry-influenced data.

Prioritize patient outcomes over rigid adherence to guidelines that may not fit every individual. Use shared decision-making, respecting patient responses to different dietary approaches.

Maintain professional integrity through transparency about the limitations of current medical knowledge and the evolving nature of nutrition science.

Connect with professionals in nutrition and metabolic health to share knowledge and strategies for integrating new evidence into practice.

The Most Important Lesson

If you could speak to your younger self at the beginning of medical school, I bet you would give one crucial piece of advice.

Take ownership of your nutrition education from the very start. Understand that nutrition is the foundational pillar of health and disease prevention, far more powerful than many pharmaceutical interventions taught in medical school.

Recognize the limitations and biases within conventional medical education. Be proactive in seeking integrative, metabolic, and functional medicine knowledge.

Develop curiosity and skepticism toward established dogma. Always question and validate with scientific evidence and clinical outcomes.

This early focus would have saved years of frustration, improved patient care, and empowered a more effective approach to chronic disease management.

Individual Variation Matters

The carnivore diet isn't a universal solution. Individual responses vary based on genetics, health status, and lifestyle factors.

Listen to your body and adjust accordingly. Some people may benefit from including organ meats, seafood, or limited dairy if tolerated.

Transition thoughtfully and gradually to minimize symptoms like digestive upset. Supportive measures including adequate hydration, electrolyte balance, and possibly supplementation can enhance adaptation and safety.

The carnivore diet often faces skepticism due to its restrictive nature and departure from mainstream guidelines. Approach discussions with open-mindedness and respect, recognizing that dietary choices are deeply personal.

Nutrition science continues evolving. More rigorous, long-term studies on carnivore and ketogenic diets are needed. My approach remains grounded in current evidence, clinical experience, and biochemical rationale, but stays open to refinement as new data emerge.

The carnivore diet represents a powerful tool within a personalized, well-supported framework. Embracing flexibility, ongoing learning, and respectful dialogue maximizes its benefits and advances nutritional science.

Medical education failed to prepare me for the most important intervention I could offer patients. Nutrition isn't just medicine. It is medicine.
