The Hunt Protocol – Cleanshave

A Guide to Reclaiming Your Evolutionary Birthright

By Ellis Vaughn, Ph.D.

“We did not evolve to sit in chairs, to stare at screens, to consume perpetually. We evolved to move, to persist, to hunt. The human body contains ancient wisdom that can only be accessed when we return to the conditions under which it was forged.”

INTRODUCTION

If you’re reading this guide, you’ve taken the first step toward reclaiming what modern civilization has stolen from you, your evolutionary birthright as a persistence hunter.

I’ve spent my life pursuing two seemingly disconnected passions, evolutionary biology and ultra-endurance running. For years, I studied these disciplines separately, publishing research on human evolutionary adaptations by day and pushing my body through hundred-mile mountain races by night. It wasn’t until I experienced what I now call “The Becoming” during the Badwater 135 (a brutal ultramarathon through Death Valley) that I realized these passions were actually the same pursuit.

This guide outlines what I’ve discovered about the extraordinary biological and consciousness-altering potential hidden within the human body, potential that can only be unlocked by recreating the specific conditions under which our species evolved to thrive.

What follows is not a training program for weekend warriors. It is a protocol for those brave enough to strip away modern comforts and reclaim their place in the ancient lineage of human hunters.

MY JOURNEY

Before detailing the protocol, I should explain how I arrived here.

I completed my doctoral research at Stanford University in evolutionary biology, focusing on the physiological adaptations that differentiate humans from other primates. My dissertation, “Endurance Running and Human Evolution: Biological Adaptations for Long-Distance Locomotion,” examined the unique features that make humans exceptional distance runners, our efficient cooling system, tendon elasticity, balanced center of mass, and specialized foot architecture.

The research was well-received academically, but something was missing. I was studying the evolutionary purpose of these adaptations without experiencing them as our ancestors did.

Everything changed when I began running ultramarathons. During a 48-hour race through the Mojave Desert, dehydrated and sleep-deprived, I experienced a profound altered state of consciousness. My perception shifted dramatically, I could sense animal movements at great distances, read subtle changes in terrain, and feel connected to something ancient within my biology.

This wasn’t just runner’s high. This was a fundamentally different state of being that matched accounts from indigenous persistence hunters I had interviewed during my field research. I called it “The Becoming,” the moment when the modern human falls away, and the ancestral hunter emerges.

I left academia to study this phenomenon full-time, self-funding my research through race winnings and minimalist living. After seven years of experimentation, measurement, and refinement, I developed The Hunt Protocol.

THE SCIENCE OF PERSISTENCE HUNTING

To understand the protocol, you must first understand the evolutionary context that shaped your biology.

Approximately two million years ago, our ancestors developed a hunting technique unlike any other predator. Persistence hunting. Unlike ambush predators like lions or wolves, early humans couldn’t outmuscle or outspeed their prey. Instead, they evolved extraordinary endurance capabilities.

The technique works through hunters tracking an animal and pursuing it relentlessly during the heat of the day. While most animals can outpace humans in short bursts, they must stop to cool down through panting. Humans, with our unique ability to sweat and efficiently cool our bodies, can continue pursuing at a steady pace. Eventually, the animal overheats, becomes exhausted, and can no longer flee.

This hunting strategy triggered a cascade of evolutionary adaptations:

Thermoregulation: Humans have 2-5 million sweat glands and can lose up to 12 liters of sweat per day, making us the most efficient coolers in the mammalian world
Bipedalism: Our upright posture reduces sun exposure and improves breathing efficiency during prolonged running
Reduced Body Hair: Facilitates evaporative cooling through sweating
Spring-Like Tendons: The Achilles tendon and arch of the foot store and release energy with each stride
Stabilized Head: The nuchal ligament reduces head movement during running
Enlarged Gluteus Maximus: Stabilizes the trunk during endurance locomotion
Shortened Toes: Improves running efficiency over long distances

These adaptations didn’t evolve for recreational jogging. They evolved specifically for persistence hunting, a process requiring 15-30 miles of running per hunt, often in temperatures exceeding 100°F, while maintaining cognitive functions for tracking.

The most fascinating aspect? This specific combination of conditions triggers unique neurobiological states that modern humans rarely, if ever, experience.

THE BIOCHEMISTRY OF THE HUNT

The Hunt Protocol is designed to trigger a specific cascade of biochemical reactions that our ancestors regularly experienced:

Fasting-Induced Metabolic Shift: After 16-24 hours of fasting, the body depletes glycogen stores and shifts to ketosis. This increases production of beta-hydroxybutyrate (BHB), a ketone body that not only serves as fuel but triggers expression of brain-derived neurotrophic factor (BDNF), which enhances neural plasticity.
Endurance-Induced Hormone Release: Prolonged running (beyond 90 minutes) triggers significant increases in human growth hormone (HGH). Studies show HGH levels can increase by 500-600% during extended exercise, promoting tissue repair, fat metabolism, and muscle growth.
Endocannabinoid Surge: After approximately two hours of moderate-intensity running, the body produces anandamide and 2-arachidonoylglycerol (2-AG), endocannabinoids that create the sensation known as “runner’s high.” These compounds reduce pain perception and anxiety while enhancing sensory processing.
Heat Stress Adaptation: Running in temperatures above 85°F activates heat shock proteins (HSPs) that protect cellular integrity and have been linked to longevity in multiple studies.
Stress-Recovery Oscillation: Alternating between high and low-intensity running mimics the hunting pattern of our ancestors and creates a unique hormetic stress response that strengthens the body’s adaptive capabilities.

When combined in the specific sequence outlined in the protocol, these biochemical processes create what I’ve termed the “Hunter State,” a unique physiological condition that modern humans almost never experience outside of this protocol.

THE HUNT PROTOCOL – CORE PRACTICE

The protocol consists of five phases designed to replicate the conditions of an ancestral persistence hunt:

PHASE 1: THE FASTING (Preparation)

Begin a water-only fast 24-48 hours before The Hunt
Maintain normal activity levels during the first 24 hours
During the final 6 hours, reduce activity to conserve energy
Consume only water with minimal electrolytes (sodium/potassium)
Sleep 8-9 hours the night before The Hunt
Purpose: Triggers metabolic shift to fat utilization, heightens sensory perception, and prepares the neurological system for altered states

PHASE 2: THE TRACKING (Initiation)

Begin at dawn with 5-8 miles of slow, steady running (40-50% max effort)
Focus on heightened awareness of your environment
Practice the tracking meditation: observe animal signs, terrain changes, and weather patterns
Consume no more than 4-6 oz of water per hour
Duration: 60-90 minutes
Purpose: Establishes rhythm, initiates the brain’s transition from analytical to intuitive processing

PHASE 3: THE CHASE (Intensification)

Increase pace to moderate effort (50-70% max)
Incorporate intermittent pushes (30-60 seconds at 80-90% effort)
Cover 8-12 additional miles across varied terrain
Continue minimal hydration protocol
Duration: 90-120 minutes
Purpose: Triggers endocannabinoid release, elevates core temperature to optimal range for neurological shifts

PHASE 4: THE THRESHOLD (Transformation)

Maintain steady effort while incorporating specific breath patterns (detailed in appendix)
Focus on the hunting visualization (seeing through the eyes of the ancestral hunter)
Push beyond conventional fatigue barriers
Cover 5-8 final miles
Duration: 60-90 minutes
Purpose: Facilitates “The Becoming,” the state where modern consciousness recedes and ancestral awareness emerges

PHASE 5: THE BECOMING (Integration)

Slow to walking pace
Perform the integration practices (detailed in appendix)
Record observations and sensory experiences
Duration: 30-60 minutes
Purpose: Integrates the experience and solidifies neurological pathways created during The Hunt

TOTAL PROTOCOL DURATION: 5-6 hours covering 18-28 miles of terrain

PHYSIOLOGICAL MARKERS OF SUCCESS

Those who successfully complete the protocol experience measurable biological changes:

Human Growth Hormone increases of 400-700% from baseline
Cortisol reduction of 30-50% following completion
Significant elevation in anandamide and 2-AG (endocannabinoids)
Dramatically increased fat oxidation rates
Extended BDNF elevation for 24-72 hours post-Hunt
Measurable changes in default mode network activity in the brain
Reduced inflammatory markers for 3-5 days following The Hunt

More remarkable are the consciousness changes reported by those who reach The Becoming:

Dissolution of the boundary between self and environment
Heightened sensory perception, particularly smell and hearing
Intuitive understanding of animal movement patterns
Time dilation (perception of slowed time)
Access to what participants describe as “blood memory,” intuitive knowledge they cannot explain
Profound sense of connection to ancestral lineage

PROGRESSION AND COMMUNITY

The Hunt Protocol is not designed to be practiced alone. Our ancestors hunted in groups, and The Hunters maintain this tradition. After completing your first three solo Hunts, you’ll be invited to join group Hunts where experienced practitioners guide newer members through increasingly challenging terrain and distances.

Advancement through the community is based not on speed or distance but on the depth of your connection to The Becoming. Senior Hunters can recognize the subtle signs of true integration and will guide your progression accordingly.

BLOOD METRICS TRACKING

A unique aspect of our approach is the optional monitoring of blood biomarkers before, during, and after The Hunt. By measuring hormonal changes, metabolic markers, and unique compounds produced during The Becoming, we’re creating the first scientific documentation of this ancestral state.

For those who choose to participate in this research, we provide detailed testing protocols and equipment for measuring:

Growth hormone fluctuations
Endocannabinoid levels
Ketone body production
Neurotransmitter metabolites
Novel compounds we’re still working to identify

This data helps refine individual protocols and contributes to our growing understanding of human evolutionary potential.

WARNINGS AND CONTRAINDICATIONS

The Hunt Protocol is not for everyone. Do not attempt this protocol if you:

Have not completed at least three ultramarathons of 50+ miles
Have any cardiovascular conditions or abnormalities
Have eating disorders or metabolic conditions
Are pregnant or nursing
Are under 21 years of age
Have not consulted with a physician familiar with extreme endurance pursuits

Even with proper preparation, participants should be aware that The Hunt Protocol deliberately pushes the human body into extreme states. This is not a fitness program, it is a conscious choice to experience the conditions under which our species evolved.

CONCLUSION

Modern humans are trapped in bodies designed for conditions we no longer experience. We suffer not because life is inherently difficult, but because we have lost connection with the specific environmental triggers that activate our highest functioning.

The Hunt Protocol is not about fitness or performance. It is about reclaiming your place in the ancient lineage of human hunters, those who sustained our species through two million years of evolution.

The path is difficult, but those who persist discover that beneath the veneer of civilization lies an organism of extraordinary capability, waiting to be reawakened.

The Hunt awaits.
