Health Optimization Medicine Podcast

In this episode of the Health Optimization Medicine Podcast, Dr. Scott Sherr, Jodi Duval, and Dr. Allen Bookatz explore what happens inside the cell when the body perceives stress or danger.
The discussion focuses on Dr. Robert Naviaux's Cell Danger Response and how mitochondria can alter energy production and signaling in response to perceived threats. The team examines why fatigue, brain fog, inflammation, and exercise intolerance can occur even when standard laboratory testing appears normal, and how the different phases of the cellular response are meant to move from defense through repair and recovery.
Join us as we delve into:
Stress at the Cellular Level: How mitochondria and cells respond when they perceive danger from infection, toxins, injury, environmental exposures, or psychological stress.

Why Normal Labs May Not Explain Fatigue: Why standard testing may not capture changes in cellular signaling, mitochondrial output, or a cell's metabolic state.

The Three Phases of the Cell Danger Response: How CDR1 involves inflammatory defense, CDR2 involves proliferation and rebuilding, and CDR3 involves differentiation and recovery.

Stress, Mitochondria and Energy: Why cells may reduce energy output while continuing to interpret their environment as unsafe.

Hormesis and Stress Dosing: Why exercise, temperature exposure, and other acute stressors may be useful when properly dosed, while excessive stress may add to the existing burden.

Mitochondrial Nutrient Support: The role discussed for CoQ10, PQQ, magnesium, and NAD+ precursors in supporting the metabolic machinery during the transition through the CDR phases.

Parasympathetic Safety Signaling: How extended-exhale breathing, HRV biofeedback, vagal tone work, and other approaches are discussed as ways to reduce chronic sympathetic input.

The Limits of the Framework: Why deliberately adding stress to an already overloaded system may be counterproductive when the dose is not appropriate.

Disease Management vs. Health Optimization: Why the HOMeHOPe approach looks not only at the trigger but also at the conditions the cell may need to complete its response.

In this episode of the Health Optimization Medicine Podcast, Dr. Ted Achacoso, Dr. Jup Kuipers, Boomer Anderson, Dr. Allen Bookatz, and Dr. Scott Sherr explore a difficult question: can we influence the biology of an aging brain carrying APOE4 risk?
APOE4 is not simply a diagnosis, and a genetic result does not tell us what is happening in someone's brain today. The team looks at how APOE4 may affect lipid transport, microglial behavior, vascular integrity, glucose utilization, mitochondrial function, circadian biology, and epigenetic maintenance.
The discussion also lays out a practical three-phase framework: establish the phenotype, reduce ongoing stressors, restore circadian and bioenergetic alignment, and track whether cognitive, functional, metabolic, vascular, and biological age measures actually improve over time.
Join us as we delve into:
APOE4 Risk vs Diagnosis: What one versus two APOE4 copies may mean, and why genotype is not the same as the current clinical stage.

Cellular Energy and Epigenetic Maintenance: Why disrupted energy metabolism can affect the conditions needed for normal transcription and epigenetic maintenance.

Circadian Biology, NAMPT and NAD+: How CLOCK and BMAL1 influence NAMPT and the NAD+ salvage pathway, and why disrupted circadian rhythms can affect cellular maintenance.

Health Optimization Medicine vs Disease-Centered Prevention: Why the HOMe approach focuses on the cellular environment and the conditions that create and sustain health.

The Three-Phase Clinical Framework: How to establish a baseline phenotype, reduce exposomic stressors, restore circadian and bioenergetic alignment, and track outcomes over time.

The Skeptical Position: The team considers the argument that APOE4-driven pathology may be too genetically determined for lifestyle and metabolic tuning to meaningfully change the trajectory.

What Does a "Reset" Actually Mean?: Why a reset is a claim that needs to be demonstrated through durable improvements in cognition, function, and biomarkers over time.

This episode is for you if:
You have undergone genetic testing and want to better understand what an APOE4 result does and does not tell you.

You are interested in the relationship between APOE4, brain aging, metabolism, vascular health, and mitochondrial function.

You want to understand how circadian biology, NAD+ salvage, and epigenetic maintenance may intersect with brain health.

You are interested in a measurement-based Health Optimization Medicine approach to genetic risk.

You want to understand why phenotype, longitudinal tracking, and objective biomarkers matter when evaluating interventions.

In this episode of the Health Optimization Medicine Podcast, Dr. Ted Achacoso, Dr. Scott Sherr, Dr. Allen Bookatz, and Jodi Duval sit down to discuss what happens when the body's cellular defense systems remain activated after the original threat has passed.
Fatigue and brain fog are often treated as problems that require more stimulation, more exercise, or more supplements. But what if low energy is sometimes an adaptive response? The HOMeHOPe faculty explores the Cell Danger Response, how mitochondria and purinergic signaling respond to threats, and why pushing harder can sometimes work against recovery.
The discussion also introduces a practical three-phase approach to moving from persistent cellular defense toward greater metabolic and bioenergetic flexibility. 
Join us as we delve into:
Why Cells Get Stuck in Survival Mode: How infection, toxin exposure, tissue injury, and other stressors can shift cellular priorities toward defense, and what happens when those signals persist after the original crisis.

The Cell Danger Response: How mitochondrial function, ATP signaling, inflammation, and purinergic pathways can change during cellular stress.

Why More Energy May Not Be the Answer: Why fatigue can sometimes represent an adaptive biological response rather than simply a deficiency that can be corrected with more stimulants or supplements.

ATP Has Two Different Messages: How intracellular ATP supports cellular work while extracellular ATP can act as a danger signal through purinergic receptors.

The Three Phases of Recovery: How exposomic unburdening, assessment of intracellular and metabolic function, and reinforcement of cellular safety can provide a framework for recovery.

Measure, Don't Guess: Why organic acids, acylcarnitines, redox markers, amino acids, micronutrient patterns, and membrane lipids can help identify metabolic constraints and guide targeted interventions.

Circadian and Autonomic Regulation: Why morning light, sleep, appropriately graded activity, autonomic regulation, and circadian timing are part of restoring biological capacity.

The Limits of the Cell Danger Response Model: Where the evidence is mechanistic or emerging, why the framework should not be used to explain every chronic symptom, and why stronger clinical evidence is still needed.

This episode is for you if:
You work shifts, overnight schedules, or other situations where acute sleep deprivation is sometimes unavoidable.

You want to understand how sleep loss affects brain energy metabolism and cognitive performance.

You are interested in the relationship between creatine, phosphocreatine, ATP, and brain function.

You want to understand the potential and limitations of using creatine during acute cognitive stress.

You are interested in cellular bioenergetics and the Health Optimization Medicine approach to precision health.

In this episode of the Health Optimization Medicine Podcast, Boomer Anderson, Dr. Allen Bookatz, Dr. Ted Achacoso, and Dr. Jup Kuipers explore a misunderstood cause of chronic fatigue and leaky gut: the bioenergetic failure of your colonocytes. While many practitioners throw random probiotic strains and anti-inflammatory herbs at gut issues, metabolomic research shows this approach fails to address the root problem.
The team explains how a starved microbiome forces gut cells to switch energy systems, leaking oxygen into the colon, destroying strict anaerobes, and allowing endotoxins to flood the bloodstream and drain your cellular vitality. From holobiont metabolomics to targeted mucosal protocols, this discussion reframes gut health through the lens of mitochondrial beta oxidation rather than simply managing inflammation. 
Join us as we delve into:
The Gut Hypoxia Trap: How starved colonocytes switch to anaerobic glycolysis and leak oxygen into the gut, killing off the strict anaerobes that make butyrate.

The Endotoxemia Dilemma: How opportunistic bacteria pry apart tight junctions, allowing lipopolysaccharides (LPS) into the bloodstream and locking your cells into a permanent Cell Danger Response.

Why Probiotics Fall Short: Why conventional protocols fail to repair the mucosal shield and how to properly signal Akkermansia muciniphila with complex polyphenols.

The 4-Step Clinical Protocol: How to use stool metabolomics, pomegranate ellagitannins, oral tributyrin, and L-glutamine to rebuild the gut barrier from the ground up.

Pathogenesis vs Salutogenesis: Why Health Optimization Medicine focuses on restoring root cause physiological health rather than perpetually suppressing symptoms.

This episode is for you if:
You are dealing with chronic fatigue, brain fog, and unyielding food intolerances despite taking probiotics.

You want to understand the true biochemical mechanism behind leaky gut and systemic endotoxemia.

You are a practitioner looking to replace guesswork with objective metabolomic testing and precision mucosal protocols.

In this episode of the Health Optimization Medicine Podcast, Dr. Scott Sherr, Dr. Ted Achacoso, Dr. Allen Bookatz, and Dr. Jup Kuipers explore how acute sleep deprivation affects brain energy metabolism and whether creatine monohydrate can help preserve cognitive function when sleep loss is unavoidable.
Rather than relying on stimulants like caffeine or modafinil to push through fatigue, the team examines whether directly supporting the brain's phosphocreatine and ATP systems can maintain cellular energy and cognitive performance during acute sleep deprivation.
The discussion looks at recent research on single-dose creatine, brain bioenergetics, blood-brain barrier transport, clinical dosing, and the limits of using creatine as an acute rescue tool. 


Join us as we delve into:
Sleep Deprivation as a Bioenergetic Crisis: Why acute sleep loss is more than simply feeling tired, and how depletion of phosphocreatine and ATP can affect executive function and cognitive performance.
The Creatine Rescue Effect: What a 2026 randomized crossover study found when healthy participants received a single dose of creatine after prolonged sleep deprivation.
Creatine, ATP & the Brain: How creatine acts through the creatine kinase system to help maintain high-energy phosphates during acute metabolic stress.
The Blood-Brain Barrier Under Stress: Why sleep deprivation may change the conditions for creatine transport into the brain and create a window for acute supplementation.
The Clinical Protocol: What the episode discusses regarding single-dose creatine monohydrate, timing before an acute cognitive stress period, hydration, magnesium, and other cofactors.
Creatine Is Not a Substitute for Sleep: Why acute creatine rescue may help preserve cellular function during unavoidable sleep loss, but cannot replace the restorative functions of deep sleep and REM sleep.
Health Optimization vs. Disease Prevention: Why HOMeHOPe approaches acute physiological stress by supporting cellular function before the system reaches a state of failure.
This episode is for you if:
You work shifts, overnight schedules, or other situations where acute sleep deprivation is sometimes unavoidable.
You want to understand how sleep loss affects brain energy metabolism and cognitive performance.
You are interested in the relationship between creatine, phosphocreatine, ATP, and brain function.
