Emotions as Physiology
The Biochemistry of Feelings

There is a moment that catches nearly every serious practitioner of the Primal Diet off guard. The diet is working. The digestion has stabilized, the chronic pain has receded, and the body is clearly doing something productive. Then, without warning and without any apparent cause in present life, a wave of panic arrives. Or rage. Or grief so specific it carries the texture of something that happened thirty years ago. The instinct, shaped by decades of psychological culture, is to call this a breakdown. To look for the precipitating event, the unresolved wound, the repressed memory that therapy has not yet reached. To reach, perhaps, for a prescription.

Aajonus Vonderplanitz spent decades arguing that this interpretation is precisely backwards. The panic is not a psychological crisis. The grief is not a sign that healing has stalled. What the person is experiencing, in his framework, is biochemical elimination. The body has finally accumulated enough raw material to begin dismantling the stored residue of old trauma, and that residue, as it circulates on its way out, produces the same emotional signature it produced when it was first manufactured.

The central claim of this framework is one that the prevailing psychological culture has not yet absorbed, despite the fact that the underlying biochemistry has been documented with considerable rigor: emotions are not abstract psychological events. They are physiological processes that generate specific neurological hormones, and those hormones produce waste products that the body stores exactly as it stores any other toxin. When detoxification reaches those stored compounds, the individual re-experiences the original emotional state, not because the psyche is unresolved, but because the chemistry of that state is literally re-entering circulation. Happiness is not a mental achievement. It is a nutritional condition.

The scientific foundation for this claim belongs largely to Dr. Elnora Van Winkle, a biochemist who spent nearly fifty years at Milhauser Laboratories, affiliated with Columbia University and New York City Medical Center, cataloging every chemical compound present in the human brain and nervous system. Her work, published in accessible form as "The Biology of Emotions," is not widely cited in clinical psychology, but its implications are substantial. Van Winkle documented that the production of neurological hormones during periods of trauma, anxiety, or intense stress generates byproducts, in the same way that any metabolic process generates byproducts, and that these byproducts store in the body's tissues when the individual's health is insufficient to eliminate them in real time.

What Van Winkle found, through direct observation of her research colleagues and friends, was that when a person became emotionally destabilized without any identifiable external cause, her blood analysis revealed these stored psychotropic byproducts circulating at elevated levels. As Aajonus described it in his workshops, Van Winkle "used the word whacked out, this is a scientist used the word whacked out. She said whacked out emotionally when there was nothing directly that happened in her life, in that woman's life, she would get like that. She found these psychotropic hormones in her blood as waste products, cleaning out from a previous time, could have been when her father intimidated her and ridiculed her or something like that as a child and then she takes that out on her husband 40 years later."

The mechanism Van Winkle identified maps directly onto what Aajonus had observed empirically in his patients and in his own body: the stored compounds, wherever they are lodged in fat tissue, bone marrow, or brain, re-enter circulation during detoxification and produce an emotional state chemically identical to the one in which they were created. A person in their forties who experiences a surge of childhood panic during a period of dietary detoxification is not having a psychological regression. The panic is the compound. The compound is leaving.

This is not metaphor. It is, in Van Winkle's framework and in the framework Aajonus built from her findings, measurable biochemistry. The emotional state is a downstream effect of circulating chemistry, not a signal from the unconscious. The pathway runs from stress to neurological hormone production, from hormone production to psychotropic waste generation, from waste generation to storage in fat tissue, and from fat tissue to re-circulation during detox, with the original emotional signature intact.

One of the most clinically precise elements of Aajonus's framework concerns the relationship between adrenaline, fat, and the nervous system's physical structure. Ninety percent of anxiety, he argued, is caused not by psychological factors but by a straightforward physiological imbalance: the body produces hormones for physical activity, particularly adrenaline and related compounds, that are never spent through actual movement. These hormones circulate without being metabolized, and in the absence of sufficient fat in the blood to buffer them, they begin consuming the myelin sheath, the protective fatty coating that surrounds nerve fibers and accounts for roughly ninety percent of their composition.

Myelin degradation produces a constellation of symptoms that the psychiatric literature typically attributes to psychological causes: hypersensitivity to sensory input, irritability with no identifiable source, cognitive fog, difficulty with sustained attention, and a pervasive sense of agitation. When the nervous system's insulation thins, everything becomes too loud, too bright, too abrasive. The person is not anxious because of their thoughts. The person is anxious because their nerve sheaths are deteriorating in the absence of adequate fat, and raw cream, in Aajonus's clinical observation, settles the nervous system faster than any other intervention.

He was precise about the distinction between anxiety and depression because the physiological roots differ. "If you're anxious, that's a matter of exercise. That means you're producing a lot of hormones for physical activity, and you're not expressing them in activity." The remedy is movement, not medication. The adrenaline, testosterone, and estrogen produced for muscular engagement need to be discharged through muscular engagement. No pharmaceutical intervention addresses this mechanism because no pharmaceutical intervention puts the hormones to use. It simply suppresses the signal that the surplus exists.

The distinction matters because depression, in Aajonus's framework, has an entirely different physiological root. The large intestine is colonized predominantly by E. coli, a bacterial species that the medical establishment spent two decades vilifying on the basis of rare pathogenic strains while ignoring the critical metabolic function of the far more prevalent beneficial populations. E. coli in the colon breaks down fat and protein molecules into their smallest particles, the finite molecules that cross into the bloodstream and feed the brain and nervous system directly. Without a robust E. coli population, the brain is not being fed at the resolution it requires.

Aajonus was unequivocal about the arithmetic: ninety-five percent of depression, in his clinical observation, originates in low bacterial levels in the colon. The brain is starving at the molecular level. No amount of serotonin reuptake inhibition addresses this deficiency, because the problem is not serotonin transport. The problem is that the bacterial population responsible for manufacturing the finite nutrient particles the nervous system depends on has been depleted by antibiotics, enemas, processed food, chlorinated water, and the general chemical assault of contemporary life.

The intervention Aajonus advocated was high meat, bacterially decomposed raw meat, which delivers pre-digested amino acids and concentrated bacterial cultures directly to the digestive system. As he described it, "eating an ounce of high meat usually relieves depression in 10-20 minutes and may last for weeks." The mechanism is not mysterious. The bacteria in high meat have already completed the work that a depleted colon cannot. The finite molecules arrive ready for absorption, and the brain begins receiving adequate nutrition almost immediately. He documented cases in which decades of psychological depression resolved within hours of consistent high meat consumption, not because of any psychological intervention, but because the nervous system was finally being fed.

Cryan and Dinan's landmark 2012 paper in Nature Reviews Neuroscience, examining what researchers had begun calling the gut-brain axis, documented through controlled research what Aajonus had been observing clinically for decades: gut microbial composition directly influences mood, anxiety, and cognitive function. The relationship is not indirect or speculative. Specific bacterial populations generate specific neurochemical precursors, and disruptions in those populations produce measurable changes in emotional states. The paper did not endorse high meat, and its authors were working within a conventional research framework, but the fundamental principle they established, that emotional states have physiological and specifically microbial determinants, is exactly the principle Aajonus had been applying.

The dietary intervention Aajonus developed for the stored psychotropic byproducts of trauma is specific in its mechanism. Starch, he found, is the only substance capable of binding with these circulating compounds during detoxification and arresting their damage to the nervous system. Grains do not accomplish this. Beans do not accomplish this. The substance that works is the starch found in soft nuts, particularly walnuts and pecans, when prepared in a specific way.

Ground to flour and combined with raw eggs, raw butter, and unheated honey, the nuts provide starch that binds with psychotropic waste products and hormone byproducts while the other components neutralize the phytic acid that would otherwise interfere with mineral absorption. The formula targets the compounds Van Winkle identified, specifically the circulating byproducts of neurological hormone production, and provides the binding substrate they require for elimination without the acrylamides and advanced glycation end products that cooked starch generates.

Aajonus was careful to note the hierarchy of interventions: ninety-five percent of psychological problems respond to the bacterial approach, to high meat and the restoration of E. coli populations. The remaining five percent, those cases where the primary issue is stored psychotropic byproducts from trauma rather than bacterial deficiency, require the nut formula. Used once a week, it prevents the accumulation of these compounds from reaching symptomatic levels. Used during active detoxification, it attenuates the emotional intensity of the re-experiencing process.

He had also observed the edge cases, the person who consumes high meat and finds that depression worsens rather than resolves. This is a diagnostic signal, not a failure of the protocol. When high meat intensifies rather than relieves depression, it indicates that the dominant mechanism is psychotropic byproduct accumulation rather than bacterial deficiency. The bacteria in high meat have nothing to do with the psychotropic compounds. Those compounds require starch binding, not microbial pre-digestion. The intervention shifts from the bacterial track to the nut formula track, and the depression resolves.

There is scientific evidence that Aajonus cited with evident satisfaction, because it validated through conventional research a principle he had arrived at through observation: crying does not merely express emotional states. The act of crying transforms specific toxins in the brain into endorphins, which are then eliminated through the tear ducts. The mechanism converts neurological waste into a benign form for excretion through a pathway specifically adapted to that purpose.

This reframes the cultural conversation about crying entirely. The permission to cry, the therapeutic emphasis on allowing emotional expression, may be inadvertently correct for entirely wrong reasons. The psychological interpretation holds that crying releases repressed feeling. The physiological interpretation holds that crying releases actual chemical compounds through a specialized excretory pathway. Both may produce benefit, but only one of them identifies the mechanism accurately, and only the accurate identification suggests the correct clinical response. If crying is neurological detoxification, then suppressing it, whether through medication that blunts emotional reactivity or through cultural pressure to maintain composure, actively prevents elimination of toxic compounds from the brain.

Aajonus was direct about his own practice. He cried regularly and considered it beneficial without embarrassment or qualification. The mechanism he described, in which neurological proteins identified by Van Winkle are transformed and discharged through tear production, treats an act of emotional expression as an act of physiological cleansing. They are not mutually exclusive categories. They are the same event described at two different levels of resolution.

Aajonus's divergence from Van Winkle was pointed and principled. She believed in primal therapy, the practice of acting out emotional states during detoxification, screaming, kicking, physically expressing the anger or grief or panic that the circulating compounds produce. He disagreed, not because the compounds are not real or the emotional intensity is not genuine, but because the practice creates more of the same compounds it is attempting to eliminate.

As he explained it directly: "if you release angst with angst, you will keep living in angst." The rage produced during a primal therapy session is physiologically identical to the rage that created the original stored compounds. Acting it out is not releasing it. Acting it out is manufacturing more of it, which stores in the body and extends the cycle. He watched this pattern over years of observing patients who pursued primal approaches and found that the emotional turmoil maintained itself rather than resolving.

His own experience with the primal therapy movement of the 1970s confirmed this. When he went through his own detoxification of psychotropic compounds, including those stored from forced medical injections, the experience was severe, "horrible mind-altering chemicals" leaving the body, "nerves jumping," severe agitation, states of attention deficit that made ordinary function difficult. The temptation to discharge this energy through rage or confrontation was understandable. The result of doing so, he found, was more stored material, not less.

His alternative was to redirect rather than discharge. Singing, dancing, painting, any creative activity that transforms the energy driving the emotional state into something generative. The energy itself is not the problem. The body has produced a surplus of emotional hormones, and those hormones represent actual physiological force that needs somewhere to go. Directing them toward creative production does not generate additional psychotropic waste. It converts the hormonal surplus into output that leaves the system cleaner rather than more burdened.

The contrast he drew was between two ways of handling the same physiological event. Both acknowledge the reality of the emotional intensity. Only one of them breaks the cycle.

The objection arises, reliably and not unreasonably, that this framework reduces the full complexity of human emotional life to chemistry. That it is reductive. That it diminishes the significance of experience, of memory, of the relational wounds that shape a person's psychology over a lifetime. That a person's grief deserves more than a prescription of high meat and a nut formula.

The objection misunderstands what the framework claims. Understanding that emotions have a biochemical substrate does not diminish their reality, their significance, or their relationship to actual experience. The person who stored thirty years of anxiety in their bone marrow did so because thirty years of real events produced real neurological hormones that generated real psychotropic waste. The experience was genuine. The storage is the record of its genuineness. The detoxification is the body finally having enough capacity to process what it could not process in real time.

The clinical point is this: the person who has spent a decade in competent, thoughtful psychotherapy without resolving their chronic anxiety may find that the anxiety was physiological rather than psychological in its dominant mechanism. Not because the therapy was wrong, not because the therapeutic relationship was without value, but because the anxiety had a material substrate that insight alone cannot address. Aajonus made the case plainly: "Unless physical health is restored, psychotherapy of any kind is not likely to be complete or long-lasting."

The decade in therapy and the adequate raw fat and high bacterial population are not in competition. They are operating at different levels of the same system. But when the physiological substrate is unaddressed, the psychological work is being done on terrain that actively resists resolution. The person keeps regenerating the chemistry of the emotional state they are attempting to process. They are running a detoxification deficit, producing new psychotropic waste faster than they can eliminate the stored material, and the therapeutic work, however skillful, is addressing the downstream expression of an upstream biochemical imbalance.

The most direct statement of this principle appears in Aajonus's own words: "When you get enough fats and proteins in the body, things will start making you happy. Otherwise, with this kind of imbalance and instability in the body, nothing will make you happy. I don't care if you got the greatest guy in the world and had the most money. It would be impossible to be happy because that whole body is so dry inside."

That observation, offered not as philosophy but as clinical finding, is the most honest account of what biochemical deficiency does to emotional life. It removes the capacity for happiness at the substrate level. No relationship, no insight, no spiritual practice, no amount of positive cognition can compensate for a nervous system that lacks the fat to protect itself, the bacteria to feed itself, and the raw materials to eliminate its stored burden. The prerequisite for emotional wellbeing is not psychological. It is physiological. The terrain determines the range of what is possible. When the terrain is adequate, the emotions follow.

Emotional healing is biochemical. But beneath the biochemistry, beneath the diet, the lifestyle, the political fight, Aajonus operated from a philosophical orientation that gave all of it meaning. It was not positive thinking. It was not religious faith. It was something harder and more honest.
