The Crucial Chemistry of Methylation
At the foundation of human biochemistry is a microscopic process called cellular methylation. This process acts like a software program inside your cells, transferring small chemical units—methyl groups—billions of times every second.
Methylation governs how your body repairs DNA, detoxifies impurities, processes brain chemicals like your neurotransmitters, and manages cellular energy. When it runs smoothly, your liver clears metabolic waste effortlessly, and your body stays resilient. Having insight into our individual methylation status is therfore crucial for good health. When we understand our baseline methylation status we can make micro-adjustments to our diet and lifestyle to help keep everything in balance. Thankfully, even without genetic testing we can get an idea of where we fall on the methylation spectrum by considering the following:
The Functional Undermethylator: The Sluggish Traffic Jam type
Functional undermethylation occurs when this chemical process runs behind schedule, often due to a lack of available methyl groups, for example a vegetarian diet when it does not suit our system. This slow pacing creates a backlog of raw compounds in your tissues, starving your mitochondria of active fuel.
Traits and Strengths: The Undermethylator (The Strong-Willed Finisher): Rather than standard abstract creativity, the undermethylated matrix (histadelia) is defined by a rigid, relentless drive. They are characterized by high achievement, competitive perfectionism, and obsessive-compulsive traits. They do not typically thrive on loose, artistic, open-ended night-owl schedules; their brains rely on structured, ritualistic behaviours and poor concentration blocks that leave them exhausted if they try to push into the small hours without a rigid frame. If maths or history were your favourite subjects at school and you are prone to depressive thinking and you can't work past 10pm even though there's a job needs finishing, then this might be you. You simply don't have the high levels of neurotransmitters, dopamine, serotonin and adrenalin needed to keep you going past bedtime.
Systemic Feedback: When neurotransmitter recycling slows down, it can manifest as low-energy slumps, cyclic patterns of low mood or depression, and a vulnerability to seasonal allergies due to elevated histamine levels (not enough methyl donors to break down histamine levels)
Dietary Support: This baseline thrives on clean, high-purity protein matrices. These provide the essential sulphur and methyl groups needed to naturally accelerate the chemical pathway without placing a processing drag on digestion. Animal protein is a rich source of methionine which our bodies use as a source of methyl donation which the undermethlator type needs in abundance.
The Functional Overmethylator: The Accelerated Engine type
Functional overmethylation occurs when the cellular system generates an abundance of methyl groups, running its biochemical software at an accelerated velocity. This hyper-accelerates neurotransmitter turnover, altering how the nervous system handles daily stress.
Traits and Strengths: The Overmethylator (The Night Owl & Artist):. In the Walsh Protocol, functional overmethylation is the true home of classic artistic, musical, and expansive abstract creativity. Because their biochemical software runs at a highly accelerated velocity, their nervous systems carry massive internal tension and high neurotransmitter turnover. This hyper-frequency allows them to dynamically hyper-focus and work straight into the small hours of the morning while others have completely flatlined for the night. This matrix is characterized by highly sensitive, empathetic, and intuitive thinking patterns. These individuals possess a high capacity for expansive, big-picture, and artistic creativity. If art or languages were your favourite subjects at school and your are prone to anxiety complete with trembling and you can work until early morning on an interesting project when everyone else has faded away, then this type is probably you. You have such high levels of the neurotransmitters, dopamine, serotonin and adrenalin that you can continue a piece of research (as long as it's your favourite subject) until way past bedtime, but the price is high as once these run out you will crash in the days and weeks to come.
Systemic Feedback: Because the internal software runs at a high frequency, the nervous system can easily tip into hyper-stimulation. This manifests as situational anxiety, a feeling of being constantly "wired but tired," and a tendency for muscles to lock into defensive bracing loops.
Dietary Support: Balancing this profile focuses on steadying the biochemical pace. This baseline responds beautifully to an abundant scaffolding of complex, unrefined carbohydrates, green leafy vegetables and pulses. Things can go very bad for the overmethylator if they try and do a high meat or ketogenic diet because their systems are already flooded with methyl groups and ingesting more from methionine (the main amino acid in animal meat) can cause the overmethylator numerous unpleasant symptoms including a racing mind, racing heart, restless legs, anxiety, some serious mental health disorders in extreme cases and cold clammy skin - all symptoms of an excess of the neurotransmitters serotonin, dopamine and adrenalin.
If you were the School Prefect, the Head Boy and the Teacher's star maths pupil you are probably an undermethylator. If you were that pupil that only turned up for pottery class and the rest of the time put clingfilm over the boy's toilets after getting thrown out of a Physics class, then you are more likely an overmethylator. If you didn't fit either of these categories then you are probably one of the 50% of the population with an ideally balanced methylation status who breezed through life with good health and good grades.
