About the bioenergetic frame.
A short orientation to what this site is about, who it draws on, and what to expect.
The bioenergetic frame is a particular way of looking at physiology and disease. The modern medical default looks first at receptors, neurotransmitters, and pathways. The bioenergetic frame looks first at whether cells can make enough ATP. Almost every chronic complaint a thoughtful person notices in themselves (fog, low motivation, blunted digestion, cold extremities, fragile sleep, slow recovery from stress) sits downstream of that one variable.
When the cell's mitochondria have what they need (oxygen, glucose, thyroid hormone, the small handful of cofactors at the heart of respiration), most things work. When they don't, things start to fail in a predictable order. The flagship article on this site, Brain fog is an energy problem, walks through one such cascade end-to-end.
The strongest single statement of this position came from Otto Warburg, the biochemist who won the Nobel Prize in 1931 for figuring out how cells respire. Decades later he wrote that the prime cause of cancer is the replacement of the respiration of oxygen in normal body cells by a fermentation of sugar. The specific claim about cancer is contested. The general posture, that disrupted cellular respiration is upstream of disrupted everything else, has held up well across forty more years of research and forms the foundation of this site's perspective.
01 · lineageThe intellectual lineage
Three names recur in these essays. None of them are household; all of them are worth knowing if you want to read more deeply on your own.
Otto Warburg (1883–1970)
German biochemist, Nobel laureate. Established that cells produce ATP via oxygen-driven respiration in mitochondria, and that when respiration falters they fall back to glucose fermentation in the cytosol, yielding 2 ATP per glucose instead of 30+. The "Warburg effect" in cancer biology is named for his observation that tumor cells preferentially ferment, and it remains an active area of research a century later.
Albert Szent-Györgyi (1893–1986)
Hungarian biochemist, Nobel laureate (vitamin C). Wrote Introduction to a Submolecular Biology (1960) and Bioenergetics (1957). His most quoted line is the cleanest one-sentence summary of the entire frame:
Life is driven by nothing else but electrons, by the energy given off by these electrons while cascading down from the high level to which they have been boosted up by photons. Albert Szent-Györgyi, Introduction to a Submolecular Biology (1960)
Ray Peat (1936–2022)
American biochemist who spent four decades publishing essays applying Warburg and Szent-Györgyi's frame to thyroid, hormones, nutrition, and chronic disease. His work is the most comprehensive practical synthesis of the bioenergetic position. It is also, to put it gently, not optimized for casual reading. Most essays here owe more to Peat than to anyone else, even where the wording is mine. His complete archive is at raypeat.com.
02 · pillarsWhat this site publishes
Four pillars, roughly in priority order:
- Cellular energy and cognition. How brain and nerve tissue specifically suffer when ATP is short. The flagship essay sits here. Cluster topics: thyroid, mitochondrial membranes, breathing and CO₂, lactate, dopamine.
- The gut-brain axis. How endotoxin, bile, fiber, and the gut microbiome shape every other system. Cluster topics: lipopolysaccharide (LPS), gut serotonin, mast cells and histamine.
- Stress physiology. How cortisol, progesterone, estrogen, and adrenaline modulate the same metabolism. Cluster topics: HPA axis, cortisol catabolism, neurosteroid protection.
- Practical bioenergetics. Reading thyroid panels, choosing fats, breathing as an intervention, and the small handful of cofactors that gate ATP production.
Each essay has at least one custom diagram. The visual style borrows from books like Atomic Habits: one core idea per figure, generous whitespace, minimal labels. Each substantive mechanism claim has a citation. Every essay links back to the flagship and out to relevant essays in other pillars; over time the site becomes a navigable map of the frame rather than a flat list of posts.
03 · readingWhere to start
If this is your first visit, start with Brain fog is an energy problem. It runs about 8 minutes and walks the entire frame end-to-end through one set of symptoms most people recognize. Once you have read that, the topics in any of the four pillars sit in context.
The publishing schedule is one essay every Monday. Sources are listed at the foot of every essay; outbound links go to Peat's archive, the original Warburg and Szent-Györgyi books, and standard physiology textbook references. Where I am uncertain, I say so. Where the bioenergetic position is contested or non-canonical, I flag it. The goal is to give a thoughtful reader enough context to decide what to investigate further on their own.
This is a reading framework, not medical advice. The bioenergetic perspective is one lens on physiology among several. Take it as something to test against your own reading and your own experience.
