Episode Summary
This conversation originally aired on the Wolfgang Georg Sonnenburg show. You can watch the original conversation. What follows is drawn from my side of that discussion: how circadian timing, the gut-brain axis, meditation, and neurofeedback give you direct control over resources most people assume are fixed.
Does waking up early actually matter for your brain?
I do not buy the chronotype myth. The idea that some of us are born larks and some born owls, that you are better at staying up late or getting up early by nature, does not hold up against what I see in the brain maps. What matters is entrainment. Your brain performs well when it knows what time of day it is, when it stays locked to the outside world.
The strongest cues that tell your brain the time are when you eat, morning light, and morning activity. The morning carries a heavy flavor of these signals. When you get up early and train well with the sun, the amount of sleep you need tends to drop and the quality goes up. The time to sleep in is the start of the night, not the end of it. Go to bed early. There is no shame in it.
Our own circadian rhythm runs slightly longer than 24 hours (Czeisler et al., 1999). The sunlight, food, and activity signals arrive shorter than 24 hours, and that shorter signal yanks us back into the cycle. This is negative entrainment. You can catch up on lost sleep by going to bed early, not by sleeping in. The reset comes from the front end of the night.
For more on building this into a daily structure, see my piece on biohacking your morning.
Why is food timing the strongest circadian cue?
Food timing is a powerful signal to the body about what time it is, and in animal work it can shift peripheral clocks independent of the light cycle (Damiola et al., 2000). Eat in the time zone you want to live in. You can even use this for travel: shift your meal timing toward your destination a few days early and arrive with almost no adjustment lag.
The mechanism runs through melatonin and insulin. As evening comes and melatonin rises, it suppresses insulin release from the pancreas (Peschke et al., 2013). That falling insulin signal triggers snacky behavior, because evolutionarily, if you had insulin to spare, your body wanted to store the food. In a world with calories available all the time, that late snacking pushes your circadian rhythm back by several hours.
There is a growth hormone cost too. If you are north of about 35 or 40, you get one small pulse of growth hormone after you fall asleep. Any meaningful blood sugar in your system suppresses that pulse. Eat before bed and you wake up tired and hungry. Go to bed slightly hungry and you wake up energized and feeling lean.
For most people, two to three hours of fasting before bed is sufficient. If you are insulin resistant, overweight, and craving carbs, you may need a time-restricted feeding window of around six hours so that insulin can drop hard at the end of the day and reset. I cover this in more depth in strategic fasting.
How does the gut talk to the brain?
Food is not only about the body. The connection between gut and brain is direct and heavy.
The Vagus nerve, the 10th cranial nerve, is the largest nerve bundle in the body. Most of its fibers run upward, from the gut to the heart to the brain. The heart integrates this ascending gut information with descending brain information moment to moment, deciding whether you need to run, digest, or relax. The heart rate variability your wearable picks up overnight is that integration in action, the balance point between sympathetic activation and parasympathetic relaxation.
The large majority of the body's serotonin sits in the gut (Yano et al., 2015). The gut is a learning nervous system. It reacts to when you eat, and the single best predictor of when you get hungry is when you ate over the past couple of days. The body learns the schedule fast.
The practical upshot is simple: avoid eating late. The gut and brain are coupled tightly enough that food timing shapes both.
Should you skip food and coffee first thing in the morning?
When you wake, cortisol has already spiked to raise your blood sugar and heart rate and pull you out of sleep (Pruessner et al., 1997). For the first hour or two you are carrying high cortisol and elevated blood sugar relative to your baseline.
Pushing more cortisol and blood sugar into that system right away with food and coffee can blunt the signaling. The cup of coffee will not land the same way at the moment you wake as it will 90 minutes later.
I am a fan of a minimum viable morning practice. Find a 20-minute routine that feels like self-care rather than a burden, and do not skip it. Brush your teeth, do some low-key movement you can talk over, a walk or some stretching or sun salutations. Burn off the cortisol and blood sugar that woke you up first. Then when you take in coffee and food, your body hears it differently. I am as guilty as anyone of stumbling to the coffee machine first thing, so this is a discipline, not a lecture.
Do we actually have free will?
This is where the neuroscience gets squirrely. You can measure the brain reacting to the outside world before the conscious mind knows about it. The Libet experiments and many that followed show the brain picking up information and acting on it before you become aware (Libet et al., 1983). The conscious mind is not always in the decision seat. It arrives a little late in the process, which is probably the basis for intuition and other forms of non-cognitive knowing.
We are creatures of habit, learning, and socialization. Our meaning is built from our relationships and our motivated behaviors, the drives to reduce thirst and hunger and pain. The context we lay over the world differs enormously person to person. Free will would require the ability to make a choice and cause events from that choice, and most of what we experience is subcognitive: deep learning, trauma, perspective, language.
My honest position is that I am uncertain what consciousness is, let alone free will. I have watched consciousness get abolished by anesthesia and brain injury. My guess is that consciousness may be our awareness of reality collapsing into discrete moments, and we have conflated watching that happen with controlling it.
So how did you learn not to rage at the driver who cut you off?
When a driver cut you off in your twenties and you got furious, that was a threat response, a brief crisis-level reaction. Two things changed across the decades. First, your conceptual frame shifted, so you read that driver as unskillful rather than dangerous. Second, your inhibitory tone improved. You are less reactive at 40, 50, 60 than you were at 25. The ability to pump the gas and the brakes gets finer-grained as you leave your twenties.
You have also been cut off a thousand times since, with no crisis-level consequence. That repeated experience recontextualizes the event. This is the basis of how therapy works. You re-experience a stressor inside a container that is safe, and each time you retrieve and re-store the memory, the context gets updated and the event stops being a singular, charged thing (Nader et al., 2000).
If you grew up with a parent who only had a hammer, who met every stress the same way, you learned that one tool. Over a life you collect more tools, and the question of which one to reach for is partly choice and partly the simple fact that the options now exist. For more on retraining stress responses at the circuit level, see biohacking fight or flight.
Is there an age limit on learning and brain change?
No. During a decade I spent between undergrad and grad school, the field discovered that we do not stop making neurons. Adult hippocampal neurogenesis continues into old age (Eriksson et al., 1998; Spalding et al., 2013). Those neurons can resort and reconnect nearly without limit. You will never run out of brain tissue. The brain has, as far as we can tell, an effectively unlimited capacity to reorganize.
The limit is rarely the resource. It is how the resource is tuned. If you cannot concentrate, cannot sleep, cannot stay calm, function suffers, but the hardware is intact and trainable. Only about a third or less of your brain function is genetic. Most of it is learning, and learning can be changed. This is the heart of neuroplasticity.
What does meditation actually do to the aging brain?
Meditation is one of the biggest levers I know of against age-related cortical thinning. You lose a little cortex every year starting in your thirties, and the loss accelerates later in life. Long-term meditation appears to attenuate that thinning, and the effect tracks with accumulated practice (Lazar et al., 2005; Luders et al., 2009). It does not take much, roughly 20 minutes a day.
Meditation is not relaxation. Borrowing John Kabat-Zinn's frame, it is paying attention in a particular way, on purpose, to the present moment, and I would add with curiosity rather than judgment. You anchor your focus, notice when you have drifted, and return to the anchor again and again. That return is the repetition, the exercise.
It is frustrating, distracting, annoying, the same way the gym is. You are weak after a workout and strong later. Meditation builds executive function, so off the cushion you carry more inhibitory tone and more spaciousness. You are less likely to yell at the driver who cut you off, because you have that half-second to decide. That half-second of space between stimulus and response is where choice actually lives. I cover the mechanisms in biohacking meditation and in mindfulness.
Where is memory actually stored?
The standard answer is "in the brain," and that is only partly right. Karl Lashley, one of the first memory scientists, trained rats to run mazes and then progressively removed cortex trying to find where the memory lived (Lashley, 1950). He could not abolish it. He removed large amounts of tissue without erasing the memory.
Memory looks distributed and redundant. We see hints of several encoding mechanisms: the pattern of where receptors used to sit in neuronal membranes, the weighting between neurons that makes one more likely to fire the next. The information may not be stored discretely in one place. Think of remembering a song not as a fixed series of notes but as a mathematical arrangement, an algorithm, held as a resonant pattern across many cells. This holographic model explains why losing physical tissue costs you resources like language or production, but rarely individual memories.
There are also case studies of heart transplant recipients waking with cravings, fragments, and reactions that trace to the donor. The heart has neurons similar to brain neurons, though they regulate differently. A healthy heart runs as a coherent waveform, and a healthy brain runs chaotic and oscillatory. When a brain goes coherent, that is a seizure; when a heart goes chaotic, that is a heart attack. Whether the heart stores information is genuine speculation on the current evidence, and the neuroscience has not caught up to the case reports yet.
What can neurofeedback actually change?
The functional way I think about the brain: there are about six to eight regulatory resources, features that are meant to change and that rise to meet demand. They include attention, the anxiety-flavored states, sleep, speed of processing, stability (seizure and migraine resistance), and sensory and social processing. These are trainable. They cramp up and dysregulate, and that is where a lot of human suffering lives.
You can measure these resources on a QEEG brain map: a cap, some gel, and resting data. If your alpha speed is dragging slow and you are having word-finding trouble and tip-of-the-tongue moments, you can see it. If your delta suggests poor sleep, or your beta shows anxiety slowing your processing, you can tease those apart. Then you exercise the brain waves directly with neurofeedback.
The conditions where the research is strongest, and where I see resources move fastest in the maps, include ADHD, anxiety, seizure, migraine, PTSD, and OCD. With ADHD and anxiety the protocols typically run three or four months, and over that window the research and my own observation point to meaningful, durable change in executive function, sleep, and anxiety. The randomized literature on epilepsy reports roughly a 50% reduction in seizure frequency on average (Tan et al., 2009), and in the maps and reports I have followed the reductions have tended to run larger than that. To be clear, these are statements about what the research shows and what I observe across brains, not a treatment promise for any one person.
How a session works at the circuit level: there is a circuit on the right side of the brain involved in executive function that uses beta waves to do its job and slides into automatic modes on theta. Too much theta there and you are distractible, impulsive, the squirrel pattern, and you do not fall asleep well either. Stick a sensor over that site plus a couple of ear clips, measure beta and theta in real time, and whenever the brain moves the right direction for half a second, you applaud it with sound and visuals. When it moves the wrong way, the feedback slows or stops. The trick is moving the goalposts every few seconds so the applause only fires for that one circuit flexing correctly. You cannot feel your brain waves, so this is mostly involuntary. This is operant conditioning of brain electrical activity. Two or three sessions in, people start to feel a flicker of focus, and with repetition it stops wearing off.
This is the same creativity and access work we use for the hypnagogic state, that moment falling asleep where the monkey mind drops and insight surfaces. You can train reliable access to it. The same protocol also helps long-term alcohol users. Years of drinking shifts GABA and glutamate signaling, and in the absence of alcohol you are left with a shaky, over-glutamatergic brain that cannot bring glutamate back down (Tsai & Coyle, 1998). Six to ten weeks of neurofeedback and many people report the craving eases and sleep returns. I describe the conditions and the evidence in more depth in my guides on neurofeedback for ADHD, neurofeedback for anxiety, and SMR neurofeedback.
Do you have to visit a clinic to do neurofeedback?
Most of our clients in the US never visit an office. We send equipment home. The training rig is small: a micro EEG amplifier, a couple of ear clips, a couple of wires on the head, measuring the brain in real time. In Europe and the UK people come in once for the assessment and brain map, then take equipment home.
People run three or four workouts a week, half an hour each, with live coaches available seven days a week to set up the gear and cheer them through it. Think of it as the gym model: you have goals, you do not know how to set the machine, and someone sees your confusion and helps you dial it in. We have offices in Stockholm and London and several in the US, and we work remotely with clients in Canada, Australia, and Dubai. If you want to see how distance training works, I cover it in remote neurofeedback.
The full course is real work. Many people need 30 to 60 sessions, sometimes more, to reach their goals, so plan for a few months even at half an hour a few times a week. The improvements in anxiety, attention, and sleep that people report are strong and hard to ignore, and they reflect genuine circuit-level change rather than symptom management. Worth saying plainly: not everyone responds. A non-response rate of roughly 15 to 30% is normal, and any honest program builds in re-mapping and off-ramps rather than selling a guaranteed outcome.
Why does seeing your brain on a map change anything?
When you see your suffering in data, in a brain map or in performance testing, it does not erase the suffering in that moment. What it does is make it much harder to feel ashamed or guilty about it. You look at the map and see an adaptation of your brain rather than a personal failing. You do not feel guilty about a broken shoulder on an x-ray. You are frustrated, the pain is there, but you do not blame yourself for it.
With the brain, we tend to assume it is our fault, that it is happening to us, especially when a diagnostic label has been applied from the outside. A label can obscure how much control you actually have, because it lands top-down instead of showing you how your individual resources work. Knowing yourself in this specific, measurable sense puts you in the driver's seat.
The practical takeaways
Start with circadian timing, because it is free and it moves the most. Stop eating two to three hours before bed. Hold off on food and coffee for the first 60 to 90 minutes after you wake, and do 20 minutes of low-key movement first. Build a daily meditation habit of around 20 minutes to protect your cortex over the decades. And if you have a regulatory pattern that has resisted everything, ADHD, anxiety, PTSD, OCD, poor sleep, a QEEG map will show you what is actually happening, and neurofeedback can train those resources over a matter of months. Your brain keeps making neurons and keeps reorganizing for your whole life. The change is available whenever you decide to go after it.
