On a recent Neurofeedback & Chill livestream I shifted away from the usual single deep-dive and laid out my top five biohacks across the categories I keep coming back to in coaching and in my own routine. People who read the biohacking guides on this site have told me there is a lot in there and they want to know where to start. This is my answer. Five high-leverage areas, the mechanism behind each, and one morning practice that folds most of them into a single 20-minute habit.
A quick note before the list. Many of the goals here can also be trained directly with neurofeedback, and a QEEG brain map is still my biggest single biohack because it tells you where to apply pressure. If you understand your own brain, the data points you toward the intervention that fits your sleep, stress, attention, or processing speed. You read your brain the same way you read a lipid panel or your blood pressure. The number itself gives you agency.
What does sensorimotor rhythm training do on the right side of the head?
I usually open these streams running a live neurofeedback session, and that night I trained SMR at C4 referenced to the left ear. C4 sits over the right precentral gyrus. That region handles supervisory tone of attention, the part of you that notices whether you are actually paying attention, reads the map, and decides when to slow down for the turn.
The setup tells you what the brain is doing. I rewarded sensorimotor rhythm, 11.75 to 14.75 Hz, and inhibited two bands around it. Below SMR is theta, 4 to 8 Hz, a disinhibition frequency that takes the brakes off. A specific theta band around 6.5 Hz may carry insight and the sudden-memory "aha" release. Too much theta at rest, though, looks like ADHD, so on a supervisory circuit you generally want it to come down. Above SMR I inhibited fast beta, 22 to 34 Hz. The training itself runs through operant conditioning below conscious awareness. The game moves when your brain holds the target pattern for half a second and stops when it drifts. You do not steer it on purpose. Over a 30-minute session the brain gets roughly 2,000 small rewards and uses those samples to nudge itself in a direction. If you want the details on this band, I wrote them up in SMR neurofeedback.
Now to the five.
Why is circadian timing the most important biohack?
Sleep is the whole nocturnal cycle, not just the hours you spend unconscious. It is your brain's ability to read its internal clock and lock it to the Earth's photoperiod, night after night. When your own rhythm slides past the external day, you get real consequences: seasonal affective patterns, daytime sleepiness, disrupted sleep architecture. Get this dialed in first.
Here is the mechanism that surprises people. To shift an oscillating system, you work against the rhythm, not with it. Push with the rhythm and you change its size; push counter to it and you change its timing. That is why morning cues are more powerful than evening ones for moving your clock. Three moves do most of the work:
- Lock an early wake time every day regardless of when you fell asleep.
- Go to bed fasted by a couple of hours. High blood sugar at bedtime suppresses growth hormone and blocks deep sleep.
- Move gently in the morning before food, before coffee, before you sit down.
That third point connects to two of the other biohacks below. If you want the full version, read biohacking your morning and biohacking sleep.
How does meditation change the brain over weeks and months?
Mindfulness is not relaxation and it is not blanking the mind. Most of the time when you sit, the mind is busy and noisy. The work is anchoring attention in a chosen way, then re-anchoring it every time you notice you have drifted. Repeat that across weeks and months and you get stability, stillness, and less reactivity as a downstream result.
There is good evidence that regular practice supports healthy aging. Consistent meditation thickens the prefrontal cortex and helps you sidestep some of the normal cortical thinning that comes with age. Start small and build up. I have a 10-to-20-minute guided meditation on the site, and the mindfulness article and biohacking meditation go deeper into the mechanisms.
Why does morning movement matter more than the workout itself?
Being sedentary across days is genuinely dangerous for the cardiovascular system. Move routinely: take the stairs, park further out, use a standing desk, get up every 25 to 30 minutes for a short walk, stretch your legs every couple of hours.
The timing point is the one most people miss. Cortisol and blood sugar both rise right before you wake, so you surface in a high-cortisol, high-glucose state. Hit a hardcore workout or start eating immediately and you stack stress and energy onto a system already loaded with both, which makes the circadian signals harder to hear cleanly. Wait an hour before food or coffee and use that first hour for gentle, low-key movement: tai chi, walking, easy yoga. That burns off the morning cortisol and glucose and gives the clock a clean cue.
How much protein do you actually need, and why?
How you eat feeds back into the same circadian, cortisol, and insulin signaling. Not eating before bed is the single strongest external cue for circadian rhythm. A lower blood sugar at sleep onset means better growth hormone release and more deep sleep from the same hours. So when you eat carries real weight.
On fasting, the evidence leans toward total calories mattering more than the fact of fasting itself, but early time-restricted eating, putting a three-to-four-hour fast at the end of the day, looks more useful than skipping breakfast. Add a few hours of fasting at night and let your onboard energy deplete in the morning before you reach for food. The strategic fasting article covers the time-restricted side in detail.
Protein is where most people are short. Aim for roughly a gram per pound of ideal body weight for men and a little under that for women. Protein creates satiety and stable energy without the insulin swings that drive snacking and sugar cravings. It protects muscle even in a mild caloric deficit. Your body can convert protein to glucose through gluconeogenesis, but only on demand, as blood sugar falls and there is a real signal for it. The process is inefficient, so eating protein in a non-excess state does not quietly turn into stored fat. Unused protein mostly gets excreted.
Two practical guardrails:
- Manage deficits weekly, not daily. A genuine fasting day beats a grinding 500-to-1,000-calorie-a-day deficit held for weeks. A deficit that looks aggressive on a single day can be moderate across the week. Women's bodies adapt faster, so getting enough protein plus morning movement matters more for preserving metabolism.
- Get carbs from whole foods. Carbohydrate is not an essential nutrient the way protein is, but fruit and fiber-rich vegetables carry the micronutrients, fiber, and the water-and-mineral matrix you need. It is hard to overeat carbs from broccoli or apples; the fiber moves them through you. I have cooled on the carnivore approach for that reason.
A word on electrolytes, since a viewer asked. When you run low-carb, you waste water. Each gram of stored glycogen holds roughly three grams of water, so as glycogen drops, water leaves, and it carries electrolytes out with it, especially calcium and magnesium. That is why low-carb athletes get calf cramps that wake them at night, plus palpitations and gut issues. Whole-food carbs at 50 grams or so give you a matrix to retain water and minerals along with the micronutrients. For shopping: short ingredient lists you understand, and cook for yourself when you can.
What single morning practice stacks all five biohacks?
This is the minimum viable practice, the MVP. Learn the sun salutation, the traditional sequence of poses linked to breath and gaze. After a couple of days it becomes overlearned, and once the movement is automatic you can actually meditate inside it. Do five sun salutations, roughly 10 to 15 minutes even when you are slow and clunky like me. Add the longer, more taxing Surya Namaskar B once you are ready and run five of each, and the whole thing lands around 20 to 25 minutes.
Look at what that one habit covers. You get the morning movement that burns off cortisol and glucose. You get a meditative anchor through the repetition of breath, gaze, and pose. You reset the circadian clock with early movement before food. And it enforces the nutrition rule by default, because you cannot do gentle morning yoga bloated and lethargic from a heavy late dinner. One practice, most of the stack, done before you start your day.
If you want to train any of these targets directly rather than only through behavior, that is where a brain map and neurofeedback come in. The data shows you which circuit to work, and the rest of the biohacks build the scaffolding around it. Pick one of the five to start with this week, and add the morning sun salutations once it holds.
