The terrain — the most powerful hack is a return
The word “biohacking” often evokes gadgets, sensors, rare powders. The truth is gentler and more radical: our body is not a system to be hacked, it is an already perfect technology whose signals modern life has simply cut off. Too little sun, too much light at night, never any cold, never any hunger, never any true breath. The most intelligent biohacking does only one thing: it plugs these signals back in.
This is the path championed by Gary Brecka, the American biohacker who repeats one simple phrase: the body is not broken, it is depleted. Before any sophisticated protocol, he brings everyone back to the foundations — oxygen, morning light, water, minerals, breath, contact with the earth. Fill the base before stacking the summit. That humility is the greatest ingenuity of all.
We do not seek to become more than the body. We seek to give it back what the modern world has taken from it — and to watch it recover, on its own, its full power.
The sun — the first clock
Before being a source of heat, the sun is information. Morning light, received in the eye within the first hour of the day, sets our internal clock: it triggers the waking cortisol at the right moment and programs, twelve to fourteen hours later, the release of melatonin that will open the door to sleep. Ten minutes outdoors upon waking, without glasses or a window pane, are worth more than any supplement.
Morning light
Step outside within the first sixty minutes after waking, even under a cloudy sky (the outdoors remains ten to a hundred times brighter than a room). It is the gesture that anchors the entire rhythm of the day.
Vitamin D, the sun's hormone
On exposed skin, the sun turns cholesterol into vitamin D — in truth a hormone that speaks to thousands of genes, supporting immunity, mood and bone strength. A few minutes of sun on the forearms and face, at safe hours, are enough to keep the reservoir filled.
Darkness, the other half
Bright evening light — screens, ceiling lights — erases melatonin and delays sleep. Lowering the lights after sunset, favouring warm and low sources, gives the night back its signal. Sun and darkness are one clock with two hands.
Sleep as technology
Sleep is not an absence: it is the nightly workshop where the body repairs itself, where the brain washes away its waste and files memory. We do not force it, we invite it — by gathering four conditions the body recognises.
- Coolness: a bedroom around 18°C helps the core temperature fall, the very condition of falling asleep.
- Total darkness: the slightest point of light disturbs melatonin; complete darkness is a nutrient.
- Regularity: going to bed and rising at the same hours sets the clock better than any device.
- An evening of calm: a soft, early dinner, no aggressive screens, lets adenosine rise and the breath slow.
Neurotransmitters — and how to feed them
Our inner states — drive, calm, focus, joy — rest upon a few messenger molecules. And these molecules do not come from nowhere: they are built from amino acids we eat, with the help of cofactors (B vitamins, magnesium, vitamin C). Every meal is, literally, a pharmacy of precision.
| Messenger | What it awakens | Precursor & sources |
|---|---|---|
| Dopamine | Drive, motivation, focus | Tyrosine — almonds, raw cacao, squash |
| Serotonin | Stable mood, satiety, serenity | Tryptophan — hemp, dates, banana |
| GABA | Calm, release, sleep | Glutamate + B6 — tea, ferments, buckwheat |
| Acetylcholine | Memory, learning, clarity | Choline — lecithin, soy, seeds |
This is exactly the logic of our Suprême bars: choosing the active ingredient — brahmi, saffron, phycocyanin — that supports one precise neurotransmitter, within a base of raw honey and Criollo cacao that carries its assimilation. Adaptogens (ashwagandha, rhodiola) and plant nootropics do not dope: they help the terrain rediscover its balance.
Hormesis — the right dose of challenge
The body grows stronger from what challenges it a little. This is hormesis: a brief, controlled stress triggers a repair greater than the stress itself. Cold, heat, brief hunger — so many doors our ancestors crossed each day, and that we have closed.
Cold
A cool end to the shower, thirty seconds, awakens circulation, raises noradrenaline and dopamine, and leaves a lasting clarity. The body, taken by surprise, falls into order and wakes.
Heat
The sauna, or a hot bath, dilates the vessels, releases repair proteins and relaxes deeply. Heat then coolness: the contrast is a massage for the nervous system.
Brief hunger
Tightening the eating window — eating within ten to twelve hours, leaving the night for digestive rest — awakens autophagy, that great cellular housekeeping. It is the agni of Ayurveda, confirmed by chronobiology: the fire settles when it is given the time.
The breath — the only conscious lever
Of all the involuntary functions — the heart, digestion, the hormones — only one opens to our will: breathing. It is the handle by which we can take hold of the nervous system. To slow the breath, to lengthen the exhale, is to tell the body, in a few cycles, that it may leave its alert.
“The body is not broken — it is awaiting its signals. To give them back is to watch it bloom again.”

Frequently asked questions
- What is biohacking, really?
- Far from gadgets, the most intelligent biohacking consists in giving the body back the ancestral signals modern life has taken from it: morning light, evening darkness, cold, heat, brief hunger, conscious breath. As Gary Brecka reminds us, the body is not broken, it is depleted: we first fill the foundations (oxygen, light, minerals, water, breath) before any sophisticated protocol. The most powerful hack is a return.
- How do you feed your neurotransmitters through food?
- Neurotransmitters are built from amino acids and cofactors supplied by meals. Tyrosine (almonds, raw cacao, squash) becomes dopamine — drive and focus. Tryptophan (hemp, dates, banana) becomes serotonin then melatonin — mood and sleep. Choline (lecithin, seeds) supports acetylcholine — memory. Adaptogens (ashwagandha, rhodiola) and plant nootropics help the terrain rediscover its balance rather than forcing it.
- Why is morning light so important?
- Morning light received in the eye within the first hour of the day sets the internal clock: it triggers the waking cortisol at the right moment and programs, twelve to fourteen hours later, the melatonin that will open the door to sleep. Ten minutes outdoors on waking, even under a cloudy sky (the outdoors remains ten to a hundred times brighter than a room), without glasses or a window pane, anchor the whole rhythm of the day and of the night to follow.

The Intelligence of the Body
Precise and accurate knowledge
Intelligence is already here, within our body — perhaps the most sophisticated and subtle technology known to us.
- — I —
Energy
the inner flame
We do not eat — we burn stored light. The body is a solar machine running on two fuels.
- — II —
Proteins
the brick of the living — and its hidden origin
Meat does not contain proteins — it only carries them. The source is the plant.
- — III —
Minerals
the body's lattice
The body is a living geological formation — every mineral becomes an enzyme, a bone, a nerve, a thought.
- — IV —
Recipes & Tips
daily practice
Six engineer's gestures — soak, cook low, tune the umami, vary the oils, dose the acid, sweeten with dates — that wake the full intelligence of living matter.
- — V —
Ingredients & Suppliers
the chain of care
The ingredient is already a spiritual decision — tracing back to the hands that harvested is entering a chain of care.
- — VI —
Ayurvedic Intelligence
six tastes, one fire
A science three thousand years old described, without a microscope, what biochemistry rediscovers today — every meal is a complete sensory pharmacology.
- — VII —
Macrobiotic Intelligence
the Qi of food — Japan & China
The cuisines of East Asia do not nourish matter alone: they set energy in motion. Eating becomes an art of balance — yin and yang, the living Ki, deep umami.
