Head Strong
Personal notes, not medical advice.
If mitochondria cannot make enough energy, that is a brownout — and the brain fatigues. The body cannot store this kind of energy for more than a few seconds. It has to be the right kind, in the right amount, just in time.
Evolution wired mind and body around three drives: fear, feed, fuck. The reptile brain runs the electrical system and body temperature; every creature with a spine has one. The labrador brain (mammal) wants to bark, eat, and mount. It means well. Those urges still burn a massive amount of energy. Every decision costs energy. Turn the labrador down and the rest of the brain works more efficiently.
Four points for a stronger, more resilient brain. One: stop sensing energy emergencies. Stop doing what makes the brain weak. Identify personal kryptonite. Two: add more energy. Mitochondria need oxygen, glucose, carbs, and sometimes amino acids — and the ability to alternate sources. Three: raise production and efficiency. Stress, lack of sleep, and toxins work against this. Four: strengthen the mitochondria. Exactly the right amount.
Five weaknesses to watch. BDNF (brain-derived neurotrophic factor) builds neurons. Exercise, diet, and careful supplements can raise it — memory, learning, myelin, neurogenesis. If names, bills, and trains of thought slip, or a pot gets left on the stove, look at mitochondrial function, oxygen delivery, myelination, and food. I score this 3/5.
Biological cravings. Too much sugar and the brain runs on glucose instead of fat; the rest is stored. Glucose burns fast, then a crash, then the labrador shouts for sugar now. Kidney and liver, cleaning toxins, also grab extra glucose and compete with the brain. Noise, bad lighting, stale air make the brain spend energy on filtering. More mitochondria, fewer cravings. Ketosis is the body burning fat for energy. I score this 5/5.
Inability to focus. Repeated fight-or-flight spends emergency energy and cortisol. Over time, insulin resistance: blood cannot use glucose, energy becomes unstable, distraction wins. Stable blood sugar keeps the labrador calm. If conversation jumps, deadlines slip, and thoughts wander — ketosis, breathing, meditation. I score this 1/5.
Low energy is often poor blood-sugar regulation. The brain is served after the body. Muscle weakness, exhaustion after mental or physical work: the right fats, ketosis, and fewer mitochondrial toxins. I score this 4/5.
Moodiness and anger are low brain energy. The prefrontal cortex is dense with mitochondria, needs a massive amount of energy, and gets it last — so it suffers first. It runs mood, personality, decisions, social behavior. Fog, slumps, a short fuse, impulsive calls: dig into toxins and kryptonite. I score this 2/5.
Do right now. Stop blaming yourself for running out of willpower. Cut stimuli when you need to focus — phone, mail alerts. Make the most important decisions first, before brain fatigue arrives.
