ミトコンドリア・ライフ — a health companion
It looks like a diet app.
It's built to make humans healthy.
Companion app to the book “Mitochondria Life” / Akiplex
Hold your breath and you die within minutes. Everyone knows that. Almost no one can say why. The answer is mitochondria —— the oxygen you inhale reacts with nutrients inside the mitochondria of your cells and becomes ATP, the energy of life. The moment it runs out, your heart and your brain stop.
Since you opened this page, you have taken 0 breaths.
Every one of them was for your mitochondria.
Based on a resting rate of about 15 breaths per minute
Nothing is closer to life itself. And we barely know them.
of your body weight is mitochondria. At 60 kg, that's about 6 kg.
■ = 1% of your bodyof ATP made every day. About your body weight, and it never pauses. The meter above is a sliver of it.
Mitochondria used to be a separate organism. Around 1.5 to 2 billion years ago, a cell took in a bacterium that could make energy from oxygen and, instead of digesting it, started living with it —— and that arrangement is still running inside you. They still carry their own DNA, separate from the nucleus.
Make a good home for them. That, quite literally, is your health.
Burning fat is not a metaphor. It is the chemical reaction of fat meeting oxygen inside your mitochondria. The more furnaces you have, and the better they run, the more fat burns. So a life that grows mitochondria is, by itself, a diet.
Losing weight is the goal.
Take weight loss off the goal line. The aim is to keep being a better you.
No finish line, so no rebound.
More, and more active, mitochondria make a body that burns fat more easily.
Fat burns as a chemical reaction inside mitochondria. That exercise lowers HbA1c in type 2 diabetes is established by meta-analyses of 100–158 RCTs.
Keep exercising and mitochondria multiply, so the same effort tires you less.
That exercise increases mitochondria (via PGC-1α) is established by meta-analysis (Hedges' g = 1.17).
Keeping them healthy is the foundation of a long, active life.

Sources: peer-reviewed papers (meta-analyses and others). Results vary between individuals.
Raise Mito, a creature that is your mitochondria, through everyday life. Move, and Mito multiplies. Eat well, and Mito is delighted. Eat sugar, and Mito frowns. While you play, you quietly become fluent in mitochondria, and quietly lose weight.
Exercise → more mitochondria → Mito divides
Food, sleep, light → better quality → Mito's look and energy change
Worldview —— Seika, “the quiet fire”. No rushing, no guilt. A warm UX.
