Mitochondria Life

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

Why do you breathe?
And why does stopping kill you?

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.

Every one of them was for your mitochondria.

Nothing is closer to life itself. And we barely know them.

Your body is
not yours alone

~10%

of your body weight is mitochondria. At 60 kg, that's about 6 kg.

4070 kg

of ATP made every day. About your body weight, and it never pauses. The meter above is a sliver of it.

STORY

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.

Losing weight is what happens
when the power plant gets healthy

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.

A shift in thinking

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.

Proven by peer-reviewed science

Weight loss

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.

Less fatigue, fewer falls

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).

Healthy longevity

Keeping them healthy is the foundation of a long, active life.

-35%

People with higher physical activity have about 35% lower all-cause mortality (meta-analysis of 80 cohorts, 1.33 million people).

Sources: peer-reviewed papers (meta-analyses and others). Results vary between individuals.

Don't make them read the book.
Put it in the body, through play.

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.

Science and story, one to one

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.
