A personal project by a French engineer

It was never a willpower problem. It’s a pattern.

Seven Fog Patterns shape how energy, focus, and cravings move through a day after 45. A free three-minute quiz points to yours — and gives it a name.

There are seven. One of them is quietly running your energy, your focus, and your afternoon cravings after 45 — and in 3 minutes, I’ll show you yours.

Why this exists

My mother’s memory is fading.

I watch her forget the recipes she taught me. The waffles we made together on Sunday mornings. The little rituals that built my childhood.

So food and memory are not abstract topics for me. They are my family.

I’m an engineer. When something matters to me, I study it. I spent hundreds of hours reading metabolic research. I wore a glucose monitor and watched my own blood sugar rise and fall on a graph, meal after meal, for months.

I thought knowledge would be enough.

Then one afternoon I walked into a grocery store for blueberries. The bakery had just pulled bread from the oven. And my brain — my careful, educated, data-driven brain — said: eat the bread. Eat it now.

I stood there with all my science, and the smell of warm bread won.

For a while, I was angry at myself. Where was my discipline?

And then, after months of glucose curves, after hundreds of hours of research, after watching my mother lose the very memories that food had built for us — I realized something simple:

It was never a willpower problem. It was a pattern problem.

The craving didn’t start in the bakery. It started hours earlier — in how I slept, when I ate, what my morning looked like, what my day had already taken out of me. By the time I smelled the bread, the decision was already made.

I was fighting single moments. The pattern was running the whole day.

Once I saw my own pattern, I stopped fighting my body and started working with it. Small swaps. Same pleasures. New habits that fit my real life. Nothing extreme, nothing joyless.

That shift is what this project is about.

Christophe with his mother, who is smiling at him — My mother and me. She is the reason this exists.

What you’ll find here

A short quiz. Real questions about your real day — your energy, your sleep, your meals, your evenings. It takes about three minutes.

Your answers point to one of seven common Fog Patterns. You get your pattern, with a name, for free.

Naming it matters. Once a pattern has a name, you are not fighting a vague feeling anymore. You are looking at something you can actually see — and work with.

What this is not: a diagnosis, a treatment plan, or a weight-loss promise. I am not a doctor. This is an orientation — a clear place to start, built on published research and careful pattern work.

“Know your body. Know your patterns. Age with wisdom.”

Who I am

I’m Christophe. French, an engineer, a father, and a son.

For over twenty years I’ve made my living finding patterns in complex systems. When my mother’s memory began to fade, I turned that same way of thinking toward the questions that kept me up at night: why we eat the way we eat, and what it does to our brains over time.

One promise: there is a real person on the other side. If you want to talk through your results, you talk to me.

Give your pattern a name

Three minutes. A few honest questions. A name for something you may have been fighting blind for years.

The art of aging well begins with self-knowledge.
