I'm Josef, the technical co-founder of Bauchgefühl. I built the app. My background is engineering, not medicine, not nutrition. That matters, so I'm saying it up front.
Now the obvious question. I'm a guy. I don't have a cycle. Why am I building an app about cycle-based nutrition?
Because Marie kept telling me how much eating the right thing at the right time changed her week. First I listened. Then I started reading the studies she forwarded me. And as an engineer I got a bit obsessed with whether you could package that into something that doesn't feel like yet another tracker designed to make you feel guilty. Something that tells you on a Tuesday morning what you could actually cook, without having to read three articles first.
I don't have medical credentials and I'm not going to invent any. What I can do is build software that holds up in real life and write honestly about what I've learned while building it. Everything published here under my byline belongs to that second category: engineering notes, researched basics, peer read by Marie.
If you spot something that's wrong, tell us. We'll fix it and leave a note at the bottom of the article.
