Can someone just tell me what to eat?

Not a tracker. Not a diet.
Just answers your body actually understands.

No email required.

Ever feel off — and have no clue why?

Your body isn't random. It speaks in patterns. Fyll decodes your meals, moods, and cycle — so you can finally understand what it's asking for.

You've tried clean eating.
Tracking. Guessing.
Let's try listening.

There are no wrong answers. Only patterns you haven't seen—yet.

What your body could be trying to tell you

You haven't told us anything yet — but we've seen these patterns in hundreds of women just like you.

"I always got hit with brain fog at 3PM. It wasn't burnout — it was blood sugar."
"Every time I skipped lunch, I ended up bingeing by dinner. Stress hormones mess with hunger more than I knew."
"I was eating 'clean,' but still crashing mid-morning. Turns out, I just wasn't eating enough — or enough protein."

This is where it started.

I did everything right. Fasting. No carbs. Eating clean.💔I still felt like my body hated me.I didn't need more rules. I needed a way to understand what the hell my body was asking for.

Ready to stop guessing and
finally feel good in your body?

Fyll finds the patterns no one else caught.
