What would you most like to change?
How does your cycle usually run?
Pick the closest.
Where are you in your cycle today?
Not sure is fine.
Have you fasted before?
Either way is fine.
How often do you move right now?
Honestly, not aspirationally.
Anything we should plan your food around?
Any that apply, or skip.

Reading your cycle pattern
Mapping your phase to today
Writing your first day
Here's your first day, built for a regular cycle
You're in your follicular phase, and you told us the scale won't move even when you do everything right. This week your insulin sensitivity is highest, so the plan leans on it: your longest fast and your higher-carb days land now, while they count. Next week the plan changes, because your body will.
