The cycle-synced
fasting guide

Most fasting advice was written as if women had the same 24-hour hormone cycle as men. They don't. These guides walk through what actually works, phase by phase — so you can fast in a way that feels good instead of fighting your body.

Start here: foundations

The broad, practical guides that explain the full model and show how fasting for women works when it actually follows female physiology.

Work with your cycle: by phase

Phase-by-phase playbooks for the days when your body needs a different fasting window, different meals, and a different level of intensity.

Cycle phase

Menstrual phase (days 1–5)

Fasting guidance for the days of your period: gentler windows, restoration-focused food.

When things are different

Supportive guides for women whose hormones, timing, or life stage do not fit a neat phase-calendar pattern.
