Frequently Asked Questions
Why does fasting need to be different for women?
Women's bodies are governed by a delicate rhythm of estrogen, progesterone, and LH. Constant, long-duration fasting can signal starvation to the brain, disrupting hormone production and leading to symptoms like irregular cycles or hair loss. FastingLady helps you adjust your fasting window according to your cycle phase.
Is FastingLady based on 'Fast Like a Girl'?
Yes! FastingLady is heavily inspired by the cycle-syncing principles in Dr. Mindy Pelz's book, 'Fast Like a Girl'. It simplifies the process by categorizing your cycle days into Power 1, Manifestation, Power 2, and Nurturing, advising you on the ideal fasting lengths for each.
Do I have to log my food or calories?
No. FastingLady believes in building a healthy relationship with your body. We focus entirely on fasting schedules and cycle synchronization, keeping the app free of calorie counting and food logs.
Can I use FastingLady if my cycles are irregular?
Yes. You can manually adjust your cycle length or log the start of your period at any time, and the app will recalculate your cycle days and recommend fasting protocols accordingly.
Is there a free trial?
FastingLady is free to download and offers a fully functional fasting timer. Premium features, including full cycle-syncing insights, personalized recommendations, and the companion Apple Watch app, are available via subscription.
