Description
Stop fasting like a man. Your body has a rhythm - it’s time to learn how to fast like a woman.
Most health advice is based on studies done on men, whose hormones reset every 24 hours. But women’s hormones shift across a 28-day cycle, affecting energy, metabolism, and nutritional needs week by week.
Fasting Bestie is the fasting timer designed to sync your intermittent fasting windows with your unique 28-day cycle. So you can burn fat, boost energy, and support your hormones without stress.
WHY GENERIC FASTING APPS FAIL WOMEN
Most apps push the same 16:8 routine every day. Fasting aggressively during your Luteal phase (the week before your period) can increase cortisol, disrupt progesterone, and lead to burnout.
Fasting Bestie helps you adapt your fasting window to work with your hormones automatically.
SYNC WITH APPLE HEALTH
