Episode 237: Does Fasting Affect Your Menstrual Cycle? The Truth About Intermittent Fasting and Your Period
If you’ve ever wondered whether fasting is actually helping your hormones or secretly wrecking them, this episode is for you. Most fasting studies are done on men or postmenopausal women, which means if you’re cycling, you’re playing by a completely different hormonal rulebook.
In this episode I’m sharing:
Why fasting impacts women’s hormones differently than men’s (and how stress, cortisol, and progesterone all tie in)
The hidden ways fasting can lower your LH, disrupt ovulation, and tank your progesterone levels
Symptoms that your fasting routine is backfiring, such as irritability, insomnia, thinning hair, and irregular cycles
Why extreme fasting is often just a “fancy way of not eating enough” and how that triggers fight-or-flight mode
How to know if your minerals, adrenals, or calorie intake make fasting unsafe for your body right now
Circadian fasting and how to do it properly for hormone support
Why it matters when you eat, not just what you eat, and how nighttime insulin resistance affects fat storage and sleep
How to break your fast correctly to protect your blood sugar and adrenals
My favorite way to adapt fasting to your cycle using short “follicular fasts” without stressing your hormones
Remember: fasting isn’t magic and it’s not evil either. It’s about using it with context, wisdom, and nourishment. This episode will help you understand when fasting helps, when it hurts, and how to align it with your body’s natural rhythm so you can finally feel balanced, energized, and in sync again.
