WHAT IT’S REALLY ABOUT

Intermittent Fasting That Actually Works For Women’s Hormones And Health

  1. Mel Robbins and Dr. Mindy Pelz unpack how to implement intermittent fasting as a practical, step‑by‑step health protocol that focuses on when you eat, not what you eat. They explain the basic science of switching between sugar-burning and fat-burning states and outline what to expect physically and mentally when you first start fasting. A major focus is why women must fast differently than men due to monthly hormonal rhythms, especially the distinct needs of estrogen and progesterone, and how to adapt fasting around menstrual cycles or the moon. The episode ends with simple hacks, food guidelines, and a four-step framework for building a sustainable, community-supported fasting lifestyle.

IDEAS WORTH REMEMBERING

5 ideas

Treat fasting as a timing protocol, not a restrictive diet.

Intermittent fasting is about creating clear windows of eating and not eating (e.g., 12–16 hours without food) so your body can shift into fat-burning and cellular repair, independent of specific calorie counting or food rules.

Expect short‑term discomfort as your body transitions into fat burning.

Headaches, moodiness, brain fog, digestive changes, or mild detox symptoms can appear in the first 1–3 days; these usually pass as your metabolism adapts, similar to the temporary pain of a sprained ankle healing.

Women must adjust fasting around hormonal rhythms, especially progesterone.

Estrogen generally thrives with fasting, but progesterone (dominant the week before a period) needs higher glucose and lower stress; fasting hard all month can tank progesterone, leading to anxiety, hair loss, missing periods, and weight gain.

Cycling women should avoid fasting the week before their period.

Dr. Pelz’s simplest rule: fast as you like the rest of the month, but the week before your period, stop fasting and intentionally increase “nature’s carbs” (fruit, potatoes, whole-food starches, dark chocolate) to support progesterone.

If you don’t have a regular cycle, anchor fasting to the moon.

For women on hormonal birth control, in perimenopause, or postmenopause, use the lunar cycle: start about 21 days of intermittent fasting on the new moon, then take roughly 7 days off fasting around the full‑moon time to mimic natural hormonal rhythms.

WORDS WORTH SAVING

5 quotes

Fasting is a protocol that focuses on when you're eating for maximum health benefit.

— Mel Robbins

Women follow what I call a hormonal hierarchy… and when oxytocin goes up, it brings cortisol down, makes you more insulin sensitive, and then your sex hormones balance.

— Dr. Mindy Pelz

Don't fast the week before your period if you're a cycling woman.

— Dr. Mindy Pelz

We craved carbs before our period not because we were undisciplined, but because progesterone was asking you to bring your glucose up.

— Dr. Mindy Pelz

This is a zero-cost tool that helps you unlock the extraordinary power of your body to heal itself.
