Fasting, Hormones & Menopause: Why Women Need A Different Approach To Men with Dr Mindy Pelz #342

Mar 8, 2023 2h 4m 32 insights
CAUTION: This podcast discusses fasting, and its advice may not be suitable for anyone with an eating disorder. If you have an existing health condition or are taking medication, always consult your healthcare practitioner before going for prolonged periods without eating. Today’s podcast could transform the lives of many women – but it’s a conversation that is just as relevant for men. My guest is Dr Mindy Pelz, a nutrition expert, an author and a pioneer on the subject of women’s health, hormones and fasting. Fasting itself is a topic we’ve spoken about before on this podcast, but when we talk about fasting and health in general, we often presume that men and women are going to respond in the same way. As Mindy explains, men and women are fundamentally different biologically and hormonally, which means they may need to adopt different approaches. Mindy’s new book Fast Like A Girl explains that distinction and goes on to provide the protocols women can use, so fasting works in their favour. It’s billed as a women’s guide to using fasting to burn fat, boost energy and balance hormones. But I’d argue that it gives us a whole lot more than that. Mindy sets out the key hormonal differences between men and women. With men governed primarily by testosterone, released at regular intervals and doses throughout the day. Women are led by a symphony of oestrogen, testosterone and progesterone in amounts that vary across an average 28-day menstrual cycle.   Mindy talks us through what exactly is going on hormonally during the four phases of a woman’s cycle and how this makes women feel physically, cognitively and emotionally. She explains how women can tailor everything from their working habits to their workouts, their social life to their diet, to better match their hormone profile at each stage of the cycle - this approach can help women feel more in control. We discuss the benefits for conditions like polycystic ovarian syndrome (PCOS), infertility and irregular cycles. We also discuss the different stages of women’s lives – reproductive, perimenopausal and post-menopausal – and how different types and lengths of fasting can be optimised in each stage. This is not just an empowering listen for women, it is for all of us – partners, brothers, fathers, sons, and friends. I hope you enjoy listening. Support the podcast and enjoy Ad-Free episodes.

Actionable Insights

1. Honor Women’s Biological Differences

Stop trying to do everything (eating, working out, medications) the same way as men, as women are massively different biologically and hormonally and need tailored approaches to thrive.

2. Cycle-Sync Your Lifestyle

Tailor everything from working habits, workouts, social life, and diet to better match your hormonal profile at each stage of your menstrual cycle to feel more in control and improve conditions like PCOS, infertility, and irregular cycles.

3. Learn Cycle Hormonal Fluctuations

Understand the four phases of the menstrual cycle (Power, Manifestation, Second Power, Nurture) and how hormones (estrogen, progesterone, testosterone) vary, as this foundational knowledge empowers women to work with their bodies.

4. View Fasting: Therapeutic Healing State

Stop viewing fasting as a fad diet and instead see it as a therapeutic healing state that builds health and prevents disease, as the human body was designed to have periods without food.

5. Heal Metabolic Dysfunction

If you struggle to go without food for even 8 hours, recognize this as a warning sign of mitochondrial dysfunction or early diabetes. Use a ‘pre-reset’ (e.g., two weeks of cleaning up food) to slowly train your body to fast, as it gets easier with practice.

6. Fasting for Perimenopause

Women over 40 (perimenopausal) should use fasting as an imperative tool to keep age-appropriate estrogen levels high and become more insulin sensitive, as estrogen decline makes them more insulin resistant and can lead to weight gain and cognitive issues.

7. Post-Menopausal 5-1-1 Fasting Protocol

Post-menopausal women should follow a weekly fasting pattern like the 5-1-1 protocol: five days of a favorite fast (e.g., 15-16 hours) with a low-carb/ketobiotic diet, one day of a longer fast (e.g., 24 hours for gut repair), and one day of no fasting with hormone-feasting foods to support progesterone and improve sleep/anxiety.

8. Fasting for Fertility and PCOS

Women in their fertility years (e.g., with PCOS or struggling to get pregnant) should use fasting to become insulin sensitive and allow estrogen to function properly, potentially restoring regular cycles and improving fertility.

9. Power Phase Longer Fasts

During the first 10 days of the menstrual cycle (Power Phase, starting with the first day of the period), when hormones are low and women are insulin sensitive, they can tolerate longer fasts (e.g., 24-hour, 36-hour, 48-hour, 72-hour fasts) and a low-carb diet.

10. Power Phase Intense Workouts

During the first 10 days of the menstrual cycle (Power Phase), women can push hard with workouts, including HIIT training and plyometrics, as their hormones can handle it.

11. Manifestation Phase Shorter Fasts

During the ovulation phase (Manifestation Phase, roughly day 10-15), when estrogen and testosterone are at their peak, women should keep fasts under 15-16 hours to avoid excessive detox reactions due to hormone metabolism.

12. Manifestation Phase Liver Support

During the ovulation phase, focus on metabolizing hormones by supporting the liver and gut with bitter foods (radicchio, lemons, ginger, arugula) and avoiding alcohol. Increase polyphenol, probiotic, and prebiotic foods (fermented foods, nuts, seeds, green leafy vegetables) to support the estrobilome in breaking down estrogen.

13. Manifestation Phase Lift Weights

During the ovulation phase, leverage high testosterone levels to build muscle by doing heavier weightlifting workouts.

14. Second Power Phase Longer Fasts

After ovulation (roughly day 16-19), when hormones are low again, women can reintroduce longer fasts (e.g., 24-hour, 48-hour) and a low-carb style of eating.

15. Second Power Phase Push Activities

During the second power phase, women can push their workouts and ramp up their social calendar and workload due to low hormone levels.

16. Nurture Phase Minimize Fasting

The week before a woman’s period (Nurture Phase, roughly day 20-28), when progesterone needs glucose to be higher and the body is more insulin resistant, women should minimize or avoid fasting (keep under 13 hours if metabolically flexible) to prevent raising cortisol, which can hinder progesterone production.

17. Nurture Phase Feast Carbs

During the week before a woman’s period, lean into ‘hormone feasting foods’ like smart carbs (potatoes, sweet potatoes, squashes, quinoa, citrus/tropical fruits) and clean chocolate (for magnesium) to support progesterone production and manage cravings.

18. Nurture Phase Reduce Stress

During the week before a woman’s period, women should slow down, reduce stress, say no to more things, and focus on self-care. Exercise should be softer (e.g., yoga, Pilates, walking, hiking) to allow the female body to recover.

19. Reset Irregular Cycles

If you have an irregular or absent cycle, follow a 30-day fasting reset protocol (day 1-30, repeated for 30-90 days) to help balance hormones and bring your cycle back into sync, potentially improving fertility.

20. Plan Life by Cycle

Women with regular cycles can plan their work, social, and exercise calendars according to their menstrual phases, leveraging power phases for high-stress activities and nurture phases for recovery.

21. Mindful Communication with Women

Men (partners, fathers, sons, friends) should understand women’s hormonal flux and adapt communication, such as avoiding tough conversations the week before a woman’s period and choosing times when hormones make them more verbally outward.

22. Intermittent Fasting (12-16 Hours)

Aim for 12-16 hour fasts to switch into the fat-burning system, produce ketones (which calm and reduce hunger), lower inflammation, and boost growth hormone.

23. Autophagy Fast (17+ Hours)

Engage in 17+ hour fasts to trigger autophagy, where the body repairs cells, removes damaged components (bacteria, viruses, senescent cells), and initiates apoptosis to eliminate rogue cells.

24. Gut Health Fast (24 Hours)

Perform 24-hour fasts to reboot intestinal stem cells, repair the gut lining (beneficial for leaky gut, SIBO), eliminate bad bacteria, and redistribute microbes for better nutrient absorption.

25. Fat Burner Reset (36 Hours)

Utilize 36-hour fasts (e.g., alternating with 12-hour eating windows) to lose more weight, particularly visceral belly fat, and convert white fat into more easily burnable brown fat.

26. Dopamine Reset Fast (48 Hours)

Engage in 48-hour fasts to reset the entire dopamine system, increase dopamine receptor sites, and enhance enjoyment of simple life pleasures, which can help overcome food addiction.

27. Immune Reset Fast (72 Hours)

Implement 72-hour fasts to reboot the entire white blood cell and immune system.

28. Embrace Micro Discomfort

Actively seek small doses of discomfort, like extending fasts, as these hormetic stressors strengthen the body and mind, revealing new coping mechanisms and dopamine-stimulating activities.

29. Gradually Train for Fasting

Approach fasting as a training process, starting with shorter fasts and gradually increasing duration. Be playful and curious, understanding that initial difficulty is part of adaptation, and it gets easier over time.

30. Fasting Caution: Eating Disorders

If you have an eating disorder or are recovering, involve your therapist and doctor in any fasting experience, or avoid fasting, to prevent triggering harmful patterns.

31. Fasting Caution: Pregnancy

Pregnant women should not use fasting as a tool; instead, focus on other health aspects like the microbiome.

32. Fasting Caution: Nursing

Nursing women should keep fasts under 15 hours to avoid stimulating autophagy and potentially pushing toxins into breast milk.
