6 Key Concepts
Insulin Resistance
Insulin is a hormone that escorts glucose into cells for use. When a person is insulin resistant, this system doesn't work properly, meaning glucose and insulin cannot efficiently enter the cells. This leads the body to store them as fat.
Estradiol
Estradiol is the most powerful form of estrogen that is present in a woman's body from puberty. It has receptor sites on every major organ, including the cardiovascular system, gut, brain, and kidneys, activating many bodily processes, including metabolic ones. Its decline, starting around age 40, can lead to issues like increased insulin resistance.
Progesterone
Progesterone is a calming hormone that helps women sleep and manage stress. As progesterone levels decline, typically starting around age 35, women may experience lower quality sleep, increased perceived stress, and higher cortisol levels, contributing to belly fat accumulation.
Evolutionary Mismatch
This term describes how the modern world, with its physical, emotional, and chemical stressors, negatively impacts women's hormonal health. While women might 'get away with' certain lifestyle choices in their 20s and 30s, these become detrimental in perimenopausal years due to hormonal changes.
HPA Axis Dysfunction
The Hypothalamus-Pituitary-Adrenal (HPA) axis is the body's master control center for hormones and stress response. Chronic, unmanaged stress can lead to dysfunction in this axis, often referred to as 'adrenal fatigue,' impacting overall hormonal balance and well-being.
Thrifty Gene Hypothesis
This hypothesis suggests that humans evolved with a specific genetic profile allowing them to endure long periods without food. In the modern world, constant eating goes against this genetic profile and is believed to contribute to conditions like diabetes.
7 Questions Answered
Weight gain is not inevitable for women as they age, but it can be if they don't understand how to harness their hormones. Declining estrogen levels can lead to insulin resistance, and reduced progesterone can increase stress and cortisol, both contributing to weight gain if lifestyle isn't adjusted.
Women often struggle with sleep in their 40s because progesterone, the calming hormone that aids restful sleep, declines during perimenopause. This hormonal shift makes it harder to fall asleep and stay asleep, regardless of effort.
During the first 10 days (Power Phase), women can push hard with cardio and intense workouts. Days 11-15 (Manifestation Phase), when testosterone peaks, are ideal for heavy weightlifting to build muscle. The final week before a period (Nurture Phase) should focus on recovery, with lighter workouts like yoga or walking.
Understanding the cycle allows partners to adapt communication and support. Days 11-15 (Manifestation Phase) are best for resolving conflict due to balanced hormones. The week before a period (Nurture Phase) requires more space and support, as women may be more introverted and irritable due to hormonal shifts, which should not be taken personally.
Fasting is a healing state, but not everyone thrives in a fasted window immediately. It should be approached cautiously with eating disorders, and is not recommended during pregnancy or for nursing mothers (beyond 15 hours). For those with chronic stress or adrenal fatigue, a 'tiptoeing in' approach to gradually extend fasting windows is recommended.
For postmenopausal women, exercise becomes crucial for brain health, as the loss of estradiol and progesterone impacts neurochemicals like dopamine, serotonin, and oxytocin. Varied exercise, including pushing workouts and heavy weights, can stimulate BDNF and support neuronal growth and neuroplasticity.
The gut contains specific bacteria that break down estrogen. If this microbiome is imbalanced or the liver is overloaded, estrogen may not be properly eliminated and can be stored as fat, contributing to weight gain and potentially increasing cancer risk. Supporting gut diversity with polyphenol, probiotic, and prebiotic foods is crucial.
25 Actionable Insights
1. Look Through Hormonal Lens
For women over 40, shift your approach to weight loss from grit and discipline to a hormonal lens, as declining estrogen causes insulin resistance and declining progesterone increases cortisol and belly fat, making traditional methods ineffective.
2. Honor Pre-Period Rest
Prioritize rest and recovery in the week before your period by slowing down workouts, increasing nature’s carbs, prioritizing sleep, and reducing stress, to support progesterone and prevent cycle issues.
3. Tailor Exercise to Cycle
Adopt a monthly exercise schedule: push hard with cardio/HIIT in the first 10 days, prioritize heavy weightlifting during ovulation (days 11-15), and engage in gentle exercise in the nurture phase (week before period) to maximize benefits.
4. Integrate Lifestyle with HRT
Even if using HRT or bioidenticals, consistently implement lifestyle changes like fasting, varied diet, microbiome support, toxicity reduction, and self-care, as they are crucial for optimal health and symptom management.
5. Fast Regularly (Cycle Sync)
Incorporate varied fasting lengths into your routine to improve insulin sensitivity and manage menopausal weight gain, ensuring to reduce fasting intensity or duration in the week before your period.
6. Reduce Toxic Exposure
Minimize exposure to toxic beauty products, perfumes, air fresheners, and household cleaners, as these can disrupt hormonal control centers in the brain and negatively impact hormonal health.
7. Support Your Microbiome
Consume polyphenol, probiotic, and prebiotic-rich foods (e.g., sauerkraut, diverse vegetables) to support gut bacteria essential for breaking down estrogen, preventing its accumulation.
8. Prioritize Self-Care Nurture
Actively seek out self-care activities, learn to say no more often, and reduce people-pleasing tendencies to nurture yourself, particularly in the week before your period, to mitigate stress and support hormonal well-being.
9. Time Dinner for Sleep
Avoid eating dinner in the dark when melatonin rises and insulin resistance increases, and ensure you are not going to bed while actively digesting food, as both can hinder restful sleep.
10. Reset Circadian Rhythm
Get up close to sunrise to see red light, which turns off melatonin and starts the circadian rhythm, and get midday sun exposure without sunglasses, to improve insulin sensitivity and sleep quality.
11. Move After Morning Cortisol
About an hour after seeing morning light, engage in physical activity like walking or working out to utilize the natural cortisol surge, preventing its storage and contribution to belly fat.
12. Optimize Sleep Environment
For women over 40, keep your sleeping environment cold and consider using a weighted blanket to help activate the parasympathetic nervous system, promoting calmness and counteracting heat signals from declining estrogen.
13. Adapt Winter Meals
In winter, when daylight hours are shorter, consider making your heaviest meal at midday and a lighter meal later, and incorporate a walk or air squats after your biggest meal to manage glucose.
14. Reframe PMS Symptoms
Understand that intense PMS symptoms (cravings, fatigue, irritability) are often signals that your lifestyle is working against your biology, empowering you to make supportive changes rather than feeling like a personal failing.
15. Communicate Cycle to Partner
Share your menstrual cycle phase with your partner, especially your ’nurture phase’ (week before period), to foster mutual understanding, support, and improve relationship harmony.
16. Resolve Conflict During Ovulation
Address deep conflicts or important discussions with a woman during her manifestation phase (days 11-15) when she has optimal hormonal balance for connection, verbal processing, and calmness.
17. Exercise for Brain Health
For post-menopausal women, prioritize exercise specifically for brain health to counteract the loss of neurochemical-stimulating hormones, and consider a varied weekly or simulated 30-day cycle plan.
18. Avoid Alcohol (Ovulation/Post-Ovulation)
Minimize alcohol intake around ovulation and in the post-ovulation phase to reduce additional strain on the liver, which is critical for efficiently breaking down and eliminating hormones.
19. Tiptoe into Fasting (Stress/Fatigue)
If experiencing chronic stress or adrenal fatigue, gradually increase your fasting window by small increments to allow your body to adapt and heal, rather than initiating long fasts abruptly.
20. Break Fasts with Protein
When breaking a fast, ensure your first meal contains at least 30 grams of protein to effectively stimulate muscle building and support overall recovery and metabolic health.
21. Protein Cycle for Athletes
Female athletes can optimize performance and muscle building by alternating between periods of longer fasting (Monday-Thursday with protein-rich meals) and non-fasting days with high protein intake (Friday, Sunday).
22. Observe Fasting Contraindications
Do not fast if pregnant, nursing (limit to 15 hours), or if you have an eating disorder, as these are critical contraindications requiring professional guidance or complete avoidance.
23. Fasting for Infertility
For women trying to conceive, implement a fasting cycle: more fasting in the first half to optimize estrogen, reduced fasting with nutrient-dense foods around ovulation, and hormone feasting post-ovulation.
24. Curiosity in Health Choices
Approach health changes with an open mind and curiosity, trying different strategies to discover what works best for your unique body, rather than seeking absolute, one-size-fits-all answers.
25. Journal During Fasting
Utilize a journal during fasting to record thoughts and feelings, which can help identify limiting beliefs or emotional responses to hunger, potentially leading to personal growth and a healthier relationship with food.
6 Key Quotes
The minute you flip the whole discussion on its head, the minute you start to look at it through a hormonal lens. And now that woman can start to get some serious weight loss results when she comes at it from hormones, not from grit and discipline.

We have estradiol going down, making you more insulin resistant. And we have progesterone going down, destroying your ability to handle stress, making cortisol go up. And there you go. Now you've got menopausal belly weight because cortisol is up and you're insulin resistant.
Dr. Mindy Pelz
The beauty of being a woman is that there is nothing simple about your body.
Dr. Mindy Pelz
The new version of women empowerment is that we take a moment that week before to just honor the fact that our body needs to recover so we can come back out on day one and we can go at it again.
Dr. Mindy Pelz
When a woman is ill, she doesn't think that it's the problem with the food system. She doesn't think that it's her work environment. She thinks she did something wrong. She thinks she's not disciplined enough.
Dr. Mindy Pelz
If the way we have done it is, is working, which I'm going to call the way we have done it is you have a set of symptoms, you're given a specific diagnosis, you're given a tool like a medication or a surgery. If that was working, why are we as culturally as a world sicker, more obese, more chronic disease than ever before?

5 Protocols
Sleep Hacks for Perimenopausal and Menopausal Women
Dr. Mindy Pelz- Get up close to sunrise to see red light, which turns off melatonin and starts the circadian rhythm, bringing the body into a more insulin-sensitive state.
- About an hour after waking, when cortisol kicks in, move your body through walking or working out to use the cortisol.
- Go out in the sun midday without sunglasses to let eye receptors see daytime light.
- At night, observe the sunset to help train the circadian rhythm.
- Time dinner carefully: avoid eating dinner in the dark when melatonin is high, as this increases insulin resistance.
- Ensure dinner is eaten early enough so the body is not digesting food when going to bed, to improve sleep quality.
- Keep the room cold, as declining estrogen can signal the brain to turn up heat.
- Use weighted blankets to help activate the parasympathetic nervous system, promoting a calmer state for sleep.
Exercise Protocol for the Menstrual Cycle
Dr. Mindy Pelz- Days 1-10 (Power Phase): Push hard with workouts, including cardio and high-intensity interval training (HIIT). If lifting weights, aim for higher reps (e.g., 15 reps instead of 10) to maximize effort.
- Days 11-15 (Manifestation Phase/Ovulation): Focus on heavy weightlifting to build muscle, utilizing the surge of testosterone. Examples include dedicated days for biceps/triceps, legs/glutes, or chest/back.
- Days 16-19 (Second Power Phase): Continue with moderate to intense workouts, similar to the first power phase, as hormone levels are still supportive.
- Days 20-28 (Nurture Phase/Week Before Period): Prioritize recovery and lighter activities. Reduce workout intensity, opting for yoga, walking, or gentler forms of exercise. If following a regular gym routine, modify the intensity rather than stopping completely.
Five Lifestyle Changes for Women Over 40
Dr. Mindy Pelz- Vary your fasts: Implement fasting, but vary the lengths. For perimenopausal women, this means adapting fasting to their cycle (e.g., a 15-hour fast for 3 weeks, then no fasting the week before their period). For postmenopausal women, create a monthly or weekly rhythm for fasting.
- Vary your foods: Incorporate a diverse range of foods, aiming for at least 200 different foods in a month, to support the gut microbiome. Include nature's carbs (fruits, vegetables, potatoes) and prioritize them the week before a period or in designated 'high carb' weeks for postmenopausal women.
- Support your microbiome: Focus on polyphenol, probiotic, and prebiotic-rich foods (e.g., sauerkraut, diverse vegetables) to aid in estrogen breakdown and elimination. Avoid alcohol around ovulation and post-ovulation to support liver function.
- Reduce toxicity: Minimize exposure to toxic products (e.g., lotions, perfumes, household cleaners) that can disrupt hormonal control centers in the brain (hypothalamus, pituitary, pineal gland). Use apps like Skin Deep or Think Dirty to identify safer products.
- Prioritize self-care and nurture: Actively seek out ways to nurture yourself and reduce stress. This includes learning to say 'no' more, pleasing people less, and incorporating activities like massages, nature walks, or quiet time, especially during the nurture phase of the cycle.
Fasting and Eating Protocol for Female Athletes
Dr. Mindy Pelz- Monday-Thursday: Eat a lot of protein during eating windows and experiment with longer fasts (e.g., 15-hour, 24-hour, 17-hour fasts). Work out in a fasted state. Ensure the first meal after a fast contains 30 grams of protein.
- Friday (Protein Cycling Day): Do not fast. Consume 20-30 grams of protein every two hours throughout the day to stimulate mTOR and build muscle.
- Saturday (Competition/Hardest Workout Day): Do not fast. Consume carbohydrates before the workout if preferred, and ensure adequate fueling for demanding physical activity.
- Sunday (Protein Cycling Day): Do not fast. Repeat the protein cycling protocol from Friday, consuming 20-30 grams of protein every two hours.
Fasting Protocol for Shift Workers (e.g., 8 PM - 8 AM shift)
Dr. Mindy Pelz- Eat a substantial dinner (e.g., high protein, healthy fats, complex carbs like sweet potato) before starting the shift (e.g., 7:30 PM).
- Fast throughout the entire night shift, avoiding food intake.
- Stay hydrated during the shift with mineral water, plain water, or unsweetened tea/coffee (no sugar or artificial sweeteners).
- Upon returning home in the morning, eat a light meal.
- Prioritize sleep and recovery during off-shift hours.
