Key Takeaways

  • Luteal phase metabolism: In the second half of the menstrual cycle, resting metabolic rate rises by up to 300 calories per day as progesterone peaks and insulin sensitivity drops. Rather than resisting hunger, prioritize balanced meals pairing fiber-rich carbohydrates with protein and fat to stabilize glucose, reduce cravings, and manage PMS mood symptoms.
  • PMS nutrient targets: Calcium, vitamin D, and magnesium deficiencies are linked to worsening premenstrual and PMDD symptoms. Correcting these through diet or supplementation can reduce symptom severity. PMS and PMDD are cyclical disorders — symptoms appear in the luteal phase and resolve at menstruation — distinguishing them clinically from generalized anxiety or depression diagnoses.
  • Menopause bone and cardiovascular protocol: Estrogen decline at menopause sharply raises cardiovascular disease risk and accelerates bone loss. Prioritize calcium, vitamin D, vitamin K, magnesium, and consistent protein across three meals daily. Add weight-bearing and impact exercise at minimum twice weekly. Monitor cholesterol, blood pressure, and fasting glucose via annual blood work starting in your forties.
  • Supplement audit framework: Start one new supplement at a time, run it for eight weeks, then assess whether symptoms improved. Vitamin D is the one near-universal supplement warranted, especially October through March in northern latitudes. Electrolytes are only necessary for endurance athletes or high-heat training sessions — daily use by recreational exercisers risks excess sodium intake and gradual kidney strain.
  • Doctor visit preparation: Bring a symptom diary and wearable trend data — declining HRV, rising resting heart rate, disrupted sleep — to medical appointments to make vague symptoms concrete and trackable. Explicitly request blood work for iron, vitamin D, and other biomarkers. If dismissed, pursue private lab testing, then consult a registered nutritionist to address suboptimal levels before they become clinical deficiencies.

What It Covers

Dr. Hazel Wallace, a medical doctor and registered nutritionist, explains how women's nutritional needs shift across hormonal milestones — menstrual cycle phases, perimenopause, menopause, and postpartum — and why standard dietary guidelines based on male research fail to account for these distinct, changing requirements.

Notable Moment

Dr. Wallace, a practicing medical doctor, received a PCOS diagnosis after two years of being dismissed — then was told by a gynecologist to simply avoid carbohydrates with no evidence basis. She notes this type of throwaway dietary advice from clinicians causes lasting nutritional harm and fear in patients.

Episode Transcript

Nutrition plays a huge role across the lifespan. I studied medicine. I was really excited to learn about nutrition and lifestyle, but you don't learn very much about nutrition in medical school. I was diagnosed with PCOS. It took me two years to get to that point, despite me being a medical doctor myself. And I see that often in clinic with women who come in, be that endometriosis or PCOS, and they've been told by a healthcare professional with a throwaway comment, oh, just cut out gluten, just cut out carbs, all these random non evidence backed things that they don't realize have a huge implication on women. Women are very unique and have unique nutritional requirements that change across the lifespan. You go through puberty, pregnancy and postpartum, perimenopause, menopause. So there's all these, what I like to call, important hormonal milestones that influence a woman's needs across the cycle. So what are the most important things that you wish people understood about this space? Hi, Hi, everybody. I'm Emily Capitalupo, WHOOP senior vice president of research algorithms and data. And today, I am joined by doctor Hazel Wallace. Doctor Wallace is a medical doctor and a registered nutritionist, and I do not think people realize how little nutritional training medical doctors get as part of their medical training. And so it really is special to have somebody who's doubly certified and really thinking about the intersection of these two fields that are highly related and, not enough thought about. So I'm so, so grateful that you're here and very excited for this conversation. Yeah. Me too. I'm really excited to be here. Thanks for having me. So just to give everybody a a quick rundown of what to expect over the next hour or so, doctor Wallace is a member of the WHOOP medical Advisory Board. We're so lucky to have her incredible expertise infused all over the product, and I think you're really gonna love hearing what she has to say. She specializes in women's health. She's written an incredible book called The Female Factor, which we will link in the show notes, and she's also the founder of a platform called The Food Medic. So why don't we start off there? What is The Food Medic? So I will try to give you the short story of a very long story, But as you mentioned in the introduction, I studied medicine, so did a conventional medical degree. And I was really excited to learn about nutrition and lifestyle within that degree because my backstory is I lost my father to a stroke when I was 14. And as it's a cardiovascular disease, even as a teenager, I knew that that was strongly related to our nutrition, our lifestyle, stress, activity. And so I guess somewhere deep down, I went into medicine for that reason, but you don't learn very much about nutrition in medical school. And I started the food medic while I was there …
