Postpartum after 38 is metabolically different. Here's why, and what to do about it.

If your body isn't bouncing back after having a baby the way you expected, you're not imagining it. Recovery is genuinely harder in your late 30s and 40s, and for a growing number of women, the reason is the overlap between postpartum recovery and early perimenopause.

I joined Sarah Trott on the Fourth Trimester Podcast to talk about the physiology behind this, the labs that get missed during the six to 24 month postpartum window, and the practical interventions that help.

We cover the Fuel, Move, Recharge, and Regulate pillars of the Perimenopause Matrix and dig into:

• Why insulin resistance increases as estrogen and progesterone decline, and how that affects postpartum recovery
• How to tell whether your symptoms are typical postpartum recovery or early perimenopause
• What MHT is and why the conversation looks different when you're also breastfeeding or trying to conceive
• The testing gap: why fasting insulin shows metabolic changes up to 10 years before fasting glucose moves
• What elevated triglycerides are signaling about your carbohydrate tolerance
• The cortisol-blood sugar connection and what it means for sleep-deprived new mothers
• Protein targets, plate building, and nutrient-dense food strategies for postpartum recovery
• Strength training, pelvic floor timing, and how muscle is your best longevity investment
• Circadian light, morning sunlight, and the 10-minute daily regulation habit that supports cortisol and melatonin balance

This episode is for you if you've had a baby after 38, if you're navigating both fertility and perimenopause, or if you're supporting women in this unique life overlap.

This episode is personal.

I'm currently navigating an IVF cycle while in perimenopause, and finding support for both at the same time has been one of the most exhausting and illuminating experiences of my health journey. I spent a full year searching for a doctor in New York City who would hold both pieces. Every single one told me they couldn't help. They did fertility, or pregnancy, or perimenopause. No one did the crossover.

I share the moment one doctor finally looked me in the eyes and said "I believe you," why I ended up in bodybuilding forums researching my own hormone protocol, and what happened most recently with my IVF cycle that made me want to hit record immediately.

In this episode:

• Why fertility and perimenopause absolutely coexist, and why medicine has cognitive dissonance about it
• The real data on birth rates in women over 35 and 40 (it will surprise you)
• What it took for me to advocate for hormonal support while navigating IVF
• The reproductive endocrinologist training gap that reveals exactly how broken this system is
• Why the labor of becoming your own citizen scientist is not a personal failing; it is a system failing
•

Is it willpower or is it biology? What protein actually does in a perimenopause body.

Protein is having a moment. Again. But what does the research actually say, and why does it matter more in perimenopause than at almost any other time in your life?

In this episode of Mornings with Megan, I break down the protein conversation through the lens of the Perimenopause Matrix, specifically the FUEL pillar and how it connects to blood sugar regulation, muscle preservation, and hormone health.

In this episode:

• Why perimenopause increases insulin resistance, even in women eating healthy diets, and what the SWAN study tells us about this
• How protein supports blood sugar stability and stimulates natural GLP-1 production in your body
• The difference between complete and incomplete proteins, and why serving size tells the real story
• What the research says about protein in ultra-processed foods (yes, we talk about the protein PopTart)
• How much protein to aim for, where to start, and why 90 grams is my clinical entry point
• What women on GLP-1 medications need to know about lean mass loss and why protein is non-negotiable
• The ethics and access conversation that gets consistently left out of the protein debate

I also share my own history with hypoglycemia and blood sugar chaos at 19, because I think it matters for you to know that I have lived this, not just studied it.

This is not a "eat more chicken" episode. This is the full picture.

Your bones are not just a structural frame. They are a living, metabolically active organ system that produces hormones, participates in glucose metabolism, and communicates with your immune system. And in perimenopause, the hormonal shifts that affect your mood, your sleep, and your body composition are also shifting the balance of your bone remodeling.

This is the final episode in the three-part Move pillar series, and it covers: what bone actually is, what happens to it in perimenopause, why osteoporosis and osteopenia are not inevitable, and exactly what the research says you can do about it right now.

This is episode 3 of 3 in the Move pillar of the Perimenopause Matrix, a six-pillar framework for understanding and navigating perimenopause.

If there is one thing I want every perimenopausal woman to do, it is this: lift weights.

Not for aesthetics. For your metabolism, your blood sugar, your bones, your cardiovascular health, and your longevity. The research on this is not ambiguous.

In this episode we cover:

• Why resistance training is cardiovascular medicine, including the mortality data that should change how you think about strength training
• The under-muscled woman: what she looks like in labs, why she exists, and how to make sure you don't become her
• What happens to muscle stem cells when estrogen declines, and why mechanical load is one of the only signals strong enough to compensate
• The heavy vs. light weight debate: what Dr. Lauren Colenso-Semple's research at McMaster University actually shows, where Dr. Stacy Sims' argument for heavy lifting fits, and how to apply it practically
• Progressive overload explained simply, including all the levers you can use beyond just adding weight
• A sex-based physiology note on fatigue and rest between sets that changes how you structure a session
• How to start from absolute zero, including the three-minute workout that started my own training journey

Part of the Move Pillar of the Perimenopause Matrix

Doing everything right with exercise and still feeling exhausted, not recovering well, or holding weight around your middle?

This one is for you.

This is episode one of a three-part movement series. Today we cover the full cardio framework for perimenopause.

What we cover in this episode:

🧠 The stress cup model: why cortisol dysregulation (both too high AND tapped out) changes everything about how you should be moving

💪 Why your high-intensity class may not be your friend right now, and how to think about it

⏱ Dr. Martin Gibala's published protocols from McMaster University: the SIT protocol (10 minutes, 60 seconds of hard work) and the HIIT 10x1 (20 to 25 minutes total), with equipment options for every level

📚 How Dr. Stacy Sims (Next Level) and Gibala land in the same place from different research angles

❤️ Megan's personal story of cortisol burnout and why she needed someone else to hold her to the protocol she couldn't give herself

🚶 Why walking is genuinely medicinal: the blood sugar evidence, the 2025 Lancet longevity data (7,000 steps, 47% lower mortality risk), and the 2024 Lancet RCT on walking and pain

📊 Your real-world VO2 max test, no lab required

You've probably been rucking your whole life. You just didn't have the word for it.

In this episode, Certified Nutrition Specialist and perimenopause expert Megan Pfiffner breaks down why load-bearing movement - the kind you're already doing with groceries, kids, bags, and stairs - is one of the most powerful tools available for women in perimenopause. This episode focuses on the Move pillar of the Perimenopause Matrix™, and why it's the most underutilized lever for protecting your muscle, bone, blood sugar, and nervous system during this stage of life.

In this episode:

• What rucking actually is and why women have been doing it for centuries
• The Harvard study that shows your belief about exercise changes your body
• Why estrogen and testosterone decline makes load-bearing movement urgent in perimenopause
• The bone density truth: maintaining vs. improving, and why both rucking and lifting matter
• Why rucking is one of the only cardio options that doesn't spike cortisol
• The female endurance advantage under load — and the biology behind it
• How to start this week with zero equipment
• How rucking supports all six pillars: Move, Fuel, Recharge, Regulate, Connect, and Clean in the Perimenopause Matrix™

If you've ever crashed at 3pm, woken up at 2am anxious and sweating, or watched your cravings go completely off the rails in the week before your period - your blood sugar is involved. And in perimenopause, managing it gets harder. Not because of anything you're doing wrong. Because of what your hormones are doing.

In this episode I'm walking you through continuous glucose monitoring - what it actually shows you, how to use it as a learning tool rather than a source of anxiety, and what two weeks of my own personal CGM data revealed about food, stress, sleep, movement, and sex.

I also break down HbA1c, why it should never be read as a solo marker for insulin resistance, and how the Fuel pillar of the Perimenopause Matrix connects to every other pillar in the system - Regulate, Recharge, and Move.

Brain fog. Forgetfulness. The terrifying thought that you might be losing your mind. If you've experienced any of this in your late 30s or 40s, this episode is the one I've been wanting to make for a long time.

This week on Mornings with Megan, I'm sharing the story of a client who saw four specialists and had extensive neurological testing — because her symptoms were so significant she genuinely feared she had dementia. She's 39. What she actually has are early perimenopause signs driven by low progesterone, the hormone most responsible for sleep, mood stability, anxiety regulation, and self-regulation.

We also go deep on what is actually happening in the perimenopausal brain — drawing on the neuroimaging research of Dr. Lisa Mosconi (author of The XX Brain) and the mindfulness science of Ellen Langer (author of The Mindful Body) — to offer a reframe that changes everything: your brain isn't declining. It's reorganizing.

In this episode you'll learn why progesterone is usually the first hormone to become unreliable in perimenopause, how the Regulate and Recharge pillars of the Perimenopause Matrix™ are affected, why forgetfulness is often your brain triaging under stress, and three practical tools to help you work with your brain instead of fighting it.

"I don't have time" might be the most common thing Megan hears from clients. In this episode, she breaks down why time scarcity is almost never a time problem and how the same tools that power the Perimenopause Matrix can help you find breathing room you didn't know you had.

Drawing on the work of time management expert and NYT bestselling author Laura Vanderkam, Megan covers five strategies for making the most of the time you already have: tracking your time, setting a bedtime as a hormonal health tool, Friday priority planning, exercise snacks, and the universally controversial tip that gets the most pushback from everyone. (It's about hobbies.)

This episode connects to the Recharge, Regulate, Connect, and Move pillars of the Perimenopause Matrix - because for women in perimenopause, chronic depletion isn't just an energy problem. It's a hormonal one. Rest and joy are part of the protocol.
