How To Protect Your Brain in Midlife with Barbie Boules

SHOW NOTES

Okay, this episode genuinely changed how I think about my health.

Because somewhere along the way, women got taught that if we stayed thin enough, worked hard enough, and maybe survived on coffee and cortisol, we’d somehow be “healthy.” Meanwhile, our brains were over there quietly begging for vegetables and sleep.

Today I’m talking with cognition dietitian Barbie Boules, and this conversation blew my mind in the best possible way. We dig into the real connection between midlife, metabolic health, hormones, sleep, stress, and cognitive decline. We talk about why women are twice as likely to develop Alzheimer’s disease, what’s actually happening during perimenopause brain fog, and how to tell the difference between normal forgetfulness and something more serious.

And before you spiral because you forgot why you walked into a room, Barbie explains why that’s probably not dementia. It might just be that you’re exhausted, overstimulated, under-slept, stressed out, and trying to keep twelve tabs open in your brain at all times. Relatable.

We also talk about the internet’s favorite pastime: terrifying women into thinking their brains are “eating themselves” during menopause. Barbie clears up what the science actually says, what’s overhyped, and why the basics still matter more than all the trendy supplements and panic-inducing wellness content.

One of my favorite parts of this conversation was Barbie’s take on health becoming less about shrinking ourselves and more about protecting the thing that literally runs our entire lives: our brains. It was hopeful, practical, empowering, and honestly kind of a relief.

Also, she gave some of the best weight loss advice I’ve heard in years. No shame. No unrealistic timelines. No punishment. Just sustainable, sane behavior change.

And yes, we also talk about the one food category that research shows can make your brain function like it’s ELEVEN YEARS younger.

Turns out your grandmother was onto something with the leafy greens.

WHAT’S INSIDE:

  • Why women are more vulnerable to Alzheimer’s and what researchers are learning about hormones and brain health
  • The difference between normal midlife brain fog and signs of cognitive decline
  • The lifestyle habits that most strongly protect your brain, including sleep, exercise, stress management, and nutrition
  • Why Barbie says focusing on brain health can improve your entire body composition and long-term health

This episode reminded me that health is so much bigger than how we look.

Your brain is your personality, your memories, your creativity, your relationships, your ability to experience joy. And for so many of us in midlife, this is the first time we’re realizing that maybe the goal isn’t just to be smaller or “good” anymore. Maybe the goal is to stay sharp, strong, energized, connected, and fully alive for as long as possible.

And honestly? I found that incredibly motivating.

So I’d love to know: what’s one small thing you could start doing now to support your future brain health?

DM me on Instagram. I genuinely want to hear it.

Episode 110: What Every Woman Over 40 Needs To Know Before Lifting Another Dumbbell

EPISODE 110: 

What Every Woman Over 40 Needs To Know Before Lifting Another Dumbbell

SHOW NOTES

Alright, friends, let’s talk straight: if you’re over 40 and still slogging through random workouts, obsessing over fad diets, or clinging to those cute little 5lb dumbbells… we need to have a heart-to-heart.

This episode is the replay of a live presentation I gave to over 2,600 women (yeah, the Zoom room actually maxed out, wild). And I didn’t hold back. Because here’s the truth: what worked in your 20s isn’t going to cut it anymore. And no, it’s not because you’re “broken” or “too old.” It’s because most of us are making the same three mistakes that keep us stuck spinning our wheels.

We’re going deep into why muscle is the closest thing you’ve got to a fountain of youth and why building it is about so much more than looking jacked in your tank top (although that’s a solid perk). From metabolism to brain health to literally not falling on your face in your 70s, this stuff matters.

I’ll walk you through the three shifts you have to make if you want to get strong, stay healthy, and actually see results from the work you’re putting in. Spoiler: it’s not about trying harder; it’s about finally doing the right things in the right way.

So if you’ve ever thought, “Ugh, I’m working so hard and nothing’s happening…” this one’s for you. You are stronger than you think. And it’s time to prove it.

WHAT’S INSIDE:

  • Why strength training is non-negotiable for women over 40 (hint: it’s way beyond “toning”)
  • The three most common mistakes that keep women stuck and how to fix them once and for all
  • The truth about protein, carbs, and what your body actually needs to fuel muscle growth
  • Real-life transformations from women who ditched diet culture and finally got strong AF

So let me ask you… what would getting strong mean for you? More confidence in the gym, finally feeling good in your body, or maybe just proving to yourself that it’s not “too late”? Whatever it is, I want to hear it. Come hang with me on Instagram and tell me what being strong AF looks like in your world.

Episode 109: Pilates vs Weight Training, Muscle Confusion + More! with Dr. Allan Bacon

EPISODE 109: 

Pilates vs Weight Training, Muscle Confusion + More! with Dr. Allan Bacon

Pilates vs Weight Training, Muscle Confusion + More! with Dr. Allan Bacon

SHOW NOTES

You know those fitness clichés that just won’t die? Like “muscle confusion keeps your body guessing” or “lifting weights makes women bulky”? Yeah, we’re coming for them.

This is part two of my chat with Dr. Allan Bacon, strength coach, medical pro, and professional BS buster. (If you missed part one, go back. It’s chef’s kiss myth-busting gold about metabolism, influencers quoting mouse studies, and why women are not just small men.)

In this round, Allan and I take on the internet’s favorite myths, starting with muscle confusion. Spoiler: it doesn’t give you better results. It mostly just makes you sore. We also tackle the never-ending Pilates vs. weights debate because no, Pilates does not magically give you “long, lean muscles” (that’s genetics, babe). And no, weight training will not turn you into the Hulk by accident.

We get into why women think they bulk up too quickly (hint: it’s just the pump, not instant muscle gain) and why sticking with weight training is one of the best things you can do for fat loss, metabolism, and avoiding injuries down the line. Your muscles are basically little carb sponges, so the more lean muscle you build, the more pizza you can eat without it going straight to your hips.

And because Allan can’t resist a peek into the future, he also calls out the next big scam about to flood your feed: concierge pill mills. Yep, the wellness industry always finds a way.

This episode is equal parts myth-busting, science, and pep talk. Bottom line: lift the damn weights. You’re not broken, you’re not doomed, and your body is capable of way more than you think.

WHAT’S INSIDE:

  • Why “muscle confusion” is mostly hype
  • The truth about Pilates vs. weight training
  • What’s really behind women “bulking up” too fast
  • The next big fitness and wellness scam to watch for

Let’s get honest for a sec: are you letting fear of “bulking up” or falling for influencer hype hold you back from training the way you really want? Imagine what would change in your body and your life if you dropped the BS and just went for it. Let me know on Instagram, I love hearing your takeaways.

Episode 108: The Problem with “Women Are Not Small Men” with Dr. Allan Bacon

EPISODE 108: 

The Problem with "Women Are Not Small Men" with Dr. Allan Bacon

The Problem with "Women Are Not Small Men" with Dr. Allan Bacon

SHOW NOTES

You know that phrase that’s everywhere right now, “Women are not small men”? Well… it’s true. And also? It’s become the perfect little hook for some people to sell you complete and utter BS.

In this episode, I sit down with Dr. Allan Bacon, yes, the guy who trains Arnold Classic competitors, publishes in scientific journals, and also works with regular humans who just want to get stronger without losing their minds, to bust some of the biggest myths floating around women’s health and fitness right now.

We get into the shady tactics “menopause influencers” are using to prey on women’s very real experiences (and why some of these folks are making you just as stuck as the old-school bro science ever did). Allan explains how to tell the difference between what’s actually happening in your body and what’s just Instagram fear-mongering.

And spoiler: some of the things you think are “hormones” might actually be your habits. Which is great news, because habits are something we can change.

We also talk mouse studies (yep, apparently you’re a large mouse now?), why cortisol isn’t the enemy it’s made out to be, and a brutal but brilliant “10-day diet” test to check if your metabolism is actually broken.

If you’ve ever been told to only do one type of workout because “menopause” or if you’ve wondered whether all this hormone talk is a legit wake-up call or just a very expensive con, this one’s for you.

WHAT’S INSIDE:

  • Why “women are not small men” is true and how it’s being used to con you
  • How to spot influencer fear-mongering vs. actual science
  • The truth about metabolism during menopause (and the habits that matter most)
  • Why your workout program probably doesn’t need to be “hormone-specific” to work

So let me ask you this. What’s keeping you from feeling good in your body right now? Is it your hormones, or is it the sneaky little habits that crept in without you noticing? If you’ve ever felt stuck, frustrated, or just plain confused about what the hell to do next, you’re not alone. Shoot me a DM on Instagram and tell me what’s going on for you. Let’s get you moving in the right direction.

Episode 98: Creatine! Collagen! Cortisol! with Dr. Lauren Colenso-Semple

EPISODE 98: 

Creatine! Collagen! Cortisol! with Dr. Lauren Colenso-Semple

Creatine! Collagen! Cortisol! with Dr. Lauren Colenso-Semple

SHOW NOTES

Metabolism “broken”? Cortisol through the roof? Syncing your workouts with your menstrual cycle like it’s a lunar ritual? Let’s unpack the madness.

Welcome to the 2025 Fitness Complex—where the marketing is louder than the science and your confusion is the business model.

Lauren Colenso-Semple, certified slayer of fear-based wellness B.S., is here to cut through the collagen powders and influencer jargon and serve up some actual facts.

Keep calm and remember the six C’s: Credentials, Consensus, Conflict of Interest, Common Sense, Confirmation Bias, and Communication Style.

Still clinging to creatine? It's not a magic potion, so stop prioritizing it over your other healthy routines. 

Worried menopause is stealing your muscle? Blame aging, not your hormones. Resistance training is the only thing that fights back.

Cycle syncing? Honestly, it’s just a socially acceptable way to ghost your workout routine. And inconsistency is the real hormonal chaos.

Supplements and biohacks won’t save you. Showing up and doing the work will.

No one wants to hear they have to work harder… but sorry, that’s still the truth.

Whatever physical activity you actually like? Do that. And then do it again.

The myths, the shady sales pitches, the body-obsessed bait—tune it out.

And as Lauren wisely says… stay safe out there.

WHAT’S INSIDE:

  • Actually build muscle during menopause (before AND after).
  • The real deal on cycle syncing.
  • How to spot sciency bullshit.
  • Keep calm and remember the 6 Cs.

Feeling personally victimized by the pseudo-health industry? It's time to seek personally individualized real health and fitness plans…NOT the one-size-fits-all magical fixes. Did we bust some myths you’ve fallen for? Let me know on Insta!
