Midlife Mayhem

What if a cheap, well-studied supplement could specifically help the muscle most of us lose first after 50 — our legs?

That’s the finding I didn’t see coming this week, and it’s why I’m actually leading with something other than weight-loss medications for once!

In this episode of Midlife Mayhem, I’m breaking down five recent studies looking at creatine, weight-loss medications, muscle preservation, postmenopausal women, HIIT and resistance training.

And there’s one theme running through all five:

Muscle is kept by what you DO — not simply by what you take.

This was the one I didn’t know, and it might be my favorite finding.

A December 2025 meta-analysis looking at adults over 50 found that creatine combined with resistance training worked — and the lower body responded particularly well.

That matters enormously.

Your legs affect your balance, mobility, ability to get off the floor and everyday independence. They also contain a huge proportion of your total muscle.

There’s an old bodybuilding saying: “legs go first.”

Even people who never stop training can notice their legs becoming lighter as they age. I certainly have.

And what about the scale increase that puts so many women off creatine?

Yes, your weight can initially tick up. But that’s intracellular water, not body fat. Creatine pulls water into the muscle cell, which can actually make the muscles look fuller.

The other interesting finding was duration. The research suggested benefits were strongest with supplementation lasting 32 weeks or less, with effects appearing to diminish with longer continuous use.

My own long-standing protocol has been eight weeks on and five weeks off, so the idea of cycling creatine rather than simply taking it continuously was particularly interesting to me.

But remember the order:

Train first. Supplement second.

Creatine isn't going to build your legs while you sit on the sofa.

Now let’s get to the GLP-1 conversation.

Real-world research presented at the European Congress on Obesity in Vienna in 2026 followed 486 adults taking weight-loss medications and measured their body composition using clinical-grade bioelectrical impedance.

The headline was pretty encouraging:

Approximately 80–85% of the weight lost was fat.

That's very different from the frightening narrative that these medications automatically strip muscle from your body.

But there was an important distinction.

The people who preserved the most lean tissue were also doing the things I talk about constantly: eating adequate protein and resistance training.

The medication can help manage appetite.

It cannot lift the weights for you.

It cannot eat the protein for you.

You still have to give your muscles a reason to stay.

This study particularly caught my attention because it looked specifically at postmenopausal women taking semaglutide.

Lean mass initially declined — but then it stabilized.

And here's the interesting part:

Grip strength actually improved.

This is why we need to stop using the terms lean mass, muscle mass and strength as though they're interchangeable.

They're not.

Lean mass includes muscle, but it also includes glycogen, water, organs and connective tissue.

If somebody suddenly eats significantly fewer calories and carbohydrates, glycogen stores fall. The water stored with that glycogen falls too.

A body-composition scan can register that as a reduction in lean mass.

That does not mean the equivalent amount of actual muscle tissue disappeared.

So stop worshipping one number on a scale or scan.

Pay attention to strength and function too.

And grip strength deserves particular attention after 50 because it's an incredibly useful marker of how well we're maintaining strength as we age.

This one should destroy the idea that getting older means training has to become completely gentle.

Researchers at the University of the Sunshine Coast studied 120 adults with an average age of 72 and incorporated high-intensity interval training.

They preserved lean mass.

Now, that doesn't mean every 72-year-old should suddenly start doing hill sprints.

HIIT is relative.

Your version might involve:

An exercise bike

An assault bike

Battle ropes

A treadmill

Kettlebells

Bodyweight circuits

Walking is fantastic. Keep walking. Get your steps. Go outside and move.

But walking is not training.

If you want to keep muscle, the muscle needs a reason to stay.

Intensity provides part of that reason.

And more isn't necessarily better. You don't need HIIT every day. Two or three purposeful sessions a week can be plenty.

Finally, this study explains something I've watched happen with clients for more than three decades.

After 12 weeks of resistance training, participants were stronger, moved better and improved their everyday physical function.

Their body composition?

Barely moved.

That isn't failure.

It's what I call the adaptation window.

Strength, movement and function can improve on a completely different timeline from visible or measurable body-composition changes.

I've seen it countless times.

Someone trains hard for six or eight weeks, jumps on an InBody scan, doesn't see the change they expected and immediately thinks:

"This isn't working."

But it is working.

Your nervous system is adapting. You're producing more force. Your movement is improving. You're becoming stronger.

The body-composition changes can come later.

Don't mistake a delayed result for no result.

Five different studies, but the message is remarkably consistent.

Eat enough protein.

The emerging research around weight-loss medications and muscle is encouraging. Creatine continues to be fascinating, particularly for those of us over 50. And we have more evidence that challenging our bodies still matters as we get older.

But none of these things changes the fundamental rule:

You cannot outsource the signal your muscles need.

Midlife Mayhem with Joanne Lee

The scale says “lean mass.” Your strength tells the fuller story.

If you’re using a GLP-1, moving through menopause, or simply trying to stay strong as you get older, losing weight isn’t the only thing that matters. What you’re losing—and what you’re keeping—matters more.

In this episode of Midlife Mayhem, I’m connecting three conversations that are usually discussed separately: protein, GLP-1 medications, and HRT.

We’re talking about why the standard protein RDA may not be enough when your goal is preserving or building muscle, why I recommend around one gram of protein per pound of goal body weight, and what really happens when you dramatically increase protein intake.

I also break down one of the biggest concerns surrounding GLP-1 medications: muscle loss.

When a DEXA scan reports a drop in “lean mass,” that doesn't automatically mean you've lost that amount of muscle. Glycogen, water, organs and connective tissue are all included in lean mass—and rapid weight loss can change several of those very quickly.

That doesn’t mean muscle loss can’t happen. It absolutely can, particularly when calories drop dramatically without enough protein or resistance training. But this isn’t a problem invented by GLP-1 medications.

And then there’s HRT.

Hormone replacement therapy can be enormously valuable during menopause and may improve symptoms, sleep, recovery and quality of life. But HRT doesn't replace the muscle-building stimulus of resistance training.

The hierarchy is simple:

Resistance training provides the signal.

Protein provides the raw material.

Sleep, recovery, stress management—and, for some women, HRT—support the process.

In this episode, I also explain why your strength may be one of the most useful warning systems you have. If your weight is falling while your strength is holding or improving, that's very different from watching your weight fall while becoming progressively weaker.

Precision is the antidote to panic.

We’ll cover:

How much protein you may actually need in midlife

Why protein isn't the body-fat villain it's often made out to be

What “lean mass” on a DEXA scan actually means

GLP-1s, rapid weight loss and muscle preservation

Why resistance training becomes even more important when appetite is suppressed

Where HRT fits into the muscle-building equation

Why strength can tell you something the scale cannot

No pill, powder, injection or prescription does the reps for you.

Subject: Should Women Rule the World? (Depends Which Decade)

Hey there, this episode is dedicated to my SIL and brother who are "Stranded in Albuquerque," which sounds like a bad movie :)  Love you much and good luck getting home tomorrow....

New episode of Midlife Mayhem is live, and this one got away from me a little — in the best way. I started with a silly question (should women run the world?) and ended up going down a genuine rabbit hole on hormones, age, and what actually makes a good leader. Whether you listen or just want the highlights, here's the full rundown — grab a coffee, this one's a long one.

---

**THE QUESTION**

If you had to hand the keys to civilization over to women, no debate, no committee, just hand them over — would we actually be better off? My honest answer isn't "women, full stop." It depends enormously on which decade of a woman's hormonal life you're talking about. A 28-year-old, a 45-year-old white-knuckling through perimenopause, and a 62-year-old on the other side of it are basically running on different fuel, different brain chemistry, different priorities. And fair's fair — the men get the exact same treatment later on. If we're going to talk hormones and leadership, testosterone doesn't get a free pass.

One honest caveat before any of this: we're talking about averages here. There's enormous overlap between men and women on every trait below — plenty of men are more patient than the average woman, plenty of women are more reckless than the average man. Picture two bell curves stacked almost entirely on top of each other, with just the tails poking out on either side. That's what most of this research actually looks like. Averages tell us about tendencies at a population level. They don't tell you anything about the specific woman or man standing in front of you.

**PATIENCE ISN'T ONE THING, IT'S TWO**

Women tend to have a real, measurable edge on delayed gratification — waiting for the bigger payoff instead of grabbing the smaller one right now. That's a huge asset for long-horizon leadership: the difference between greenlighting a policy that won't pay off for ten years versus needing a visible win by next quarter to survive the news cycle. Some of this comes down to dopamine and reward sensitivity, both of which are influenced by testosterone — higher average testosterone tracks with more impulsive, immediate-reward-seeking behavior, in both sexes.

But patience for other people's behavior — frustration tolerance — is a totally different animal, and women don't score especially high there. Shorter fuse, faster escalation to interpersonal slights, even while showing more patience with numbers and long-term payoffs. So "patience" as a leadership trait is really two separate skills, and women only clearly win on one of them. There's also a workplace wrinkle worth mentioning: wanting more time or more data before committing to a decision is a real form of patience, but it's culturally read as weak, while slamming your hand on the table and deciding right now gets read as strong. Which one is actually better leadership? Depends entirely on whether you're in a five-alarm fire or making a call that'll play out over a decade.

**THE NEGOTIATION MYTH, BUSTED**

The old research (Linda Babcock's "Women Don't Ask") found women negotiate less assertively for themselves — smaller salaries, smaller raises, faster concessions, across multiple industries and countries. But later work, especially by Hannah Riley Bowles, found that gap almost completely disappears — or reverses — the moment a woman is negotiating on behalf of someone else: a client, a team, a department, a cause. Women assigned to advocate for someone other than themselves perform just as assertively as men, sometimes more so.

So it was never a competence gap or a confidence gap. It's a social penalty — women get judged more harshly by observers of both genders for self-advocacy specifically, sometimes called the "backlash effect," which creates a rational incentive to soften their own asks. And since leadership is almost always negotiating on someone else's behalf — a country, a shareholder base, a cause — this stereotype falls apart exactly where it matters most. There's a style difference worth a mention too: women tend to favor integrative, win-win approaches slightly more than purely winner-takes-all ones. In complex multi-party negotiations — trade deals, coalitions, multi-stakeholder mergers — that instinct finds trades a purely competitive negotiator would walk right past.

**TEND-AND-BEFRIEND VS. FIGHT-OR-FLIGHT**

The classic stress response — fight or flight — was studied almost entirely in men for decades, which is a genuinely embarrassing gap in the scientific record. When researchers (Shelley Taylor at UCLA) finally looked at women specifically, they found oxytocin and estrogen often produce a parallel stress response: de-escalate, calm the room, protect and support others, alongside or instead of pure fight-or-flight.

Neither response is objectively better. Tend-and-befriend is brilliant for de-escalation and keeping a room, a company, or a country from fracturing under pressure. Fight-or-flight is brilliant for fast, unilateral action when there's genuinely no time to build consensus — a real ten-second decision. A world run entirely by one or the other would have a real blind spot. Good leadership needs both responses available, ideally at the same table. There's a cortisol wrinkle too: men tend to show a sharper cortisol spike under status-threat stress (think public failure, being outperformed in front of peers), while women tend to show a sharper spike under relational stress (conflict, social rejection). Different triggers, equally real stress — neither sex has a monopoly on "the calm one."

**ARE WOMEN "TOO EMOTIONAL" TO LEAD?**

Not by the data. Men and women experience emotion with similar intensity on average — the real difference is what researchers call emotional granularity: how precisely you can name what you're feeling and why. "I'm angry" versus "I'm frustrated because I feel unheard, not actually angry with you." Better labeling is a regulation skill, not a lack of control — you genuinely can't manage an emotion you can't accurately name — and women are consistently better at it, partly because we're socialized from a young age to identify and express emotion more than men are. So the "too emotional" stereotype has it exactly backwards: the ability to explain the emotion is evidence of more control, not less.

**THE TWIST: WHICH WOMAN, AND WHAT AGE?**

This is the part I had the most fun with, because I don't think every woman over eighteen is hormonally interchangeable, and pretending otherwise is a little insulting to all of us.

- **30s — peak drive era.** Estrogen and progesterone at their most stable, dopamine-driven ambition running high. A lot of women describe this decade as their most confident, most externally-focused, "I will build the thing, get out of my way" period. Some of this is career stage and hard-won reps as much as hormones — but it lines up consistently with peak self-reported ambition. Founder energy.

If I had to pick one age bracket to hand the keys to? Late 50s to late 60s. Established, hard-won judgment. A documented drop in people-pleasing. Decades of pattern recognition that a 32-year-old, no matter how brilliant, simply hasn't had time to accumulate yet.

**NOW, FAIR'S FAIR — WHAT ABOUT THE MEN?**

Andropause is real but far fuzzier than menopause — there's no hard biological cliff-edge like ovulation stopping, and huge individual variation between men. Some seventy-year-olds have the testosterone of a forty-year-old, and vice versa. What's more consistently documented with age is a decline in cognitive flexibility: the ability to update a belief cleanly when new information arrives, instead of defaulting to an entrenched, previously-stated position. There's real cognitive science behind why people (not just men) get more rigid with age — confidence in existing beliefs tends to outpace accuracy, and reversing a public position starts to feel less like updating an opinion and more like losing a piece of yourself, sometimes called the "sunk cost of identity."

I even used the 2024 U.S. election as an accidental, genuinely even-handed case study — two candidates in their late 70s and 80s, each showing a different flavor of the same aging-brain story: one leaning toward processing-speed and verbal fluency decline, the other toward rigidity, refusal to concede facts, and reactivity under provocation. Not a partisan dig at either — genuinely useful precisely because they're two different failure modes wearing the same decade. If there's an "ideal" age for a male leader hormonally and cognitively, the data points to late 40s to mid-50s — old enough that impulsivity and dominance-seeking have settled, young enough that the brain still bends.

**SO, SHOULD WOMEN RULE THE WORLD?**

My honest answer, after all of that: not one woman, not one age. I'd build a three-person table — a driven woman in her 30s to build things from nothing, a decisive man in his late 40s or 50s for the fast unilateral call when there's genuinely no time for consensus, and a postmenopausal woman in her 60s to decide which of it was actually worth building, with nothing left to prove and no interest in being liked for the answer. If there's only one seat at the table, though? I'm handing the keys to the woman in her late 50s or 60s.

Come tell me which "era" you're in — I read every reply. And if you know a woman heading into her postmenopausal-zest years who needs a little permission to finally say the blunt, useful thing in the room — forward this to her. She's earned it.

Talk soon,

Hair thinning and hair loss are among the biggest frustrations I hear from women in midlife. Our hair can feel like part of our identity, so watching it become thinner, more fragile or seeing our scalp where we never used to see it can have a surprisingly big impact on confidence.

For this episode, I invited my longtime friend and client Sue McLea to share her own experience.

I’ve known Sue for years, so I knew what her hair looked like before. Over the last several months I started noticing the incredible difference in her hair — not simply longer hair, but visibly thicker hair and new growth in areas where she had previously experienced significant thinning.

Sue has now been using MONAT for approximately eight months and is also a MONAT ambassador. She joined me to explain what she experienced, what she uses and exactly how she uses it.

Sue began experiencing significant hair thinning around age 59–60, particularly around her temples.

It progressed to the point where she described having noticeable bald areas on either side of her head. Hairstyles she had worn for years suddenly became difficult because pulling her hair back exposed those areas.

Initially, she assumed this was simply another part of getting older.

Eventually, after watching the results her niece was experiencing with MONAT, Sue decided to try the products herself.

She was skeptical and gave herself a simple test:

Two months. If she didn't see a difference, she was done.

Instead, Sue says she began seeing tiny new “baby hairs” within approximately 30 days.

Eight months later, the difference in her hair is remarkable. Her hair has become so much thicker that she says she now needs to rethink her hairstyle because of all the new growth coming through.

One of the most interesting parts of our conversation was the emphasis on scalp health.

We spend enormous amounts of time and money taking care of the skin on our faces, yet most of us give very little thought to the skin underneath our hair.

Sue’s approach is to create a healthier scalp environment while also protecting the hair itself from breakage and damage.

Hair naturally moves through different stages — growth, resting and shedding — so the goal isn't simply to coat the existing hair and make it temporarily look better. The discussion centered around supporting the scalp and follicle environment while also protecting the hair you already have.

Sue didn't simply add another shampoo to her shower. She committed to a complete routine.

Sue uses Rejuveniqe Oil as a pre-shampoo scalp treatment approximately once or twice per week.

She applies the oil throughout the scalp, massages it in and brushes it through the hair. She often applies it at night and leaves it in before washing.

The oil contains a blend of plant-based oils and is designed to hydrate the scalp and hair while helping reduce dryness, frizz and breakage.

It can also be worked through the lengths of the hair rather than simply used on the scalp.

MONAT shampoo is highly concentrated, so Sue uses only about a dime-sized amount.

She emulsifies it thoroughly in her hands before applying it primarily to the scalp.

She then shampoos twice.

The first wash is used to remove product, oil and environmental buildup.

After rinsing thoroughly, she repeats the process. Sue says the second wash produces considerably more lather.

Rather than piling shampoo through the ends of the hair, the focus is the scalp.

Conditioner goes primarily from the ears down, rather than being applied heavily to the scalp.

Sue recommends allowing it to sit for several minutes before rinsing so it has time to work through the hair.

This was one of the most important products in Sue's routine.

Sue keeps the serum somewhere she will see it every day — initially beside her toothbrush — because consistency matters.

She applies a small amount directly to areas such as her temples and crown and gently massages it into the scalp.

It can be used on clean or dirty hair and Sue says it doesn't weigh the hair down.

Ingredients discussed during the podcast include Capixyl, melatonin and caffeine.

We also talked about DHT and its relationship with the hair follicle. Sue explained that Capixyl is incorporated into the formula specifically in relation to DHT and supporting the hair-growth environment.

For women going through menopause, this conversation becomes particularly interesting because hormonal changes can coincide with significant changes in hair density and quality.

This was actually the first MONAT product I personally tried, and I was immediately impressed.

RejuvaBeads is a leave-in treatment designed for damaged hair and split ends.

I've used just about every expensive leave-in conditioner, oil and treatment imaginable. Many make your hair feel nice initially but leave behind that unmistakable feeling that you've got product sitting on your hair.

This didn't.

My hair simply felt like better hair — silky, soft and healthy without feeling heavy or oily.

That's particularly important for me because my hair is naturally fine and fragile. Years of coloring and heat styling have made it prone to breakage, and since moving to Idaho I've also struggled considerably more with hard-water damage.

After using RejuvaBeads, my brush went straight through my hair.

That alone got my attention.

RejuvaBeads was discussed as helping bind and protect damaged areas of the hair shaft and can also be used as part of heat protection.

MONAT also has a Bond Support/Bond IQ range discussed in the episode for people dealing with significant damage from coloring, bleaching or repeated heat styling.

Sue also mentioned other products including a scalp scrub for people dealing with significant buildup, products specifically designed for curly hair, root-lifting products and a lightweight hairspray that allows the hair to remain touchable rather than stiff.

The point is that everyone's hair problem isn't identical — which is why Sue recommends taking the hair quiz rather than randomly choosing products.

Of course, products aren't the entire conversation.

Hair changes during midlife can occur alongside major hormonal changes.

We talked specifically about the decline in estrogen around menopause and how women can suddenly find themselves dealing with thinning hair at exactly the same time they're already navigating changes in body composition, skin, energy and confidence.

Hair loss can feel like one more thing being taken away.

And Sue's story really resonated with me because she initially did what so many people do:

She accepted it.

She assumed this was simply what happened as she got older.

Seeing her results challenged that assumption.

We also talked about something I think deserves considerably more attention: nutrition during weight loss.

If you're using a weight-loss medication or following any diet that dramatically suppresses your food intake, you still need to think about what nutrients you're providing your body.

Rapid weight loss combined with inadequate calories, protein and nutrients can be a terrible combination for maintaining muscle — and potentially your hair.

Losing weight while sacrificing muscle and hair isn't exactly the victory most women are looking for.

Whatever you choose to do for your hair should therefore sit on top of the basics: adequate nutrition, sufficient protein and taking care of your body from the inside as well as the outside.

This isn't purely a women's conversation.

Sue's husband had also spent considerable time and money trying different approaches for his hair, including more aggressive options.

He became so impressed with his own experience using the MONAT products that Sue jokes he now promotes them better than she does — and several of his friends have started using them too.

So while midlife female hair thinning was the reason for this conversation, men struggling with thinning hair may also want to speak with Sue about an appropriate routine.

We also addressed something I'd seen online: people saying their hair initially felt dry or frizzy after switching products.

Interestingly, Sue experienced this herself.

About two weeks after starting, she contacted her niece because her hair suddenly felt dry and frizzy. She described this as a short transition period after removing years of buildup from her previous products. She continued her routine and used the oil for additional hydration, and she says that phase passed.

Her advice is not to judge an entirely new hair routine after a couple of washes.

Give it some time.

We didn't avoid this.

MONAT uses a network/multi-level marketing model, and Sue is an ambassador.

I'm not financially involved with MONAT. I bought the products after seeing Sue's results and wanted her on the podcast because I know her, trust her and have personally watched the change in her hair.

Sue didn't approach me with a hard sell. In fact, much of our conversation was about how uncomfortable both of us can feel when enthusiasm for something that genuinely worked starts sounding like selling.

We also briefly discussed MONAT's history, previous controversy around the company, its emphasis on naturally based ingredients and its focus on avoiding certain ingredients in its formulations.

The company also offers wellness products alongside its primary haircare range.

One of my favorite parts of this episode actually goes far beyond shampoo.

It's about acceptance.

We hear:

"That's aging."

"That's menopause."

"That's just what happens."

And slowly people begin accepting things that make them feel less and less like themselves.

Sue said something that stuck with me: improving her hair hasn't only changed her hair.

It made her want to take better care of herself again.

She started styling her hair again. Paying attention to it. Enjoying it.

In her words, she feels like she's falling in love with herself again.

That's why this conversation matters.

Hair may sound superficial until you're the person watching yours disappear.

If you're dealing with thinning, shedding, breakage, hair that simply won't grow, or you're completely confused about which products would be appropriate for your hair, Sue is happy to help.

You can send her photographs, take her hair quiz, message her with questions or arrange a quick conversation so she can help you determine which products make sense for your particular hair.

Sue is very clear that she can't guarantee anyone else's results — but she can help you understand the options and build an appropriate routine.

And if you're listening rather than watching, I definitely recommend watching this episode on YouTube as well so you can actually see Sue's hair and the areas of new growth we're talking about.

The difference is pretty extraordinary.

As always, my goal with these conversations isn't to tell you what you have to do. It's to introduce you to information, products and people I've encountered that may help you have a better midlife — and beyond.

Because getting older doesn't mean we simply have to accept everything getting worse.

Midlife Mayhem — Episode Show Notes

Hey there,

Two Instagram posts sent me down a rabbit hole this week, and I couldn't wait to bring it to you.

Post one: a woman says if you can't wrap your fingers around your wrist, you're "big boned" — not overweight, just built bigger. Post two: if your thigh isn't over 24 inches around, you'll apparently live longer. As someone who's trained for 44 years, can squat 200lbs, and still only measures 20 inches on a good day... I had thoughts.

So this episode is a myth autopsy. Both claims have real research behind them — that's exactly why they spread so fast. But both get flattened and distorted by the time they hit your feed. In this one, I break down:

I also measure my own wrist and thigh live on the mic, so you can hear exactly how the numbers play out on someone who's spent a lifetime training. Grab your own tape measure before you hit play — you'll want to check your own numbers along the way.

This week's shoutout: I'm filming with my friend Sue this week about hair thinning in midlife and what actually helped her — keep an eye out for that one on YouTube and right here on the podcast.

If you’re fit, strong and taking care of yourself — but suddenly feel like your skin didn’t get the memo — this episode is for you.

Crepey skin. Sagging skin. Wrinkly skin. Skin that suddenly seems too big for your body.

It is one of the biggest frustrations I hear from women and men in midlife. You can be in fantastic shape, yet suddenly you’re thinking twice about sleeveless tops because of your upper arms. You’re noticing the skin above your knees. Your chest looks different. The backs of your hands look older.

And sometimes it genuinely feels as though it happened overnight.

So in this episode of Midlife Mayhem, we’re going deep into what is actually happening to our skin as we move through our 40s, 50s, 60s and beyond — and, more importantly, what the science tells us we can potentially do about it.

And yes, this is a science-heavy episode.

Because over the past year I have gone rather spectacularly down the rabbit hole of regenerative skincare while developing my Blue Theory™ range — particularly my Regenerative Face Serum and the new GHK-Cu Body Booster.

Collagen makes up a huge proportion of the structure of our skin, but we begin losing it surprisingly early in adulthood. That decline becomes particularly noticeable around perimenopause and menopause as estrogen falls.

At the same time, we're losing some of the substances responsible for keeping skin hydrated and plump, including hyaluronic acid. Elastin becomes damaged. And the biological signals telling our skin to repair and rebuild itself become quieter.

That last part became incredibly important to me.

When I started formulating Blue Theory, I wasn't interested in creating something that simply sat on top of the skin and made it look shiny for a few hours.

I wanted to understand the ingredients involved in the skin's own repair and regenerative processes.

And that search led me to GHK-Cu.

Don't let the name put you off.

GHK is simply a tiny peptide made from three amino acids: glycine, histidine and lysine.

Cu is copper.

Put them together and you have the copper peptide GHK-Cu.

The story behind it is fascinating. GHK was identified in human plasma in the 1970s, and researchers became interested in its relationship with cellular activity and tissue repair.

What really sent me down the rabbit hole was discovering that our natural levels of GHK decline dramatically as we age — at the same time that our skin becomes less capable of repairing and regenerating itself.

Suddenly, GHK-Cu wasn't simply another trendy skincare ingredient to me.

I wanted to know everything about it.

In the podcast I walk you through some of the research that originally stopped me in my tracks.

We talk about studies examining topical GHK-Cu and its relationship with collagen production, skin firmness, laxity, texture, pigmentation, density and thickness.

And this is an important distinction I make in the episode: the research that initially got me excited about GHK-Cu was topical research.

People frequently ask me about injectable GHK-Cu. I've used injectable GHK-Cu myself, but that's not what this particular conversation is about.

For skin, I became fascinated by what researchers were seeing when GHK-Cu was applied topically.

This was another big moment for me.

A 2023 study examined GHK-Cu combined with lower-molecular-weight hyaluronic acid and reported a dramatic increase in type IV collagen synthesis in human dermal fibroblast cultures.

Type IV collagen is particularly interesting because it is involved in the junction between the epidermis and dermis — an area that becomes weaker as skin ages.

But I make an important distinction in the podcast.

That dramatic number came from laboratory research — not a clinical trial showing someone's skin suddenly producing 25 times more collagen.

Cell-culture results don't translate one-for-one to what happens when we put a serum on our bodies.

Nevertheless, the documented interaction between the ingredients fascinated me and became one of the reasons I wanted GHK-Cu and hyaluronic acid together in my formulations.

I had wanted to create a GHK-Cu product specifically for the body for quite some time.

The obvious answer seemed to be a body lotion.

So I made one.

Then a cream.

Then a body butter.

And I didn't love any of them.

Not because they were necessarily bad — but because we're all incredibly particular about body lotions.

Some people want something rich and buttery. Others hate that feeling and want something incredibly light. I use different products myself depending on the season.

Then I had the obvious-in-hindsight idea:

Why am I trying to reinvent everybody's favorite body lotion?

Why not create the concentrated skincare component and let you add a few drops to the body lotion or cream you already love?

That became the Blue Theory GHK-Cu Body Booster.

It's a lightweight, water-based serum featuring GHK-Cu alongside hyaluronic acid, NAG and other supporting ingredients.

You can apply it directly to the skin or simply mix a few drops into your favorite body moisturizer.

And there's a reason it's water-based.

GHK-Cu is water-soluble. I would have loved to simply put it into my Face & Body Oil, but it wouldn't remain properly incorporated in an oil formula.

So instead, the two products can complement one another while remaining separate formulations.

Because I wanted the face formula to do more.

The Blue Theory Regenerative Face Serum combines GHK-Cu with a group of complementary ingredients selected for different roles in mature skin.

One of those is PDRN — polydeoxyribonucleotide.

PDRN is derived from purified DNA fragments and has attracted enormous attention in regenerative and Korean skincare. It has been studied extensively in tissue repair and wound-healing applications.

And again, I explain an important caveat in the episode: much of the strongest human evidence for PDRN comes from medical and injectable applications.

Topical PDRN research is growing, but we shouldn't simply assume an injectable medical result automatically translates to putting a cosmetic serum on your face.

I still find the biology incredibly interesting — particularly because PDRN and GHK-Cu appear to influence regenerative processes through different mechanisms.

This might be one of my favorite underrated skincare ingredients.

N-acetylglucosamine — NAG — is naturally present in skin and is involved in the production of hyaluronic acid.

In other words, rather than only applying hyaluronic acid, we're also interested in providing a building block the skin uses in its own hydration processes.

Research has also examined NAG for hydration, pigmentation, texture and other visible signs associated with sun-damaged skin.

For midlife skin, that combination is particularly interesting because we're often dealing with moisture loss and pigmentation at the same time.

That's why you'll find NAG in both my Face Serum and Body Booster.

Allantoin isn't the trendy ingredient you're going to see splashed across TikTok.

It's been around for years.

And that's precisely the point.

Allantoin is widely used for its soothing properties and its ability to support the skin barrier — something I think we completely underestimate.

We can become so obsessed with acids, exfoliation and aggressive "anti-aging" treatments that we forget we're dealing with a living protective barrier.

Especially as we get older, more isn't necessarily better.

I wanted ingredients in the formula that support the skin while the more interesting regenerative ingredients are doing their thing.

The same thinking applies to panthenol — provitamin B5.

Panthenol isn't particularly sexy either.

But it helps support moisture retention and barrier function.

Because what good is putting hydrating ingredients into your skin if your compromised skin barrier is allowing water to escape straight back out?

Sometimes the ingredients doing the quiet supporting work are every bit as important as the ingredient with its name on the front of the bottle.

We've all heard of this one.

There's a reason it's everywhere.

Hyaluronic acid attracts and retains water and helps give skin that hydrated, plumper appearance we associate with younger skin.

But one of the things I discuss in this episode is molecular weight.

Different sizes of hyaluronic acid behave differently in the skin, and that became especially interesting when I started looking at the research combining lower-molecular-weight hyaluronic acid with GHK-Cu.

This is really where everything comes together.

I kept finding products built around one hero ingredient.

A GHK-Cu serum.

A PDRN product.

A hyaluronic acid serum.

And I kept thinking:

Why are we stopping there?

My approach with Blue Theory was to look at ingredients that could play complementary roles within a compatible formulation.

GHK-Cu as the anchor.

PDRN providing another regenerative pathway.

NAG supporting hydration-related processes and helping address the appearance of pigmentation.

Hyaluronic acid for hydration and its relationship with GHK-Cu.

Panthenol supporting moisture retention and the barrier.

Allantoin helping keep mature and sensitive skin calm.

Different jobs. One overall philosophy.

I love them.

But that doesn't mean everything belongs in the same formula — or necessarily on the skin at exactly the same moment.

GHK-Cu has formulation and pH considerations, which is why I didn't simply throw every famous skincare active into one bottle.

If you're using strong vitamin C, retinoids or acidic products, I explain in the episode how I prefer to separate them from my GHK-Cu products — for example, using them at different times of day rather than layering everything together.

The Blue Theory Face & Body Oil actually started life as a face oil.

I love facial oils, so I created a blend of multiple oils together with vitamins C and E.

Then my husband Kevin started using it in the shower.

Gallons of it, apparently.

I tried it myself and thought, Hold on. This is fantastic.

We live in Idaho. It's dry, the water is hard, and my skin absolutely notices it.

A little oil on damp skin after the shower — or mixed into body lotion — completely changed how my skin felt.

So the little face oil became the Face & Body Oil, and because Kevin and I were getting through it at an alarming rate, I created a much larger size as well.

Aging skin isn't simply about wrinkles.

For many of us, wrinkles aren't even the thing bothering us most.

It's the crepiness.

The thinning.

The sagging upper arms.

The skin above the knees.

The chest.

The backs of the hands.

The sudden change in texture that seems completely out of sync with how strong, healthy and fit we still feel.

And that's why I became so interested in regenerative skincare in the first place.

I don't think the answer is chasing overnight miracles.

I think it's understanding what has actually changed biologically — and then looking intelligently at the ingredients and research that may support mature skin.

That's exactly what I wanted Blue Theory to be about.

Repair. Renew. Rejuvenate.

If you've made it all the way through this particularly science-heavy episode, I'm either extremely interesting or you've been driving for a very long time.

Either way, I appreciate you!

Midlife Mayhem

What happens when dental work that has lasted more than 30 years finally needs replacing — and you realize you don't necessarily want to have it done in the United States?

In this episode of Midlife Mayhem, I’m sharing my entire experience of traveling to Istanbul, Turkey, for extensive dental work: why I started looking overseas, why my first attempt in Cancún ended with me getting on a plane and coming home without having anything done, and the research that eventually led me to Esnan Dental Hospital in Istanbul.

My dental history is a little complicated. I had bridges, crowns and veneers from a relatively young age, and much of that work had been in my mouth for an incredible 32 years. It still looked pretty good from the outside, but receding gums, sensitivity and a broken tooth made me realize I didn't want to spend the next decade simply patching things up one tooth at a time.

Most importantly, I talk about the part that's difficult to understand from photographs and online reviews: the experience of being there.

Dental tourism can feel incredibly overwhelming. You're trusting someone with your face, your smile and your health in another country. I spent about a year researching my options, traveled to Cancún and came home without treatment, contacted multiple clinics and asked a ridiculous number of questions before making my decision.

I couldn't be happier that I eventually chose Esnan Skyland in Istanbul.

For decades, we were terrified of dietary fat. Everything was low-fat, fat-free or reduced-fat, and eating fat was almost automatically associated with gaining body fat.

Then the pendulum swung.

We learned more about carbohydrates, blood glucose and insulin. Low-carb and ketogenic diets exploded in popularity. Avocados, nuts, olive oil, cheese and other high-fat foods went from foods we feared to foods we were actively encouraged to eat.

But have we swung a little too far in the other direction?

One of the biggest mistakes Joanne sees today is the assumption that because dietary fat has very little immediate effect on blood glucose—and doesn't require a large insulin response—it somehow doesn't matter when it comes to body composition.

In this episode of Midlife Mayhem, Joanne explains where that misunderstanding came from and why “insulin stores fat” does not mean “without insulin, fat can't be stored.”

She follows dietary fat from your plate through the lymphatic system and into circulation, explains the role of lipoprotein lipase (LPL) in fat storage, and looks at why a perfectly healthy low-carb meal can quietly become extraordinarily high in calories.

You'll also hear why the combination of high fat + high carbohydrate is particularly easy to overconsume, how the thermic effect of fat differs dramatically from protein, and why the body's response to excess calories depends partly on which macronutrients those calories come from.

Joanne also introduces the relationship between NNMT, 5-Amino-1MQ and nutrient partitioning, a subject she'll explore in greater depth in a future episode.

Dietary fat isn't the enemy.

But it isn't a free food either.

We've gone from one extreme—being terrified of fat—to another, where adding olive oil, avocado, nuts, cheese and other fats barely seems to count because they're considered “healthy.”

They absolutely can be healthy.

But healthy fat is still fat, and quantity still matters.

Sometimes what looks like an incredibly clean, low-carb diet has quietly become an extremely high-fat, high-calorie diet without you even realizing it.

5-Amino-1MQ

Most people assume body image struggles during puberty are a girls' issue.

They're wrong.

In this episode of Midlife Mayhem, Joanne shares why so many teenage boys are quietly struggling with their bodies—and why parents, coaches and even healthcare professionals often miss the signs.

Drawing on current research and over 30 years of coaching experience, Joanne explains the powerful hormonal changes happening during puberty, why boys compare themselves so harshly, and why many are judging themselves long before their bodies have reached their true muscle-building years.

This is an important conversation for anyone raising, coaching or supporting teenage boys.

Why teenage boys experience significant emotional changes during puberty—not just aggression.

The remarkable 20-fold increase in testosterone during adolescence.

Why muscle development continues long after height growth has finished.

Why two boys of the same age can be years apart biologically.

The hidden impact of comparison in the gym, on sports teams and on social media.

What research tells us about body dissatisfaction and muscle dysmorphia in adolescent males.

Warning signs that normal motivation may be becoming unhealthy rigidity.

Why emotional vulnerability in boys is often misunderstood.

Practical advice for parents and coaches on supporting teenage boys without adding pressure.

Why "you're not behind—you’re simply mid-build" may be one of the most important messages a teenage boy can hear.

Puberty isn't simply a period of growth—it's one of the biggest hormonal transitions the human body ever experiences.

Many boys believe they should already look like fully developed young men, when in reality their greatest years for building muscle often don't begin until their late teens and early twenties.

Understanding this timeline can dramatically reduce unnecessary anxiety, comparison and self-criticism.

As Joanne reminds us:

Your body isn't behind schedule. It's simply mid-build.

Testosterone and male puberty

Peak muscle-building years

Body image in adolescent boys

Muscle dysmorphia (research overview)

Emotional regulation during adolescence

Coaching teenage athletes

Parent and coach communication strategies

If you know a parent, grandparent, teacher, coach or anyone working with teenage boys, please share this episode. It's a conversation that deserves far more attention.

Everyone talks about muscle loss with weight loss medications.

Some people mention "Ozempic face."

But almost nobody talks about hair loss—and perhaps they should.

In this episode, Joanne explains why hair may actually be one of the first things your body sacrifices during periods of rapid weight loss, calorie restriction, or inadequate protein intake. Whether you're using GLP-1 medications, following a very low-calorie diet, recovering from bariatric surgery, or simply trying to lose those final stubborn pounds, understanding what happens to your hair could change how you approach your nutrition.

The good news?

Hair loss isn't inevitable—but preventing it requires planning.

Joanne breaks down the biology behind hair growth, why shedding often appears months after the trigger, what the latest research is showing about GLP-1 medications and hair loss, and, most importantly, what you can do to dramatically reduce your risk while still reaching your body composition goals.

Losing weight shouldn't mean sacrificing your hair.

Whether you're using weight loss medications or losing weight naturally, protecting your nutrition—especially your protein intake—isn't optional. It may be one of the most important investments you can make for your muscle, your metabolism, and your long-term health.
