Whether you’re seeking to shed excess weight, gain lean muscle, or simply feel more vibrant, this podcast is your trusted companion in the pursuit of a healthier, stronger, and more resilient you. Welcome to a new era of limitless possibilities in midlife body transformation. ”Hi I’m Joanne, and I have been coaching body composition for over 30 years. I’ve worked with household names that you know, and I have worked with thousands of people in my group coaching programs. I was a pro bodybuilder in the 90’s with a top 10 physique in the world, but I only knew how to be in shape and out of shape. That frustration led me on a fascinating path of self-study where I found all the answers I could have asked for and more. But I had to dig for the answers, and I have my own ideas on why those answers are not mainstream and why the weight loss industry fails you, but I will save that for a Midlife Mayhem episode.

  • LEAN MASS IS NOT MUSCLE MASS

    LEAN MASS IS NOT MUSCLE MASS
    2026/09/28

    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:

    1. Resistance training provides the signal.

    2. Protein provides the raw material.

    3. 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.

  • Better Legs After 50 - do tell

    Better Legs After 50 - do tell
    2026/10/01
    Better Legs After 50! What 5 New Studies Say About Muscle, GLP-1s & Creatine 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. 1. Creatine after 50 — the legs responded best 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. 2. Weight-loss medications: 80–85% of the weight lost was fat 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. 3. Semaglutide in postmenopausal women: strength went UP 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. 4. HIIT preserved lean mass — at an average age of 72 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. 5. You can get stronger before your body composition changes Finally, this study explains something I've watched happen ...

  • Crepey Skin, Sagging Skin & the Science of GHK-Cu

    Crepey Skin, Sagging Skin & the Science of GHK-Cu
    2026/08/23
    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. Why does our skin suddenly change so much? 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. So what on earth is 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. GHK-Cu, collagen and mature skin 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. Then I found the GHK-Cu + hyaluronic acid research 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. And that's how the Body Booster was born 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 ...
