    GLP-1s at Every Age: What You Should Actually Be Watching For

    Send a Text Message. Please include your name and email so we can answer you! Please note, this does not subscribe you to our email list, it's just to answer if you have a questions for us.

    When it comes to GLP-1 medications, your age and stage of life matter more than a lot of people realize. What works for your body at 25 won't work the same way at 45... and definitely not at 65.

    Yet somehow, most people are still being treated with a one-size-fits-all approach. Same advice, same dosing strategy, same conversation — regardless of whether you're navigating PCOS in your twenties, perimenopause in your forties, or trying to protect your muscle mass in your sixties. And that disconnect might be exactly why things feel harder than they should.

    Tune in to find out what I watch for at every stage of life, so you can make sure what you’re doing is helping, not holding you back.

    How Your Nervous System Hijacks Your Eating (and How to Get It Back) with Jane Pilger

    Send a Text Message. Please include your name and email so we can answer you! Please note, this does not subscribe you to our email list, it's just to answer if you have a questions for us.

    For 25 years, Jane Pilger couldn't figure out why she couldn't stop binge eating. It wasn't until she uncovered the one piece no one had ever explained to her that things finally started to change.

    And it had nothing to do with willpower… or food. It was her nervous system.

    In this episode, binge eating coach Jane Pilger returns to break down something that doesn't get nearly enough attention: how the state of your nervous system drives your eating behavior.

    Jane shares her simple framework for mapping your nervous system, why you’re more likely to reach for food when you’re stressed, exhausted, or overwhelmed—and how to start responding differently in those moments.

    Jacqui Cook on GLP-1 Weight Loss, Maintenance Fears, and Letting Go of Diet Rules

    Send a Text Message. Please include your name and email so we can answer you! Please note, this does not subscribe you to our email list, it's just to answer if you have a questions for us.

    For decades, Jacqui Cook lived in a cycle many women know all too well: losing weight, gaining it back, and starting over… always wondering why nothing seemed to stick. Food was her love language, life kept getting in the way, and no matter how hard she tried, maintaining her progress felt impossible.

    Everything changed after a wake-up moment that led her to try a GLP-1 medication. Now, 115 pounds lighter, Jacqui shares the real, honest side of her journey: navigating maintenance, facing the fear of regain, letting go of guilt, rebuilding lost muscle, and learning to live fully in her body. She also reveals the diet habit she finally ditched, and why it turned out to be one of the best decisions of her life.

    You hit your goal weight. So now what...?

    For a lot of people, maintenance feels like uncharted territory. And without the right mindset, it's easy to either white-knuckle it or slowly drift back to old patterns. 

    In this episode, I walk through five things I think everyone needs to know about maintenance: why it's not a new phase, how to find the weight you can actually live at, how to monitor without judgment, what to do when your metabolism adapts, and what long-term GLP-1 use really looks like.

    Restarting GLP-1s? 5 Reasons It Feels Harder This Time

    Send a Text Message. Please include your name and email so we can answer you! Please note, this does not subscribe you to our email list, it's just to answer if you have a questions for us.

    Back on your GLP-1 medication… but confused why it isn’t working this time?

    Lots of people stop these medications for valid reasons. Cost, side effects, pregnancy plans, or simply because things were going well and it felt like the right time to try managing without them. But when weight creeps back on and you restart, it can feel really frustrating when results don’t look the same.

    In this episode, I talk through why that happens. Factors like muscle loss, metabolism changes, weight regain patterns, and higher stress levels can all change how your body responds the second time around. If you’re feeling stuck or wondering what changed, this episode will help you make sense of what’s going on and figure out your next steps without beating yourself up.

    Perimenopause, GLP-1s, and What's Actually Affecting Your Sex Drive with Dr. Kristen Wolfe

    If you've noticed your sex drive has tanked, whether from GLP-1s, perimenopause or menopause, postpartum changes, or simply the mental load of being a woman in 2026… you're not imagining it. And you're definitely not “broken”.

    In this episode, I talk with Dr. Kristen Wolfe, OB-GYN and women's sexual health specialist at Evermore Women's Health. She breaks down why 85% of women experience desire differently than we're told and what’s actually behind the drop in libido so many women experience.

    We talk about how hormones, stress, medications, busy lives, and relationship dynamics all play a role, and why so many women blame themselves for changes that are completely normal. Dr. Wolfe also shares practical strategies that can help, from understanding responsive desire and reducing the “brakes” on libido, to scheduling intimacy, practicing mindfulness, and using tools like arousal creams or medical treatments when appropriate.

    Understanding PCOS: From Diagnosis to Long-Term Health with Dr. Sabrina Huq

    Send a Text Message. Please include your name and email so we can answer you! Please note, this does not subscribe you to our email list, it's just to answer if you have a questions for us.

    If you’ve been told you have PCOS (or suspect you might), you’ve probably been left with more questions than answers. It’s one of the most misunderstood conditions out there, and a lot of people are misdiagnosed, under-treated, or given the same tired advice: “just lose weight” or “take the pill and see.” 

    In this episode, I’m joined by endocrinologist Dr Sabrina Huq to clear things up. We talk about what PCOS actually is, how to get properly diagnosed (including the key lab tests), and why spotting it early can change your long-term health, including your ability to have a healthy, natural pregnancy. Tune in for Dr Huq’s practical approach to managing PCOS through food, movement, sleep and stress, plus when meds like metformin or GLP-1s might make sense.

    The Cost of GLP-1s is Forcing Switches: Can You Maintain Your Results?

    Send a Text Message. Please include your name and email so we can answer you! Please note, this does not subscribe you to our email list, it's just to answer if you have a questions for us.

    What happens when the medication that's finally helping you is no longer affordable?

    If you've had success on Mounjaro or Zepbound but need to switch to a more affordable option like Ozempic for maintenance, you're probably wondering: will this actually work? And if semaglutide didn't help you before, the idea of going back can feel risky, especially when you're worried about regaining weight, increased food noise, or losing the progress you've worked so hard for.

    In this episode, I break down when switching medications for cost makes sense, when it's likely to backfire, and what your options are if semaglutide is the only affordable option.

    Welcome back to Your Friday Five — a quick roundup of products I’ve been loving lately, especially when it comes to easy ways to add more protein.

    Here’s what’s in my current rotation:

    Devotion Nutrition Protein Powder – My go-to for protein hot chocolate. Mix hot water, a splash of milk or milk alternative, one scoop of protein, and blend for a cozy 20-gram protein treat. If you use code DrMatthea at checkout you save. 

    Meal Boosters Savory Protein Powder (White Cheddar) – Perfect on popcorn for movie nights. Tastes just like classic white cheddar seasoning and adds easy protein without sacrificing flavor.

    Joyburst Protein Soda – said the name wrong on the episode but correctly written here, 20 calories, 4 grams of protein per can. Found at Costco and surprisingly became a regular favorite for both adults and kids.

    Cookbooks I recommend:

    Skinnytaste High Protein: 100 Healthy, Simple Recipes to Fuel Your Day
    Devotion Nutrition Cookbook

    Have a great weekend — I’ll see you Monday as we head into February!
