- 32 minutes 49 secondsLosing Weight and Losing Hair? Here's What to Do with Dr. Katherine Nolan
It’s one of the most distressing side effects people can experience during a weight loss journey, yet almost no one warns you about it.
At first, it’s easy to dismiss. Then it starts showing up everywhere: in the shower drain, on your pillow, and in your hands every time you run your fingers through your hair.
In this episode, I’m joined by board-certified dermatologist and hair loss specialist Dr. Katherine Nolan to break down why rapid weight loss can trigger shedding, how the hair growth cycle actually works, which labs to ask your doctor for, and when medication might make sense.
We’ll also talk through some of the biggest myths, including why expensive serums and biotin supplements are not usually the fix people hope they are.

27 April 2026, 7:00 am - 23 minutes 51 seconds8 Health Basics That Beat Every Supplement, Tracker and Program
I've been thinking a lot lately about how much we overcomplicate our health. Tracking 15 different metrics, obsessing over the perfect supplement, debating which programme is best — while the simple basics just... aren't happening. I catch myself doing it too.
So in this episode, we're rewinding right back to basics with the 8 things that actually matter for your health. Not all at once, not perfectly, just one small area at a time until it sticks.
If you feel like you've been doing all the things but still aren't making the progress you expected, consider this your reset. Simple, practical, and actually doable.

20 April 2026, 7:00 am - 33 minutes 41 secondsTired, Hungry, and Stuck? How Poor Sleep Affects Hormones, Cravings, and Weight Loss with Dr. Funke Afolabi-Brown
You might be blaming your hormones, your medication, or yourself... when the real problem could be your sleep.
Sleep is one of the most overlooked parts of metabolic health. And when it's off, everything feels harder. You feel hungrier. Your cravings get stronger. Your energy drops. Your blood sugar is harder to manage. Progress slows down, even when you feel like you're doing everything right.
In this episode, sleep medicine physician Dr. Funke Afolabi-Brown explains why sleep matters so much, what could be disrupting yours, and why waking up exhausted is not something you should just accept.

13 April 2026, 7:00 am - 19 minutes 16 secondsPlateaued? Try These 5 Things Before You Clamp Down Harder
When the scale stops moving, the instinct is to restrict more, exercise harder, and white-knuckle your way through it. I get why this is a common reaction, but it's not what your body actually needs to break through.
In this episode, I explain why the answer to a plateau is almost never "do more and eat less." It's usually something far more holistic, and a whole lot kinder. So instead of clamping down harder, I’ll walk you through five overlooked strategies that get things moving again, without making you miserable in the process.

6 April 2026, 7:00 am - 19 minutes 25 secondsGLP-1s at Every Age: What You Should Actually Be Watching For
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.

30 March 2026, 7:00 am - 43 minutes 4 secondsHow Your Nervous System Hijacks Your Eating (and How to Get It Back) with Jane Pilger
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.

23 March 2026, 7:00 am - 40 minutes 29 secondsJacqui Cook on GLP-1 Weight Loss, Maintenance Fears, and Letting Go of Diet Rules
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.

There’s a lot of noise online about semaglutide, sudden vision loss, and scary eye complications. If you’re taking a GLP-1 (or thinking about it), you might be wondering: Am I putting my vision at risk?
In this episode, I sit down with Dr. Mina Farahani, a cornea, cataract, and refractive specialist, to get the real story on GLP-1s and eye health. We cover what the latest data actually says about vision loss risk, why a baseline eye exam matters before starting treatment, what symptoms should never be ignored, and the simple habits that protect your eyesight long-term.

2 March 2026, 8:00 am - 20 minutes 39 secondsRestarting GLP-1s? 5 Reasons It Feels Harder This Time
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.

23 February 2026, 8:00 am - 57 minutes 37 secondsPerimenopause, 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.
