    Elaine is 76, works out twice a week…and still hates exercise. So why does she never want to miss a session? 
    In this episode, we talk about what changed when Elaine stopped chasing a certain look and started chasing strength instead. From knee replacements and lipedema to feeling stronger, steadier, and more independent, this is a refreshingly honest conversation about movement, aging, and why you don’t have to love the workout to love what it gives you.

    The $40 Billion Electrolyte Trend: Do You Actually Need Them?

    Electrolyte packets are everywhere right now. But just because they’ve become part of the wellness uniform, does that mean they’re actually helping your body… or are you just adding a lot more sodium than you realize?
    In this episode, I react to a physician’s take on the electrolyte craze and break down what’s really inside those trendy packets. We’ll look at why most people probably don’t need them every day, and how “healthy” habits can quietly stack up in ways you may not expect.
    I’ll also explain when electrolytes do make sense, and why the “boring basics” like water, whole foods, movement, and managing stress still do far more heavy lifting than the latest wellness product.

    Why Your Brain Is Wired to Crave (And How to Retrain It) with Dr. Glenn Livingston

    What if the voice telling you, “Just have one… you deserve it… start again tomorrow” isn’t really you at all?
    Clinical psychologist Dr. Glenn Livingston calls it the “Food Monster”: a radically different way to understand cravings and that feeling of being hijacked by food. After nearly 20 years battling overeating himself, he realized that understanding why he ate wasn’t the same as changing the behavior.
    Instead of seeing cravings as proof you’re weak or lack willpower, Glenn reframes them as a survival response. One that can be interrupted and retrained, so you can stop fighting yourself every time a craving hits.
    Once you hear cravings explained this way, you won’t be able to unhear it.

    No Appetite on a GLP-1? What to Eat When Nothing Sounds Good

    What do you do when your GLP-1 turns your appetite all the way down, and even your favorite foods get a big "meh"?
    It might feel like a win at first. But if you're barely eating, your energy, strength, mood, and nutrition can start paying the price.
    In this episode, we talk about how to make eating easier when hunger disappears: simple go-to foods, less decision-making, flexible meal timing, and how to make sure a low appetite doesn’t turn into under-fueling.
