  • 340 Pounds Down: Jamie Selzler's Four Rules for Lasting Change

There are moments in our work that stay with you long after the conversation ends. My interview with Jamie Selzler was one of those moments. At 652 pounds, Jamie's world had become frighteningly small. Short walks left him breathless, and the haunting reality that people his size rarely lived past 50 forced him to face where his life was heading. What followed wasn't a quick fix or dramatic intervention. It was a complete transformation built on small promises, deep self-compassion, and the support of GLP-1 medication. Over three years, Jamie lost more than 340 pounds. But what moved me most wasn't the number on the scale, it was how he rebuilt his relationship with himself. In this powerful conversation, Jamie shares his four rules for lasting change, why he keeps a notebook with hundreds of handwritten wins, and why he refuses to set a goal weight. We talk about forgiving yourself, keeping promises to yourself, and why the happier life isn't waiting at some distant finish line—it's happening right now, in every small choice you make.ReferencesYou can follow Jamie's journey on TikTok: @JamSelz or Instagram: @jselzler.Season 2 of Behind the Curtain is now LIVE!

  • Your Friday Five: No More Candy Chaos
    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. This special Halloween Your Friday Five episode is all about removing the candy scarcity mindset and setting yourself up for success. For many people, Halloween can feel like a slippery slope — candy in the house, kids bringing home buckets of it, and old habits kicking in. But it doesn’t have to derail you.In this episode, I cover:How to create candy neutrality. Candy isn’t forbidden, and it’s not scarce. Halloween candy is available all year long. When we remove the “forbidden fruit” mentality, the brain stops screaming for it. Remind yourself you can have it tomorrow, next week, or whenever you choose — there’s no urgency.Why eating real food first matters. When you have a balanced meal with protein, fiber, and healthy fats before eating candy, your blood sugar is steadier, your dopamine hit is lower, and you’re far less likely to feel out of control. Eating real food first changes how the candy impacts your body and your decision-making.Plan it, don’t police it. Instead of strict rules, create gentle boundaries that make you feel empowered. For example: decide to choose your favorite two pieces, savor them slowly, and wait until you’re home to enjoy them. This moves you from restriction to intention — and that’s where you regain control.And if things don’t go as planned, remember: one night won’t undo your progress. Give it a five-second funeral, wake up the next day, and go right back to your normal, balanced habits.Your power doesn’t come from perfection — it comes from intention.All of the information on this podcast is for general informational purposes only.

  • Raising Body-Confident Kids When You're Still Figuring It Out with Dr. Whitney Casares

You want to raise kids who feel confident in their bodies and have a healthy relationship with food. But what happens when you're still figuring that out yourself?Maybe you catch yourself labeling foods as "good" or "bad." Or your child comes home saying something they picked up at school or TikTok ("big back," "fat," "calories")...and your stomach drops. You want to respond in a way that builds confidence, not confusion. But between your own history with dieting, the mixed messages online, and the constant pressure to "get it right," it feels impossible to know what to say.In this episode, I'm joined by pediatrician and author Dr. Whitney Casares, who shares how to navigate food and body conversations with kids at every age. She explains the division of responsibility approach, why authenticity beats perfection, and how to handle those uncomfortable moments at the pediatrician's office. Plus, she tackles the controversy around new pediatric guidelines and the shame surrounding GLP-1 medications. ReferencesDr. Whitney Casares' book: My One of a Kind Body: The Ultimate Guide to Caring for Me (Available October 21st)Website: modernmommydoc.com (includes free pediatrician visit guide)Instagram: @modernmommydocSeason 2 of Behind the Curtain is now LIVE!
