    Your Friday Fave: The One Question That Changes Everything

    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 week’s Your Friday Five centers around a single question—one that has the power to shift your mindset, your habits, and the way you evaluate progress. I came across it in a video from Jamie Seltzer (linked below), and it stopped me in my tracks: “If every week was like last week, would I be closer to my goal?” In this episode, I break down why this question works, how it cuts through perfectionism, and why zooming out to that 30,000-foot view gives you more clarity than obsessing over small slip-ups. We talk about what to do if your answer is “yes,” what to do if your answer is “no,” and why understanding why you had an off week is more important than beating yourself up for it. You’ll also hear a simple way to build this question into your weekly routine—whether that’s a Friday afternoon alarm, a sticky note, or a reminder tucked into your planner—so it becomes a guide instead of a forgotten moment of inspiration. This episode is your permission to release perfection, get honest without judgment, and steer yourself gently back on track.

In this New Year edition of Your Friday Five, we’re talking about the ONE strategy that consistently transforms my patients’ nutrition—and my own. Winter is here, the days are darker, and this is the time of year when energy dips and cravings rise. Instead of fighting it, let’s set you up to feel better from the inside out. In today’s episode, I walk you through my simple “2 protein + 2 fiber” system that keeps your meals effortless, balanced, and ready when you need them—not after hunger hits. I share exactly how I prep my fridge, the card-stock list I keep posted, and the easy breakfast, lunch, dinner, and snack combos that make nutrition feel doable (even on your busiest weeks). You’ll also hear how to grab my free “Prepared” PDF and the lentil red sauce (“Steve”) recipe, plus how to comment on social to get them sent straight to your DMs. This episode is all about real-life support—not perfection. When you have go-to meals ready, you give yourself a fighting chance for better energy, better mood, and better consistency as you move into the year. Links: → Note I miss-spoke on the episode and it's comment "sauce", not Steve, to get the red sauce recipe. Also not instead of ground beef I use a can of pre-cooked lentils.

In this year-end episode, I’m sharing the top five lessons that transformed my own health—and the health of so many patients I’ve worked with.

You’ll hear about how my tastes evolved (yes, your palate really can change), how movement became a true non-negotiable, why structure creates more freedom—not less—and the mindset practices that kept me anchored during the busiest seasons. I also share the patterns I’ve seen repeatedly in patients navigating GLP-1 medications, metabolic healing, emotional eating, and long-term weight management. This episode wraps the year with grounded wisdom, compassion, and tools you can start using today. In This Episode, You’ll Learn: Why your taste buds genuinely change over time—and how to create the conditions for that shift.The identity shift that makes daily movement automatic (and non-negotiable).How simple routines and structure actually reduce stress, emotional eating, and evening overeating.The mindset training required to maintain weight loss and navigate busy seasons with less friction.The role of community and support in sustaining long-term behavior change.Why building momentum—not perfection—was the biggest theme in both my life and my patients’ successes this year.All of the information on this podcast is for general informational purposes only.

    Your Friday Five: Restarting GLP-1s Postpartum—What to Expect

    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 week’s Friday Five tackles a question many women quietly wonder about:  “What should I expect if I restart Mounjaro after pregnancy and breastfeeding?” Whether you paused your GLP-1 for pregnancy, breastfeeding, or simply life circumstances, coming back to it after many months brings up a lot of unknowns. In this episode, I break down what typically happens, what we actually know from emerging research, and most importantly—why postpartum women need close, compassionate medical support. Inside the episode, we explore: 1. What current guidelines say about GLP-1s, pregnancy, and breastfeeding The traditional recommendation is stopping GLP-1s two months before trying to conceive and waiting until you’re done breastfeeding to restart. But I also share a recent small study looking at semaglutide and its transfer into breast milk—and what that means (and doesn’t mean) for real-life decisions. 2. Why restarting after long-term use often looks different If you were previously on Mounjaro for 6–24 months, your body typically: tolerates the medication more easilycan often titrate up more quicklyexperiences fewer early side effects  Some of this is physiologic, some behavioral—because you’ve already learned hydration, fiber strategies, and the day-after-injection do’s and don’ts.3. The postpartum period is the “fourth trimester”—and it changes everything Exhaustion, unpredictable schedules, stress, hormones, sleep deprivation… postpartum is not just a season. It’s a vulnerable season. This is why you should never “go cowboy alone” when restarting medication. A skilled clinician helps prevent: excessive restrictionmetabolic overwhelmworsening moodtipping into depression or anxietyextreme titration that backfires4. How ongoing support during pregnancy impacts your restart I share examples from my own clinic:  Some women stay with me through pregnancy—not for weight loss, but for structure, nutrition support, and a stable relationship with food.  Those women often find it much easier to restart postpartum because they never disconnected from caring for their bodies. 5. The good news: most women feel relief when they restart Once medically cleared and supported, many women say: their appetite becomes manageable againtheir mental load decreasestheir urges and cravings quiet downthey finally feel like they have helpAnd that’s the whole point: to feel supported, not stressed. If you’re in this season, I’m rooting for both your health and your baby’s h All of the information on this podcast is for general informational purposes only.
