Weight, Muscle, Metabolism, and Moms: What We’re Getting Wrong About Health with Matthea Rentea

I was at the grocery store with my nine-year-old. She'd had a hard day (the class bully had gone after her) and she wanted everything. Cinnamon Toast Crunch. Brioche with Nutella.

I'm also talking about why I think the "let kids eat whatever they want, whenever they want" message that's everywhere in the body-positive parenting space is missing something really important.Read more.Mentioned in this episode:New Book!

When we become doctors, lawyers, or teachers, there are exams, certifications, and years of preparation. But when we become parents, we’re handed a newborn and sent home.Dr. Debbie Raphael—a child, adolescent, and adult psychiatrist—became a mother at the same time she began her child psychiatry fellowship. That unusual overlap gave her a rare opportunity: she was learning the science of child development at the exact moment she was living it. Over time, she began journaling about that experience, eventually turning those reflections into her forthcoming book, Carry My Strength, which explores the emotional and psychological layers of parenting.In this episode, Dr. Whitney and Dr. Raphael talk about the emotional realities of parenting—from the identity shifts that happen when we become parents to the ways our own childhood experiences shape how we raise our kids.Read more.

In this episode, Dr. Whitney Casares sits down with Dr. Jay Gargus and Dave Justus from NeuroQure to discuss the power of early clarity when it comes to autism detection and why earlier intervention can fundamentally change outcomes for children and families.Dr. Gargus explains the science behind early behavioral therapies and why their impact goes far beyond short-term skill-building. Research shows that early, evidence-based interventions can lead to measurable, lifelong improvements in IQ, social skills, independence, and educational placement, often determining whether a child can thrive in mainstream education or requires ongoing specialized support.The conversation also tackles a critical and often overlooked issue: access. Dave Justus shares the personal motivation behind NeuroQure’s work and explains why the test is being launched at cost, with installment plans and employer subsidies, while the team works toward insurance coverage. The goal is to prevent families from losing precious years waiting for answers.------Our kids are growing up surrounded by misinformation about health, beauty, and worth.
