Episode 103
Thursday, 15 October, 2026

What if insulin resistance is quietly driving inflammation, weight gain, and thyroid dysfunction years before blood sugar ever looks abnormal?In this episode of Modern Thyroid and Wellness, McCall McPherson sits down with endocrinologist Dr. Alessia Roehnelt for an in-depth conversation about insulin resistance and why it can be such an important marker of long-term metabolic health.Dr. Roehnelt explains how insulin functions in the body, what happens when insulin resistance develops, and why chronically elevated insulin can contribute to inflammation, weight gain, metabolic dysfunction, and disease progression.They also explore the bidirectional relationship between insulin resistance and hypothyroidism, including how thyroid dysfunction can worsen metabolic health and how insulin resistance can complicate thyroid function and treatment.🔑 In This Episode:What insulin resistance is and how it developsWhy insulin resistance may appear before prediabetes or type 2 diabetesCommon physical and metabolic signs of insulin resistanceAcanthosis nigricans, carb sensitivity, and rapid weight fluctuationsThe relationship between insulin resistance and hypothyroidismHow insulin resistance may affect thyroid hormone absorption and conversionWhy fasting insulin can provide useful information beyond A1c alone“Normal” vs. optimal fasting glucose, insulin, and A1c valuesWhy population-based lab ranges do not always reflect optimal healthThe role of vitamin D in metabolic and hormonal healthFatty liver markers including AST and ALT🏃‍♀️ Improving Insulin SensitivityDr. Roehnelt and McCall discuss foundational strategies including:Consistent, restorative sleepStrength and resistance trainingReducing refined carbohydratesPairing carbohydrates with protein and fatUsing continuous glucose monitors to better understand personal responsesStrategic intermittent fasting when appropriate💊 Medications DiscussedMetforminImproves insulin sensitivityHas a long history of clinical useCan be a cost-effective early interventionGLP-1 receptor agonistsReduce appetite and slow gastric emptyingLower liver glucose productionImprove insulin signalingMay help reduce inflammation in appropriate patients🌿 Key TakeawaysInsulin resistance can often be improved when identified early.“Normal” lab values do not always tell the entire story, and weight gain is far more complex than calories in versus calories out.One of the biggest themes in this episode is that inflammation connects metabolic dysfunction, thyroid disease, and autoimmunity, making individualized, whole-body evaluation incredibly important. 📖 Pre-Order Take Back Your Thyroid + Get a Free BonusPre-order McCall McPherson’s new book, Take Back Your Thyroid, and choose one free bonus:🎓 Thyroid Empowered Course — a $399 valueOR🩺 $150 off a new patient visit at Modern Thyroid Clinic👉 https://book.modernthyroidclinic.com/📍 Connect with Dr. Alessia RoehneltWebsite & Practice:https://www.endohealthdoc.comInstagram:https://www.instagram.com/endohealthdoc/Facebook:https://www.facebook.com/alessia.roehnelt📲 Follow McCall McPherson & Modern Thyroid and WellnessModern Thyroid Clinic:https://modernthyroidclinic.com/McCall McPherson:https://www.mccallmcpherson.com/Instagram:https://www.instagram.com/mccallmcphersonpa/YouTube:https://www.youtube.com/channel/UC0_JyQdBAJwYT3rMDsvyriwFacebook:https://www.facebook.com/McCallMcPhersonPAC/X / Twitter:https://x.com/thyroidexpert
