If you’ve practiced long enough, you’ve seen this pattern. Two clients present with nearly identical labs. You design the same protocol expecting similar progress, and the outcomes couldn’t be more different. One improves quickly. The other barely moves.In this episode, Dr. Ritamarie dives into metabolic readiness, why some protocols work beautifully for some clients and don’t move the needle for others. She explains how metabolic chaos (not dysfunction), and the body's readiness to respond to interventions, are the real game-changers.This episode is a must-listen if you’ve ever been puzzled by why the "right" protocol fails despite clear lab data. Discover how shifting from reactive to readiness-based thinking can transform your clinical outcomes.What’s Inside This Episode? Why sequencing plans is more important than just following lab dataThe critical gap between identifying dysfunction and understanding readinessHow metabolic chaos creates resistance, while readiness fosters responseWhy the same protocol can have opposite effects depending on the body’s stress, inflammation, and signaling statusThe order that must come before progress happensHow metabolic readiness shifts clinical thinking from chasing markers to stabilizing systemsResources and Links:Download the full transcript hereDownload our FREE Metabolic Health Guide here.

You’ve run the labs, designed the perfect plan, and your client is following it… but progress stalls. Why is that happening?In today’s episode, we dive into why even the most well-designed functional protocols can fall short. It's not that your plan was wrong. It’s about sequencing. The body doesn't respond to everything at once, and when we miss the critical regulatory hierarchy, even the best plans can stall.We’ll unpack the gap between lab data and clinical outcomes, and why understanding readiness and context is the missing link for sustainable transformation.If you've ever had a case where the labs looked fine, the protocol seemed right, but the results didn’t follow through, this episode will change how you approach your work.What’s Inside This Episode?Why lab data alone won’t tell you what the body is truly ready to healThe hidden cause of stalled protocolsHow understanding the body’s regulatory hierarchy can unlock treatment successWhy addressing multiple dysfunctions at once often derails progressThe game-changer: why context and readiness are key to true healingThe critical next step: how to know when the body is actually ready to respondResources and Links: Download the full transcript here.Download our FREE Metabolic Health Guide here.

Despite the rising popularity of high-protein, low-carb diets and macro tracking, metabolic disease is still on the rise. So why isn’t the perfect macro balance solving the problem? In today’s episode, Dr. Ritamarie explores why focusing solely on macronutrients isn’t enough to restore metabolic health. While macros are important, they’re only one piece of the puzzle. The real key lies in understanding how the body responds to those inputs and why your clients might still struggle even when they’re following the "perfect" protocol.What’s Inside This Episode? Why just tweaking macros doesn’t address the deeper metabolic issuesThe hidden truth: metabolic health is driven by how the body responds, not just what you eatWhy insulin resistance, thyroid issues, and weight struggles persist even with the "right" macrosHow chronic stress, inflammation, and nervous system imbalances shift how the body handles foodThe vital shift from focusing on numbers to understanding the body’s signalsWhy looking at metabolic health through a systems lens changes everything in practiceThe real question practitioners should be asking to restore metabolic healthResources and Links:Download the full transcript here.Download our FREE Metabolic Health Guide here.

A sudden loss can shake even the most grounded among us.In this deeply personal solocast, Dr. Ritamarie reflects on the unexpected death of a colleague in the natural health community and the vulnerability it surfaced. When someone who appears healthy dies suddenly, it forces a difficult but necessary question: what silent risks might be accumulating beneath the surface?This episode explores the quiet progression of cardiovascular disease, the limitations of standard lab panels, and why doing everything “right” is not the same as measuring what matters. Dr. Ritamarie shares her own experience with elevated lipoprotein(a), what she did in response, and why awareness is not fear, it is responsibility.If you are a practitioner, this conversation is a reminder to screen earlier and look deeper. If you are on your own health journey, it is an invitation to measure what matters before symptoms ever appear.What’s Inside This Episode?Why sudden death in “healthy” people feels different and what it revealsThe silent progression of cardiovascular disease over decadesWhy standard cholesterol panels miss critical risk markersWhat lipoprotein(a) is and why most doctors never test for itHow inflammation, insulin resistance, and endothelial dysfunction quietly accumulateDr. Ritamarie’s personal experience lowering elevated Lp(a)Why genetics influence risk but do not dictate destinyThe difference between helplessness and awarenessWhat practitioners should be screening for now, not laterA powerful question to ask yourself about hidden riskResources and Links:Download the transcript hereDownload our FREE Cardiovascular Risk Assessment GuideJoin the Next-Level Health Practitioner Facebook group here for free resources and community supportVisit INEMethod.com for advanced health practitioner training and tools to elevate your clinical skills and grow your practice by getting life-changing results.Check out other podcast episodes here

Trauma isn't just something that lives in our minds. It has a profound impact on our biology. In this episode, Dr. Ritamarie sits down with Dr. Aimie Apigian, a double board-certified physician and expert in trauma biology, to explore the hidden impact of trauma on metabolism, immunity, and the nervous system. Dr. Apigian explains how unresolved trauma can trigger physical symptoms, including chronic illness.You’ll discover the biological processes that make trauma a root cause of illness, why the body keeps the score, and how trauma creates a feedback loop that keeps people stuck in their symptoms. Dr. Apigian shares actionable strategies for practitioners and self-healers to help break the trauma cycle, understand the body’s response, and guide their clients toward healing.What’s Inside This Episode?How unresolved trauma rewires your metabolism, immunity, and nervous systemThe "Body Trauma Loop": Why trauma keeps you in fight or flightHow childhood trauma shapes adult health, metabolism, and immunityThe 3-phase healing process: From safety to expansionWhy “little T” trauma can be just as damaging as “big T” traumaHow to recognize when trauma is the root cause of chronic symptomsResources and Links:Download the full transcript hereDownload our FREE Guide to Fasting for Health and LongevityJoin the Next-Level Health Practitioner Facebook group here for free resources and community supportVisit INEMethod.com for advanced practitioner training and tools to elevate your clinical skillsCheck out other podcast episodes hereGuest Resources and Links:Dr. Aimie Apigian’s Website: biologyoftrauma.comDr. Aimie Apigian’s Book - The Biology of Trauma: Get the book hereDr. Aimie Apigian’s Podcast: Biology of Trauma PodcastFree Gift: Nervous System Reset - Five Somatic PracticesConnect with Dr. Aimie on Social Media:Instagram: @dr.aimieLinkedIn: Dr. Aimie ApigianYouTube: Dr. Aimie ApigianGuest BioDr. Aimie Apigian, double board-certified physician (Preventive/Addiction Medicine) with master's degrees in biochemistry and public health, revolutionizes trauma healing by revealing how our cells—not just our minds—store trauma.

Most nutrition advice still treats food as fuel, calories to burn, macros to balance, energy to manage. The body doesn’t experience food that way.In this foundational episode, Dr. Ritamarie explains why food is first and foremost information, a powerful metabolic signal that shapes hormones, stress responses, inflammation, and repair, before calories are ever used.You’ll learn why rigid nutrition plans often fail, why the same food can produce opposite effects in different bodies, and how a nutritional endocrinology lens transforms nutrition from mechanical rules into physiological understanding.If you’ve ever followed a “perfect” diet and still felt stuck, or watched good food choices backfire, this episode reveals what’s really happening beneath the surface.What’s Inside This Episode?Why the calorie-and-macro model explains combustion, but not communicationThe signals every meal sends to insulin, cortisol, thyroid, and inflammationWhy the same food can calm one body and stress anotherHow timing, stress, and metabolic state change how food is interpretedThe real reason rigid nutrition protocols stall progressWhat it means to match food choices to the body’s current prioritiesHow nutritional endocrinology teaches you to listen instead of overrideResources and Links:Download the full transcript hereDownload our FREE Functional Food Guide hereJoin the Next-Level Health Practitioner Facebook group here for free resources and community supportVisit INEMethod.com for advanced health practitioner training and tools to elevate your clinical skills and grow your practice by getting life-changing results.

Most people assume metabolic breakdown is due to missing hormones, nutrients, or protocols. The truth? It’s often a misunderstanding of how the body works.In this episode, Dr. Ritamarie explains why chronic metabolic issues aren’t solved by fixing isolated markers, and why systems-level thinking is essential for healing. She introduces nutritional endocrinology and how the body adapts, communicates, and prioritizes survival through interconnected signals.If you’ve ever followed the right protocol, seen lab improvements, and still felt stuck, this episode reveals why and what to do about it.What’s Inside This Episode?Why metabolic health unravels even when nothing appears “missing”The mistake that turns well-intended protocols into stalled progressHow the body actually communicates and why most approaches miss itThe consequences of chasing isolated lab numbers instead of patternsA different way to understand metabolism that explains inconsistencyWhy doing everything “right” can still lead to the wrong outcomeWhat changes when metabolic health is viewed as a system, not a set of partsResources and LinksDownload the full transcript hereDownload our Free Guide to Supporting a Healthy and Balanced Immune SystemJoin the Next-Level Health Practitioner Facebook group here for free resources and community supportVisit INEMethod.com for advanced health practitioner training and tools to elevate your clinical skills and grow your practice by getting life-changing results.Check out other podcast episodes here
