There are cases that don’t resolve the way you expect them to. The labs look reasonable. The protocol makes sense. And yet… something isn’t shifting. In this episode, Dr. Ritamarie sits down with Kim Rogers to explore a layer that’s often debated and often misunderstood—parasites, gut burden, and the role they may play in complex, unresolved cases. This isn’t about assuming parasites are the answe...

Peptides are everywhere: fat loss, tissue healing, gut repair, sleep, hormones, inflammation, brain health, anti-aging, and recovery. The real question isn’t whether peptides influence physiology. They do. The question is: can the body respond? In this episode, Dr. Ritamarie Loscalzo unpacks the hype versus the science behind peptides. You’ll learn why peptides are signaling molecules, why foundat...

GLP-1 medications are everywhere in metabolic health conversations, but weight loss doesn’t equal metabolic restoration. Appetite suppression without strategy can compromise muscle, nutrient status, digestion, and long-term resilience. In this episode, Dr. Ritamarie walks through a functional practitioner’s approach to GLP-1s, including how to protect lean mass, maintain nutrient density, optimize...

The conversation around seed oils is confusing. Some claim they are toxic, while others insist omega-6 fats are harmless. The truth lies elsewhere. The important factors are what the oil contains, how it is processed, and the metabolic health of the person consuming it. In this episode, Dr. Ritamarie Loscalzo cuts through the confusion, unpacking: fatty acid balance, omega-6 to omega-3 ratios, oxi...

You’ve increased estrogen. You’ve supported the gut. You’ve cleaned up the protocol. And… she’s still dealing with dryness. recurrent UTIs., and discomfort that keeps coming back. At some point, it stops being a hormone conversation. When labs look “fine” and symptoms persist, adding more support doesn’t fix the problem. It just exposes it. In this episode, Dr. Ritamarie sits down with Dr. Anna Ca...

What happens when food elimination starts making things worse? You remove the obvious triggers. You follow the labs and the genetics. The plan becomes more precise. Yet… the client becomes more reactive, the range of tolerated foods narrows, and overall resilience declines. This is not a lack of effort. It is a pattern. Food sensitivity reflects the state of the system, not just the food. When str...

You’ve seen cases where everything appears to line up, yet nothing changes. The labs are acceptable. The genetics make sense. The plan is solid, and progress stalls. At that point, most practitioners begin adjusting. When a case stalls like this, the issue is rarely the intervention itself. It is the timing. Genetics suggests what may be needed. Labs show where the system is under strain. Symptoms...

What’s Inside This Episode? Why oxytocin is more than a “love hormone” • The hidden link between oxytocin and digestion, gut motility, and metabolism • How oxytocin influences blood sugar and pancreatic function • Why environmental toxins disrupt oxytocin more than other hormones • The connection between oxytocin, mood, bonding, and emotional resilience • How hormone imbalances contribute to disco...

You’ve seen this before. A genetic report comes back loaded with red SNPs. MTHFR. APOE. COMT, and suddenly everything feels more complicated. More supplements. More restrictions. More second-guessing. That creates overwhelm. In this episode, Dr. Ritamarie breaks down how to actually use genetics in practice without turning it into a list of problems to fix. SNPs aren’t diagnoses, and they don’t te...

HPV gets treated like a life sentence, and the conversation usually stops at fear, procedures, or a vaccine that does not fully protect. In this episode, Dr. Ritamarie talks with women’s health expert Dr. Doni Wilson about what actually drives HPV persistence, why most women are told “there’s nothing you can do,” and how a terrain-based approach helps the body clear high-risk HPV and stay negative...

If you’ve practiced long enough, you’ve seen this. Labs come back “normal,” and yet… the person in front of you clearly isn’t. Fatigue. Brain fog. Anxiety. Metabolic dysfunction. All of these are dismissed, because the numbers fall inside a reference range. Reference ranges are statistical. They are not optimal. In this episode, Dr. Ritamarie walks through how to interpret labs in context by looki...

Activated forms. Methylated forms. Chelated minerals. The supplement world often implies that newer or “activated” means better, but does it? In this episode, Dr. Ritamarie continues the supplementation conversation, this time through the lens of genetics, enzyme efficiency, and precision forms. She breaks down when activated nutrients truly matter, when they don’t, and why choosing the wrong form...

You run the labs and a nutrient comes back low. What’s your first move? For many practitioners, the reflex is simple: replace it. But we’re living in the most over-supplemented era in history. People are taking magnesium for sleep, B12 for energy, iron for fatigue, adaptogens for stress, creatine for cognition without asking the most important question. Why is it low in the first place? That quest...

What if the biggest lever for metabolic health is not another protocol, supplement, or perfect diet? What if it’s the environment people live in, and the relationships that shape daily choices? In this conversation, Dr. Ritamarie speaks with Dan Buettner Jr. of Blue Zones about what the world’s longest-lived populations can teach us, and how entire U.S. cities are applying those lessons through pr...

Creatine is one of the most researched supplements in the world, yet it’s still surrounded by confusion, especially when it comes to kidney health and lab interpretation. In this episode of ReInvent Healthcare , Dr. Ritamarie looks at creatine through a clinical lens. She explains why creatinine levels often rise when someone takes creatine, why that change is frequently misinterpreted as kidney d...

Why do some people experience sound, light, stress, and even social interactions so differently? In this episode of ReInvent Healthcare , Dr. Ritamarie sits down with functional practitioner Dr. Sam Shay to explore what he calls the “neuro-spicy brain.” They unpack how genetics, sensory processing, and nervous system signaling shape the way neurodivergent individuals experience the world. You’ll h...

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 fo...

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 p...

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 understa...

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...

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 chro...

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 nutriti...

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, communicat...
