In this episode, Laurel and Sarah are joined by Dr. Joe Schwarcz, Director of the Office for Science and Society at McGill University and one of the most experienced science communicators working today. They explore why pseudoscientific health claims spread so effectively, even among educated and well-intentioned people, and why wellness culture is so drawn to simple explanations for complex biological problems.

The conversation moves through three dominant narratives shaping modern health messaging: the obsession with finding a single root cause, the moralization of food, chemicals, and health behaviors, and the pressure to optimize every biological variable imaginable. Dr. Schwarcz explains how these narratives distort public understanding of science, create unnecessary anxiety, and distract from the few behaviors that reliably matter for health, like movement, nutrition, and basic risk management.

They also discuss how science actually works, including why it changes over time, how peer review can fail, how industry funding complicates research interpretation, and why cherry-picked studies and observational data are so easily weaponized in marketing. The episode closes with practical guidance on how to evaluate health claims, how to think about trust and expertise, and why asking better questions is often more powerful than finding definitive answers.

122: A Science Communicator Explains Pseudoscience, with Dr. Joe Schwarcz, PhD

In this solo episode, Sarah takes the “doctor vs brand” framework that went viral on Instagram and runs it as a real-time case study on a real company. The target is Cadense, an adaptive shoe that claims to help with foot drop, toe catch, and neurologic walking difficulties using “variable friction” tech, basically a glide-to-grip outsole design meant to reduce toe snagging while still giving traction during stance and push-off. Sarah breaks down what foot drop is, who this type of device might help, who it might put at risk, and why any rehab-adjacent product should be judged on more than vibe, testimonials, or white-coat authority.

Then she gets into incentives, the part everyone wants to ignore until it’s their wallet. She walks through Cadense’s ambassador, coach, and affiliate pathways, and uses the full checklist to evaluate where Cadense lands on the clinician-led spectrum, including what they disclose well, what they oversimplify, and what they should tighten up if they want to be truly “do no harm” about a product that can literally change someone’s fall risk. Finally, Sarah looks at the actual research (yes, it exists, no, it’s not robust yet), explains what a five-person pilot study can and can’t prove, and lays out the line she personally won’t cross, recommending a product case-by-case versus becoming financially tied to a medical-ish purchase decision.

121: Do No Harm, But Also Sell Shoes? The Doctor vs Brand Problem

In this episode of the Movement Logic Podcast, Laurel Beversdorf revisits the advice to eat 30 different plants per week and explains why it sounds scientific while resting on a much shakier foundation than it appears. She reflects on encountering the claim, why her and Sarah’s initial reaction was skepticism, and how listener feedback led to a closer look at where the idea came from and how it spread.

Laurel breaks down what the American Gut Project actually showed: an observational association between self reported plant variety and gut microbiome diversity in a specific, self selected, largely affluent cohort. She explains why this type of research cannot identify an optimal number of plants or justify turning a statistical cutoff into a universal lifestyle rule, especially given the limits of how plant intake was measured.

She then examines how the venture backed consumer health company Zoe translated this association into a prescriptive target and built products around it, arguing that the clarity and certainty of the message functions as marketing rather than sound, science backed health advice. Finally, Laurel zooms out to the emotional and social impact of this advice, explaining how moralized wellness claims turn health into a performance metric while ignoring access, instability, and other social determinants of health.

120: Is Advice to Eat 30 Different Plants/Week Science-Backed?

Testosterone is everywhere in menopause conversations right now, often framed as a solution for everything from low energy and brain fog to bone health and longevity. In this episode, Dr. Sarah Court, PT breaks down what actually matters when it comes to testosterone for menopausal women, separating social media hype from clinical evidence. The real questions are not whether women have testosterone or whether levels change with age, but whether testosterone should be prescribed, for whom, and what the data truly supports.

Using current consensus guidelines, this episode explains why testosterone has one narrow, evidence-based indication, hypoactive sexual desire disorder, and why claims about mood, energy, cognition, bone health, and longevity are not supported by high-quality research. Dr. Court also walks through how testosterone is prescribed in the real world, why the lack of FDA-approved products for women creates problems, and what the safety data does and does not tell us about long-term risks. If you have heard confident claims about testosterone as a menopause cure-all, this episode provides the context you need to evaluate those messages with clarity and skepticism.

119: Testosterone in Menopause: What We Know, What  We Don't

In this episode of the Movement Logic Podcast, Laurel and Sarah talk with registered dietitian and longtime myth buster Abby Langer, RD, about what it actually means to eat in a healthy, sustainable way. Abby brings clarity to some of the most confusing and overhyped nutrition messages online, explaining the meaningful difference between dietitians and nutritionists, why food guidelines get so much misplaced blame, and why simple habits like eating more fiber, plants, and whole foods still matter far more than clean eating, hormone-balancing diets, or supplement-driven solutions. She breaks down ultra processed foods, weight gain misconceptions, what causes overeating, and why carbs, fruit, sugar, and seed oils have all become targets of unnecessary fear.

The conversation also explores protein needs, plant versus animal protein, the role of fiber in digestion and satiety, what gut health is and isn’t, and why probiotic claims are often overstated. Abby shares how her decades of experience in hospitals, primary care, and private practice have shaped her evidence-based approach, and she offers grounded advice on how to build a sane, less anxious relationship with food in a culture that thrives on extremes.

118: How Should We Eat To Be Healthy? With Abby Langer, RD

In this episode of the Movement Logic Podcast, Sarah discusses two primary methods for measuring bone density: DEXA (Dual-Energy X-ray Absorptiometry) and REMS (Radiofrequency Echographic Multi-Spectrometry). The episode explains what each method measures, their technologies, reliability, and practical applications. It compares their availability, cost, accuracy, and limitations. DEXA is recognized as the clinical gold standard but has some limitations, while REMS, although newer, shows promise with advantages in certain clinical situations.

117: DEXA vs REMS: What's the Difference?

In this episode of the Movement Logic Podcast, Laurel Beversdorf talks with strength coach James Lederach, MS, CSCS, about the deeper side of coaching and how helping someone get stronger often means helping them grow as a person. Together, they explore the benefits of strength development for adults and kids, training that supports rather than interferes with sport, the downsides of early sport specialization in youth, and the broader life lessons that strength training offers beyond physical health and performance.

James and Laurel reflect on how training develops resilience, self-reliance, and emotional steadiness for both kids and adults. They discuss how good coaching balances structure with empathy, how strength training teaches self-trust, and why the most meaningful outcomes of training have less to do with performance and more to do with who we become through the process.

116: Coaching Strength, Building Character with James Lederach, MS, CSCS

In this episode of the Movement Logic Podcast, Laurel Beversdorf and Dr. Sarah Court examine the enduring myths and misinformation around the aesthetic goal of “getting abs.” They analyze the anatomy and function of the abdominal muscles, the cultural evolution of ab training versus core strength and stability training, and the role mechanical tension, muscle length, and training volume play in hypertrophy (muscle growth). Additionally, they discuss how pursuing the aesthetic goal of "getting abs" is different from performance goals related to abdominal strength.

The hosts unpack popular misconceptions, such as “abs are made in the kitchen,” or that body composition changes work differently for women than men, or that core stability means never moving your spine. They contrast these myths with what current research on energy balance and hypertrophy training show. They also trace how Pilates, physical therapy, and social media helped shape the modern core strength and stability narrative—one that, in some circles, shifted from building strength through movement to “protecting” the lumbar spine by avoiding it.

Additionally, this episode aims to clarify all of the factors that influence the appearance of the abdominal region, and how gendered, moralized, and shame-based messaging about the midsection continues to distort public understanding of exercise and body image.
