In this special 100th episode of Hormones, Metabolism, and You, Dr. Cassie Smith celebrates the milestone with a best-of compilation featuring some of the most downloaded and impactful conversations from the show. Each segment reflects a powerful truth listeners continue to come back to: when you feel off, there is usually a biological reason, and real answers start with understanding the root cause.
You will hear highlights from key conversations, including:
Tamar Samuels: Debunking common nutrition myths and social media trends, including restrictive “one-food” weight loss approaches and the confusion around anti-diet culture. This segment emphasizes personalized nutrition, metabolic health, and the importance of sustainable habits that support both body composition and long-term health.
Terri DeNeui: A powerful discussion on hormone therapy in your 30s, 40s, and 50s, including the truth about estrogen and cancer risk. This segment breaks down the long-term misunderstanding from the Women’s Health Initiative and explains why timing, personalization, and proper hormone support are critical for brain, heart, bone, and overall longevity.
Dr. Bruce Hoffman: A deep dive into chronic fatigue, mitochondrial dysfunction, and the concept of the cell danger response. You will learn why energy production is central to healing and how factors like toxic load, circadian rhythm, sunlight exposure, hydration, and lifestyle habits directly influence mitochondrial health and recovery.
Dr. Cassie Smith (Solo): A practical breakdown of thyroid optimization, including ideal functional ranges for TSH, Free T4, Free T3, Reverse T3, and thyroid antibodies. This segment explains why symptoms matter more than standard lab ranges and how inflammation, gut health, stress, and cellular function affect thyroid hormone activity.
Dr. Tyna Moore: An insightful conversation on GLP-1 microdosing and peptide therapy beyond weight loss. This segment explores how low-dose GLP-1s can support brain health, inflammation, metabolic function, and longevity, while also highlighting the importance of gut health, hormone balance, and foundational lifestyle habits before using advanced therapies.
Together, these listener-favorite moments reinforce the core message of the show: you are not broken, your symptoms are not random, and lasting change happens when you address the biology behind the symptoms.
Key Takeaways
This special 100th episode highlights a core theme across listener favorites: when symptoms don’t match normal labs, the issue is often deeper biology, not willpower. Sustainable health requires personalized nutrition, strong lifestyle foundations, and attention to real markers, not trends or extremes. Hormone therapy fears are often based on outdated information, thyroid care goes beyond TSH alone, and tools like GLP-1s work best as supportive therapies, not shortcuts. The consistent message throughout is safety-first, root-cause care with the right intervention at the right time.

More from Hormones, Metabolism & You!
Dr. Anna Cabeca joins me to talk about why so many midlife women are told their labs are normal while they feel exhausted, foggy, and out of step with their own bodies. We talk about what shifts in perimenopause, how falling progesterone and insulin resistance can show up as everyday symptoms, and why Dr. Cabeca treats hormone imbalance as a metabolic question first.
What if I told you right now, this very moment, your body is carrying a chemical load that you have never been tested for, never been warned about, and never asked for? In this episode, I’m joined by Nick Pineault, author of The Non-Tinfoil Guide to EMF and creator of the documentary Body Burden: The Toxins We Carry, to talk about what “body burden” actually means and how the chemicals we encounter through our food, water, air, plastics, household products and technology may intersect with hormones, metabolism and overall health.
Dr. Monisha Bhanote joins me to talk about cellular health and resilience, and why fatigue, brain fog, digestive issues, and other everyday symptoms may be signals from our cells rather than things we should simply accept. We talk about her approach to cell care, cellular consciousness, and why health practices need to be personalized rather than copied from the latest trend.
What happens when you’re doing all the “right” things for your hormones and health, but you still don’t feel better? In this episode, I sit down with Dr. Neil Nathan to explore why underlying factors like mold, Lyme disease, inflammation, nervous system dysregulation, and detoxification challenges may complicate treatment.
Testosterone in women is finally getting more attention, but what does that actually mean for women and their care? In this episode, I sit down with Dr. Terri DeNeui to discuss the FDA’s focus on testosterone, why there still isn’t an FDA-approved testosterone treatment specifically for women, and the questions surrounding safety, dosing, and access.
