Burnout isn’t just about feeling tired, it’s a biological signal your body has been trying to send. In this solo episode of Treated, Dr. Sara unpacks the 7 key biomarkers every woman should track to understand and prevent burnout. From heart rate variability and cortisol patterns to thyroid function, progesterone, and sleep quality, she reveals why the usual metrics– steps, calories, and bathroom scales– miss the bigger picture of what’s really happening inside your body.

Dr. Sara explains how subtle shifts in hormones, sleep, and blood sugar often appear long before fatigue, brain fog, or mood changes set in. She breaks down how to measure these “burnout biomarkers” in ways that give you actionable data, helping you move from overwhelm to resilience. If you’ve ever felt like exhaustion was “all in your head,” this episode offers a science-backed framework to decode your body’s signals and create a path to true recovery.

Women’s health expert Cynthia Thurlow returns to Treated to unpack one of the most misunderstood wellness trends: intermittent fasting. Together, Dr. Sara and Cynthia explore why fasting can stop working—or even backfire—for women over 35. From blood sugar crashes and burnout to the loss of lean muscle, they reveal how stress, hormones, and timing shape a woman’s fasting success. Cynthia shares how her own approach evolved through perimenopause, why she swapped strict fasting for “digestive rest,” and how she rebuilt strength and energy by eating more protein, lifting heavy, and embracing carbohydrates.

The conversation goes into the science of metabolic health, hormones, and sensitivity—connecting fasting, cortisol, estrogen, and emotional resilience in midlife. Dr. Sara and Cynthia discuss how highly sensitive women and those navigating perimenopause need tailored approaches to stress and nutrition, not one-size-fits-all biohacks. They also touch on the promise and pitfalls of peptides and GLP-1 medications, the importance of sleep and social connection, and why strength is the ultimate marker of longevity. It’s a grounded, science-backed guide to thriving—not just surviving—through hormonal change.

Today, Dr. Sara sits down with Biet Simkin for an unflinching and soulful conversation about trauma, transformation, and the pursuit of true sovereignty. Known for blending spirituality with art, music, and radical honesty, Biet opens up about losing her mother at six, the compounding grief that shaped her early life, and how she transmuted that pain into a spiritual practice. Together, they explore what it means to live not in spite of what breaks us, but because of it—and how awakening can coexist with mess, humor, and humanity.

As their conversation unfolds, Biet shares the evolution of her path from addiction and loss to creating a modern spiritual framework that bridges humility and power, faith and agency. She challenges listeners to examine whether they’re living at 80% of their potential—and what it would take to move toward 100%. From the psychology of trust and the biology of regulation to the sacred art of self-responsibility, this episode is a masterclass in transforming suffering into service and living a fully expressed life.

Today Dr. Sara explores one of the most misunderstood symptoms in women’s health: brain fog. She unpacks why the mental haze so many women experience isn’t “just stress” or “getting older,” but often a biological signal of deeper dysfunction—spanning hormones, mitochondria, inflammation, and metabolism. From postpartum to perimenopause to menopause, Dr. Sara traces how shifting estrogen, nutrient depletion, and chronic stress can dim the brain’s energy output—and how to reverse it. She offers a step-by-step roadmap to restore mental clarity, reboot energy, and reclaim focus at every stage of womanhood.

What if your midlife wasn’t a breakdown, but a biochemical initiation? Today on Treated, Dr. Sara dives into the truth about perimenopause by dispelling the myths, breaking down the science, and reframing this transition as a powerful initiation rather than a decline. She explains what’s really happening with your hormones and how to navigate symptoms like mood swings, insomnia, and heavy cycles with compassion and strategy. From practical tools like cycle tracking, nutrients, botanicals, and bioidentical hormones to her “soft landing plan” for midlife, Dr. Sara offers both medical expertise and soulful perspective. This is an invitation to see perimenopause not as the beginning of the end, but as the beginning of a deeper, wiser chapter.

What if your symptoms like fatigue and burnout aren’t just about stress or overwork, but your hormones waving a white flag? In this episode of Treated, Dr. Sara sits down with nurse practitioner and nutritionist expert Cynthia Thurlow to unpack the hidden drivers of midlife burnout, fatigue, and brain fog. Cynthia shares her own journey from practicing traditional cardiology medicine to navigating a full burnout in her early 40s – a turning point that reshaped not only her personal health but also her entire career. Together, they explore why so many women feel dismissed by conventional lab work, the role of hormones like progesterone and cortisol, and why biomarkers such as fasting insulin, HRV, and thyroid function can reveal what’s really going on beneath the surface.

Cynthia and Dr. Sara highlight the science of metabolic flexibility, cardiovascular risk markers like lipoprotein(a), and the connection between stress, trauma, and hormones. They also touch on the importance of alignment, meaning, and boundaries in preventing burnout – reminding us that midlife can be a time of initiation and transformation rather than decline. If you’ve ever wondered whether your fatigue is “just stress” or something deeper, this episode offers the tools and insights to measure what truly matters.

Most people assume “normal” lab results mean they’re in the clear but normal isn’t always optimal. In this episode, Dr. Sara breaks down why standard blood work often misses early warning signs of disease and what that means for your long-term health. She shares the story of a patient whose labs came back “fine” but were already showing signs of pre-diabetes, and explains how the difference between surviving and thriving often lies in catching subtle markers before they become a diagnosis.

Dr. Sara walks through nine essential tests that go beyond the basics, from vitamin D and ferritin to thyroid, sex hormones, inflammatory markers, and genetic risks like lipoprotein (a). These underused but powerful tools reveal whether your fatigue, brain fog, or mood issues are rooted in overlooked deficiencies or brewing imbalances. With decades of experience in longevity medicine, Dr. Sara shows how the right labs can transform your understanding of health and help you take action now because prevention is power.

What if the real medicine isn’t about conquering death, but about learning how to live fully in its presence? In this conversation, Dr. Sara sits down with two close friends and colleagues, Dr. Kara Fitzgerald, a trailblazer in epigenetics and author of Younger You, and Dr. Patrick Hanaway, a physician and wisdom teacher whose own journey with cancer reshaped his perspective on life. Together, they challenge the cultural obsession with “not dying” and the reductionist biohacking narrative, offering instead a counter-narrative: don’t miss it.

They explore the fears we carry about aging and how embracing impermanence can actually deepen our vitality. With stories of their families, patients, and personal journeys, this is a heartfelt, thought-provoking dialogue that challenges the more common “don’t die” narrative in longevity. 

This is only part of their conversation. Listen to the full conversation for free by attending the virtual “Functional Medicine is Longevity Medicine: A Masterclass for Clinicians” September 17-19, 2025.
