Sweaty AF Podcast

In this episode, I sit down with Dr. Martin Moore-Ede, a world-leading expert in circadian biology and the founder of Circadian Light, to explore how artificial light has quietly but profoundly reshaped human health.

We live in a 24-hour society, surrounded by screens, LED lighting, and indoor environments that disconnect us from the natural rhythms our biology evolved with. Dr. Moore-Ede explains how this shift has altered our circadian timing systems, impacting everything from sleep and metabolism to immune function and long-term disease risk.

We dive into why circadian rhythms regulate far more than just sleep. They control hormonal balance, appetite, glucose metabolism, inflammation, cognitive performance, and even cellular repair. When these rhythms become disrupted, whether through jet lag, late-night screen exposure, or shift work, the consequences ripple throughout the body.

We discuss the science behind jet lag and why it feels so destabilizing, not just mentally but metabolically. We explore how mistimed light exposure can increase hunger, alter insulin sensitivity, and contribute to weight gain. For shift workers, who experience chronic circadian misalignment, these risks can compound over time.

Dr. Moore-Ede also clarifies the truth about blue light. It isn’t inherently “bad” in fact, blue-enriched light during the day supports alertness, mood, and cognitive function. The issue is exposure at the wrong time. He explains when blue light blocking glasses can be helpful, how to use them properly, and why daytime natural light exposure is essential for learning, mental clarity, and overall resilience.

We also touch on one of the most fascinating areas of his work: hospital lighting. Emerging research shows that circadian-aligned lighting in healthcare settings can improve recovery times, strengthen immune response, and support better patient outcomes. Optimising light may be one of the most overlooked longevity interventions available today.

For midlife women in particular, this conversation is powerful. As we move through perimenopause and menopause, circadian rhythms can become more fragile. Sleep disruption, weight changes, mood shifts, and inflammation are often amplified by poorly timed light exposure. Understanding how to structure your light environment may be one of the simplest yet most effective tools to restore energy, improve sleep quality, and protect long-term brain health.

This episode will change how you think about light. It’s not just about brightness, it’s about biology.

In this episode of Sweaty AF, Lucy sits down with Zorrie Dimitrova, Chief Operating Officer of GlycanAge, to explore the science of biological aging and why inflammation is one of the most overlooked drivers of how fast we age.

Zorrie shares her deeply personal journey, from growing up on a farm with a naturally healthy lifestyle, to facing unexpected health challenges that pushed her to look beyond traditional health markers. That search ultimately led her to glycan age testing, a breakthrough that revealed hidden inflammation in her body despite “doing all the right things.”

Zorrie unpacks what glycans actually are, how they influence inflammation and immune function, and why glycan age can tell a very different story compared to other biological age tests. Zorrie explains how stress, gut health, lifestyle consistency, and diet all directly impact glycan patterns, and how small, sustained changes can meaningfully reverse biological aging over time.

The conversation also dives into powerful real-world success stories from people who have tracked and improved their glycan age, highlighting the transformational potential of understanding your body at a deeper, more personalized level.

This episode is a must-listen for anyone interested in longevity, autoimmune health, inflammation, and using data, not guesswork, to age better.

In this episode, I’m joined by McCall McPherson, a physician assistant, thyroid patient, and founder of Modern Thyroid Clinic, for an in-depth conversation on thyroid health, hormones, and metabolic medicine.
McCall shares her personal journey navigating thyroid dysfunction and how her own experience within the healthcare system led her to create Modern Thyroid Clinic, a patient-first model focused on proper testing, personalised treatment, and long-term health outcomes.
We discuss why thyroid disorders are so often missed or misdiagnosed, particularly in women, and why relying on TSH alone is rarely enough. McCall explains the importance of testing free T3, thyroid antibodies, and the full clinical picture, especially for women in perimenopause and menopause who are often told their symptoms are “just hormones.”
The conversation also explores the expanding role of GLP-1 medications, not only for weight loss, but for metabolic health, inflammation reduction, longevity, and disordered eating patterns. McCall shares why micro-dosing GLP-1s can help minimise side effects while improving results, and why individualised protocols matter far more than one-size-fits-all approaches.
This episode is essential listening for anyone who has been told their blood work is “normal” while still feeling exhausted, inflamed, or stuck, and for women who want to better understand their thyroid, hormones, and metabolic health.

Health Optimization, Preventative Wellness & The Future of Functional Medicine
In this episode, I’m joined by Sam Tejada, President and Founder of Liquivida, for a grounded, science-led conversation on what true health optimization actually means in a world obsessed with aesthetics, shortcuts, and trends.
Sam shares his personal journey from working as a lifeguard to emergency medicine, and ultimately into functional medicine, after witnessing first-hand the critical gaps in our healthcare system, particularly when it comes to prevention and early detection. Rather than reacting to disease, Sam’s work focuses on identifying imbalances early and creating sustainable, long-term health outcomes.
We explore why preventative wellness must be the foundation of modern healthcare, and why the basics, nutrition, movement, and sleep , are still the most powerful tools we have. Sam explains how tracking biomarkers provides clarity and direction, allowing individuals to make informed decisions rather than chasing trends or relying on guesswork.
The conversation also dives into stress management and nervous system regulation, the often-overlooked role of community and connection in longevity, and why weight loss alone is a poor marker of health if function, energy, and resilience are compromised. Sam contrasts aesthetic-driven goals with true functional health, highlighting the importance of mitochondrial health for sustained energy, performance, and ageing well.
We also unpack current wellness trends, including why alkaline water offers little therapeutic benefit, how molecular hydrogen differs, and why data, not dogma, should guide health decisions. Sam shares his personal non-negotiables for health, emphasizing the importance of learning what to say no to, not just what to add.
Finally, we focus on one of the most underestimated pillars of longevity: sleep. Sam explains why preparing the body to sleep is just as important as sleep itself, and how consistent sleep hygiene underpins everything from hormone balance to long-term performance.
This episode is a powerful reminder that optimal health isn’t about doing more, it’s about doing what works, consistently, and with intention.
