#108 The Best Type of Exercise for Longevity
FoundMyFitness
One minute of vigorous exercise may be worth up to ten minutes of “moderate” cardio for extending lifespan and preventing chronic disease. In this Journal Club episode, Rhonda Patrick, PhD and endurance athlete Brady Holmer dissect a new Nature Communications study of more than 70,000 adults showing that vigorous intensity is roughly 4–10x more potent than moderate activity for reducing all-cause mortality, cardiovascular events, type 2 diabetes, and cancer outcomes—far beyond the long-standing 1:2 rule embedded in global exercise guidelines.

#106 How To Increase Your Testosterone Levels Naturally | Derek from MPMD
FoundMyFitness
When testosterone runs low, libido isn’t the only casualty—muscle mass drops, fat accumulates, insulin resistance rises, and motivation declines. In this episode, Derek from More Plates More Dates highlights common pitfalls that suppress testosterone and evaluates popular testosterone-boosting supplements like Tongkat Ali, boron, and ashwagandha, clarifying what's evidence-based versus overhyped. He also details practical strategies for testosterone replacement therapy (TRT), covering optimal delivery methods, benefits, risks, fertility implications, and key biomarkers to monitor....

#104 Dr. Ben Bikman: How To Reverse Insulin Resistance Through Diet, Exercise, & Sleep
FoundMyFitness
Insulin resistance silently shapes the trajectory of nearly every major chronic disease, yet it's often overlooked until blood sugar abnormalities become obvious. In this episode, Dr. Ben Bikman exposes the dietary culprits that drive metabolic dysfunction and highlights actionable, evidence-based tactics for improving metabolic health. Ben also addresses pressing questions about popular weight loss medications like Ozempic and other GLP-1 agonists: Are they groundbreaking solutions, or shortcuts with hidden metabolic consequences? Timestamps: (0:00) Introduction (4:51) Can you be insulin...

#103 A Deep Dive on Using Coffee For Health & Longevity (Full Guide & Research)
FoundMyFitness
Coffee is one of the most powerful longevity tools we have, potentially reducing epigenetic age by up to one year in regular coffee drinkers, but its effectiveness hinges entirely on how you brew it. In this episode, I outline precisely how coffee reduces DNA damage, a key driver of cancer and cellular aging, and why choosing filtered coffee over methods like French press significantly lowers cholesterol risk. I’ll discuss exactly which beans and roasts pack the highest antioxidant punch, plus a practical tip on a specific supplement that amplifies coffee’s cognitive benefits. You’ll...

#102 Why Vitamin D Deficiency Accelerates Brain Aging
FoundMyFitness
Vitamin D is far more than just a vitamin—it's a potent steroid hormone regulating nearly 5% of our genome. Yet, remarkably, up to 70% of Americans aren't getting enough, placing them at increased risk for dementia and Alzheimer's disease. In this episode, I explore compelling new evidence from a study involving over 12,000 participants, demonstrating that vitamin D supplementation can reduce dementia risk by an impressive 40%, protecting even adults with genetic Alzheimer's risk (ApoE4 carriers). Timestamps: (00:00) Can vitamin D supplements reduce dementia risk? (00:46) How common is...

#100 The Optimal Creatine Protocol for Strength, Brain, and Longevity | Darren Candow, PhD
FoundMyFitness
Creatine is renowned for enhancing strength, but its benefits extend far beyond muscle power. In this episode, Dr. Darren Candow, a leading researcher with over 140 peer-reviewed publications, explores creatine’s diverse physiological impacts, from bolstering cognitive resilience under stress to mitigating symptoms of depression and protecting against cognitive decline caused by sleep deprivation. He explains why the conventional dosage of 5 grams per day might be insufficient, and how higher doses (10–25 grams) could unlock additional therapeutic effects. Timestamps: (00:00)...

#099 The Science of Exercise for Cancer | Kerry Courneya, PhD
FoundMyFitness
For decades, exercise was considered an optional part of cancer care—something beneficial for general health but not essential. The evidence is now overwhelming: exercise is not just supportive—it’s a therapeutic intervention that recalibrates tumor biology, enhances treatment tolerance, and improves survival outcomes. With over 600 peer-reviewed studies, Dr. Kerry Courneya's work has fundamentally reshaped our understanding of how structured exercise—whether aerobic, resistance training, or high-intensity intervals—can mitigate treatment side effects, enhance immune function, and...

Every week, the average person ingests the equivalent weight of a credit card in plastic.* While certain preventive measures can significantly reduce your intake of these harmful substances, it’s crucial to acknowledge a more daunting concern: the bioaccumulation of microplastics in the brain, potentially at ten times the rate of other organs. Microplastics and their associated chemicals are alarmingly ubiquitous — they permeate breast milk, sperm, the hippocampus, the prefrontal cortex, the air we breathe, medications, the water supply, and our bloodstream, accumulating in most major organ systems. During this episode, we’ll explore the unsettling realities of microplastics and their associated chemicals, diving into how they infiltrate nearly every facet of our environment and body, and discuss actionable strategies to reduce exposure.

* Some sources suggesting this figure may need to be revised downward as a result of some disagreement on the math used. However, in spite of this lack of consensus, the human and animal intake of microplastics is substantial and pervasive.
