Everything You've Ever Wanted To Know About Fish Oil, Omega 3 Fatty Acids, EPA, DHA & Much More!

In this episode with Dr. Joel “Gator” Warsh, you’ll discover a balanced perspective on vaccines, especially childhood vaccination, at a time when open, evidence-based dialogue is more important than ever. Drawing on his work as an integrative pediatrician, Dr. Warsh shares insights from his new book Between a Shot and a Hard Place, designed not to fuel division but to empower parents with knowledge, research, and practical tools for making informed decisions. You’ll explore the origins and evolution of vaccines, how schedules have changed, the strengths and flaws of safety testing, the nuanced risks and benefits of individual shots, and the importance of informed consent and medical freedom. By weaving together mainstream medicine and holistic practices, Dr. Warsh highlights where the science is strong, where questions remain, and why open conversation is the path toward clarity, confidence, and compassion—and if you’re interested in cutting through fear and hype to understand this complex topic, you won’t want to miss this episode. Dr. Joel "Gator" Warsh is the creator of the parenting Instagram account @drjoelgator and a board-certified pediatrician in Los Angeles specializing in wellness and integrative medicine. He is the author of multiple books, including his latest Between a Shot and a Hard Place: Tackling Difficult Vaccine Questions with Balance, Data, and Clarity. He grew up in Toronto, completed a master’s in epidemiology before earning his medical degree at Thomas Jefferson Medical College, and trained at Children’s Hospital of Los Angeles before founding Integrative Pediatrics. Dr. Warsh has published research in peer-reviewed journals on childhood injuries, obesity, and physical activity and has been featured in documentaries, summits, podcasts, and articles.

In this episode we dive into a hotly debated topic: should you eat meat or not? Ben is joined by two powerhouse guests with decades of experience in nutrition and health—Dr. Shawn Baker, best-selling author of The Carnivore Diet and leading carnivore advocate, and Joel Greene, creator of The Immunity Code and champion of dietary diversity. In this spirited debate, Dr. Baker highlights the benefits of a strict carnivore approach—meat, eggs, some dairy, and minimal plant foods—not only for himself but also for patients managing chronic health issues. He explains why animal-based nutrition can be so effective, breaks down the science of ketosis and gut health, and responds to concerns about long-term effects of fiber-free diets. Meanwhile, Joel Greene makes the case for dietary variety, drawing from evolutionary biology, clinical research, and personal experience. He explores the synergies of combining animal and plant foods, the role of fiber in gut and immune health, and the ancestral rhythms of scarcity and feasting. Joel argues that even small amounts of diverse foods can offset downsides of strict elimination diets. Dr. Baker is a physician, athlete, and author known for his straightforward, meat-focused approach to nutrition and his background in strength sports. Joel is the creator of Veep Nutrition, a program targeting gut communities to improve health, used by major employers and featured on the Dr. Phil Show. Author of The Immunity Code, Joel has devoted 50 years to health and anti-aging, pioneering practices like MCTs in the ’80s, keto in the ’90s, and AMPK activation by 2009. At 55, he remains a 100% natural athlete.

In this episode, Emily Kaplan—co-founder of the Broken Science Initiative (BSI)—pulls back the curtain on systemic flaws undermining modern research. From manipulated data in high-impact journals to misuse of peer review and statistical tools like p-values, Emily reveals how corruption and misconduct shape medicine, including the infamous Alzheimer’s study that misled treatment development for years.

One key effort is MetFix, a grassroots initiative empowering communities to prevent and reverse chronic disease with nutrition and lifestyle interventions. Emily brings deep expertise in strategy and communication.

Through in-person and online events, BSI fosters communities committed to what’s working—and exposing what’s broken—in modern medicine. Her career spans journalism, entrepreneurship, and high-level advising. She co-founded The Kleio Group, guiding companies, celebrities, and politicians through strategic communication and crisis. She previously scaled Prep Cosmetics into a national chain, co-developed one of the first geolocation-based dating apps, and founded Prime Fitness and Nutrition, a women’s health concept with three locations. Emily has also hosted the Empowered Health Podcast, authored two books with HarperCollins Leadership, and contributed to ABC News, Boston Magazine, and major outlets. With degrees from Smith College and Northwestern, plus advanced studies at Harvard Law, Emily blends business acumen, investigative rigor, and a passion for performance.
