WHY I AVOID SEED OILS (AND YOU SHOULD TOO)

THE HEALTHCARE SYSTEM ISN'T WHAT YOU THINK

Most people think doctors and modern medicine are the same thing—but they're not. In this episode of The Body User Manual Podcast, Dr. David Quartell explains the critical difference between doctors, healthcare, and the business of medicine. Learn why modern healthcare excels at treating disease but often struggles to create health, how financial incentives shape the system, and why your daily habits have a greater impact on your long-term health than most people realize. If you've ever wondered why chronic diseases continue to rise despite incredible medical advances, this episode offers a different perspective on prevention, lifestyle, and what it truly means to build health.

YOU'RE ACTIVE... BUT ARE YOU EXERCISING?

Most people think they're exercising when they're really just being active. In this episode, Dr. David Quartell explains the critical difference between activity and exercise, why 10,000 steps aren't enough, and how to train your body for better health, longevity, and metabolic performance.

HOW MODERN FOOD HIJACKS YOUR BRAIN

Modern food isn't just unhealthy—it's engineered to be effortless. In this episode, Dr. David Quartell explains how convenience, hyper-palatable foods, and our environment drive overeating long before the first bite. Learn why cooking is one of the most powerful health skills you can develop and how small changes in food preparation can transform your long-term health.

YOUR IMMUNE SYSTEM NEEDS DIRT

Is being too clean actually making us weaker? In this episode, Dr. David Quartell explores why your immune system needs challenge, adaptation, and appropriate exposure to the world around you. Learn how modern habits may be limiting immune resilience and why health is often built through interaction with our environment—not avoidance of it.

IS ADDICTION RUNNING YOUR LIFE?

Most people think addiction only means drugs, alcohol, or gambling. But what about the everyday habits we know are hurting us—and keep doing anyway? In this episode of The Body User Manual Podcast, Dr. David Quartell explores addiction through a different lens, from sugar and ultra-processed foods to sleep deprivation, stress, and lifestyle choices that quietly impact our health every day.
