Why do we get sick? In this first lecture of our three-part series on the origins of chronic disease, leading naturopathic physicians Robert Kachko, ND, LAc, and Peter Bongiorno, ND, LAc reveal that many chronic disease progressions are predictable and largely preventable through understanding how lifestyle choices impact our biology. The body has an innate healing capacity. Given the right conditions, it will always move toward health. This lecture shows you how. It isn’t about quick fixes or longevity hacks. It’s about understanding the fundamental framework of why bodies break down and what they need to thrive.

What you’ll learn

  • The chronic disease framework: How strain, repair mechanisms, and dynamic homeostasis determine whether you stay healthy or develop disease
  • Lifestyle as medicine: How sleep, movement, hydration, and nutrition impact mortality more powerfully than any drug on the market (with the data to prove it)
  • The 14-year difference: What the Nurses' Health Study revealed about 5 simple lifestyle factors and their massive impact on lifespan
  • Sleep optimization: Why 7-8 hours of consistent sleep reduces all-cause mortality by 30% and how to achieve it
  • Movement decoded: The Copenhagen Jogger Study's surprising findings—more isn't always better, and 150 minutes of moderate exercise weekly can add years to your life
  • Nutrition that matters: From the MIND diet's 53% reduction in Alzheimer's risk to why fiber, protein timing, and eating pace transform health outcomes
  • Micronutrients reimagined: Why your unique genetics (MTHFR, PEMT, TCN2) determine which vitamins and minerals you actually need

The paradigm shift: Stop asking “what's wrong?” and start asking “why did this person get sick in the first place?” This reframe from reactive medicine to root cause analysis is the foundation of true preventive care.

About the series

The Origins of Chronic Disease: An Integrative Health Perspective is part of the Modern Medicine Series, presented by the Atria Health and Research Institute. These videos share a three-part framework for understanding why people get sick through biology (how you live), ecology (the conditions in which you live), and biography (what you’ve lived through). Atria’s Integrative Health team explains that chronic disease is predictable, and largely preventable, when we address the root causes rather than just treating symptoms.
