In this episode of Walk, Don't Run to the Doctor, Miles Hassell MD explains why optimal health starts in your own kitchen. While many people search for health shortcuts through supplements, special testing, weight-loss medications, and wellness trends, the evidence points to a much simpler solution: cooking more of your own meals using real, minimally processed foods.

Dr. Hassell discusses how home-cooked meals can reduce the risk of chronic disease, improve weight management, save money, and help create lifelong healthy habits. He also shares practical strategies for learning to cook, planning ahead, and making healthy eating realistic even with a busy schedule.
