About the Author
Dr. Doug Fryday is a chiropractor and health coach with decades of clinical experience working with individuals experiencing chronic stress, physical dysfunction, and complex, stress-related health challenges. His work focuses on understanding the body through a nervous-system-first lens, emphasizing the connection between physiology, stress response, and long-term regulation.
Over the course of his career, Dr. Fryday has worked with a wide range of patients, helping them navigate persistent symptoms such as fatigue, pain, anxiety, sleep disturbance, digestive issues, and other conditions often linked to chronic nervous system overload. This clinical exposure led him to recognize a consistent underlying pattern in many of his patients: a state of prolonged physiological stress activation that traditional approaches often failed to fully address.
To better describe this pattern, he developed the concept of Pedal-to-the-Metal Syndrome™ (PTTMS). PTTMS provides a framework for understanding what happens when the nervous system becomes stuck in a sustained survival state, leading to widespread effects across multiple systems in the body. The framework is designed to shift the focus away from symptom management alone and toward a deeper understanding of regulation, safety, and recovery.
In addition to his chiropractic practice, Dr. Fryday has worked as a health coach, guiding individuals toward more sustainable approaches to recovery, lifestyle change, and nervous system regulation. His philosophy emphasizes education over intervention, helping individuals first understand what is happening within their own physiology before introducing tools or protocols.
The InsideOut Lifestyle ecosystem — including the PTTMS framework, apps, educational content, and supporting products — reflects this integrated approach. It is built around the belief that healing begins with a regulated nervous system and that sustainable change comes from restoring safety, balance, and awareness within the body.
Dr. Fryday continues to focus on developing practical, accessible ways for individuals to understand and support their nervous system health in daily life.
