WHAT IS THE DUAL FUEL REBUILD OPERATIONS MANUAL? The Dual Fuel Rebuild (DFR) Operations Manual serves as the scientific and educational companion to the Dual Fuel Rebuild curriculum. While the DFR website provides implementation, the Phase Manuals provide phase-specific instructions, and the book explains the larger philosophy behind the system, the Operations Manual is designed to explain the underlying concepts, research, and rationale that support the curriculum. Dual Fuel Rebuild is an 8-phase educational framework that teaches participants a series of metabolic, behavioral, and lifestyle tools intended to improve health, body composition, energy regulation, and long-term sustainability. Rather than prescribing a single diet or rigid protocol, the curriculum introduces concepts progressively, allowing participants to build knowledge, skills, and confidence over time. The purpose of this Operations Manual is to provide additional context for the concepts introduced throughout the curriculum. Topics include behavioral psychology, habit formation, circadian biology, metabolic flexibility, dietary diversity, fasting physiology, body composition management, exercise science, recovery, and long-term behavior change. The concepts discussed throughout this manual were informed by established research across multiple scientific disciplines, including nutrition science, exercise physiology, obesity research, metabolic health, behavioral psychology, microbiome science, and educational theory. The manual also highlights researchers whose work contributed to the development of the ideas incorporated throughout the Dual Fuel Rebuild framework. This manual is not intended to function as a medical textbook, clinical guideline, or treatment protocol. Rather, it serves as an educational reference designed to help participants better understand the principles underlying the Dual Fuel Rebuild curriculum.
