Why Dr. Mike Created This Course
Dr. Mike T Nelson built the Flex Diet Certification to turn cutting-edge research into practical coaching tools. After years of watching clients struggle with rigid nutrition plans and oversimplified advice, he created a physiology-first system that gives coaches the tools to help more people succeed.
With a PhD in Exercise Physiology, an MS in Biomechanics, and decades of teaching and coaching experience, Dr. Mike has worked with everyone, from elite athletes to military personnel to everyday clients. Known for turning complex science into practical strategies, he brings evidence-based insights from research, teaching at the Carrick Institute, and active membership in professional organizations like ACSM and ISSN directly into this course.
