Dr. Mark J. Smith graduated from Loughborough University of Technology, England, with a Bachelor of Science in PE & Sports Science and then obtained his teaching certificate in PE & Mathematics. As a top-level rugby player, he then moved to the United States and played for the Boston Rugby Club in 1987-1988 while searching the American college system for an opportunity to commence his Master’s degree.

That search led him to Fort Collins, Colorado, where Dr. Smith completed his Masters degree in Exercise and Sport Science at Colorado State University. He continued his studies in the Department of Physiology, where he obtained his Doctorate. His research focused on the prevention of atherosclerosis (the buildup of plaque in arteries that leads to cardiovascular disease), in particular, using low-dose aspirin and antioxidant supplementation.

As an affiliate faculty member in the Department of Exercise and Sport Science at Colorado State University, Dr. Smith worked extensively with Dr. Loren Cordain, the renowned author of the book, "The Paleo Diet.” As a result of this collaboration, Dr. Smith has had significant experience in helping autoimmune patients improve their condition through diet manipulation. This same diet has also helped individuals lose weight and athletes improve performance. Dr. Smith has also worked extensively as a personal trainer and health consultant and has lectured extensively on the benefits of high-intensity intermittent exercise and Paleolithic nutrition.
