Mark Simpson, Ph.D., is an academic administrator and the Vice President for Academic Services at Rockbridge International Seminary. Drawing on both professional discipline and personal experience, he writes on practical strategies for lasting weight management and healthy living. After years of struggling with weight, he adopted evidence-informed nutrition and lifestyle practices designed to support metabolic health and long-term consistency. Using this approach, he lost 140 pounds over the course of one year. In Road Map to a Healthy Eating Lifestyle: How to Reach Your Weight Goals and Keep the Weight Off, Dr. Simpson presents healthy eating as a sustainable way of life rather than a temporary or restrictive plan.

He uses a road map framework to explain how daily routines, food quality, and consistent decision-making can support steady progress and long-term maintenance. Written with the structure of an educator and the perspective of a fellow traveler, his work is intended to help readers understand the role of metabolism in weight management and to apply practical principles that support lifelong healthy eating habits.
